Physical Sim user here. The great thing about Sim cards is that you can easily move them from one device to another (for most carriers) without having to contact customer support. Going on a rough trip (say, boating)? Move your Sim into a beater phone that you don't care if it gets destroyed or drowned. Esim makes that use case more difficult, as you would have to contact customer service twice for that case.
@harrkev Lucky, I've tried doing that, from my glue-melted-new-phone to my previous removable battery phone, & they thought I was doing something bad then they nuked the card or service, old was not working, tried putting it in the new-half-working-phone still didn't work, went back to old didn't work.
Still on physical sim. Heard about esim when I was abroad recently. Your explanation and summary was clear and simple to follow so thankyou. Really tells me what would be helpful for me if I purchase a new phone and be able to have dual phone numbers in order to receive text messages from country of residence have another phone number to take calls etc.... while abroad.
eSIM is good until I broke my phone. It was not easy to recover it as you would need a spare phone with eSIM to transfer it while waiting for your original phone to get repaired. While it was only my secondary number but the pain of not having a physical SIM to just pop into another phone really makes me rethink the pros and cons of eSIM. Luckily I got my original phone replaced immediately when sent for repair hence the downtime ended up being shorter than expected. :)
This is my one of my major concern with eSIMs, also how will changing operators (porting out) will work - what if the existing operator is not willing to 'cooperate' ...
Excellent information. Good job Gary, just a quick question. Is it possible to maintain the same cell phone calling number while re-programing or subscribe a different user company on the same e-sim card. Example during travelling internationally.
All makes sense however you talk about eSIM like its a choice over the old SIM however state it is built in. You also say it frees up space for other components however lots of new phones came with a nano sim spot and built in eSIM. Also, and most importantly, Can a small eSIM chip be purchased to make older phones compatible with eSIM?
Thank you for this comment, i had a feeling cost cutting prepaid phones would have that, & I've wondered why some cheap looking phones were missing the SIM card tray
In my opinion, the esim is the way the network will further control and limit user experience. Only phones they see as acceptable to the network will be allowed to function on the network. For example, phones that are imported to here in the US don't utilize the esim so they would be out and networks could further limit things to only devices that they sell. This limits your choices as to which phones you use.
@@Lanon0987654321 Possibly, but if they work/collude with phone manufacturers, like Apple and Samsung, they can make it happen a lot faster. Thereby limiting our choices to a handful of devices.

updated to a newer iPhone (forget version) and have not activated due to not working when following instructions from my carrier. This seems to be some artifact of the Sprint merger and hitting some edge case. So currently I am a regular SIM user on an iPhone 11 waiting to use my newer eSim-enabled iPhone still it its box.

My s10e is the traditional sim card. I just upgraded to the G S23 Ultra. I'm just getting hip to eSIM. At the moment I'm having a hard time trying to remove my sim card❓🤔. So I hope I don't have to add the sim card from my s10e to my Gs23 Ultra..
Just a thought. There are over 30 million used phones sold every year, so with an Esim how does that work when the Esim is locked to the original purchaser?
Is the QR code provided only valid until Esim activivated? Just thinking of criminals that might make a copy of the QR code and trying to activate it on other devices as well.
@@GaryExplains eSIM takes SIM-locking to a new level. I saw a screenshot from an iPhone that went something like "your phone can't add this data plan". In some cases, one needs to contact the carrier for the device to be eSIM equivelant to "SIM unlocked'. in case of iPhone, eSIM can also be artificially limited to some carriers (i read some posts on this), making the device worthless when travelling internationally. eSIM can also bypass some current laws that forbid SIM locking. It's not really the eSIM technology itself I have a problem with in this regard but the new potential to limit the consumers' freedoms it brings.
I have the pixel 6 pro with E-sim capability. But I was wondering if I say use a physical SIM and an E-sim ( activated). I was wondering if I could add More carriers to the e-sim and essentially have a triple SIM and use/activate each one depending on the needs? so not necessarily simultaneous use of all 3.
Thanks for the explanation. In theory, with an eSIM, it should be possible to use the same SIM across multiple devices so you can have a single phone number that can be used across multiple devices for phone calls and messages, right? Like how it can be shared between an Apple watch and an iPhone (subject to carrier support). So why isn't it advertised as such? Any security concerns there? Would love it if Gary explains this as well :)
It’s possible with regular SIM as well. A SIM is nothing but an identifier just like an Email Address is. You can get Emails pushed to all of your different devices, and the same is possible with SIM/Phone #. Here in the US, Telecom companies charge monthly fees to use the service. T-Mobile has digits; AT&T has NumberSync; and Verizon has Number-Share.
Visible is a carrier that offer esim (but only to select Apple products the last time that I checked), and they are pay as you go. On the other hand, since they don't do retail stores, they FedEx a Sim to you when you sign up, so that must cost quite a bit.
I don't think eSims caught up much in my country so far, though I think they must be a thing for iPhone users... vast majority of people won't be on latest flagship devices though, it's mostly older mid range to low end down here, so most of them won't be compatible with eSims. Heck, I don't think most people even jumped towards USB-C just yet... I still see a lot of people carrying smartphones with microUSB ports. :P There is just one thing I don't like much about eSims, and that's uniqueness and portability. I think this is different to some other countries, maybe someone else will be able to explain and compare this better than myself. But at least afaik, here where I live a Sim card is unique. You cannot have 2 Sim cards with the same number, so it's kind of a deterrent for cloning and whatnot. I have also moved my SIM card from one device to another for different use cases... eg. from smartphone to tablet to smartwatch. It's a hassle, and rare case, but just temporary measure. The thing is, once this all becomes software based, the security and rules of using it are dictated by carriers, and this is the real problem for me. For instance, will the carrier allow me to use more than one device with the sim? What limits will they impose between IMEI and IMSI? What I really wanted is to have a single number for 3 different devices simultaneously... the smartphone, a local phone that is there for backup and to replace the landline, and a smartwatch that I wear while out and about, particularly when running and I don't want to take anything else with me. But I imagine carriers won't allow me to do this, because they'd rather force you to pay for extra accounts to have that sort of functionality. I also wonder how much of a different this would make for security and privacy. Not that having a physical chip with info is that different from the info being embedded into the device's own hardware, but a degree of separation is there. In any case, with iSims being a thing, I guess it's just the way things are gonna go.
Except when you're writing their names like you're doing. Its Xs and Xr. If apple didn't want to confuse people they should have written it properly, we're not Romans.
@@ekoprasetiyo True And that's one of the reason why GSM beat CDMA And now the American bringing the CDMA weakness to GSM still thinking that their idea always better.
It was a funny situation when my friend bought a phone, pulled SIM slot out and prepared to insert a SIM card there, but... he searched and searched for a card in the phone box, but no card at all. He found just some paper with a number. It's your new SIM card, I told him. Are you kidding? No, I didn't. He called CS, told the number and made the phone working.
If you need to pay for that service then pick another carrier, that should be free (at least for a certain number of transfers within a fixed time period). The problem is your carrier, not eSIM itself.
Let's exchange a hardware key for a QR code, what can go wrong? Especially now that confirmation codes for bank transactions and alike are sent via SMS. I see absolutely zero benefits for the customer, just a loss of control. If my provider ever forces me to use eSIM I'm switching providers.
If you have an iPhone you've had this ability for years. Apple can also remotely lock the phone making it really hard to unlock, decreasing it's resale value a lot.
So, we don't have iSIM yet and neither do we know if it will be popular or if it will replace eSIM. In other words it is just a proposed specification that isn't currently being used.
I think Apple chose esim because of the high volume of stolen phones from stores and shipments. Not so much on customers! You rarely see where there is a rush on stolen Android phones! I will continue to purchase sim vs only esim! Thanks Professor 🎓
I have S23 ultra, it can't use 2 active eSIM, only one active at a time> "The Galaxy S23 Series offers a Dual SIM slot and also has eSIM support. User may use up to two physical SIMs or 1 eSIM & 1 physical SIM at the same time. The Galaxy S23 Series lets you store multiple eSIM profiles, but only one can be used at a time">
I use two sims, a physical sim for work and personal esim on iPhone 13. The reason for not having two esims is that on carrier demand that I need to visit them when i need change my phone, which is not cool.
The Pixel 2 and Pixel 2XL were the first phones to use embedded SIM (eSIM) technology. However, the eSIM feature for the 2 and 2 XL devices is only available to Fi subscribers in the USA. It needs to be activated in the USA but is enabled for global usage through Google’s partner networks.
You didn’t cover what happens if you lose your sim enabled phone / how to move your sim from old phone to new phone. Bit of a glaring gap but otherwise informative, thanks
I heard that Esims are burdens on battery( they suck battery more then the normal Sim, some has reported that it takes like 5-7% of battery) , so is it true ?
totally not true. doesn't make any sense it's just an id to connect to a network. reading the info from an esim chip or physical sim chip doesn't matter.
Interesting I am in the USA using Verizon and I don’t see any IMSI only a ICCID or a EID or a CSN number except of the IMEI I thought the IMSI is used for the global travel sims that have multiple carriers so every carrier have its own IMSI even you only have one ICCID
eSIMs are yet another nightmare for privacy. Since you can't remove them from the phone and phones with removable batteries are a thing of the past, the only way you can be sure you're not being tracked is to leave the phone at home
I tried getting an esim from o2 and that didn't work well. They sent 3 different bar codes for the esim and on 3 occasions none of the bar codes worked. So not a good experience.
I'm concerned about privacy since I'm not Hunter Biden and don't have the FBI on my side to cover my a$$. Will multiple esims get leaked to the carrier? When traveling to certain countries/satellites (China, Hong Kong, Macao, etc) I worry about privacy as the minute I go through the airport I'm being tracked facially...
We were warned about these esim cards. Now carriers can limit your access to whatever they choose and worse it can be used for tracking purposes. They'll say that it's in case you lose your device etc but it's more about tracking you, especially through the ever-controversial 5G. No, I'm not one of those conspiracy theorists but I can read and understand what I read, especially in the small print that everybody ignores. Another interesting point is ... who remembers back in the day when we could only use our devices on certain networks or with certain providers? There's a good chance that's coming back. Just watch.
Interesting comment. Genuine question, how does an e-sim increase the tracking abilities of the phone company compared to a normal SIM. Also, how does 5G increase the tracking abilities compared to 4G?
I'm a regular person. I bought a regular budget smart phone. It works great. I have looked after it and so it still works great. It will still probably work great in 5 years time if I continue to look after it. But will the world have 'moved on' such that it no longer works great? Probably. Technological progress does not benefit everybody.
Bad review, sound like a marketing material, without mentioning the bad part of eSIM. Which is when transferring the number to new phone is *NOT AS EASY AS* using the old SIM.
No it won't. Now if you loose the fiscal note that's printed in a technology with ink that disappears in 2 years you won't be able to transfer the phone to anyone. Great, buy a new phone, very ESG
Others have commented similar sentiments. What made it bitter? The phone company? The service charges? Your replacement/spare phone didn't support eSIM?
I do not like this. I would prefer my SIM to be device independent. There are all sorts of downsides to this. For instance what happens if I go abroad and temporarily want a local sim card? Having it tied to the device will create a lot of bother.
🤔 Going abroad and needing a new SIM is one of the advantages of eSIM. You just pickup a QR code in the new country and activate it. Your old profiles aren't deleted and you can switch back and forth as much as you like.
Now I remember what eSIM is. Don’t use it, just don’t. It is locked into one phone meaning it cannot be used in another. Saving you from having to watch a long unnecessary tirade about what it is.

If you need to pay for that service then pick another carrier, that should be free (at least for a certain number of transfers within a fixed time period). The problem is your carrier, not eSIM itself.
@garyexplains great, now if you loose your fiscal note you can thrash your phone.
Now, they're coming out with iSIM which moves the SIM into the processor itself.
Jill's another level of integration
Why even need to identify where it resides? Maybe just sSIM where it's secretely somewhere in the phone no one knows...
Let's exchange a hardware key for a QR code, what can go wrong? Especially now that confirmation codes for bank transactions and alike are sent via SMS.
I see absolutely zero benefits for the customer, just a loss of control. If my provider ever forces me to use eSIM I'm switching providers.
Yep.
I have an eSim on my Galaxy watch now it is fine. I had trouble finding a TelCo company that used eSIM that was over a year ago. I live in Thailand.
if you have iphone, esim is good in case you lost your phone, since no simcard can be removed, so your phone can always be tracked....
If you have an iPhone you've had this ability for years. Apple can also remotely lock the phone making it really hard to unlock, decreasing it's resale value a lot.
Now we have iSIM
Which phones support iSim?
@@GaryExplains Not right now but in the very near future, flagship models will.
So, we don't have iSIM yet and neither do we know if it will be popular or if it will replace eSIM. In other words it is just a proposed specification that isn't currently being used.
@@GaryExplains Yes!! But it looks promising.
Interesting, what advantages does it give? Why is it promising? Is it just a way for Qualcomm to try and monopolize SIM technology?
How’s e sims with locked iPhone 12
i have the S22+ and it has esim.
I think Apple chose esim because of the high volume of stolen phones from stores and shipments. Not so much on customers! You rarely see where there is a rush on stolen Android phones! I will continue to purchase sim vs only esim! Thanks Professor 🎓
S22+ is actually eSIM compatible.
I have S23 ultra, it can't use 2 active eSIM, only one active at a time>
"The Galaxy S23 Series offers a Dual SIM slot and also has eSIM support. User may use up to two physical SIMs or 1 eSIM & 1 physical SIM at the same time. The Galaxy S23 Series lets you store multiple eSIM profiles, but only one can be used at a time">
Thanks for the info 👍
So if the phone gets destroyed, can you rescue an eSim from it?
It will probably work like a physical sim card. Where they deactivate the number on the old simcard and register it with the new simcard.
There are will be pros and cons. One in case of phone is destroy it need replace. Or transfer to new phone.
I use dual physical sim. More secure.
I just bought the Samsung Galaxy a54, and it has the e-sim.
I use two sims, a physical sim for work and personal esim on iPhone 13. The reason for not having two esims is that on carrier demand that I need to visit them when i need change my phone, which is not cool.
The Pixel 2 had an esim.
The Pixel 2 and Pixel 2XL were the first phones to use embedded SIM (eSIM) technology. However, the eSIM feature for the 2 and 2 XL devices is only available to Fi subscribers in the USA. It needs to be activated in the USA but is enabled for global usage through Google’s partner networks.
You didn’t cover what happens if you lose your sim enabled phone / how to move your sim from old phone to new phone. Bit of a glaring gap but otherwise informative, thanks
I heard that Esims are burdens on battery( they suck battery more then the normal Sim, some has reported that it takes like 5-7% of battery) , so is it true ?
Not true, both eSim and physical sim have negligible effect on battery life.
totally not true. doesn't make any sense it's just an id to connect to a network. reading the info from an esim chip or physical sim chip doesn't matter.
MACs can be changed or faked, same for IMEI...
Interesting I am in the USA using Verizon and I don’t see any IMSI only a ICCID or a EID or a CSN number except of the IMEI
I thought the IMSI is used for the global travel sims that have multiple carriers so every carrier have its own IMSI even you only have one ICCID
I don't really like the idea of an eSim, I always carry a spare sim to pop into my phone, should I need a change whenever I wish. 😉
I thought e stood for electronic for some reason 😂
Because the traditional SIM card runs on steam? 🤔🤣
@@GaryExplains exactly 🤣 facepalm moment.
It could well be to do with us in general being used to an "e" being used to indicate it's electric
@@Walker998 as it is in eMail, eBay or eCigarette.
Hey, this video is two hours old! I thought you claim to cover new technology! What is the history channel??
Eh?
eSIMs are yet another nightmare for privacy. Since you can't remove them from the phone and phones with removable batteries are a thing of the past, the only way you can be sure you're not being tracked is to leave the phone at home
Sounds like you need a specific phone if you’re so worried about government stalking on your anime waifu pics.
@@YaretziaGarcia fairphone
In India it's a boon
I tried getting an esim from o2 and that didn't work well.
They sent 3 different bar codes for the esim and on 3 occasions none of the bar codes worked. So not a good experience.
I'm concerned about privacy since I'm not Hunter Biden and don't have the FBI on my side to cover my a$$. Will multiple esims get leaked to the carrier? When traveling to certain countries/satellites (China, Hong Kong, Macao, etc) I worry about privacy as the minute I go through the airport I'm being tracked facially...
We were warned about these esim cards. Now carriers can limit your access to whatever they choose and worse it can be used for tracking purposes. They'll say that it's in case you lose your device etc but it's more about tracking you, especially through the ever-controversial 5G. No, I'm not one of those conspiracy theorists but I can read and understand what I read, especially in the small print that everybody ignores. Another interesting point is ... who remembers back in the day when we could only use our devices on certain networks or with certain providers? There's a good chance that's coming back. Just watch.
Interesting comment. Genuine question, how does an e-sim increase the tracking abilities of the phone company compared to a normal SIM. Also, how does 5G increase the tracking abilities compared to 4G?
I'm a regular person. I bought a regular budget smart phone. It works great. I have looked after it and so it still works great. It will still probably work great in 5 years time if I continue to look after it. But will the world have 'moved on' such that it no longer works great? Probably. Technological progress does not benefit everybody.
Bonus is that as the sim cannot be taken out, you do not need a sim pin. You can just disable it.
Bad review, sound like a marketing material, without mentioning the bad part of eSIM.
Which is when transferring the number to new phone is *NOT AS EASY AS* using the old SIM.
Review? I thought I was explaining what an eSIM was. Also, if your carrier makes that difficult then don't use an eSIM or change carrier.
eSIM will be something of the past in a few years. iSIM will replace it, which will save even more space and increase security
No it won't. Now if you loose the fiscal note that's printed in a technology with ink that disappears in 2 years you won't be able to transfer the phone to anyone. Great, buy a new phone, very ESG
eSIMs are a bit of a nightmare with a broken phone. Bitter experience, so never again.
Others have commented similar sentiments. What made it bitter? The phone company? The service charges? Your replacement/spare phone didn't support eSIM?
I do not like this. I would prefer my SIM to be device independent. There are all sorts of downsides to this. For instance what happens if I go abroad and temporarily want a local sim card? Having it tied to the device will create a lot of bother.
🤔 Going abroad and needing a new SIM is one of the advantages of eSIM. You just pickup a QR code in the new country and activate it. Your old profiles aren't deleted and you can switch back and forth as much as you like.
Where do you find a QR code
just take a extra mobile phone with you when travelling, buy a Sim when you arrive out there
Sounds like a hackers/cloners dream.
Couldn't be easier. One UK SIM and my French eSIM. Effortless.
Now I remember what eSIM is. Don’t use it, just don’t. It is locked into one phone meaning it cannot be used in another. Saving you from having to watch a long unnecessary tirade about what it is.
came for help, got a PowerPoint
And? Was the information lacking?
SIM
He didn't explain why Apple want to push eSims but the networks don't want them.
But iPhone 14 models purchased in the United States don't have a physical SIM tray and support only eSIM. So how did the networks not let it?
Yea naw they are easier to hack 🤣😅
Huh?
Eh?
