I have a doubt, shouldn't the 5V of the Arduino provide a current lower than 1A?

[@deepanjalimishraa]

im using a 9vdc and the network led doesnt stop blinking also it shows no netwprk while calling

[@virajmurkute520]

Thank a lot bro❤❤❤ its really work

[@user-ek6rl5xj3v]

¡FELICIDADES. MUCHAS GRACIAS!

Hi can you explain the other pins usage in gsm 900a board and can I connect a microphone and speaker to gsm900A?

[@aliulhasan1490]

I need help in connecting gsm 900a and neo 6m please let me know

[@adebunmihabeeb4769]

HI, is there a way i can use sim900 to send SMS using my subscription/megabyte instead of using my airtym balance.

[@subidadhikari]

Hello bro. The red light is blinking every seconds. What might be the reason?

[@jnumzeid4924]

my pins 7 and 8 has already been plugged.. to what other pin can i plugged for the sim 900a module.

[@alibayat504]

yes you can change myserial(7,8) to every pins that are free.

[@loggerino7331]

I powered the GSM module through the 5V pin of the UNO but the GSM still cannot register to any network. What is causing this issue?

[@muhdikhwan2958]

Did you find the issue

[@loggerino7331]

@@muhdikhwan2958 The UNO's 5V pin cannot power the GSM, you need an external power supply to supply 2A of current.

Hi do you have any Tutorial of this sim900a with Fire Sensor, that will also send sms to phone when detecting a Fire?

[@technolabslk5914]

I do not have any tutorial for that. But you can do it. Its very simple

[@EL90291]

Awful music….but great information, thank you for sharing

[@vishnuvish598]

hai, i want to ask, is the connection and configuration for connecting NodeMCU 8266 with GSM 900A is the same? and can u make a video on that?

[@technolabslk5914]

I will try to make a video for that.

[@sakthikumaran9718]

my gsm module is receiving msg and not sending msg or calling. i used an external power supply of 5v2A.

[@nektarioskoumantakis4987]

Can you give a code sample that if a digital or analog pin of Arduino board is HIGH to send an SMS ?

[@technolabslk5914]

Sure. I will edit the description with code example

[@SAAJITH-NM]

i didn't receive message using your code could you solve it?

[@otaku-san4719]

Did you get it?

[@otaku-san4719]

I'm also facing the same issue

[@SAAJITH-NM]

No dute

[@karthiktech7574]

bro which sim dou you use 2g 3g 4g in your sim900a please tell me bro ?

[@luego]

is the sim900a only limited to 2g/3g? i have the same problem too. it keeps returning +CPIN: READY RDY +CFUN 1 on my serial monitor. im using 4g/5g sim

[@technolabslk5914]

I used 3g a 3g sim bro

[@karthiktech7574]

@@technolabslk5914 ok

[@faizan4742]

@@technolabslk5914 Bro does it work with 4g sim

[@mishealunegbu1766]

I tried your code it did not work

[@MALLUTHAMIZHA]

Hi, I have done the connections and uploaded the code, serial monitor shown s~send sms, but sms is not received, gsm not sending sms, what would be the error? Please help me

[@esakkiappanthevar3320]

Same bro ,want the solution

[@jumbo999614]

@@esakkiappanthevar3320 I found out in the internet that you need 5V 5A adapter for gsm to work.
Do not use 5v from arduino. I just bought gsm module but need to get the adapter too.
Let me if it works with the adapter.

[@technolabslk5914]

Do not use arduino board 5v. you have to use separate power supply which can give 5v and 2a

[@jumbo999614]

@@technolabslk5914 ่I finally got it to work. But it took like a minute or two to send message. Do you know how to increase the speed? Also the serial port gives some warning about over current. I use 5v 2a adapter. That's weird.

[@jumbo999614]

@PaTing I live in Thailand. The simcard that you're going to get is most likely be different than mine if you're not in Thailand.
I use sim that supports 2g and 3g.

[@wccomedy6907]

Gsm 900a is some time work some time not .
What is problem

[@technolabslk5914]

which power supply did you use?

[@technolabslk5914]

@PaTing does that gsm module connect to the gsm network?

[@jumbo999614]

@PaTing The sim card thing is bad. I already gave up on using it. Don't waste your time with it.

[@carloscandido4801]

Why you had to put that music.....

[@technolabslk5914]

I like it. Thats why i used it
