if network LED doesn't blink what to do.And only DC-PMR led is on in SIM 900a
Please how u check if gsm is connected to Arduino uno using hardware serial port
Hello. So I am using an external power supply of 5V 2A and the GSM can register to a network without issues, but when I try to send messages through Arduino, no messages are sent. Why is this happening?
Can you try this tutorial on sending SMS

Also, check the phone number. Maybe it needs a country code extension
Mine Owen dosn't blinking. I dont no what to do
Hello, i have a similar PCB with SIM900, when on, the module sends RDY +CFUN: 1 +CPIN: READY +PACSP: 1 Call Ready (9600 bauds), whei send to the SIM900 la comman "AT", the module responds - AT -, dont receive - OK - . Its damage the pin TX of the PCB with SIM900? what can i do to test and verify if a need to buy another new brand module?
To be honest, it's hard to verify a working module from one that doesn't. One of your best bet would be to liaise with your vendor. If that is not possible, I suggest you buy another working module and test to compare the output.
how many recepients thus the gsm module be able sending messages?
I have the same type of gsm module here in Zambia 🇿🇲. The problem is that its blinking continously every after a second and that means its not connecting to the network. What should I do to solve this problem?. Thank you in advance
Well, can start checking the basics like money balance, data and signal reception. If that doesn't work, you might want to contact your local SIM Card provider to check if there is any restrictions.
Hi, I have a question what is the problem when it says in the serial monitor sms sent successfully but then I didn't receive a message. And it also prompt an error message of AT cmgf

Does this work with European SIM cards too?
That would be best answered by your telecommunication(telco) provider. Some telco may have restrictions
I like your video
Check the power and try varying the location. If it still doesn't fix the issue, it could be telco restrictions
same problem. from Philippines.
Hello! can I ask if your gsm sim 900 worked?
@@andreacimacio2836 has yours worked?
Hello sir , you told TX to RX and RX to TX of arduino but why you connected it to 7 and 8 pins?
Hi, this is just the first video. Please watch Part2 to understand better.

Can i use it to conect to internet and connect in that way to my own app?
Yes, it should be possible for GSM to connect to internet.
Can i know how much V and mAh for 18650 battery to power up the GSM?
Each of those batteries in the video are 3.8v and since it's connect to Arduino's DC jack it will draw current according to the circuit's need. This GSM would generally around 2A or less to work.

What are the rating of dc power supply
5V 2A
J' aime sa . Que dieu vous bénisse
Hey Please do a tutorial of that Sim900a With Fire detector 3pins😔😔I really really need it.

Are you going to be building a web page to use GSM to interface?
For now, only using it to send text messages. Maybe in the future, i will explore on its https requests and etc
