Happened to me too. Then I realized my sim card was not securely locked. Also, 12v is too much. You need 5v with at least 2a. I use 5v 5a adapter and it works great.
i powered my gsm sim900 mini with 5V and I have inserted sim card that is registered so the problem is it can't pick network, I've tried to change its antenna but still the same
@@machosipolilane9827 what is your country? Please check your country is works with SIM900. Normally it is take about 2 min to connect. How do you know it did not connect?
Gsm module requires more than 1 amps of current which Arduino simply cannot supply, try using external power supply of 5v but at a higher current draw
I found on the internet that you need to 5v 5a adapter instead of getting power directly from arduino
U shoud use separate batttery

My 900a module only shows the power red light.. No signal indications.. When i give power through 12v adaptor

U can use wh battery
the same problem
where can i get the required voltage by using batteries
is there anyways of using batteries as its power supply
Is your module turning hot?
Nop
Remove the sim and see
It is voltage isure

කොහොමද හදාගත්තෙ...? ඔය Module එකම මටත් තියෙනව. Power දෙන්නෙ 5V 2A adapter එකකින්. මගේ Connection LED එක 3 second intervals වලින් blink වෙනව ඒත් Serial commands වලට response නෑ...

Lesotho, to check the connectivity I just buzz the sim card inside it , the problem is on the GSM because I've used the very same gsm before.
