I have the arduino uno and arduino GSM shield. I used the sendsms example code under GSM.
I uploaded the code to the uno. My code however stops at "SMS messages sender". So in the serial
monitor I only see "SMS messages sender" and then my code stops running. I think the shield is unable
connect to the mobile carrier? I live in South Africa and am using an MTN sim card. Been struggling with
problem for a while now. If anyone could help me/ shed some light on the problem, that would be deeply
I tried the pin management example code under GSM. I found that for three different sim cards(different
carrier networks), i got "PIN & PUK locked. Use PIN2/PUK2 in a mobile phone." in the serial monitor.
I live in South Africa...anyone encounter this problem or have solutions?
Put the card in a phone, unlock it and remove the need for pincode.
Ckeck that SIM-boads LED blinks every 3 sec (connected to network)
(blink every .8 sec means "not connected")
Thanks guys...i checked the link. Have been experiencing similar results. Will implement what was said on the other post and i let you know.
