Topic: problem with sim card (Read 9374 times) previous topic - next topic


Hi, I have some problems too, with different SIM cards from Italian networks.
I tried to use, for two times, a new SIM from WIND company, see the attached picture, and the shield did not work ("not connected"). Furthermore the SIM, after these tests, did not work any more (on my cell phone I read: SIM refused).
Then I tried two different SIM, from TIM company and an old one from WIND, that work quite well.
I suspect that the new micro-SIM from WIND does not match well in the Shield, although the plastic shape is the same.



it's only power supply problem...give it 12V DC and everything will work just fine!!!
The only problem is when u buy that damn thing noone tells u that...
just give 12v to yr arduino...
