I got a chinese SIM900a module but it can't connect to the network (I live in Europe). Is there a way to get it work on Europe mobile networks?

  • Find a provider that still supports GSM. I know that in the USA they are phasing out GSM. Could you tell us the provider you are currently trying to connect to, and in which country? – Gerben Jul 18 at 14:57

  • The SIM900A seems to be carrier locked, and will only work in Asia. It appears you can update the firmware to make it work, as described here allaboutcircuits.com/projects/how-to-flash-the-sim900a-module – Gerben Jul 20 at 10:08
