Hi @mcaglar thank you very it worked!
For some reason modem cannot switch to 3G mode, all it provides is EDGE type of connection.
Do you know what needs to be done so it will work in 3G / UMTS mode? I’m in the UK, my mobile provider is O2, I use APN settings.
I only worked with GPRS modems, I don’t know how to switch to 3G mode but if you read the documentation carefully I am sure that you can find the way.
By the way, are you sure that the 3G service is activated by the GSM operator? If the SIM card is M2M, it may not support/activated 3G service. First of all, you need to be sure that the SIM card services are activated.
And one more thing, as far as I know, your problem (EDGE/3G siwtch problem) is not related with GSM operator or APN settings.
I see. Yes, service is activated, I use this sim card with my laptop that has GOBI2000 Sierra Wireless modem and it works fine with 3G.
I found some references of Sierra Wireless Suite that is capable of configuring these modems, changing modes etc. but all links to that software is long gone due to that re-design.
