A few weeks ago I had a problem getting a successful GPRS session established with a Wavecom modem with T-Mobile in Germany.

I know that GPRS was enabled on the SIM card (as it worked correctly when inserted into a SE T68i), but I could only get the Wavecom modem working correctly by using either a Vodafone NZ or a Vodafone Germany (D2) SIM card.

I know that I had the APN correct, but despite trying many different options, I could never get an IP address assigned to my WindowsCE device. I know that I was attaching to the GPRS network correctly (as I monitored the traffic), but getting an IP address was impossible.

It appeared that T-Mobile was not allowing the modem to work on their GPRS network.
Is this possible? Do providers only allow certain types of devices?
Or is there another explanation?

Any suggestions would be appreciated.

Kind Regards,

Are you sure the SIM card wasn't a 3G one, with different voltage?

I suspect it wasn't (although I can't be 100% sure) because it worked correctly in a couple of phones (T68i for example). Good thought though - I must add that to my list of potential causes of problems!
