Dear All,
I'm using Libelium's Hilo/Sagem-GPRS-shield more than one year with increasing succes (SMS,Calls,HTTP/TCP). But now I get a new problem which I'm not able to solve by myself.
The Hilo-module get not attached to an other GSM operator when I moved to foreign countries, although the operator selection is set to automatic mode (via AT+COPS=0).
I think this problem is not related to the SIM-card, because if I put the SIM-card in my cell phone, roaming works fine.
Dose anybody has a similar problem and is able to help me?
Thanks, S.
