So I had 3G and EDGE working, incoming calls, SMS, everything, working now on Mexico's TELCEL network.

Only problem was that I go on the subway every day, and then the phone would lose signal and display the "Your SIM played a tone" message, and the only way to get it back was to activate it again, so WiFi was needed for that. But I always had the 3G enabled.

Now... I trusted it was all working so I changed to a postpaid plan and now I can't even activate the phone since it's always searching for signal and it won't recognize the R-sim even. It also has a 256Kb SIM now, 4G/LTE.

Do you think it's a SIM thing? should I go back to 128Kb cut SIM, or even to a prepaid plan?

No working sim 4g , only 3g telcel
