Does T-Mobile USA prepaid offer roaming for SMS? T-Mobile USA prepaid maps show that they do offer 2G voice roaming even for prepaid customers. It is also know that they supposedly offer no data roaming and no 3G roaming.
How does this affect telemetry? Do I get SMS roaming on AT&T with a tmo repaid sim? But will GPRS not work?
