So what is that going to mean, exactly? Will the Thunderbolt have a SIM in it, meaning it might be useable on other CDMA networks worldwide, or is the SIM only to provide functionality for LTE?
Do you know what doesn't make sense though? On one of those hands-on videos there was no SIM in the TB and the lockscreen showed "no SIM, emergency calls only"..........
Makes me think they'll require an LTE plan (and SIM) to use the device (ie., no 3G only).
