The specs don't mention dual sims and it does have LTE. What is the RM model number for these and where can someone see the detailed specs.
Possibly related: someone posted about a 640 case for sale that mentioned it doesn't fit the T-Mobile 640. I don't know if that was a mistake or does the T-Mobile one have different dimensions or button size/location. Maybe like the 521s were slightly different than the 520s but this time only the RM was different and not the name.
