Questions and Answers

Which model will work on US T-Mobile bands? The R202 shows it supports bands 2,4,5, & 12 -- all of which T-Mobile supports. The R203 drops band 5. T-Mobile also supports 66 and 71, so I imagine it's maybe a coverage issue only? Or is there more to it than that?

Hi there, we can see from datasheet **** that the r202 not only supports LTE bands 2,4,5,12, but also support UMTS bands 850, 1900. R203 only supports LTE bands 2,4,12. thanks.
