Search by LTE band
Right now, there is only a check box in the phone finder for LTE. The problem is, LTE has different bands. It would be nice if we could expand the LTE search option to select different bands the phone must have.
Example, I want a phone that works on T-Mobile USA (LTE Band 4) and western Europe (LTE Band 7, mostly). If the phone can't do both, I don't want it.
I do go Munich to Prague sometimes and just leave my German Vodafone SIM in. I wouldn't have to do that if all the T-Mobiles would offer free international roaming to each other.
