So you pretty much have to try out each plan on each service to know if it's going to work.
I don't have a PinePhone, but I've done the "bring your own device" thing on discount MVNOs about a dozen times over the years. So I've run into these "gotchas" a lot. Sometimes it's possible to find the actual technical restrictions of a given plan, sometimes it is not.
These appear to be the bands the PinePhone will work on:
Are there current software restrictions on this?Code:LTE: B1, B2, B3, B4, B5, B7, B8, B12, B13, B18, B19, B20, B25, B26, B28, B38, B39, B40, B41
WCDMA: B1, B2, B4, B5, B6, B8, B19
GSM: 850, 900, 1800, 1900 (MHz)
At least you can mostly eliminate some plans just knowing this.
I am not sure I fully understand what you are saying.
In your example, AT&T has different plans, but they should all use the same network, or not?
I thought the phone networks were dependent on the carrier (Verizon, AT&T, etc).
Are you saying that knowing the carrier is not enough to know if it is going to work or not?
Same question but from another angle. Can AT&T (or any other carrier) change network type depending on the plan?
Can you please clarify on this?
