Q: Does the JACS TD191-B work in Thailand?

JACS TD191-B in Thailand: good on 2 networks (AIS, True), not usable on 1. Band-by-band gaps per network, with official sources.

Partly: 2 good, 1 no.

How to read this: coverage layers are bands below 1 GHz; they carry signal into rural areas and buildings. Missing one may still work in cities but suffer outdoors far away and indoors. Capacity layers affect speed and busy-hour experience.
