T-Mobile uses Band 4 / AWS / 1700 for LTE and WCDMA in my area. The differences between the two are noted here (and many other places) – ChinaMobile lacks Band 4 and Band 17 for WCDMA and LTE. However, the chip inside the OPO can have baseband filtering at a software level if I correctly interpret the available documentation. I am lucky enough have access to both versions – ChinaMobile and International – in the USA on T-Mobile Prepaid LTE.īased on my research, the hardware appears to be identical between the variants, which would make the most sense from a manufacturing standpoint. I have been making some progress on the OnePlus One.
