I have a feeling s3 is the most compatible but I really like the r2 model
Can anyone shine into this matter? Please
Can someone please help?
Welcome to our Support Community! Just as a heads up, bumping posts usually makes it take longer for us Community Managers to respond. From checking out both models of phones you listed, here are the types of network connections that the phones would be compatible with:
R2: Band 2, Band 5, and Band 12
R3: Band 2, Band 4, Band 5, Band 12, possibly Band 66
If you'd like more info on what those technologies mean, you can check this out: T-Mobile network . Let me know if you have any other questions!
