 Carrier Compatibility (USA / Global)

The vivo Y31 Pro supports 2G/3G/4G LTE and 5G (SA/NSA Sub‑6) network technologies. An unlocked unit can typically work on GSM‑based carriers such as T‑Mobile and AT&T in the USA if the phone’s supported LTE/5G bands match the carrier’s network requirements. Advanced features like VoLTE and full 5G NR support depend on regional firmware and carrier certification — always verify band compatibility with your carrier before purchase. For global use, the phone’s broad LTE/5G coverage makes it compatible with carriers across Asia, Europe, Africa, the Middle East, and other regions when unlocked and bands align.
