 Carrier Compatibility (USA / Global)

The Oppo F31 Pro+ supports GSM / HSPA / LTE and 5G (SA/NSA) network technologies with dual Nano‑SIM capability. An unlocked unit can work on GSM‑based carriers such as T‑Mobile and AT&T in the USA if the phone’s supported LTE and 5G bands align with the carrier’s frequency requirements (the device includes common global bands like 1, 3, 5, 8, 28, 38, 40, 41, 77, 78 for 5G). Advanced network features such as VoLTE and full 5G NR support depend on regional firmware and carrier certification — check band compatibility with your carrier before purchase. For global use, its broad 5G/LTE support makes it compatible with carriers in Asia, Europe, Africa, the Middle East, and other regions when unlocked and bands match local requirements.
