Carrier Compatibility (USA / Global)

USA: The Tecno Spark 40C supports 2G, 3G, and 4G LTE networks (no 5G). An unlocked unit can work on GSM‑based U.S. carriers such as T‑Mobile and AT&T if the phone’s supported LTE bands align with the carrier’s frequencies. VoLTE or carrier‑specific features may not be guaranteed without local certification, so check supported bands with your carrier before purchasing.

Global: The phone is compatible with broad GSM, 3G, and LTE bands common in many regions across Asia, Europe, Africa, and the Middle East, making it suitable for use on many carriers outside the U.S. as well. Always verify the exact supported bands of the specific model you plan to use for full network coverage.

It supports 2G/3G/4G connectivity globally and can work with unlocked GSM carriers, though advanced carrier features depend on band support and certification.
