MVNOs will often push/favor a specific model phone because it is locked into the host carrier "preferred network" that gives that MVNO the best deal/rates.

MVNOs often restrict the list of BYOD devices they'll support to a smaller subset than the host networks. The acronym BYOD means " Bring Your Own Device", indicating that a customer can port a cellphone or other cellular device they already own to the MVNO, rather than having to buy/rent a new device from them (assuming it is compatible with the host network, has not been reported stolen, is not still locked into a contract, etc.). ones discontinued by the host networks), which can affect whether all technologies supported by the carrier network are usable by MVNO customers. However, many MVNOs tend to sell somewhat older phone models (e.g. Verizon-hosted MVNOs: 4G LTE / LTE Advanced, 5G NR.UScellular–hosted MVNOs: CDMA, 3G 1xRTT / EVDO, 4G LTE.T-Mobile-hosted MVNOs: 2G GSM / GPRS / EDGE, 4G LTE / LTE Advanced, 5G NR.

AT&T-hosted MVNOs: 4G LTE / LTE Advanced, 5G NR.In general, the types of phones and other devices supported by the MVNOs are in line with the technologies used by the underlying major and regional cellular network provider(s): 5 Defunct, merged, and acquired operators.3 International SIM voice and data service operators.
