In general, the types of phones and other devices supported by the MVNOs are in line with the technologies used by the Mobile Network Operator (MNO), the underlying cellular network provider. All major and regional MNOs use 4G LTE / LTE Advanced and 5G NR protocols (2G and 3G having been deprecated and shut down), with GSM technologies.
Four of the top five wireless providers have all standardized on 4G LTE and 5G NR as their wireless communication standards, whereas Boost Mobile uses only 5G NR.Of which, LTE has been deployed across their entire coverage area; however, the LTE bands used by each provider remain largely incompatible.

The pre-4G 3GPP Long Term Evolution (LTE) technology is often branded "4G – LTE", but the first LTE release does not fully comply with the IMT-Advanced requirements. LTE has a theoretical net bit rate capacity of up to 100 Mbit/s in the downlink and 50 Mbit/s in the uplink if a 20 MHz channel is used — and more if multiple-input multiple ...
