Two phones stand in the same spot. One joins the newer cellular generation the tower is offering. The other phone's radio does not support that generation and stays on the older service. Which limit explains the second phone?
Select an answer to reveal the explanation.
Short Explanation
The tower is offering a newer service, and this phone's radio cannot speak it. You are limited by the radio. A dead card, satellite location, and a payment tap do not pick the generation.
Full Explanation
Cellular generations are different radio services. A phone joins a generation its radio supports. The second phone stays on the older service because its radio does not support the newer one the tower is offering, while a phone that does support it joins from the same spot. A dead SIM would not leave the phone camped on the older service. GPS is location. It does not block a cellular generation. Near-field communication is a short tap. It does not choose the cellular generation. Exam caveat: the phone can still be limited by the plan after the radio is capable. This stem isolates the radio, because the other phone succeeds in the same spot. Operational check: confirm the second phone's specifications for the generation the tower offers before you replace the SIM.
