4G LTE issues often come from a few repeat causes: weak indoor signal, wrong network mode, outdated SIM, APN misconfiguration, or temporary congestion. The fastest way to diagnose is to change one variable at a time.
Start with basics: toggle airplane mode, restart the phone, confirm data is on, and set preferred network type to LTE/4G auto. Then test outdoors or near a window to see if the issue is simply indoor attenuation.
If LTE still won’t appear, check SIM seating and try the SIM in another LTE-capable phone. If it works elsewhere, the issue is likely device settings or compatibility.
