That's because 2G networks are shutting down (together with 3G ones) and 4G/LTE ones are moved to lower, more efficient, frequencies previously taken by GSM.

Disabling 4G these days can often be counter productive for signal strength and battery life.

Actually, 3G will be shut down first because so much relies on 2G networks.

You can always have peace of mind with airplane mode or whole data disabled.

Huh! That never occurred to me, but it makes perfect sense.

Oh well. :/
