2G, 3G still is in phone.

Hi.

Why that old not used 2G and 3G is still in phone?

Thanks for answers.

i think question is poorly worded, you probably mean "why technical gsm/2g and umts/3g capability is in pinephone and pp pro even many networks has shutdown those networks?".

pinephone and pro uses eg25-g modem chip, which has gsm, umts and lte functionality. and lte in eg25-g support volte as well. eg25-g is intended for iot devices more than ordinary phones. but in other hand, many iot devices rely on lte and nr5g networks. software can disable those features, but capability is still there.

hint: use lte only or 4g only. some cases you have to use at commands.
