Lockdown mode allows one to optionally disable 2g, maybe it is also the default there. One can turn 2g back on in said mode if desired.

As to 3g, it is largely switched off here, and I understand most of the rest of the world is also disabling it.

However it does not remove images from messages, it just disables certain automatic helpers - e.g. link previews etc.

One can still send photos, etc without any issue.
