I've just returned from Portugal and whilst there I managed to get my usual mobile internet services set up on my phone and used my data as normal.
However, since I've returned home I can't seem to get my 4G data to work.
Ive tried restarting my phone, checked my roaming settings etc. and I can't seem to get my data back to normal.
Any help or advice is appreciated. I'm using a Samsung Galaxy S10+
