Just got the E530 and for some reason it has suddenly come up with area codes on the display. They wernt there before, how do I get rid of them? Also, there are some funny messages in my inbox with the area codes in the message. I never received them as text messages and it says they are from '200'. What are they? One last thing (for now), why is it suddenly saving my received text messages to the sim card. I dont remember asking it to do this. Sorry for all the Q's. Please dont say RTFM. :-)
I'm not sure why your phone is saving your texts to your sim but to answer your other questions, you are receiving cell broadcasts. you need to go into your message set-up menu and switch receive cell broadcast to no/off. This should get rid of your unwanted messages aswell.
