I recently upgraded from a Samsung Galaxy S4 Mini to a Samsung Galaxy A3. I received my new SIM and on my O2 account, my phone number appears to be the same but i cannot receive phone calls or texts.
Also, on my O2 account, it says i am using the S4 Mini but the tariff and device plan show the details of the Galaxy A3. Do i need to do something with either my old or new SIM? Any help?
