Hi, I inherited an old phone which was fine with 2 old providers. Phone is not locked to other providers. I followed step by step instructions to change settings frm yr site. I choose option to save apn settings and they disappear. Have done few times 😞 no luck 48 appears on list of network operators with 2 other providers but cannot tick them as no option. Tried resetting apns before I carried out instructions again but still no luck. Switched on data roaming in case that would help but nothing. This is really bad.. Have just spent 20e and now no mms no phone no internet SOS can you help me! Recd messages with settings however they wud nt save/open/install and disappeared after I clicked them.
