Lost network connection after my number was ported

[Meconopsis]

I have recently joined O2. On Tuesday (6/12) I received the SIM (Tarif: O2 Sim Only Unlimited mins 12M 4GB). I put it into my phone and it worked perfectly. With the PAC code from my previous provider I called O2 and the transfer of my number was scheduled for the following day, Wednesday (7/12). In the afternoon I lost connection with my old provider and online in 'my O2' my old number was now the one associated with my SIM. I had been told by O2 to change the settings of my iPhone, so I put my number into the 'phone/my number / settings. I turned my phone off and back on again. But it did not find a network. Now, more than 24 hours later this is still the case. Help, please!

Reset your network settings.

Other things to try (assuming you have reset the network settings @Meconopsis 😞

• check the SIM is correctly in the phone
• give the SIM a wipe with a non-static cloth
• try the SIM in another phone to see if that works (if yes, indicates an issue with your phone)
• try another SIM in your phone (if that works it indicates an issue with your SIM)
• contact o2 customer services to see if they can help - call 202 or message on social media (links below)
