This is really ridiculous.. i got new sim from O2, I called their customer care to migrate my into my old number, it was not supportive call.. he not responded in friendly manner. I used their chat service many times, no quick response, that we can forget. But i have to share my details around 4 times to complete migration into old number. When i contacted them again to know status they asking me to share the details again. What should i do??? I don't want o2 any more, its not completed 14 days so I hope there will be no any contracts.. I can terminate it without any lose.. its their mistake not mine... I don't want to share any details again.. Their final response, Hello Ajin, thanks for messaging O2 and waiting whilst connecting to us. Apologies for the delay in response. I really appreciate your patience. Thank you for choosing O2 as your new network service provider. I'll take a look at your account and the Port in status Just to let you know, this isn't an instant service so you can carry on with your day, your phone will let you know when I’ve messaged you back - Think of this as a WhatsApp style messaging conversation! I've checked the previous conversation and see that see that the port in request was placed yesterday itself on 19/03/2023 and the port in has been scheduled for 21/03/2023 hence ideally your number should've Ported in by now however I see that the Port in is not completed yet. Please accept our apologies for any inconvenience this may have caused. Rest assured, I’ll be happy to place the request to transfer your number to O2. I need to share a few details regarding this request. If you need any clarification, please do let me know. You will receive two text messages: One text message will be sent once the port has been booked to confirm the date. This will followed by reminder text on the day of the Port-In. You should make sure you back up any contacts you have on your previous provider's SIM, as these won’t be accessible once the number has been transferred. You will lose service for a period on the Port-In day, as the transfer is being processed. The Port-In will be completed by 6pm. You should restart the handset with the new O2 SIM regularly, until service has been restored. Text/Picture messaging may not work immediately after the Port-In, however, it will be up and running within 24 hours of completion. You can check your remaining allowances by sending the word BALANCE to 21202. This service won’t work for the first month due to the number port, however, it will be up and running after the second bill. You'll need to be in the UK when your number switches. As you have taken a SIMO deal with us and if your handset is locked to your old service provider, please contact them to unlock your handset. Please restart your device to check the network. You may be required to try this a few times till services are restored. Let me quickly ask you a few details with regards to the transfer (Port-in) request. Could you please confirm the mobile number that you wish to keep? Please confirm the temporary O2 number that you wish to replace May I have the PAC (Port Authorisation Code)? (A PAC normally comprises of 3 letters and 6 numerical digits for example 'ABC123456'). May I know when did you receive this PAC from your previous service provider? Please confirm the SIM Serial number of your new O2 pay monthly SIM? (It will be mentioned on the flip side of the SIM). Will you be in the UK at the time of Port -In?
