Sim card

[Woo128]

Hi I just got a new sim card and when people try to ring me it says the number has not been recognised and no one can ring me but they are able to text my number and I can ring out on my number does anyone know why thanks

@Woo128 Why did you get a new sim? Have you lost your previous sim or was it damaged? See if this link helps: https://community.o2.co.uk/t5/How-to-Guides/Sim-Swap-a-mini-guide-2017-update/ba-p/1060675

It can take up to 24 hours for all services to come online completely.
Try restarting your phone and if it’s still not working correctly give customer service a call this morning at 8.00am

In that case call customer service as advised above but also keep rebooting your phone

Though if it isn't working correctly after rebooting the phone, then ring CS as shown above... or pop to your local O2 store

With some form of identification or they wont assist.

Actually they will assist if you are an existing customer as they will pull up your details

I have never been asked for ID in my local O2 shop. It may be area dependent but they brought all my details up on the PC. Swapped the sim there and then. Walked out with it working,
