Lost my sim for my tablet

[1Caitlen1]

I’ve lost the sim for my tablet, as my tablet it connected to my mobile phone number, this means I can’t access my account because of the security, it’s asking to send a code to the number connected with the sim I have no access to

@1Caitlen1 - report your SIM lost, how to do that here: Guide: Lost or Stolen O2 Device? - How to Report it - O2 will block the lost SIM and send you a replacement.
