Mobile Data Support

For lost / stolen or faulty SIM cards, the best way to get support is to contact O2 directly on 0800 090 1786. This service is available 24 hours.

You will need to quote the mobile number and username associated with the SIM.  These were provided to you via email when your SIM activation was confirmed. If you do not have this information then please log a ticket with us using the support form below and we will take the matter forward in business hours.
