Left O2 at the end of July. ID mobile sent me a SIM card and I've not been able to use my phone since as it statesĀ "Invalid SIM card. Network locked SIM card inserted" on my device. It works in my husbands phone. So frustrating trying to speak to someone at ID Mobile and I just feel like returning back to O2. Feel like nobody is answering what's going on with this SIM card. Can anybody help?
