I got a pay monthly SIM card for my son to use in an old phone.
The phone is unlocked and works with SIM cards from O2 and Tesco Mobile - the only other ones I have to check it with.
When I insert the iD SIM, I get 2 bars or more of signal.
The APN info is greyed out but matches the info given on the iD website.
I cannot make or receive calls “unable to connect, insert a valid SIM”
About phone/SIM status says network and phone number “unknown”.
After all this, I tried online activation of the SIM card (even though I was told this wasn’t needed). Result, “Sorry, we're experiencing some issues processing your request. Please get in touch so we can get it sorted.”
I spent 30 mins plus on the online chat but this got nowhere then I was cut off.
