This has happened to me last week with EE and it’s absolutely stupid AND RIDICULOUS that they just disconnect your existing service. I rely on my phone for business and can’t be without having an active connection.
I went down to a EE shop and they said the only way they can give me a new SIM card is if I upgrade my contract because I didn’t have any ID with me. Plus I was offered a better deal for the same price so I went with it and got myself a new SIM card for the phone to keep working.
I received the eSim that evening and scanned the code for it to NOT work. Called back EE again and was told that my account switched from eSim to normal sim again. I mean what the hell?!
So they couldn't give you just a replacement SIM because you didn't have ID, but they could upgrade your contract and give you a new SIM without any ID????
