Hi ​@CazKins,

I'm sorry to hear this, and I can understand why you're concerned.

The message you've received doesn't look like a standard notification that we'd expect customers to receive from iD Mobile regarding a SIM replacement request. As you don't recognise the request and didn't ask for a SIM change, it's important to get this checked as soon as possible.

Please contact our Live Chat team immediately so they can review the account, check whether any SIM swap request has been submitted, and take any necessary action to protect the account. If required, they can also arrange a replacement SIM.

You can contact them here: https://www.idmobile.co.uk/live-chat

In the meantime, if you still have access to your service, keep an eye out for any loss of signal, unexpected verification messages, or account changes you didn't request.

Regards,

Gemma M
