Hi ​@P1dda4 

Thank you so much for reaching out to us, so sorry that your App is not working.

Here is what you can do:

If you've recently received a replacement SIM, the iD Mobile app may ask you to add a mobile number if your account isn't fully linked yet.

First, make sure you've activated the replacement SIM, as replacement SIMs don't work until activation is completed. Once activated, your original mobile number should transfer over to the new SIM.

If the app is asking for a number and you don't know what to enter, please try entering the mobile number that was originally assigned to your iD Mobile account. If you're unsure of the number, our Live Chat team can verify it for you and help link your account.

If you haven't activated the replacement SIM yet, you can do so through the iD Mobile activation page. Replacement SIMs must be activated before they can be used.

As this is a public platform, I’m unable to assist with account-specific queries here for security reasons. However, our team will be more than happy to help you via live chat. Please use the following link to get in touch: https://www.idmobile.co.uk/live-chat. 

 
Once connected, simply explain your request and an advisor will assist you further.

Thank you for your understanding.

Regards, 

Zubair
