Problem with SIM card registration

Hello,

 

I have recently bought a new SIM card from ID. When I try to register it and enter the number from the card that I just opened, I receive a message saying that it is already registered and that I should use another number.

 

I also tried changing the number by entering the PAC code and all required data, but it still does not accept it.

 

Could you please help me solve this issue?

Thank you in advance.

 

Best regards,

Dawid Dudek

Hi ​@0dido01 ,
 

I’m really sorry to hear you’re having trouble registering your new SIM card. I completely understand how frustrating this can be.
Please try these quick steps:

-Double-check the SIM number and PAC code for any typos.
-Restart your device and reinsert the SIM.
-Update your device software and, if registering online, try a different browser or device.

If this doesn’t resolve the issue, we’d love to help further! You can reach us via Facebook or Instagram, Live Chat, Community, or email us at socialqueries@idmobile.co.uk with your query details. More guidance is also available on our website.

Hi,

 

I have a question regarding SIM registration.

Is it possible to have two SIM cards (two phone numbers) registered under the same email address with ID Mobile?

 

My wife bought a SIM card for our daughter and used the same email address that she already uses for her own ID Mobile SIM. I just want to make sure this won’t cause any issues or conflicts with registration or activation.

 

Thank you in advance for your help!

Hi — is there anyone who can help me step by step to transfer my old number to a new SIM and then activate the SIM on that number?

The new SIM is already inserted in my phone. I have the PAC code and can provide IMEI and account details. Please connect me to an agent who can guide me through the process.

Thank you,

Dawid
