Hello, I am having the same issue. I want to upgrade to SIM only, my contract is due in 1 week and I want a SIM only. I tried doing it through my app but I keep coming up with errors. I cannot call customer services as I am now living abroad but want to keep my number. Is there another way I can have this resolved and upgraded to sim only?

Hi ​@justynapajak ,

I understand the situation, especially as you’re living abroad and want to keep your number.

To upgrade to a SIM-only plan, this will need to be done by our Sales team. As you’re unable to call us, the good news is that this can be completed via Live Chat, so you don’t need to phone in.

Please use the link below to speak with our Sales team, who can process the SIM-only upgrade for you and help resolve the app error:

They’ll be able to access your account securely and get everything sorted for you.

Hello,

Thank you for reaching out to me. Unfortunately I am also unable to use the chat option via link or directly through your website as I receive the same error. How else can this be resolved?

thanks,

Hello iD Mobile Support Team,

I’m looking for assistance and clear guidance regarding keeping my mobile number after moving to a new SIM‑only plan.

My situation is as follows:

• I took out a 24‑month phone contract with iD Mobile in April 2024
• This contract is due to end around April 2026
• I am happy to remain with iD Mobile and therefore purchased an iD SIM‑only contract
• My intention is to replace my original SIM with the new SIM‑only plan, while keeping my existing phone number

However, I’m now unsure how to proceed safely without risking losing my number.

I’ve found conflicting information between the iD Mobile website, app, and community posts. Some guidance suggests numbers are only retained if the SIM‑only plan is taken as an upgrade via the existing account, whereas other information does not clearly explain what happens if a SIM‑only plan is purchased separately.

At this point, I would like iD Mobile to please:

1. Confirm whether it is possible to keep my existing number in my situation
2. Explain the correct process to move my current number onto the new SIM‑only contract
3. Advise what steps I should follow in the iD Mobile app or website to ensure my number is not lost
4. Let me know whether support can manually assist, if this cannot be done self‑service

I do not want to leave iD Mobile, and I simply want a seamless transition from my phone contract to SIM‑only while retaining my long‑standing number.

I would really appreciate a clear, official response so I can proceed safely.

Thank you in advance for your help.
