Question

I am on a PAYG plan and I am unable to make calls or use data roaming. I get a message that I have "no credit available" even though I have a positive balance.

I understand that one must top up their PAYG account every 120 days even iff you haven’t used up your credit, so I added £5 and it seemed to fix the problem, but than after a few days it started again, saying I have “no credit available” even though my balance is more than £11. Also, the problem is intermittent. My phone will work one minute, and then not work the next minute. I did some research on this problem with ChatGPT, and it indicated that the problem has to do with the fact that I’m using a pre-2021 SIM card which cannot reliably register for VoLTE, even though my phone supports VoLTE. Topping up briefly kick-started my phone, but it never sticks. Older PAYG SIMs were never fully compatiible with the new VoLTE porvisioning system, expecially on iPhones (mine is an iPhone 11, and I signed up with iD in Aug 2020). The simple fix is to replace the SIM. I tried contacting an iD agent but I can’t get past the ChatBot. It keeps asking for my Customer Service PIN, which I don’t have and have no idea how to get. There’s no such thing when I log into my iD account. So my question is: how do I convey this information to an iD agent so they can send me a new SIM? Thanks.

Hi ​@Beal ,

 

Thank you for your message. It sounds like your pre-2021 SIM is causing intermittent service and VoLTE issues, and replacing the SIM should resolve this.

To get a replacement SIM:

-Contact iD Mobile Customer Support via live chat or phone (0800 00 343 11).

-Explain that your old SIM is not fully compatible with VoLTE and causes intermittent service.

-Provide your phone model (iPhone 11) and account details so the agent can verify your account.
 

The agent will then arrange a replacement SIM, which should fix the issue.

I tried calling 0800 00 343 11 and I can’t get through as the number is “not recognised”.

Hi ​@Beal ,

 

Thank you for letting us know. I’m sorry about the confusion and inconvenience caused.
 

Please try contacting iD Mobile using one of the following options instead:

-From an iD Mobile phone: dial 7777

-From another network or a landline: call 0333 003 7777

-Live chat: via the iD Mobile app or website
 

These are the correct contact options and should connect you to our support team.

I called 7777 and you cannot get through to a live agent. You just get refered to online agents, which, as I’ve already explained, I am unable to do without a Customer Service PIN. Very frustrating! I think I’ll just change my provider. How do I get a refund of my current balance?

I finally was able to get through to chat with a live agent and the problem has been resolved as they are sending me a new SIM. However, I forgot to ask: will I get a new phone number? If yes, I will need to port the SIM to my current number. Also, can you advise how to transfer all my phone’s data to the new SIM without losing anything? Thanks.
