Phoning out , my transfered number showed on friends phone
Anyone calling me, “unknown number”

Timeline

Email about delayed switching 15th Aug - took my by surprise  as thought it was all done
Compensation arrived 16th Aug (before they knew how long it would take
Switch complete 18th aug

Still no luck with people calling me today

As part of troubleshooting  it was suggested i remove esim and reinstall .. But now i find that you cant reinstall esim.. as its seems its a 1 time only thing.. !!

Can anyone else me get my service up and running, and get my esim redelivered please

Hi

Esim, now resent, via Customer Service / Chat.. But still no ability to recieve calls. or recieve SMS

I am however able to recieve calls / txts from Other ID mobiles, but not other Mobile services.. So there is definately something wrong with my “Number port” perhaps called a “Split port” from what i read , where the routing from one network to another is not working correctly .. Will be taking this up with customer Service in the morning again, via the chat service..

Hi @mikerog25.

Thanks for the update. I’m sorry you’re still unable to receive calls or SMS from non‑ID numbers after the eSIM was resent. What you’re describing does sound like the number/port isn’t being fully recognised by the device yet.

Please try a network reset on your phone. This often helps the device re‑register the new number and network correctly.

If you’re using an iPhone:

Go to Settings.

Tap Phone.

Tap My Number.

Use the delete button to remove the old number.

Use the keypad to enter your new (ported) number.

Tap Save.

Go to Settings > Messages and turn iMessage OFF.

Go to Settings > General > Reset (or Transfer or Reset iPhone > Reset on newer iOS).

Tap Reset Network Settings.

Once the iPhone restarts, go back to Settings > Messages and turn iMessage ON.

This should help the phone recognise the new eSIM and verify the number on the network.

If you’re using an Android:

Open Settings.

Tap General management (or System on some devices).

Tap Reset.

Tap Reset network settings and confirm.

Restart your phone.

After the reset, please test calls and texts from a non‑ID mobile number. If the issue persists, do continue with your chat tomorrow; https://www.idmobile.co.uk/live-chat.

Thanks,

Thanks for suggestions , I've now had around 5 different interactions over live chat all seem to focus on my device being the issue , even though I can't receive phone and SMS from other ID mobile numbers, and also I borrowed a id SIM , and that works perfectly.

In my view all points to a routing issue .

I've even done a HLR query to find out on what my carrier is . That came back with O2. Not 3/ID.

All points to failed port of number and whatever decides my number is with ID is failing

But live chat insist I try physical SIM .. and tech support have no other options

2 week down now without phone SMS inbound ..

Will be looking for a deadlock letter soon to progress with ombudsman.

Grrrr

Hi @mikerog25,

I'm sorry to hear you're still experiencing this issue, especially after two weeks of troubleshooting and multiple Live Chat interactions.

I can understand why you're questioning whether this may be related to the number port rather than the handset, particularly given that:

You can make calls and send texts, but aren't receiving inbound calls and SMS.
Another iD Mobile SIM works correctly in your handset.
Your SIM appears to be the common factor.

That said, we'd still recommend trying the replacement SIM if this has been offered, as it remains one of the key troubleshooting steps available to rule out any SIM provisioning issues.

As the matter has already been escalated, we'd also ask that you wait for feedback from the Technical Team, as they'll be best placed to investigate any potential routing, provisioning or port-related issues on the account.

I appreciate this isn't the progress you were hoping for, and I'm sorry for the inconvenience and frustration this has caused. Hopefully the replacement SIM and ongoing technical investigation will help identify the root cause and get the issue resolved for you as soon as possible.
