Dear iD Mobile Community 

I recently switched my mobile service from O2 to iD Mobile. Since the transition, I have been experiencing an issue where I am not able to see the caller ID on any incoming calls. All calls I receive are displayed as "Unknown" or "No Caller ID", regardless of who is calling.

I have already taken the following steps to troubleshoot the issue:

1. Checked with multiple contacts (friends and family) — None of them have enabled any setting to withhold their caller ID.

2. Verified with multiple devices — I’ve tested the SIM in another phone and still face the same issue.

3. Phone settings reviewed — Caller ID settings on my phone are correctly configured to allow incoming caller information.

It’s clear the problem began immediately after switching to iD Mobile, and KEEP MY NUMBER. The ID Sim was working perfectly before Keep My Number. I have changed the physical sim on advise of ID Mobile Team. ID Technical Team is investigating but its 3rd month I am bearing with all calls as UNKNOWN.

MOBILE SHARP AQUOS R.6

PHYSICAL SIM.

Any Insights are highly appreciated. Thank you for your support.

Hi ​@Mian Kashif 

We’re sorry to hear this.

 

Which device are you using?

 

Is this for every single contact on your device or some contacts?

Hi ​@Anika A.

I appreciate your time. I am using Sharp Aquos R.6, It was working fine with O2 and ID Mobile, after Keep my number the problem started and now its three months, I am bearing all the incoming calls as UNKNOWN. There is not even a single call in this time frame with Caller ID i.e caller's phone number. There is no way to call back the missed calls and there is no way to see which calls are important to attend and reject. I am helpless and frustrated.

Which device are you using?

SHARP AQUOS R6

Is this for every single contact on your device or some contacts?

Every Single Contact.

Many Thanks for the understanding.

Thank you for confirming. 

 

Unfortunately the handset you are using is not an iD Mobile approved device.

Are you able to test the SIM in another handset?

Hi ​@Mian Kashif 

 

Thank you for confirming!

 

Is the VoLTE option enabled on your device? 

 

Does the Google account used with your device have the correct mobile number?

There are no settings relating to inbound caller ID, just outbound (e.g. withholding your number) so it won’t be a setting issue.

My advice would be to put your sim inside a different device, preferably one on the iD Mobile supported list. You've done that, and you've tried replacing the SIM.

I'm thinking maybe something went wrong with the port (split port) but I've never come across such an issue before, so I can't say for sure. Either way, iD Mobile will have to raise a ticket with THREE and have them look at your account.

Thanks ​@Anika A for asking.

YES, VOLTE Option is enabled on the device.

YES, Google account used with device has the exact number, which is the same number used since 6months.

Hi ​@WelshPaul.

I appreciate your time, please.

You are absolutely Right, Its really hard to make them understand because initially they were guiding me stupid things i.e Install Truecaller, How to Hide ID, How to Block Unknown calls.

The ticket has already been raised and 3 SLA Of 48 hours has been passed and its 4th SLA of 48 hours in which 24 hours has been passed but still facing the same issue.

Thanks for the reply ​@Tyler C. I have already made it clear proactively on the chat that if they are unable to resolve the issue in the current month i.e Current Billing Month, this would be the last month for me with ID Mobile and moreover I also needs compensation for the services which are not fully offered and especially the time factor.

Hey there ​@Mian Kashif, no problem. They’ll work that out with you once the resolution is in place, or if we cannot resolve.

 

Thanks,
