O2 Network suddenly withholding my mobile number

[Kernow_Mark]

Hi All,

Bit of a strange one, and had no joy with reporting the issue via the O2 My Network App, so opening it up to a wider audience ..

I've got an iPhone 7, and have always had my Caller ID settings to present/show my phone number.

As of late, on at least 3 occasions, in 3 seperate areas (differents cell towers) the O2 network has decided to show my number as unavailable ? 

A bit annoying for me as most of my friends and relatives use a True Caller call-screening device, which will only accept inbound calls from numbers in it's whitelist.  Hence, whenn True Caller gets an inbound call that presents as Unavailable or Witheld it doesn't connect the call, but screens it (adding maybe 30 seconds, maybe more) to the call I'm making.  When you're in a hurry, it's a right pain in the proverbial.

So, O2 - what's going on ?  I've reported it via the My Network App, but no faults have been identified, but clearly there has been a problem.  Is it going to happen again ?  What are you doing about it ?

If there are network upgrades going on, then a helpful heads up would be great, otherwise me thinks you've problems with your network that you aren't admitting to

Hi @Kernow_Mark Have you checked your network coverage here https://status.o2.co.uk/ ?

Or there is a guide here on checking network problems https://community.o2.co.uk/t5/How-to-Guides/How-can-I-sort-out-my-network-issues/ba-p/1014088

Apart from that, as I don't have an iPhone I can't offer any other advice. Sorry

Hi @Kernow_Mark

Unfortunately we can't answer your questions that are directed towards O2.

All wecan advise is that you keep onto customer services or raise a complaint with them.

Resolver gets good results.

Hi Cleoriff ..

Yep, checked for local issues and network problems, nothing showing up 😠

@Kernow_Mark I’m not saying that this is a fix.

but try putting 1470 in front of the number before you dial it. .

so for example if you had a Mobil number of 071234 etc.  Put 1470071234 etc so the 1470 is in front of the dialled number.

this command should  force the number to be shown.

.also if possible. Try the SIM card in another mobile, and if possible obtain a new SIM card from a o2 shop, see if a replacement SIM card resolves the issue. 

I know now you have said that you have checked the mobile settings and it’s showing it will send your number when you make a call.  Question is, does it happen to every call you make? Or is it random.

Last question, does this happen only to friends with Trucaller?  If this is the case, the fault may be down to how Trucaller is interpriting the CLI from the network.  As Trucaller is a separate app, it could be causing a miss understanding of the inbound call.  Why now ask you friend to turn of true caller or disable it or even delete it and then you try to call again, always worth a try

Putting 1470 in front of the number allows the call to go through, presenting my Caller ID as expected.

It doesn't happen on every call, but on random calls - including to people who don't have TrueCaller on their landlines.  My call presents to them as Unavailable (not witheld) ...

If I get my wife to turn Truecaller off (on the landline) then my number is either presented to her (as expected) or on random occasions it will present as unavailable.

All software / firmware is upto date on my iphone.  Have also tried re-booting it, but it still happens on random calls.  Haven't tried a replacement sim card yet ... not convinced it's the sim card, but more of a local network issue.  As far as I can tell, there is no network maintenance ongoing either.

Likey it will just fix itself when they reboot something network side.

Just to check it isn't your phone, you can dial *#31#  to see if your phone is set to send or withold CLID next time you make a call. (CLID - Calling or Caller Line IDentity)

(if it helps, @Kernow_Mark - could be a mast change near you has not been configured to pass CLID in your area, but as someone else has said, all should revert to normal when the O2 side realise and reset/correct...)

@Kernow_Mark Very strange one in deed.  I would say it’s some sort of bug in he software like it’s been mentioned and hope it will get resolved soon.

glad the 1470;works. Not idea though.

do keep us informed if it does get resolved and if it was a software update etc.
