I ported my phone number from Vodafone to O2 about 2 weeks ago. Since then ALL incoming calls that I receive are being displayed as No Caller ID.
I have no way of knowing who is calling me, and if I miss a call I cannot call them back etc.
O2 have allegedly troubleshot but continually fail to resolve the lack of CLI (Caller Line Identification).
I believe I have tried everything with O2 helpdesk several times over, which included a complete replacement of the physical SIM, the move to an eSIM and back again, Network Settings reset on the handset, the move of the SIM from my Apple iPhone to a brand new Samsung Android handset to eliminate the potential of the issue being on the Apple ID account or linked the the iPhone and iOS. I have also seen some forum threads that mention disabling 4G and also some threads telling O2 to add a Bolt On for CLI Presentation to be added, but when doing the latter the O2 helpdesk say they know nothing of this Bolt-On and are therefore unable to add it.
The issue is ridiculous and frustrating. I can make outgoing calls and my number will display for the person receiving the call, but as mentioned above – when anybody calls me (whether from a landline, mobile or various networks – or even if I do or don’t have their number saved as one of my contacts) I never get a number displaying – I only get No Caller ID.
Please give me some ideas of what to do, or what to instruct O2 to do next.
Big thanks
