Incoming calls 'not ringing' for incoming caller

[Pete007]

Hi,

As the title says, intermittently for the last 6 months or so when somecone calls me normally the call would connect, start ringing (on both ends) and then you answer. 

The phone rings for me, but not for the caller - i.e. its as if i pick up the phone without it ringing (but for me it rings). 

o2 are aware of the problem and apparently im not the only customer, just wondering how widespread it is? Hoping to highlight the issue on here, its been happening for months and its a bit dissapointing o2 have not managed to sort.

If you have anything with an esim on your account, it's been a known issue from the start. 

No sign of a fix from O2 yet though.

Yes, i have an EE eSim connected as a backup/private number on an iPhone 11 Pro Max along with my physical o2 SIM.

That's the issue then.
The fix is dependent on O2 I'm afraid.

Ok thanks for your help.
