Intermittently unable to make calls, calls are received but other person hears my voicemail

Hi all, 

 

hoping someone can help me, I’ve been having an intermittent issue with my O2 for 2 weeks now.

 

At different times of the day, both on WiFi, 4G and full mobile signal strength, when I try and make a call, it doesn’t ring at all and get “call failed” or “call cancelled”, when someone calls me, my phone does ring, but they either will or won’t be able to hear me, and it goes through to voicemail even if I pick up, with me getting a “you missed a call from me” text. 

I’ve called O2 customer services and they mentioned something about a 360 migration failing, why was I not informed that I’d be being migrated to a different system which would cause me to lose services? And why has this issue occurred several times over 2 weeks, and no O2 system caught it until I complained about it specifically. 

Can the 360 migration cause these issues, or have I yet again been led down a rabbit hole by O2 CS?

@DavidAllan 

Can't see what 360 has to do with it at all.

Check for network issues Guide: How can I sort out my network issues?

We love O2 sending me down another rabbit hole. The issue does resolve after rebooting my phone, or toggling airplane mode. Looks like I need to ring O2 again

Nope, it’s intermittent over the past 2 weeks. Apple have ran diagnostics on the iPhone and said it’s all fine, I’ll have to see what O2 come with this time.

Possibly a sim card problem

Call into your nearest O2 store with photo ID

They will change it for you free of charge
