Call going blank then coming back

[Drew83]

Hi swapped from Virgin to O2 and now every call I get or make has periods in all of them where I can't hear the person and they can't hear me for 5/10 seconds and then the call comes back I think I need a new SIM card most likely

Pop into your local O2 store with photo ID 
Call 202 from your O2 mobile or 0344 809 0202, 0800 902 0217 or 0800 032 1402
When it comes to the reason you are calling, stay silent for 15 seconds and you will be taken to the keypad options.
Press 2 for Everything Else
Press 5 for More Options
Press 7 for Anything Else which will put you though to someone.
Say 'Upgrade', 'Lost/Stolen', or 'Fraud' if the suggestion above doesn't get you through.
Best time to call is 8 am.
You can also reach O2 via social media:
Facebook (https://o2uk.co/O2CFB), Twitter (https://o2uk.co/O2CTW), or Instagram (https://o2uk.co/O2CIG)

Hi Got a message from somebody but can't find it saying something about a setting clear call I think 🤔

That message would not have its origins in this forum as we don't know who you are ! 

Have you contacted Customer Services about your problem ; did they leave you a voicemail maybe ?
