Calls cutting out

[Sleigh]

Hi calls are cutting out or not being heard on my hand set, text is fine and audio can play through my handset. Are there any restrictions on my SIM

@Sleigh This is not O2. This is a customer community. You need to speak to customer service.
Call 202 from your mobile or 0344 809 0202, 0800 902 0217 (Payment Management) 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 (now X) (https://o2uk.co/O2CTW), or Instagram (https://o2uk.co/O2CIG)

Alternatively, call into an O2 store, if you have one nearby, and do a sim swap, as it may just be a faulty sim.

You could try a borrowed or PAYG SIM in your handset and see if you have the same problems ; also try your SIM in a different 'phone. This just might narrow down the issue prior to your calling Customer Services.
