Unusable

[Daniel267]

For the past 3 weeks I have not been able to make calls without the audio dropping out, mobile data is dreadful at the best of times, 5g or 4g nothing makes a difference.. been through all the usual checks with my iPhone, but on WiFi FaceTime audio works perfectly so pretty sure it isn’t a hardware think, anyone else begrudgingly paying a phone bill for a service I’m not being provided

What are "all the usual checks" you've been through - can you be more specific?

Does the audio drop-out momentarily, or completely stop mid-call and never return? Is this in a specific location, or a more general issue?
