Oh no, I'm sorry to hear about the issues you're experiencing with your service. I know how I depend on my phone for just about everything. I'm more than happy to take a deeper look into this to see if we can pinpoint what's going on, this way it can be resolved quickly.
May I have your zip code, so we can review the network in your location? When did this issue start? Is the issue with a specific person or all that you speak to over the phone?
Having a working device at all times is crucial, Pixiedean61. We want to ensure you can always hear your callers and they can hear you. Do you remember any changes around the time this began (i.e. software update, app update)?
