Hi, I was wondering if someone could help. The issue started a couple of weeks ago where calls might drop randomly, but for the last week I've been unable to make or receive calls.
My phone can display a full signal, but if I attempt to make a call, either the signal just drops and the network becomes "unavailable", or nothing happens--no ring/call tone. From what family and friends tell me when I contact them through something such as Facebook messenger--on their end, it will either ring for a few seconds and go straight to voice mail, or tell them that I'm on another line.
This happens both inside of my home, out in the open.
I've tried removing and reinstalling the SIM, resetting network settings on my handset, and even going far as a factory reset of the phone itself.
I can, however, receive texts (thank goodness because of verification codes) and use internet data. I am PAYG. My phone is a little outdated, a Samsung Galaxy S7, but it does have 4G/LTE--and I'm mentioning this because I'm aware 3G is being phased out. I very recently topped up and did get a text confirming it--as well as addons appearing on my account dashboard.
I hope I'm providing enough information here to troubleshoot.
