My mom's S6 phone recently started dropping calls after she answers. She doesn't have any apps running and uses it strictly as a phone, doesn't use the internet.
I'm sorry to hear that you're experiencing dropped calls. I rely on my service too and I'll be happy to get this fixed for you. Can you tell me when this first started? What's your city name and can you provide me with the nearest intersection, so I can investigate the area? Are any other users experiencing the same issues as you?
