Hi! My boyfriend and I couldn't make calls to each other since last night. We took turns dialing each other's number but to no avail. The would just always give us a tone indicating that the number is busy. I also tried calling him using another number but the result is the same. SMS would also fail many time before it is delivered. On previous months we have difficulty contacting each other too, but after many attempts the call would connect, but this time it won't. We both have full signal bars and both can use our data. Can you tell us why is this happening and help us? He is in Lapu-Lapu City and I am in Cavite.
