I am sick and tired of not being able to use my cell phone at home. I can not make out going calls. I cannot receive calls. I am seriously thinking of going to another carrier and breaking my contract with AT&T
Are other users having the same issues at your home? If it's just you, I recommend trying a new SIM card. Unfortunately no mobile carrier can guarantee coverage everywhere, especially indoors. If it's actually a coverage issue, AT&T offers a device called Microcell, which uses your existing internet connection to provide you the coverage inside.
