Three months ago, I upgraded to Blkberry Curve 8530 and I really like this phone. During the 3 months, I've had to replace the phone 3 times because I was having trouble hearing the person on the other end except when I turn on the speakerphone. The Sparks Verizon store representative was very friendly and tried to troubleshoot but was unsuccessful and gave me a new replacement. Each time I received a new phone, I would change the hearing aid mode to t-coil to accomodate my hearing aid. My 3rd phone (only had for 1 week) now has the same problem of not being able to hear the person on the other end, I was able to have a phone conversation this morning at 7am and at 10am I could not hear the other person. I troubleshooted and found that the Telecoil stopped working by turning off the Telecoil. Is there a solution to fixing the Telecoil?
