i googled PRL to understand what that is. sounds like some geeks try to circumvent VM/Sprints service to roam Verizon's. didn't see date of post and a warning was given, along with a mention that VM/Sprint would probably block settings eventually anyway. course i wouldn't mess with anything outside legalities...so i called VM explaining problem...again. Few days ago, tech told me to go outside...and that worked. so my husband was considering getting a house antenna. but then i made call to him cell-to-cell (cell to land not a prob) from shopping center down the road and msg left was garbled. he was with me but had cell off. so, again, i'm disturbed that i'll be stranded somewhere unable to reach people on cells. VM tech today listened to my grievance, checked the area and said reception good. had me turn off, take out and reinsert battery and turn back on. still no indication of a signal, or one mark at best. so she said it was software problem and is sending me a new phone. i have my doubts that will resolve prob, but i'll try anything. this signal issue does seem to be draining the battery. i noticed earlier after talking for less than two hrs with my mom (connecting to her landline) that battery was half drained, so called VM at that time, and they sent me new battery. haven't even tried it though cuz the garbled call issue took over. tmi? sorry.
