I purchased an SMT5600 from Cingular and then unlocked it to use internationally. Now that I'm in the Middle East and have inserted the local company's SIM card, I'm getting very poor signal strength (or none at all in some places). I would love to know if there's anything I can do to boost signal strength. The crazy thing is that I'll be standing next to a coworker who has a cheap phone and is getting 4 bars and my expensive phone is still searching for a signal.
I called Audiovox's tech support and they were absolutely no help. The guy thought it might be the phone but I bought 2 at the same time and they both have the same problem. Tech guy then said that since my phone was made for Cingular then it just might not work where I'm at.
I'm wondering whether one of these internal antenna boosters would help. Anybody try them?
