*3001#12345#* > then press "call"
A small number will show up on the "upper-right" corner instad of "bars"
-55~-65 >>> Excellent signal strength good, no problem
-85~-95 >>> Ok to receive data and voice calls.
-100 and below... (-103)call drops
I hope this little infomration will help :)
2. "-95"... i suggest you could turn off "3G' function , use Edge (2G)... in this way... at least you won't miss incoming calls... and still can receive-in push mails... it's balancing act.
3. The best signal strength i ever had was "-55".... where underneath a "base station".
3. I hope people here can BANG Chung-Hwa telecom HARDER, keep demanding them to improve the signal strength anf quality.
4. By the way, iPhone 3Gs's receiption indicator (the bars) is cheating... and cannot reflect the real time receiption status...
