pethro · 04-11-2002, 20:24

Hi,
I have 3310 that dont have signal in 2 operators while the other 2 is fine (i try with 4 difrent kind of sim cards), when doing manual search, it only show up 2 operators (it should be 4). these 2 missing operators are gsm900, while the 1800 can work good.
what I have done:
Remove the Resistor --> same result
Flash/upgrade soft --> same result
Full flash --> same result
Use eepron tools 3.1 --> same result
Rehot Cooba, hagar, flash etc --> same result
Change PA --> same result!!!
please help....

guys, maybe your ant switch is not working properly. Try replacing it. If still not working replace PA.

@Hanukkah
What do you mean by ant switch? (antenna switch?)
I don't think is the antenna problem cause the phone can operate normally with some operators (full signal and clear when use to make a call), while the other got no network.
I already try to change the PA, result is the same.

Can we check it using net monitor? Can it show up there if there is any error?
