Nokia 6620 ( 1900 MHz ) to ( 900 MHz ) - GSM-Forum

Lovelysupercat · 06-06-2005, 10:52

Dear brothers,
About Nokia 6620,
how can I check 1900 MHz or 1800 MHz or 900 MHz?

My country is using 900 MHz.

This 6620 did not show network signal.

Its start up logo is AT&T.
IMEI:353755000155855
Version: V 2.14.1
28-06-04
NHL-12

If this is 1900 or 1800 MHz,
how can I change to 900 MHz?

Thanks you very much.

Yours

Dear brother,
I think, when you flash 6620 to 6600 and if phone is dead,
you can flash again to 6620.
Because I flash SonyEricsson T610 to T630.
Phone was dead.
And I flash again to T610 and it is OK.
But for me,
problem for 6620 is no spear part and I don't know exactly which one need to
change.
I want to compare the SM of 6620 with 6600.
If it may be possible, I want to try to change to 900 MHz.
When you get idea, please may I know.

Yours

One of my friend who live in Thailand said that 6620 is not same platform with 6600.
Then we cannot change 6620 to 6600.

Is this true?

Thanks
