The Nokia 6630 and the 6680 are great phones but have a few problems if you buy a Three network badged version.
Most networks customise their phones to offer specific menu features in a way they like but most of them also withhold
certian menu features.
On most modern Nokia's there should be a network selection menu whereby you can search for new networks and select
which band the phone will operate on ie GSM or WCDMA.
Please note that from now on when I refer to WCDMA I am referring to the 3G network operated by Three and likewise
GSM will refer to the backup network used by Three which is O2.
Three have 'hidden' this menu and if you follow this path you will see what I mean;
1:menu
2:tools
3:settings
4:network
5:network mode
when you arrive at this point you will see that the only network mode available is 'Dual mode' but it is already preselected
and note it is over halfway down the screen. This is because there should be two other options available - GSM and WCDMA.
What I have available is a very small program (around 100k) which you upload and install on to your 6630/6680. The file is
in the .sis format and can be uploaded by Bluetooth, sent by email and downloaded as an attachment or installed using
Nokia PC Suite. When you run the program you get loads of other info about which cell you are using and signal strength
etc etc but we are only interested in one option which allows you to force the protocol between GSM and WCDMA.
You can now select between three options.
1:Dual mode - this is the default and will select between GSM and WCDMA and is dependent on signal/network availability with
a preference being given to WCDMA.
2:GSM - selecting this option will force the phone to use GSM at all times.
3:WCDMA - using this option will force the phone to use WCDMA at all timesWhich menu is best?
.If you are using Three and suffer from many dropped calls due to being located in an area with poor Three coverage then you
can select the GSM mode. If you have purchased a Three badged phone and had it unlocked by Three and wish to use another
SIM card you will still be forced to use a WCDMA (3G) network unless you select GSM mode as unlocking will not enable this
hidden menu.
.If you wish to force the phone for some reason to stay on WCDMA (3G) then you can select WCDMA and the phone will not then
handover to a GSM network.

DISCLAIMER:
Use this at your own risk, if you do not have any knowledge of GSM protocol and advanced engineering menus, you could do
serious damage to your beloved 6630 / 6680 so PLEASE make sure you only select the specific menu options as stated.
It is very easy if you follow the instructions. Please also note that should your phone need to visit a repair centrer for
any reason I would strongly advise removing this program first. If you install it onto your memory card you won't have
any problems - just take the card out before taking it for repair, thats how I use it on my 6630. This program in itself
if used correctly will not invalidate your warranty but the existance of it on your phone could be a reason for the repair
agent to claim you have edited settings you should not have.
