How to Disable 3G in Galaxy S?

A big thank to everybody who responded to my Querry on how to Disable 3g in galaxy. When I went to Etisalt to cancell my connection due to this ridiculouse charges, I was told, when you are using wifi in any 3G phone, if the signal is weak, it will automatically switch over to 3G data download. This is the reason we get heafty bill. However, people in the telecom world say it is possible to disable by the telecom providers but ETISALAT is greedy and they milk you out. So all I did is to cancell my line and subsribed to Du Elite plan and its much better.





We work here in UAE and the telecommunication charges are one of the highest in the world. I am using the Galaxy for a month now and paid huge bill  of 400 US $ unnecessarily for Data Download though I never surfed the web through 3G. My telephone company says in 3G phones when you are using the Wifi if the signal strength is weak, the phone will attempt through 3G hence my charges are?
1. Could somebody tell me how to Disable 3G in Galaxy?  I saw this option in Iphone 3Gs ?

2. If Disable is possible will I be able to use the phone for Calls?

3. Does the GPS in builit, when active, use the 3G for programs such as Navigation and Google Maps?

I appreciate members could help me as I cannot sustain the charges from my telephone company and do not want to give up my Galaxy either?

Thanks

hey arowana, kabayan?

i believe that the 3g on a prepaid subscription with etisalat is off by default.

What you need to disable is the Use of packet data not the 3G. 3G is just connection type.
If your pocket data activated, your phone will download,refresh and update.To turn it off:

Settings--Wireless and network--Mobile networks--Use packet data

If you want to save battery life you can change the Network mode to GSM only. (on default it should be on GSM/WCDMA auto mode where WCDMA is 3G. When you are on GSM the phone works on lower frequency which means consumes less power, WCDMA (3G) is a faster network type--needs more power--less battery life. If you dont use your phone on mobile internet go back to GSM (if your network provider supports it)

Without pocket data you can still make phone calls.

Your phone with the built in GPS works a different way than the GPS what you can buy for your car. In that GPS you have the country map built in but in your phone you don't which means when you use your phone as a GPS navigator it needs to refresh and load the map -- it will need internet connection -- you will need to have your pocket data turned on or you need to connect to a wi-fi network to see your position on the map.
