How to achieve faster 3G data network on android galaxy note

I am using 3G on a heavily 4G nation (singapore) where my Internet connection sucks until I did the following.

1. Go to settings
2. On 'device' tab click on 'more network'
3. Click on 'mobile networks'
4. Click on 'network mode'
5. Select the 'wcdma/GSM (auto connect)

If you have already selected the mode and still feel laggy on your Internet connection, please contact your Internet service provider.

If the above help you, remember to share with your friends. Cheers!
