First thing you need to have is a 3G ready phone. No, not all handsets are 3G ready.

Let’s take Huawei G610 as an example. According to GSM Arena, its network specifications are as following:

1. 2G Network: GSM 900 / 1800 / 1900 – SIM 1 & SIM 2
2. 3G Network: HSDPA 900 / 2100 – SIM 1

So its apparent that Huawei G610 is 3G compatible and hence can be used for activating 3G services on the phone.

Activating 3G on Phone

Note: We are using this Android phone running Android 4.3 for this Tutorial.
Go to

1. Settings
2. click “More”
3. Now click on “Mobile Networks”
4. Now on next screen, click on “Network Mode”

Here you will have to select “WCDMA (preferred) / GSM. This will enable your handset to search for 3G networks as well.

You are all done now, and 3G services will be activated on your phone whenever they will be available.

If your network is providing 3G services in your area then your phone will automatically switch to 3G network, otherwise it will switch to GSM / 2G network in case 3G isn’t covered in any area.

You can also select “WCDMA Only” option to remain on 3G network only, however, this way when there will be no 3G service your signals will disappear and you won’t be able to make/receive calls. Hence it is preferred to use “WCDMA (proffered) / GSM” option only.
Once your phone is connected with 3G network, you can go to Settings->About Phone->Status to see “Mobile Network Type”, which in my case was HSPA.
