Will the mobile be compatible with my country's network?

A key part of any mobile phone specification is its operating frequency bands. The supported frequency bands determine whether a certain handset is compatible with a certain network carrier.

Following is detail of mobile phone's operating frequency bands:

2G networks include GSM 850/900/1800/1900, and importantly, not all mobiles can support all frequency bands.  And  2G network supports making calls, sending text messages and using GPRS/EDGE mobile data connection.

3G networks incude UMTS(HSDPA) 850/900/1700/1900/2100 and importantly, not all mobiles can support all frequency bands.  And  3G network supports making video calls and using a high-speed 3G data connection.

After understanding the above basic information, it is easy to decide whether the phone can work with your network. Here's the point:

1. First find out what's 2G and 3G operating frequency bands that the mobile phone supports. (you can find it on the product description)

2.Contact your service provider to check what operating frequency bands that they use or check it HERE.

3. If the mobile's supported operating frequency bands include all the frequency bands that your network carrier uses, and it works. Otherwise, it can't work.


To make you have a better idea about this, here are some examples:

Example 1:

Nokia 1280 : it only supports 2G network(GSM 900 / 1800). In Hong Kong and Australia, all the network carriers use GSM 900 or GSM 1800. So, the nokia 1280 can work on Hong Kong and Australia 2G network. But of course, the 3G network can not work, as nokia 1280 can not support 3G. 

But Canada and United States's network carriers use GSM 850 or GSM 1900, which means that the nokia 1280 can not work on Canada and United states's 2G network.


Example 2:

HTC Sensation: it supports 2G network : GSM 850 / 900 / 1800 / 1900 and 3G network : HSDPA 900 / 2100

As it supports all 2G GSM networks, the phone can work on all 2G networks all over the world. And for 3G network, if a United states network carrier uses HSDPA 850, the phone can not work with that network carrier's 3G network, but if a United states network carrier uses HSDPA 2100, the phone can work with that network carrier's 3G network.
