If the phone is not 3 or 4 band gsm it will not work the US, the EU and Asia all use 2 bands each. Look up the documentation that came with the phone to find out the radio frequencies supported by the device, and look up here for info on which frequencies are supported in different countries

Hope this will help

    Frequencies cannot be changed, The only way out of it is to buy a model designed for the US of A. The frequencies are governed by hardware soldered to the mainboard of the phone. It is a similar concept to the difference in the FM radio band between the US and Europe using 88-108Mhz while japan uses 85-105.

    If you can make and receive calls on it you should not have an issue with bands, If this is the case, refer to your network customer support and ask them for specific access point info such as requirered IP address, username and password as it is unlikely that there is an automatic setup program as the handset was manufactured out of the country.

The phone used to connect to the internet with wifi and 3G. Now it only works with 3G. It sees the wifi network, but says that it cannot connect to this network. It does this on every network I have tried...

If your looking to use only wifi at times. You need to go into the setting and shut off the 3g data and have only the wifi option active.

Cellular data over rules wifi at all times. That's their little trick at getting you to use up all your data plan.

Here's the steps:

1. Go to Settings
2. Scroll to Network
3. Cellular Data - slid to OFF
4. Tap General on the top left
5. Tap Settings on the top left
6. Scroll up to Wifi and tap
7. Make sure Wifi is on and finding networks.
(Note: Only networks without the lock are public networks unless you know the pass code to log on)
8. Make sure Ask To Join Networks is to OFF
9. Click the arrow blue arrow on the network you connect too and make sure HTTP Proxy is set to OFF
10. You should Connect just fine

To reverse this and go back to Cellular data. Follow instructions 1 - 5 except you wanna turn Cellular Data back On.

My computer ideapad lenova,i am not able to connect to internet,one IT specialist told me that my slot for inserting cable is bad what to do i am now in china Ghanzhou city

Do you mean the slot?
Is it the cable that goes into the LAN port?
If so you can use a LAN PCMCIA card and connect the LAN cable into this card.
You can connect to the Internet using a USB 3G adapter which uses the cell phone network with a cell phone provider.

Will not find connection

Then the phone is not compatible with the band (Frequency) used in the united states or with the SIM-cards they use in there.
You should contact an USA operator and tell him the problem: that you can use it in China and in Europe and the phone doesn't find the network in the USA.
