Let us all why the phone is not compatible.
There are two reasons to explain this. The first is that all service providers in the world is not running on the same frequencies and encoding services. Therefore, if you look to the United Kingdom, your phone may not match the frequency of the service.

The second point is a bit complicated. To mobile phones to work in Great Britain from the United States, service providers in the United Kingdom, and vice versa, there must be an international clearing agreement with one or more service providers in other countries. The inter-clearing agreement is a commercial transaction between the provider of the two countries, leading to your mobile phone roaming. In some cases, roaming on your phone, you need to suppliers in the United States. If so, then you roaming, and ga the country. Such an arrangement, the international roaming. The same situation is also the national roaming. Therefore you need a telephone, the operation of all three-band service on the word, the phone is a quad-band functionality.

However, you should consider the GSM business is very limited in the United States. This way you can return to it later. No, there is no solution. Make your voice heard, you need to compare two phones, one of the major networks in the United States and the second, the GSM roaming services.
