No, range of the phone is GSM 900/ 1800. GSM range in the US is 850/ 1900.
Yes it will as long as it is GSM and it is unlocked
AnswerYES !!! GSM Phones, CDMA Phones will work in India
No you cannot. AT&T uses a GSM network and Boost uses iDEN and the two are not even remotely compatible. The Boost SIM card can be used for international roaming but it will not work with GSM networks in the US. It will not work either way, a Boost SIM will not work in a GSM device and a GSM SIM will not work in a Boost device.
In North America, GSM operates on the primary mobile communication bands---850 MHz and 1900 MHz. GSM-1900 is the primary band used in urban areas with 850 as a backup, and GSM-850 being the primary rural band.

Yes they do.
a phone with these two facility can work in GSM with sim card and can work without sim card in cdma mode
The short answer is no. Boost's newer iDEN phones do use a SIM card that can be used in GSM devices for international roaming but they will not work in GSM devices in the US. Most iDEN phones are not compatible with GSM networks, and GSM phones are not compatible with iDEN networks.
