AnswerYES !!! GSM Phones, CDMA Phones will work in India
As long as the Blackberry phone you will be using on the GSM technology of Telus is 3G capable, then it is possible.
Yes they do.
GSM phones will only work in Trinidad and Tobago if they have a SIM card available to use with it, especially for international phone calls.

No it can not.
Unlocked phones are GSM phones that will work with any GSM carrier. A GSM phone works on AT& T, T-mobil and any other system that is GSM compatible. Most inetrnational cariers are GSM.
GSM is a cellular network and mobile phones connect to it by finding other GSM phone in the area. These phones are spread across 212 countries and territories and work whereever there is another GSM phone in the vicinity. The coverage area of each phone is also dependent on the cell size.
There are two types of cell phone networks, GSM and CDMA. As long as the network you are trying to move your unlocked phone to is compatible then yes it will work. In most cases a GSM phone will not work on a CDMA network and vise versa, however, some careers (such as Verizon) have support signals for GSM phones. There is no support for CDMA phones on a GSM network at this time. So for overall versatility, GSM phones are better.
Telus and Fido are both brilliant phones so either would be great.
