Using an older unlocked GSM Blackberry in BKK for data ?

[imperial]

Hi ,

Is anyone using an older GSM unlocked Blackberry for data in BKK ?

 

I have an old 7520 Blackberry at home that I use on NEXTEL/Boost (not GSM) in the USA for checking email etc with OPera Mini, it has a full keyboard which makes it nice to type , its twice as wide as a regular cell phone.

it does NOT go thru Blackberrys servers ,

 

I am just wondering if I can do the same thing with the same style GSM blackberry ,

I would just get a Sim card for the blackberry and NOT use it as a phone.

 

Anyone ?

 

thanks Dave
