@mitJ@in 256 Report post Posted October 7, 2011 No, for EVDO B, First network needs to be EVDO B Secondly a compatible device should be there.(MTS are locked and cant be used with BSNL SIm) Share this post Link to post Share on other sites
me_saket 73 Report post Posted October 7, 2011 if u get unloked REV B, than BSNL EVDO SIM/RUIM will work. But wont give any EXTRA Speed. it will like upgrading modem at benifit of ZERO. bcoz It will work on exiting REV A network only, just upgrading device to REV B wont help u.
