is it true that 9930 can be used with gsm sim card ?? if yes then isn't it better than the 990 coz it can have 2 different services active on it where as 9900 can just have one.
say if i buy a 9930 unlocked and get it registered with a Verizon or sprint and also put a sim card in it of t-mobile or at&t, what will happen both the services will work or just one or do i get to choose??
Yes, the 9930 can be used with a gsm card. However I don't think it has the necessary 3g band to work with at&t and tmobile. It should work on 2g though.
