The guys over at CrackBerry answered the question previous BlackBerry owners forgot to ask: Will my new Z10 need a BIS (BlackBerry Internet Service) or a BES (BlackBerry Enterprise Server)? The answer is no. With the revamp of the BlackBerry OS, the platform now uses a standard data plan instead of the previous specialized plan.
Those of you currently on a one of two BlackBerry plans won’t have to make any changes, other than getting a new microSIM card for your Z10 or Q10. The only downside is for those who were on a less-expensive, BBM/email data-only plan won’t work on the new BB10 devices. You will have to pay up for a standard data plan when you upgrade.
Good bit of info to know as you will have to wait another month to actually buy one here in the states.
