Sun Cellular is one of the top carriers in the Philippines and they have introduced the BlackBerry Social Plan 600 to give you more for your money. It is a postpaid plan and as the name suggests, gives you unlimited BBM, as well as unlimited access to social networking sites - Facebook, Twitter. You also get unlimited calls and texts to Sun Cellular numbers, all for P600 per month.
You can get the BlackBerry Curve 8520 free on the plan, while other models require an upfront fee depending on the BlackBerry smartphone of your choosing. Contract length, which Sun Cellular calls 'Holding Period' is for 30 months.
If you are more of a data hungry BlackBerry user, Sun Cellular do offer the alternative BlackBerry Data Plan 600, where you get unlimited internet access and unlimited email. With this plan you'll only get 200 texts to Sun Cellular numbers.
