UNBLOCKING SMART PREPAID SIM

Using SMART prepaid sim (just like GLOBE) with VPN's will surely hide your identity and will allow you access internet for free.  When Globe Telcom blocked their subscribers from doing so, butas trick was born.  Since many users were not able to unblock their sims, they shift to SMART.
But time also came for Smart subscribers.  Many SMART users simply noticed that they couldn't use their VPNs anymore.  Some said, they couldn't even send text messages.That is, they were also blocked by SMART Telcom.
Butas trick is not possible for Smart sims, thus ROAM OFF trick was discovered to be effective.
To unblock your sim and continue using VPN, simply type ROAM OFF then send to 333.
Now you can use your smart sim again to connect your favorite VPN.You may also try it using cproxy if you want.
