First, Smart prepaid, postpaid, TNT and Sun Ceullar can get free Twitter access by texting DEARPOPE and send to 9999. This is only one registration process that will last until January 19. I tried to register to my Smart Bro prepaid number but it's not working. What's good (according to one CSR that I talked to Smart Hotline) is this promo is open to almost all kinds of smartphones (Android, iOS, BB and Windows - not sure yet for Firefox) . After you sent the keyword, you'll get a reply text that you're now registered. You can either use any mobile browser and go to mobile.twitter.com or use the Twitter app to avail of the service. No minimum load balance required. Smart recommends to tweet with #DearPopeFrancis to send your tweets to the Pope.
