After Smart Communications rolled out their two of their latest prepaid offers, Smart Calls30 and the all-new Smart UCT, they are targetting this time those Smart prepaid users who need to call on any mobile network at a fraction of a cost compared of doing those Php 7.50/min. of call
Smart Express Call 50 gives you 50 minutes of calls to all networks for Php 50 pesos valid for 3 days.
Good thing, their official Twitter account gave me a clarification on the missing bits, registration and terms and conditions. To register, just text EC50 and send to 9999 but there is a catch just like in Smart Calls30. If you need to register to the said service, you must be subscribed to Smart All Text 10, Smart All Out Surf 20, Gigasurf 50, Unli Call and Text 30 or 50 to avail it. When you already registered to EC50, just dial the mobile number just like a regular call. No prefixes needed.
As of this time, Smart Express Call 50 is available until further notice (no end of promo date so far)
