Sun Cellular puts customer convenience at the core of its commitment when it recently launched IDD Top 10, a permanent service available to Sun subscribers that allows them to enjoy IDD calls to their relatives and friends for only US$0.10c a minute starting on the first minute.
Unlike other cellular service providers which only offers affordable IDD call to the top 5 countries with high presence of OFWs and Filipino migrants, Sun’s IDD Top 10 allows its prepaid and postpaid subscribers to make calls to a total of 10 countries, namely the US (Mainland), China, Hong Kong, Singapore, Canada, Thailand, Malaysia, Brunei, Guam and Macau.
Using the IDD Top 10 service is easy. All you need to do is dial from your mobile phone to get better voice quality connection without a need for a computer or an Internet subscription.
Postpaid subscribers simply need to enroll their account in order to enjoy the US$0.10c a minute IDD rate. Once approved, a "consumable" fee of
R200 will be charged to their Monthly Subscription Fee (MSF).
Meanwhile, prepaid subscribers need to load an IDD Top 10 call card or convert their regular load to enjoy the lowered IDD rate. With this new service, prepaid subscribers get approximately 18 minutes of IDD credit (subject to the prescribed FOREX rate) valid up to seven (7) days from your initial load of only
R100. There are four reloading options available to make reloading easier and more convenient: via call card, e-PIN, load purchase through text, and load purchase through The Mall.
