Help sun sin not working with gigalife app

[axy_david]

Hi, I noticed that I can successfully register using the gigalife app but when it comes to actually logging in I get spam of sms from sun saying:
"Sorry for the inconvenience. Service unavailable at this time (transaction not charged). RC: 1440"
The app works fine with my smart Sim. Any ideas why?

Saan nakalagay yong Sun sim mo? Sim1 o Sim2?
