My Question or Issue

My Spotify Premium ended today and I can't resubscribe because I can't see my carrier under the 'carrier tab' on the Mobile Payment page. It's so frustrating, someone help.

(Image shows options under the carrier tab include Sun, TNT, and Globe. Smart is nowhere to be found!)

So... apparently putting 'SUN' as the carrier works, turns out it's not accepting my payment bc of this weird one-time pin thing between SMART and Spotify. Hopefully they fix this soon!
