Yesterday, I registered to GoUNLI80 promo. I can access facebook, Line and Kakao talk but when I send group messages or message, it wont send and when I call some of my friends (which are TM/GLOBE users too) it says that I don't have any money left in my account. What's Happening? Is there something wrong? I have a balance of 4 pesos in my account, Isn't that enough?
