3 / Three / Tri as one of the operators that is quite popular because the quota is relatively cheap, only the range of the signal is somewhat less than outside the city. The saving of unused credit is because today the data quota that is often used, obviously makes it pile up. Well ... because there are nephews who ask for credit for topping the PUBGM game, I automatically find out how to do it or not, and how.
Long story short, it can indeed and there are 2 methods that adjust to its convenience. Without further ado, please follow what you want.
3 / Tri credit transfer via USSD dial
The alternative can be the solution below
Transfer credit 3 / Tri via the Bima + application
Which one is better? The Bima + is easier to use because all through the application, which dialed USSD must remember what key to press.
Oh yeah, there used to be an SMS method too. But I warn you that if you can't transfer Tri credit via SMS it can't, don't try it because it's just a waste of credit.
