Website to top up gems using network providers

Hi everyone! Or @Petri (since ur the only staff i always see in GS, lol!)

Do we have website where we can buy gems like top up load website using our network providers aside from atm cards or credit cards, like here in the philippines the popular network providers are sun, globe, and smart. There is a famous international online game here called Mobile legend and u can access codashop website to buy gems/diamond using top up loads through networkprovider, like globe.

If we have existing mode of payment using network providers where can i find it and how do i use it (detailed/comprehensive steps pls. Lol!)

Thanks in advance for your feedback.
