Refilling Happy Dtac Edge Account

[Digitalbanana 4893]

I've got over 1500THB in my HAPPY SIM card for phone calls and sms, but cannot see how to transfer some of it to my HAPPY EDGE internet account. Web site says can refill internet by Thai credit card (don't have one) or by Internet refill coupon available from shops. Is this the only way? Is there a quick online or on phone way to transfer? Now my internet balance is 0THB since I used up the allocated 20hours /month and get charged at much higher / minute rate until end of account month.

Go along to the DTAC shop and ask to change your promotion

For example say, I want 50hrs for 100bht a month, they deduct 100bht from your airtime right away and you get 50hrs.

They have a service number and you can call them. Look up their website, online services, internet. There they have the packages and code words for it which you need to SMS them. They will deduct from your credit. No need to go to the shop.
