Anyone knows if it is actually possible to refill/top up a 1-2-call sim card online, by using credit card or paypal?

I can not find it anywhere.

look at the menu on the left of the page when loaded.

Change to English top rht corner.

Not sure you can do as you ask but if you have a Thai bank account and online banking then it is easy to do.

Hopefully the above link posted by CharlieH will give you options you can use if you not have A Thai bank account

4. Click Request Password
   
5. You will receive a one time password by SMS put it in the password box
   
6. Click OK
   
7. Click on My eService
   
8. Click Top Up
   
9. Click Credit Card/Debit Card
   
10. Follow the prompts

Or there are guys selling topups on eBay, you pay them then provide your number for the topup by the look if it.
