There are two types of top-up to your account to send message including Auto top-up and One time payment. To access on it, you click the button "Top-up" at the bottom left corner.
1. Auto top-up
When your balance falls below a certain threshold, top-up amount will be automatically added money to your balance based on your setting. However, to avoid top-up amount of your balance go over, the system allows you to set monthly top-up limit, so we won't auto top up until next month or until you increase the limit.
2. One time Payment
Your balance will be toped up one time with one time payment function.

Firstly, you click on the text "One time payment".
Secondly, the pop-up shows and you have to select your top-up amount, then click on the button "Top up"
Thirdly, you continously click on Approve charge to complete the process
Finally, you will get the annoucement about your balance after top-up
