What happens when I run out of credits?
Updated 29 September 2026
The Short Answer
PropKaki checks what is left before it sends. If a send would take you past your balance it stops before anything goes out and tells you how many more credits you need. You are charged only for what went. On a paid plan, a Credit Pack is 50 credits for S$6 and lands immediately.
Running out mid-month is a normal thing that happens on a busy day. It does not break anything.
Will a send go out half-finished?
No. PropKaki checks what is left before it sends, so a group that would take you past your balance stops first. You are told how many more credits you need, and nothing has gone to anyone.
Am I charged for the part that did not send?
You are charged for the messages that go out. If 12 of a group of 40 went before you ran out, you are charged 12.
How do I carry on straight away?
- Open Account Settings → Usage.
- Under Top-up credits, press Top up — 50 credits for S$6.
It lands immediately and shows as Top-up credits, separate from your monthly allowance. Nothing holds it back, so you can finish the send you were in the middle of.
On Free there is no pack to buy. That row reads More credits and its button is See plans.
Should I top up or change plan?
A pack is the right answer for one busy month. If you are buying one most months, the next plan up is usually cheaper:
| Plan | Per month | Credits a month |
|---|---|---|
| Free | S$0 | 50 |
| Basic | S$50 | 500 |
| Pro | S$100 | 1,000 |
| Max | S$150 | 1,500 |
You can change plan in Account Settings → Billing.
