What happens during a call
- Before the call connects, SpareLine checks that your balance covers the first few minutes, and sets that amount aside. If it does not, the call is not started.
- While the call runs, more is set aside as the call goes on, a little at a time.
- When the call ends, you are charged for the time it actually lasted, and what was set aside but not used is released back to your balance.
This is why your available balance can look lower during a call than the call has cost so far.
After the call
The final charge is settled when the call's cost is confirmed, which usually takes a few minutes. Until then, some of your balance stays set aside for it — however long that takes. Once the charge is settled, what was set aside but not used is released.
If your balance runs out
When there is no more balance to set aside, the app warns you during the call, with time to add balance. If none is added, the call ends. It does not continue into debt. See Why a call ended.
