The balance ran out
During a call SpareLine keeps setting aside balance to cover it. When there is no more to set aside:
- the app shows Low balance, then Call ending soon, with an Add balance button
- if no balance is added, the call ends
The call ends rather than continuing into debt. Adding balance during the warning keeps the call going. See Why money is set aside during a call.
The connection dropped
SpareLine calls go over the internet. If Wi-Fi or mobile data drops or becomes too weak, the call can end. Moving between networks can also interrupt a call.
What you are charged
You pay for the time the call actually lasted.
If it keeps happening
Send a message from Account → Help & support and choose An outgoing call failed. Pick the call from the list, and support can see what happened to it.
