A message was not sent or not delivered

Last reviewed 26 September 2026

A message can be refused before it is sent, for example when the number does not carry SMS, the balance is too low, the text is too long or the destination is not supported. It can also be sent but not delivered by the receiving network, and the app then marks it "Not delivered".

Refused before sending

SpareLine checks a message before sending it. It is not sent when:

  • the number does not carry SMS. Send it from a number that does. See Text messages on SpareLine numbers.
  • the balance does not cover it. Add balance and send again. See Adding money to your balance.
  • the message is too long. Split it into shorter messages.
  • the destination is not supported. SpareLine sends messages only to destinations it can price correctly.
  • messages are sent too quickly. Wait a moment and try again.
  • the account is frozen. See My account is frozen.

Sent but not delivered

A message that was sent can still be refused by the network it was going to. The app then marks it Not delivered. Check the number you sent it to and try again later. If it keeps happening with the same number, the receiving network may be refusing messages from virtual numbers.

Still stuck?

Send a message from Account → Help & support, choose Messages and pick the number you were sending from.
