Why are my calls or SMS messages failing?

Last updated: November 12, 2026

If your calls or SMS messages aren't going through, there are a couple of things to check.

Check your telephony balance

If calls and SMS were working normally but suddenly stopped, you may have run out of credits.

Go to Company Settings → Usage to check your balance and add funds if needed.

Verify the recipient's number

Make sure the phone number is correct. For SMS messages, the recipient must also be linked to a record in Coperniq.

Still having trouble?

Refresh Coperniq and try again. If the issue continues, contact Coperniq Support with the affected phone number and record link so we can investigate.
