Twilio offers APIs for programmable calls and messages across multiple platforms, which can help with marketing and customer outreach. That said, Twilio isn’t perfect and runs into random bugs and errors from time to time.
In this article, we’re talking about the Twilio error code 30006, its causes, and how you can fix the problem.
What causes Twilio error code 30006?
The error is triggered when there’s a delivery issue to the target device, especially when the target device is a landline. Possible causes include:
- The destination number is a landline.
- The carrier is unreachable.
- Outage on the carrier’s end.

How to fix Twilio error code 30006?
Here are five fixes you can try out.
Use the Lookup API
The first thing you should do all you need to do is run your target number through the Twilio Lookup API to determine if the number is a landline. If it is, try with an alternate phone number type as Twilio often has trouble delivering calls or messages to landline numbers.
Check Twilio’s server status
The first thing you should do is check the Twilio status page to ensure the service itself is up and running. You can do that by visiting Twilio’s social media pages or the server status page to check if there’s an outage. If there is, you’ll have to wait until Twilio resolves the error on its end.

Restart the destination device
Another thing you should try out in such situations is to restart the destination device. Restarting can resolve many seemingly random issues, primarily network or SIM issues. You can also try toggling airplane mode on and off.
Get better coverage
Poor network connectivity can cause several issues, including this one. Try moving to an area with better network coverage, ideally with a telecom tower nearby and try making the call again.
Contact Twilio support
If nothing else works for you and the target device seems to be working fine with other SMSs outside of Twilio, your best bet is to get in touch with Twilio’s Support team. Ensure you collect three or more message SIDs from the last 24 hours before opening a support request.
