Error code index

You may encounter errors not listed here, but we try to keep this list updated. If you get an error it will always be accompanied with an error description, so this list provides a reference, but you don’t need to know all these.

All error codes in follow the same pattern. They are a 32-bit unsigned integer, often represented in hex format as four hex chars, ie. 0x104A. The first two hex chars (first byte), represent the origin of the error. The following list of error codes are divided into sections depending on the origin.

General error codes

Regardless of the error origin, all error codes that end in 00-0F, have the same meaning. These do not map to a specific error, but may be caused by different issues depending on the context. Thus these are left undocumented since the exact cause varies.

Code Description
00 Success (no error)
01 Unknown error
02 Generic NACK
03 Operation not permitted
04 Input/output error
05 Shutting down
06 Insufficient Resources
07 Permission denied
08 Invalid Argument
09 Resource temporarily unavailable (EAGAIN)

This means that if you get an 0x1001, it’s an “Unknown error” from the SMS Errors. If you get an 0x0308 it’s an “Invalid Argument” from API Errors etc.

API Errors

These cover codes 0x0100-0x07FF. You might encounter these when communicating with one of our API’s ie. REST API.

SMS Errors

The following table is an exhaustive list of error codes that might be returned to you in a Delivery Status Notification. We do our best to keep track of all these, but some may be missing. Not all error codes are relevant or expected to occur in normal operations. This section covers codes 0x0100-0x01FF.

These supplement the States and status codes to provide additional insight on failures.
