# 83704: Attachment Rejected Due To SIM In New State

Log Type: APPLICATION

Log Level: ERROR

## Description

The SIM was not able to attach to the specified network because your SIM has not been activated yet and is in the `new` state. This is the state that SIMs arrive in when they are shipped and they must be activated first via Console or REST API before they can be used.

### Possible causes

* Your SIM is in the `new` state and is not active.

### Possible solutions

* Use the Twilio Console or REST API to activate your SIM by setting its `status` to `ready` or `active`.
