# 33121: Invalid Parameter Combination

Log Type: APPLICATION

Log Level: ERROR

## Description

Raised whenever a request contains conflicting parameters.

### Possible causes

* While updating your SIM, the request was rejected because you cannot update `Status` and `ResetStatus` simultaneously.
* Updating a SIM's status to `suspended` and removing its Rate Plan is not permitted.

### Possible solutions

* While updating a SIM, ensure not to update `Status` and `ResetStatus` within the same request.
* While updating a SIM, you cannot simultaneously update its `Status` to `suspended` and remove its Rate Plan.
