Hi Amatson,

About failed to change RAT to LTE, would you check “cm info”?  
FX30 has different variant, 3G only or 3G/LTE, if it shows “WP8” then this unit is 3G only.

For “cm data connect” failed, is it possible to test different SIM card on your FX30?  
Does the current FI elisa SIM works on ordinate cellular phone?

The error “204” is similar to this post: [AirVantage service failing to connect - #9 by rkirk](https://forum.legato.io/t/airvantage-service-failing-to-connect/3451/9)  
Are you connecting Windows PC with FX30 over USB? If yes, would you please check does Windows start mobile connection automatically?

Thx
