Activation of a DJI Mini 2SE

When doing the activation procedure a cell problem has occured.

I have reloaded de DJI Fly software and redo the activation procedure but the controller does connect with the drone and there is no message telling me to complete the activation and I have a message in the bottom right corner that says in french "Voir la camera"
But if I select this option it shoe that the unit is not activated.

What would be the other procedure to activate the unit.
Tank you for your help
