I have a starlink mini that I use for the camping and I recently got a message that say that I need to reactivate my service plan which is the Roam 100GB. So I proceed and try to reactive the said service plan but I cant find my current plan in the list and there's no option to reactivate the current one.

When I ask the grok AI agent inside the starlink app it say that to many people use the same plan as me in the same area is that true?
