Well that didn't take long. I received an email
this morning from Starlink. They are now going to charge $25 usd a month if you want portability.
Here's the information from their FAQ:
What is Starlink's Portability Feature and Policy?
For an additional monthly fee, the Portability feature enables users to temporarily move their Starlink to new locations in order to receive service
anywhere within the same continent Starlink provides active coverage. To see active coverage areas, please view the Starlink Availability Map. Portable users are served best effort and can expect lower service
levels than fixed users, particularly in areas marked as "Waitlist" on the Availability Map.
Add Portability on Your Account:
If you are an active customer, you can enable Portability from your account page and it will take effect immediately.
If you have multiple Starlinks, Portability must be selected and purchased for each location.
When you enable Portability, you are charged on your next monthly invoice. Portability is charged in full monthly increments and cannot be pro-rated. The Portability feature and billing charges will be ongoing until you decide to disable it. Once you disable Portability, the recurring charge will stop after your next monthly invoice and Portability will only remain active for the remainder of the current
billing cycle. For example, if you enable Portability on March 12th and your next billing date is on April 1st, you will be charged $25 on April 1st for the full previous month.
Best Effort Service: Portability service is provided on a best effort basis. Stated speeds and uninterrupted use of services are not guaranteed. Starlink prioritizes network resources for users at their registered service address. When you bring your Starlink to a new location, this prioritization may result in degraded service, particularly at times of peak usage or network congestion.
International Travel: Starlink can only be used within the same continent as the registered Service Address. If you use Starlink in a foreign country for more than two months, you will be required to move your registered service address to your new location or purchase
an additional Starlink to maintain service.
No In-Motion Use: We do not support Starlink use in motion at this time. Using the Starlink Kit in motion will void the limited warranty of your Kit. While our teams are actively working to make it possible to use Starlink on moving vehicles (e.g., automobiles, RVs, boats), Starlink is not yet configured to be safely used in this way.
