Demand Surcharge: Roam to Residential Lite

Have just gotten starlink (only the hardware without the plan), I activated it and originally took the roam plan just to see how things go since I didn’t want to go for the residential plan due to the demand surcharge. I decided to swap to residential lite as I saw I only had to pay for the price difference and my usage is not that high. I only paid the price difference for the plan swap, it didn’t ask me for any demand surcharge. Will it charge me in the future?

Thank you in advance!
