Question: Will I need to continue paying a subscription for the DNSimple account once I transfer my domain?
Answer: Currently, DNSimple offers a 30-day free trial after creating your account and your domain is transferred, after that it has the minimal cost of $6 month. (Reference DNSimple for up to date Pricing)
You can feel free to contact DNSimple to change your pricing plan.
After the 60-day lock by ICANN, you can change your domain to a different host provider; you will need to reach out to DNSimple support. Here is a link to the DNSimple article that will be helpful:
