Hi @walker7811
Welcome back to the Auth0 Community!
Thank you for posting your question. I’ve checked with our documentation, and upgrading your plan to Essential won’t add 1000 M2M tokens to your existing limit. Still, it would allow you to exceed the quota for the month, so it would probably be the best solution for this month, as the quota will reset in the next month. You can read more about that here → Auth0 Quota Exceeded
Thanks
Dawid
