Thinking about opening an eSim operation

I'm considering opening an automated eSim company that will practically be a digital dropshipping.
The investment is insignificant as I can build my own WordPress or WooCommerce site (I'll need to pay for API integration/make).

Do you have any thoughts about the industry?
Did you use this kind of service?
How was it?

What are you trying to sell exactly i don't think we understand
