Sim on my phone not working anymore

[the_santa23]

I was on a Voxy data plan on my phone and I decided to connect my new iPad eSim and my phone number via PAC. The eSim is working good but I'm out of my voxy plan now and the sim in my phone is no longer working, I want to know how to change the eSim number and try to get back the plan in my phone because it won't work.
