Hello Samantha777,
Welcome to Apple Support Communities.
We understand that you want to activate eSIM on your iPhone 14 Pro Max with Patriot Mobile. We are happy to help.
While T-Mobile is a carrier that offers eSIM service, we don’t show Patriot Mobile listed here: Find wireless carriers and worldwide service providers that offer eSIM service - Apple Support
Here’s more about activating eSIM: About eSIM on iPhone - Apple Support
"What you need
eSIM on iPhone is not offered in China mainland. In Hong Kong and Macao, some iPhone models feature eSIM. Learn about using Dual SIM with two nano-SIM cards in China mainland, Hong Kong, and Macao. For travelers visiting China mainland who wish to use an eSIM for prepaid data plans, these are offered by many worldwide service providers.
* iPhone 14 models that are eSIM only can activate without a Wi-Fi network."
Let us know if you have further questions.
Take care.
