In Settings>General>About>Model Number, tap twice and you should see the univocal code "Axxxx" (where xxxx are four numbers).

A3101 (Canada, Guam, Japan, Mexico, Saudi Arabia, and U.S. Virgin Islands),

A3104 (China mainland, Hong Kong, Macao),

A3102 (other countries and regions)

Details: iPhone 15 Pro has a 6.1-inch1

all-screen Super Retina XDR display with the Dynamic Island. The back

is textured matte glass, and there's a contoured-edge titanium band

around the frame. The Action button is on the upper left side, and the

side button is on the right side of the device. There are three cameras

on the back: Ultra Wide, Main, and Telephoto. There's a LiDAR Scanner on

the back. There's an LED True Tone flash on the back. In the United

States, there is no SIM tray. In other countries or regions, there's a

SIM tray on the left side that holds a "fourth form factor" (4FF)

nano-SIM card. On the bottom there is a USB-C connector for charging and

transferring data.

Where it's manufactured is irrelevant, what matters is the country the phone was made for.

iPhones made for China, Hong Kong & Macau do not have eSIM capabilities.

I dont have esim capabilities also. My iphone is made from singapore. Do u have idea whats the problem?

Because IPhones from Singapore doesn’t have Esim but are capable of using 2 Physical nano sims.
