Hello,
That model is an iPhone SE (3rd generation) for sale in (other countries and regions). Here is the model breakdown:
- A2595 (United States, Canada, Puerto Rico, U.S. Virgin Islands, Guam, Mexico, Saudi Arabia)
- A2782 (Japan)
- A2784 (Russia, Armenia, Belarus, Kazakhstan, Kyrgyzstan)
- A2785 (China)
- A2783 (other countries and regions)
The specifications shows the following for the SIM Slot:
- nano-SIM and eSIM (A2595, A2782, A2784, A2783)
- nano-SIM (A2785)
Depending on the country, your iPhone may only have an eSIM, but should still have a nano-SIM slot (iPhone SE is not compatible with existing micro-SIM cards). Location should be on the right side about in the middle per the diagram on Apple's website, as MightyGem mentioned:

If for some reason that slot is not there, I would confirm the model and that it is a genuine Apple iPhone SE. You can enter the serial number here:
Check Device Coverage
Depending on the cellular carrier you use, you may need to use the eSIM instead.
Feel free to upload some photos of the phone.
