I’m pretty sure your cobbled together hackathon project wouldn’t be functional as a phone, cell towers wouldn’t communicate with it and it wouldn’t make calls. Also, where did you even get backers? How did you attract them and scam them out of their money? And now you’re using them to outsource your labor team??
Pick one of the many chipsets that are used in Mobile devices. Slap that baby on the circuit board next to the processor and ram. I’m pretty sure your can get these packaged on a small surface mount board with shielding and everything on it already.
I guess you don’t realize that there is easy to use pcb design software that lets you lay out your components and it will automatically run the traces between the board layers. You can them send those files off to a board manufacturer who will also solder the components on for you for an additional cost. It’s not prohibitively expensive. People do it all the time
People do not make functional DIY cell phones all the time.
I don’t care if you can hack together something in your garage, it’s not a phone unless it can make calls using cellular infrastructure. That requires licensing, contracts, and business connections to the providers.
A project like that is good for making shortwave radios to avoid Israel installing bombs on your battery, but not useful for this specific purpose outside of making a prototype model to maybe be able to beg for money from investors.

Market barriers are real.
It’s called a modem and a SIM card sweetie
That’s not a cell phone? Pretty sure you’re stuck to an internet connection.

You can buy this thingy

You could place similar circuitry on the same board as the soc and other stuff.
Here is a cellphone with off the shelf parts.
