Finding a stable 5G Module for X86

Hi guys! I'm planning to make a 5G sim card router on x86 as I have some parts left.

Now I am finding a 5G Module that can works well on Openwrt, and mini pcie will be much suitable than m.2 for me.

Any recommendations on modules? Or suggestions on my projects? Also, what is your experience on 5G sim card with Openwrt? (Support, Performance...etc)

I ve read about m2 modules in for rpi so working for x64 as well so be prepared to spend a few hundred bucks on this thing

Wow that's not cheap lol.
