You could look into LoRaWAN. If you're lucky there will be a gateway nearby (within about 100km), and you can piggyback onto that.
If you really want to connect a Pico to 4G you'll need a modem. Most of them use a serial interface, so that's easy. You might find a library to make things easy for you.
However, a Pico is just a microcontroller, so any microcontroller techniques that have been around for a while could be applied to the Pico. Here's an old discussion about doing the same thing with an Arduino. Expand your search to find more background.
