Any way to connect a sim card to laptop for cellular data service? can you get a sim card to USB adapter or something else of the sort?
Yes, depending on where you are from, they’d call them SIM card dongles or adapters. They tend to be USB Modems, and are fairly easily available on Amazon and other places.
We needed specific driver/launcher to connect to the data network on Windows, but worked very easily on Linux.
Can you provide any links to SIM card dongles or adapters?
As of today, most USB modem adapters you will find on the web are probably risky Chinese stuff. I highly recommend buying instead a mobile hotspot router (still, you should do some research) from a reputable brand.
PS: Use guides like this Best mobile hotspots in 2022 | Tom's Guide, but you should also check forums.
My ghetto solution: power bank + 2nd phone + NFC tag (to activate / deactivate hotspot on the phone)
