Network Selection Explained
By default, cellular devices connect to “home” network of the provider that issued their SIM cards. Cellular connectivity providers also have strict agreements with other operators in countries their network doesn’t cover, so whenever your device is outside its home network, the SIM card will connect your device to your provider’s preferred partner. (This is what’s known as “steered roaming.”)
LPWAN Explained: Low Power Wide Area Networks
There are several kinds of LPWANs, but they all share some general characteristics, and they’re ideally suited for IoT applications. The type of LPWAN you choose determines the radio frequency (RF) bands, data rate, and cost structure your device uses.
2G and 3G Sunsets: When They’ll Happen and How to Prepare

But the technology is decades old, there are better solutions available, and there’s only so much bandwidth to go around.
