Quick definition: C-V2X stands for cellular vehicle-to-everything. It’s a 3GPP standard that defines cellular technology that enables vehicles to communicate with transportation infrastructure, other vehicles, the cloud, cellular network infrastructure, and even pedestrians. While other technologies help facilitate V2X (vehicle-to-everything), C-V2X specifically refers to the cellular solution.

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.”)
What Is an APN? Access Point Names Explained
Basically, your APN defines your connectivity settings. And any time you change carriers, you need a new APN—because the name is specific to each MNO.
What Is Cellular IoT? Simple, Global Device Connectivity
Cellular IoT uses cellular networks to connect physical devices to the Internet. The same cell towers that provide service to your smartphone can connect heavy machinery, security systems, hospital equipment, asset tracking systems, and billions of other devices to the internet. Cellular connectivity enables these devices to transmit and receive data, so end users can remotely monitor, analyze, and control them.
