Quick definition: APN stands for Access Point Name. It’s a gateway between a cellular network and the Internet. Any time a cell phone or IoT device uses data, its Mobile Network Operator (MNO) reads the APN to assign the device an IP address, determine what kind of network access it needs, and implement security measures.

What Is C-V2X? Cellular Vehicle-to-Everything Explained
C-V2X is one of the main ways IoT is being used in transportation. It utilizes cellular IoT to enable vehicles to understand and react to their environment in real time. While perhaps the most obvious application is that it enhances automation in driverless cars, it also improves the information drivers have at their fingertips, particularly when it comes to navigation and visibility, and it can simplify toll and parking systems.
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.”)
PTCRB: Certify Your Cellular Devices for NA Markets
Members of the PTCRB facilitate tests according to the certification program. The Cellular Telecommunications Industry Association (CTIA) manages and supervises PTCRB certification. Once a cellular device passes the necessary tests, one of three reporting bodies (CTIA, TÜV SÜD, or TAF) will assign it an International Mobile Equipment Identifier (IMEI), which tells North American cellular operators that the device is PTCRB certified (and therefore compatible with their network).
