Many customers ask if the N39plus is restricted to AT&T, or if it supports other major carriers like Verizon and T-Mobile.
The short answer is: No, it is not locked to AT&T. It supports all major networks!
Here is a simple breakdown of how your radio's network connection actually works, along with a list of supported carriers in North America.
Your N39plus uses a Smart VHAM Data SIM (a multi-carrier virtual network service). Instead of being locked to a single provider, the radio constantly evaluates your current location—whether you are in a dense city, a small town, or a rural area—and automatically connects to the strongest available network.
When Stationary: Under normal communication conditions, the radio locks onto the best local network and stays there to ensure a stable connection.
When Driving/Traveling: If you drive across different cities or regions, the radio will automatically switch to the optimal carrier or frequency band to maintain the best call quality. (Note: During this transition, the radio may briefly refresh its connection to lock onto the new, stronger tower).
You do not need to configure these settings yourself—the radio handles it automatically. However, for reference, here are the networks and bands your N39plus supports:
