Compatible with TD-M15 TD-G100 4G POC Walkie Talkies - Nationwide

In this review of the TD-G100 POC two-way radio, the bottom line is simple: this unit is best for teams and families who need reliable, coast-to-coast voice communication without worrying about traditional radio range limits. The TD-G100 uses U.S. 4G networks and ships with an AT&T SIM that provides 12 months of included data, making it a practical choice where cellular coverage exists. The biggest reason to buy is the combination of true nationwide reach and straightforward app-based features that let users program radios and manage groups without complex hardware setup.

Key Features

• Unlimited Range Walkie talkies: Uses U.S. 4G networks to maintain stable communication across long distances, effectively removing line-of-sight restrictions.
• 12 Months with No Monthly Fees: Each radio includes an AT&T SIM and one year of complimentary device-only data so teams can start communicating immediately.
• One-Click Auto-Update (OTA): Firmware and feature updates install over the air with a single step, keeping the device current without physical cables.
• Auto-recording function: Group calls and chat history are recorded and accessible to members, which helps prevent missed information and aids documentation.
• 3000mAh battery: A high-capacity battery delivers long runtimes of roughly a day in typical use and recharges via a Type-C cable for convenience.
• 2W Loud Audio Speaker: A powerful speaker provides clear, high-volume audio suitable for noisy work sites and outdoor environments.

Who It's For

The TD-G100 suits families, logistics teams, event staff, and small companies that need instant push-to-talk communication across cities or states without relying on conventional radio licensing or repeaters. It is especially useful where smartphone push-to-talk apps are less convenient and a dedicated hardware button is preferred.

Those who should look elsewhere include users operating in areas with no 4G coverage or teams that require secure, encrypted tactical communications beyond consumer cellular networks. If you need an ultra-compact short-range handheld for isolated off-grid use, a conventional VHF/UHF radio may be a better fit.
