If your USB Modem or WiFi Hotspot is currently on the Telstra 3G/NextG network, then it is also compatible with the USA sim card (because, coincidentally, Telstra use the same frequency as AT&T).
Many other USB Modems and WiFi Hotspots are compatible, but you'll need to check if your device uses any of the following AT&T frequencies:
- 3G/UMTS 850/1900 MHz
- 4G/LTE Band 2 (1900 MHz), Band 4 (1700 MHz), Band 5 (800 MHz), Band 17 (700 MHz)
You can do a Google search for you device, and search for its specifications and check the frequencies that it operates on.
