May 10, 2018 Battery Warning: Mobile Beacon, supplier of the non-profit Sprint based plans available through organizations like Calyx and PCs for People is tracking an unusually high number of reports of swollen batteries and even fires caused by this device. No recall has been published yet. Given that this device does NOT have a user replaceable battery - we advise high caution with this device. Keep an extra close eye on your unit for signs of battery swelling and discontinue use immediately if you notice any.
To reduce chances of battery swelling, we advise not keeping this unit plugged or charging 24/7 (unplug it for a few hours a day) - and be extra cautious of running consistent high loads on it, especially in weak signal areas which requires more power usage. For maximum safety, discontinue use entirely.

ZTE Restrictions In the United States:
ZTE is a Chinese company that produces a variety of electronics, including consumer cellular devices as well as network equipment that can potentially be used by cellular carriers and other internet service providers.
Beginning in 2018, the US government restricted the sale and support of ZTE products in the US due to security concerns. Then, in November 2022, the US government stopped certifying any ZTE products (along with products from Huawei and other China-based companies) for use in the US. This effectively means that ZTE cannot legally sell new products in the US anymore.
Existing ZTE products, like the ones listed here on MIRC, are still FCC certified and legal to utilize. The FCC does have the authority to revoke existing licenses for this gear, but we think that is unlikely to happen. Those using existing ZTE devices can continue to utilize them as normal.

Purchasing Options
Mobile hotspot devices are small, self-contained units that receive a cellular data signal and transform it into an internet connection. They are a cellular modem and router combined. Most can create their own personal Wi-Fi network.
They are typically designed with a specific cellular carrier in mind and require a suitable cellular data plan of their own to operate. You might see them called Jetpacks (Verizon's term for them) or MiFi (Inseego's name for them).
