Portable Wi-Fi Hotspots: SIM, Bands and Battery

SIM, bands and speed: what the hotspot itself must support

A mobile hotspot turns a cellular signal into a Wi-Fi network for laptops, tablets and consoles. It needs a SIM card with a data plan from a carrier, and the device must support that carrier's bands; a 4G unit is limited to LTE speeds, while a 5G unit adds faster rates where coverage exists. Check the Wi-Fi standard, the number of devices it supports at once, and whether the SIM slot is locked to one carrier.

Battery, power and the accessories listed here

Battery life and charging decide how useful a hotspot is away from a socket. Look for the battery capacity in mAh and whether the unit charges over USB while in use. Replacement batteries in this category are model-specific, with capacity and voltage such as 2,500 mAh at 3.6 V in one listing, so match the hotspot model before choosing. Mounts, charging stands and tripods are also listed; check their stated compatibility, as universal claims vary.

Questions about Portable Wi-Fi Hotspots: SIM, Bands and Battery

Is a hotspot better than tethering from my phone?

A dedicated hotspot saves your phone's battery and often holds more devices at once, while tethering needs no extra device or SIM. If you share a connection daily or with several people, a separate unit is easier.

Does a hotspot come with mobile data?

Usually not. The hotspot is the radio and Wi-Fi router; data comes from a SIM card and a plan from a carrier. Confirm that the hotspot is unlocked or compatible with your carrier before choosing a plan.

How many devices can one hotspot connect?

The stated device limit varies by model, from a few devices to a dozen or more, and speed is shared among all of them. Check the limit in the specifications and remember that each active device lowers the speed the others get.
