What Is a Mobile Hotspot? How to Use It

Q: How much data does a hotspot use?

The same as the activity on the connected device. Browsing is light, but HD video streaming can use 1 to 3GB per hour, so hotspot data adds up quickly.

Q: Is a mobile hotspot the same as tethering?

Essentially yes. Tethering is the general term for sharing your phone's connection; a Wi-Fi hotspot is the most common way to do it.

A mobile hotspot turns your phone into a portable Wi-Fi router, letting your laptop, tablet, or other devices get online using your phone's cellular data. It's one of the most useful features on any phone — and most people already have it built in. Here's what it is and how to use it.

What a mobile hotspot actually does

When you turn on your hotspot (also called “tethering”), your phone broadcasts a Wi-Fi signal that other devices can join, just like home Wi-Fi. Those devices then use your phone's mobile data to browse, stream, or work. It's perfect for getting a laptop online at a coffee shop, keeping a tablet connected on a road trip, or staying productive when your home internet goes down.

How to turn on your hotspot

iPhone: Settings → Personal Hotspot → toggle “Allow Others to Join.” The Wi-Fi password is shown on the same screen.
Android: Settings → Network & internet → Hotspot & tethering → Wi-Fi hotspot (wording varies by brand).

On the other device, open Wi-Fi settings, select your phone's hotspot name, and enter the password. That's it — you're connected.

Things to keep in mind

Hotspot uses your data. Everything your connected devices do counts against your phone's data — and video or large downloads add up fast.
It drains your battery. Keep your phone plugged in during long sessions.
Some plans cap hotspot use separately from regular data, so it's worth knowing your plan's limits.

Make sure your plan has the data for it

Because hotspot use eats data quickly, the right plan matters. EcoMobile's tiered prepaid plans — from 2GB up to 50GB — let you pick the amount of high-speed data that matches how you use your hotspot, all on nationwide 5G with no contract and no credit check, starting at $10/month. Compare plans to find the right fit.
