What Are Hotspots and How Do They Work?

What is a hotspot?

A hotspot is a wireless access point that lets you connect phones, tablets, computers, and other devices to the internet when you’re on the go. They’re built into most smartphones, but you can also get dedicated mobile hotspot devices that deliver faster speeds, connect more devices, and have a longer battery life than your phone. You can also find public Wi-Fi hotspots at many restaurants and public buildings.

Hotspots can hit speeds anywhere from 1 Mbps to 1,000 Mbps. They usually come with limited data restrictions—unlimited data on a hotspot is very uncommon—so they’re not ideal for replacing your home internet. Still, some providers have generous service plans that let you get a lot out of a hotspot each month.

Important hotspot terminology

Here’s a quick rundown of important terms you want to be familiar with as you learn more about hotspots.

Wi-Fi: A wireless internet connection. Although the term “Wi-Fi” is often used interchangeably with the internet, technically it refers specifically to an internet signal broadcast over a piece of equipment like a router or hotspot.

Cellular network: An interconnected set of computers and transmitters that exchange internet data over radio waves and let you connect devices over a hotspot.

Hotspot: A device that gives you a Wi-Fi connection. Hotspots are built into many smartphones, but you can also buy a separate mobile hotspot, or you can access the internet through a public hotspot at a restaurant or park.

Wireless local-area network (WLAN): A set of devices (including computers, phones, printers, and TVs) that are connected over a wireless network of radio and cellular signals. A hotspot sets up a WLAN that provides Wi-Fi

Cellular data: Digital information transmitted over a cellular network. You need data in order to use the internet, and you can get a “data plan” from a cell phone provider to make your hotspot work.

Service set identifier (SSID): A unique sequence of numbers and letters to name a Wi-Fi network. It’s basically the name of your hotspot, and you can identify it by pulling up the Wi-Fi dropdown menu on a laptop, tablet, or phone.

How does a hotspot work?

A Wi-Fi hotspot uses wireless data from a cellular provider to give you internet access for phones, computers, tablets, and other Wi-Fi enabled devices.

A mobile hotspot usually provides a connection over 4G LTE wireless technology, providing max speeds of around 30 Mbps. But some newer mobile hotspots have 5G capability, so they hit speeds from 50 Mbps to well past 1,000 Mbps in some places.

Do hotspots work without cell service?

Hotspots don’t work without cell service. Hotspots need cellular service to create a Wi-Fi signal. So you’ll need a data plan from your cell phone company or another provider to make your own hotspot work. And you’ll also need adequate cell service.

Broadly speaking, people also often use the term “hotspot” to describe any public internet access point that gives you a Wi-Fi connection. So that includes the free Wi-Fi at an airport, restaurant, or public library.

We have more info on public hotspots in our public Wi-Fi guide.

How fast are Wi-Fi hotspots?

Most Wi-Fi hotspots hit top speeds of around 30–40 Mbps.

However, speeds vary depending on the kind of hotspot you have and the cell service available. 5G hotspots reach much faster speeds, hitting 50 Mbps in the lower range while topping out at well past 1,000 Mbps in some urban areas (where millimeter-wave 5G is available).

Since a hotspot runs on a wireless connection, speeds can go up and down due to signal interference. That can happen if you’re far away from the nearest cell tower, and it can also be impacted by certain geographic landmarks in your area. Mountains, canyons, trees, and even bad weather can make it harder for a hotspot to pick up cellular signals.

Cell phone hotspots

A phone’s hotspot is the easiest, most affordable hotspot you can use. It comes built into your smartphone’s hardware, so you can switch it on with the tap of a button and use data straight from your phone plan (as long as your plan allows it).

You won’t always get a whole lot of data, and there’s usually a limit to how many devices you can connect—usually around 10 to 15. So this is the best way to go if you use a hotspot every once in a while. Otherwise you might want to invest in a dedicated mobile hotspot.

How do you turn on your phone’s hotspot?

Turning on a phone’s hotspot is very easy. Here’s a quick breakdown for iOS and Android phones:

Apple iOS phones and tablets:

Step 1: Go to Settings > Personal Hotspot. Or, depending on which model you have, go to Settings > Cellular > Personal Hotspot.

Step 2: Tap to toggle on Personal Hotspot.

Step 3: Switch on Allow Others to Join.

Android phones and tablets:

Step 1: Go to Settings and search for “hotspot” or “tethering.” Depending on the phone you have, it will be located in a menu titled Mobile Hotspot and Tethering, or Network and Internet.

Step 2: Tap to switch on the hotspot.

Step 3: On some phones, you’ll also need to switch on Wi-Fi sharing, which will allow the hotspot to be reached by other devices.

Once you’ve switched on your phone’s hotspot, go to the Wi-Fi menu on the device you want to connect to the internet. Look up the name of your hotspot and type in the password to connect to the internet.

In the same menu where you switch on the hotspot, you can also configure the password, network name, and other settings. And of course, make sure you’ve turned on your cellular data—the source of your Wi-Fi juice.

Specific hotspot instructions vary based on the phone you have. You can get more detailed instructions in our guide to phone hotspots.

Your phone likely already has a hotspot built in, so all you need to get the hotspot working is a phone plan that gives you hotspot data. We think T-Mobile’s Go5G Plus plan is the best you can get because it gives you a ton of data at a reasonable price.

These other plans will do great as well, although Visible’s budget-friendly plan comes with tight restrictions. You get only maximum 5 Mbps speeds, and you can connect only one device at a time. Stick with that if you’re on a low budget.

Mobile hotspots

Mobile hotspots are dedicated devices that give you a hotspot connection. They’re more expensive than phone hotspots, but they work a lot better for intensive hotspot use, connecting more devices and supporting faster speeds. You can also usually get more data for your buck from a standalone hotspot service plan than you could with a phone hotspot.

Most mobile hotspots run over 4G LTE wireless networks, so they’ll hit max speeds of around 25–30 Mbps. They typically connect 15–20 devices. You can find some 5G hotspots as well.

T-Mobile’s Inseego MiFi X PRO 5G gives you premium performance at a relatively affordable price. Able to support up to 32 devices, it delivers a solid connection over T-Mobile’s 5G and 4G networks, while its Wi-Fi 6 connectivity ensures that every device gets a stable connection. It has a powerful battery and comes with a USB-C port you can use to charge other phones and devices.

On the other hand, the Alcatel LINKZONE is a bare-bones model that gives you decent speeds (usually around 15–30 Mbps) at a truly bargain price. AT&T’s NETGEAR Nighthawk M1 has a long-lasting battery and comes with a range of security features. It also connects more than most hotspots. But it costs the most out of these three options, and AT&T’s hotspot data plans tend to be on the pricey side too.

How well do mobile hotspots work?

Mobile hotspots work very well. Although they generally don’t give you as much speed and data as a home internet plan, they give you a reliable connection in places and situations where it’s hard to get internet access. They’re especially useful when you’re on the road a lot, working remotely in a restaurant or coffee shop, or staying in a vacation home.

Best times to use a hotspot:

• Traveling (domestically or overseas)
• Working remotely at a coffee shop or restaurant
• Living in a rural area
• Staying in a vacation home

5G hotspots

5G hotspots are mobile hotspots that give you a connection over 5G wireless networks. There are only a few on the market right now, but they pack a lot more firepower than 4G hotspots.

They’re way faster and can hit speeds upward of 1,000 Mbps (in some places). They connect a lot more devices. And they have Wi-Fi 6 capability—the latest Wi-Fi standard, which keeps speeds consistent for multiple users on the same connection.

A 5G hotspot isn’t necessarily a must-have—you can still get great performance out of a 4G hotspot device or phone hotspot. But with their boosted capability, 5G models are excellent picks for businesses and schools. They’re also helpful if you do a lot of high-bandwidth activities since they tap into the fastest 5G speeds.

Best times to use a 5G hotspot:

• Sharing Wi-Fi with coworkers at conferences and conventions
• Using Wi-Fi as part of a school study group
• Connecting to Wi-Fi in an urban area (where you can get millimeter-wave 5G with gigabit–plus speeds).

T-Mobile takes the cake when it comes to 5G hotspots. As we discuss higher up on this page, the Inseego MiFi X PRO 5G is the ultimate hotspot device, with tons of features and powerful capabilities at an affordable price. On top of that, you can also get a flexible and generous data plan from T-Mobile, with prices starting at $10 a month for 2 GB and going up from there.

Verizon and AT&T both have great 5G hotspot contenders—the only catch is you have to shell out more bucks for most of the same features.

Travel hotspots

Technically, all hotspots work for traveling. But some hotspots are designed specifically for traveling internationally, giving you Wi-Fi either through a special data plan or via a SIM card from a local provider.

If you’re on a budget, it’s best to use your cell phone’s hotspot while abroad—that way, all you have to do is swap in a local SIM card to get data. But consider paying extra for a standalone hotspot device if you plan to use a hotspot regularly and don’t want to deal with finding SIM cards or working with international cell companies.

You can get easy Wi-Fi at any time with one of Huawei’s travel hotspots, which works with SIM cards from cellular carriers in Europe, Asia, the Middle East, and Africa.

Hotspot data plans: Can you get unlimited hotspot data?

You need a data plan to use a hotspot. So here’s the bad news first: you usually cannot get unlimited hotspot data. Cellular providers simply aren’t as generous when it comes to internet data, so the vast majority of hotspots come with relatively strict service plans.

But you still have some solid options when it comes to getting a hotspot data plan. The best data plans cost upwards of $50 per month for 40–100 GB of data. Some plans let you buy a smaller amount of data up front for a lower monthly price, saving you money if you use a hotspot only once in a while.

Our top mobile hotspot plan is T-Mobile’s 2GB plan. It gives you 2 GB of data for $10 a month. If you run out, you can get a “data pass” to buy more data. We like this one because it’s really affordable and gives you more flexibility, since you don’t have to commit to a bunch of data at a high price upfront.

You can get 50 GB of hotspot data from AT&T for $55 per month. And Verizon is no slouch on the hotspot front either, offering a range of hotspot plans with generous data options at competitive prices.
