Mobile Hotspot vs. Phone Tethering: What’s the Difference?

Phone tethering is a way to use your smartphone to get internet access for laptops and tablets while you’re away from home. Tethering is the act of connecting via Bluetooth, Wi-Fi, or a USB cable, and your phone’s hotspot is often referred to as a personal hotspot. A mobile hotspot is another way to connect tablets and laptops, but it requires a separate device and can connect a lot more device at once.

Either way, you use mobile data from a cell phone provider to set up portable Wi-Fi. So how are these methods different, exactly? And which option is better for your needs? Read on for a full explanation.

Tethering explained—a hotspot on your smartphone

Phone tethering means making a connection (or “tether”) from your phone to a separate internet-capable device, like a laptop. In doing so, you use mobile data to set up an internet connection for the laptop.

You can tether devices using Bluetooth, a USB cable, or a Wi-Fi signal.

How tethering works

  1. Your phone grabs data from a cellular tower.
  2. The phone’s personal hotspot uses that data to set up an internet signal.
  3. Your laptop or tablet picks up that internet signal from your phone, either through a USB cable, Bluetooth tethering, or Wi-Fi.
  4. Your device gets internet access when you select the Wi-Fi account and enter the password.

Phone tethering is a simple, secure, and cost-effective way to connect to the internet when you’re out and about. As long as your phone plan comes with hotspot data, then you can switch on your phone’s hotspot and use it for Wi-Fi anywhere you get cell service.

Most phones nowadays have built-in hotspots that allow for phone tethering, and many phone plans come with hotspot data you can use expressly for this purpose. If your cellular carrier doesn’t automatically give you hotspot data, you can usually add it to your plan for an affordable price.

Phone tethering pros and cons

Phone tethering is easy and fast, but it’s only good for short-term use. You’re limited with how much data you can use and how many devices you can connect, and the personal hotspot drains your phone’s battery when you use it for an extended period.


  • Easy setup
  • Affordable data
  • Accessibility anywhere with cell service


  • Limited features
  • Strict data caps

Mobile hotspots explained—standalone devices with added features

A mobile hotspot is a standalone device that works the same as a phone’s hotspot, letting you set up a Wi-Fi connection for laptops, tablets, and other devices using cellular data.

However, a mobile hotspot can do a lot more than a phone hotspot can. Some come with security features like firewalls and guest networks. And newer 5G hotspots also have up-to-date Wi-Fi standards that make it easier to support a large number of devices at the same time. Better yet, hotspots usually have better radios (to receive cellular signal) and better antennas than smartphones do. meaning better connectivity and faster speeds throughout the day.

How a hotspot works

  1. The hotspot grabs data from a cellular tower.
  2. The hotspot uses that data to set up a Wi-Fi signal.
  3. Your laptop or tablet picks up the Wi-Fi signal from the hotspot.
  4. You select the Wi-Fi account and enter the password to access the Wi-Fi network.

Using a mobile hotspot is just as straightforward as using your phone, but it comes with added expenses. On top of buying the actual hotspot device, you also have to invest in a hotspot data plan from a cellular carrier. But the extra investment nets you more data, greater flexibility, and an extra backup option when you need portable Wi-Fi while traveling.

Mobile hotspot pros and cons

A mobile hotspot is a significant upgrade from your phone’s hotspot, but not everyone needs one. Aim to get a mobile hotspot if you spend a significant amount of time away from the home or office and need a reliable way to get Wi-Fi when fixed broadband isn’t available. Hotspots are also ideal for school groups and teams of employees on work trips.

If you don’t have heavy-duty hotspot needs, you’re probably just fine using phone tethering to get some Wi-Fi every once in a while.


  • Connectivity for 32 or more devices, depending on hotspot
  • Consistent performance with Wi-Fi 6 on 5G devices
  • Affordable rates for data plans


  • Added expense for the device and data plan
  • No totally unlimited data plans
  • Location-dependent speed and quality

What’s better for you: Phone tethering or a mobile hotspot?

Stick to phone tethering if you only need portable Wi-Fi only once in a while. Your phone’s personal hotspot doesn’t have a whole lot of firepower or features, but it’s cheap and easy to use.

You’re better off upgrading to a mobile hotspot if you regularly go on long trips or regularly share your hotspot with a group of friends, classmates, or coworkers.
