Everyone wants to stay connected. There are emails and texts to read, videos to watch and games to play. Use your phone for these though and you're burning through megabytes and gigabytes of data. Wouldn't it be better if you could get on WiFi everywhere you go?
That's the idea behind mobile hotspot devices. They let you create a WiFi network, just like the one you have at home but portable. No more lingering over a cold coffee in Starbucks while you use their WiFi: just connect instantly wherever you are.
The subject of this article is mobile hotspot devices. More specifically, we're going to review eight of the best-selling such devices so you can decide which will suit you, your family or maybe your customers, best.
If you haven't already been through our other piece on this subject, “How to get WiFi in Your Car”, you might want to take a look before reading this. It provides a more general introduction to the why's and how's of in-car WiFi but without the individual product reviews. Here we'll quickly summarize the advantages before getting into the details of what to look for and why.

Phones are wonderful devices in many ways but they have some limitations too. Here's a list of ways in which mobile WiFi beats a cellular connection.
- Data caps. Unless you're on a costly unlimited plan there's a limit to how many hours of video and music you can download each month. WiFi overcomes that.
- Working on a big screen. Spreadsheets and graphics are just two examples of software products that are hard to use on a phone. When the boss emails that big file you want to be able to read it while you're on the road.
- Using a keyboard and mouse. Ditto to the above.
- Connect multiple devices simultaneously. Say you're on a family roadtrip and everyone wants to use their device: with a WiFi hotspot you can all get on the same network. The same applies to those awkward work trips colleagues are sometimes forced to make.
- Security. Public WiFi hotspots are vulnerable to attack. That might not be a concern if you're just checking Facebook but would you bank over a connection like that? A personal mobile hotspot is far more secure.
Check the settings on your phone and you'll probably see it has a “hotspot” function. This lets you set up a mobile WiFi network. It's a good option when you need to connect a few devices for a short period, but over longer periods it has some negatives.
- Drains the battery – phone must be plugged in to charge
- Uses your data plan
- Cellular service providers dislike “tethering” (using your phone as a hotspot,) because it sends a lot of data through their network. Even on an unlimited plan your provider may impose penalties or speed caps.
- Limit to how many devices can be connected. (Typically three to five.)
3G versus 4G – and what about 5G?
3G, 4G and in the near future, 5G, refer to cellular network speeds. This is relevant because mobile hotspot devices send and receive data over cellular networks. 4G is faster than 3G, and 5G promises to be faster still. When shopping for a device it's important to consider what speed you'll need.
The two drivers behind this are: the number of devices you expect to connect and what you'll be doing with them. If you're investing in a mobile hotspot purely to send and receive email while out of the office a 3G connection may be fast enough. Alternatively, if you want WiFi in a RV so a small brood of kids can all watch different movies at the same time you should definitely go for 4G. (And 5G will be even better when it becomes available.)
What to look for
Here we’ll go through the various features to consider when choosing a mobile hotspot device. Sections will address:
- Battery life and charging
- Ports on the device
- WiFi frequency
- Number of devices that can connect
One factor that’s hard to evaluate explicitly is range: it depends on many different variables. However, if you buy a device and find it doesn’t have the range you need you can add an antenna (providing your device has an antenna port.)
Your hotspot device needs to connect to a cellular network and so has a space for the kind of SIM card used in your phone. Devices are available both locked, (typically you'd get these through your phone provider,) and unlocked, allowing usage on any network with the appropriate SIM card.
Most reviewers consider Verizon to be best for coverage and speed, although many note that T-Mobile has good speed too. One factor you may consider is who you’re with now. It’s probably easier and cheaper to add another line than to start new service. That said, be sure to tell them what the line is for otherwise you will likely experience some data throttling.
Battery life and charging
This is often 8 to 15 hours, but can vary widely between devices, and how you use it. You may not get quite what the manufacturers claim. How big a factor this is depends on your anticipated usage. If you’re providing WiFi at your lakeside cabin long life might be important. If you just want a couple of hours while you’re in the car, maybe it’s not so significant.
All the mobile hotspots reviewed below are charged either through a USB port or a regular mains adapter. That means you will need to connect it to either a USB or 12V outlet in your car.
Ports on the device
Some provide USB-A outlets where you can charge a phone or tablet. You may also find other USB ports intended for external hard drives. Occasionally you’ll find an Ethernet port, which is useful for any devices that don’t have WiFi.
The other port to look for is what’s called a “TS9 external antenna port.” This will let you plug in an antenna for improved range. You will need to buy it separately though.
WiFi networks all work at 2.4GHz. Some devices however also use the 5.0GHz band. The latter can be faster and more reliable as it’s typically less congested and has more channels. However, it does have shorter range than the 2.4GHz band. Ideally, get a device that works on both simultaneously.
Mobile hotspot devices all need a little bit of set-up prior to first use. This is easier if there’s a display that shows you what the device is doing, and easier still if it’s a touchscreen. At a minimum, you want one that displays the network name and your data usage.
Number of devices that can connect?
As with battery life, the importance you place on this depends on how you expect to use it. A family on a camping trip could easily be connecting eight or 12 devices while the lone road warrior might just have a laptop, tablet and phone.
Older and less expensive devices may allow five to 10 connections but pay more money and you can go to 15 devices or maybe more. Note though that you might not get 4G speeds on every device.
