How to choose your unlimited 4G key

Having Internet access everywhere is crucial to surfing and working. With that in mind, you need the right unlimited 4G key. To find what you need, here are the criteria to consider.

#1 - Transfer speed

The 4G key is one of the most traditional ways to access the Internet. The transfer speed corresponds to the speed of flow in sending or upstream (upload) and in downloading or downstream (download). In the case of a 4G key, we talk about very high speed which can reach more than 150 Mbps downstream and 50 Mbps upstream.

#2 - Have access to the Internet via a 4G key

Before buying a 4G key, it is important to know that it is not the key that provides access to mobile Internet, but the subscribed package. Thus, it is also important to know in advance which package suits you best. To have a connection via 4G key, you need to meet 3 main conditions: having a 4G key, subscribing to a package and having 4G coverage.

#3 - The power level

The power level is the ability that the 4G router will have to communicate with the relay antenna for 4G. In other words, it is the power ratio in decibels. A value of 20 DBM offers a X100 improvement in the signal. Although not always noted on the technical specifications, this information is one of the first to know.

#4 - Available packages

In order to

enjoy the benefits of an unlimited 4G key, you must, not only purchase the key and be located in an area covered by 4G, but also subscribe to one of the packages available from mobile operators. If the packages without commitment allow you to connect for a limited time, the packages with commitment are intended for those who need a connection on the long term.

#5 - Compatibility

The operators have made available new models of compatible keys by launching their 4G network. Each mobile technology indeed requires compatible hardware. It is according to this compatibility that 4G keys are classified into 2 categories: 4G keys connected via USB and 4G modem models.

What are the advantages of a 4G key and how to benefit from it?

Plugged into a USB port of a computer, the 4G key or "router" is a tool offering Internet access that is powered by the device that hosts it. It works thanks to a SIM card that allows to connect to the 4G network to have a very high speed Internet access. More briefly, it is a mobile device allowing access to the Internet via the mobile network of an operator.

Operators offer the possibility to stay connected to the Internet anywhere thanks to 4G keys. Moreover, the connection will not be dependent on the battery of another device. Easy to carry, they offer another advantage by their small size. They have the ability to capture a mobile network and transfer it simultaneously to several compatible devices. In addition, they offer the possibility to connect without using the data envelope of a mobile package.

You can benefit from these advantages by taking out a subscription with the operator of your choice. A SIM card with a 4G package must be inserted in the key. Rechargeable every month or every day, this package includes a limited data envelope that can generally be used from metropolitan France, the DOM and the European Union.

Frequency bands

Attention to frequency bands. 4G is based on radio waves and frequencies differ from country to country. There is no guarantee that the 4G key you buy in the UK will work in another country.

Unlimited 4G key or 4G box?

The unlimited 4G key

The 4G stick is a mobile device that allows people on the move to stay connected. It also benefits people who work from home. Unlike connection sharing, it can be used for several hours without draining your phone battery. On the other hand, it is necessary to subscribe to a package apart from the price of the key.

The 4G box

Unlike the 4G key, the 4G box is a real box that cannot be transported and can only be used by people living in white areas with good 4G coverage. Certain eligibility conditions must also be met in order to enjoy its benefits.


The choice depends largely on the users. The 4G key and the 4G Box both offer a high performance and very high speed internet access. However, the 4G key is more recommended for people who move around regularly but need to stay connected.

Why buy a 4G unlimited key?

To access the internet anywhere

The 4G Unlimited Stick lets you access the internet wherever you go as long as the location has 4G network coverage. If you work outside the office, this is a convenient way to get online at any time if you can't get a Wi-Fi network, which is a real advantage in terms of mobility. Above all, it's a must-have for anyone on the move, whether it's for business or for vacation. Basically, it's a device that gives you access to many options. You no longer have to connect your mobile device or computer with an Ethernet cable.

For its ease of use

A 4G unlimited key has the advantage of being easy to use. All you have to do is plug it into a USB port on your PC or tablet. In addition, it is compatible with any operating system and does not require the use of a hotspot or a modem.

To enjoy a comfortable browsing experience

The 4G key allows you to benefit from a flow evaluated around 150 Mbits/s. You are guaranteed to have a very high download speed. The loading of pages is also faster. It is intended to provide a connection for a single device. You can also use your key even outside the big cities as some rural areas are covered by a 4G network.

For its discretion

Compared to the router which takes up more space, the 4G key is not bulky. So you don't need extra space to use it. After using it, you can easily put it in your pocket or put it back in its box and slip it into your bag.

For its practicality

When you use your smartphone for connection sharing, the battery gets used up very quickly. With a 4G dongle, you get a Wi-Fi connection without having to use your smartphone.

The best unlimited 4G dongle depends on your needs and your budget. Read our buying guide to find out which products are the best.

What is a 4G / 3G key?

A 4G (or 3G) key is similar to a USB key that allows its users to benefit from an internet connection wherever they are (except in mobile white zones) and whenever they want. Wireless, the 3G / 4G key is an interesting solution for all people wishing to access the Internet and who do not have a WiFi hotspot nearby.

To start using your 4G key, there is no installation as such. All you have to do is insert the SIM card supplied with the 4G key or hotspot, plug the 4G key into one of your device's USB ports or connect it to the Wi-Fi network, and then confirm Internet access.

How does a 4G key work?

A 3G or 4G key fits into one of your computer's USB ports. It looks like a classic USB key and differs only in its function: the key acts as a small portable modem and picks up the 3G or 4G network of the mobile phone operator on which it depends.

Is there a 4G Free key offer?

To date, there is no key 4G offer. The Free unlimited mobile package has a very substantial 4G envelope, both in the UK and abroad. Using a shared connection can therefore be an interesting alternative.
