Smartphones are naturally equipped with a mobile radio interface, otherwise telephony would not be possible either - and this makes it possible to use mobile Internet via LTE in almost all cases and, in some areas, even 5G.

Things are a bit different with notebooks - additional hardware is required here if it is not one of the few devices with a directly integrated cellular connection.

The keyboard and screen are a bit smaller, but the technology can compete with the large computers. All common application programs run on them, and optical drives are often still included.

Modem and cellular connection for laptops

For the connection to the network, the user usually needs additional accessories - apart from individual devices that come directly with an integrated LTE modem. A WLAN interface, on the other hand, which can be used to go online at hotspots, is now standard.

A relatively simple solution for owners of a laptop without an integrated SIM card slot are smartphones with an LTE / 5G modem, via which the data connection is established - if the smartphone supports this on the hardware and software side. This process is also known as tethering.

Mobile hotspots are alternatives to the smartphone as a modem. Mobile hotspots bring cell phones, tablets and laptops to the Internet via WLAN via cellular network.

Smartphones: Compact solution for mobile Internet access

If you only want to write e-mails while on the move and access some Internet content, you can simply surf directly via smartphone - these offer the simplest and most compact solution for full mobile Internet access. Access to the network is possible even with various feature phones (for example with the KaiOS operating system), although the use of the smaller displays and cell phone keyboards is of course only moderately convenient.

When you have the equipment, all you need is your Internet access and you're good to go. The user may no longer have to worry about entering the dial-in data - the smartphone does this automatically. If manual configuration is required, you will find the dial-in data for today's packet-switched access via LTE and 5G on our special overview page.

Tablets are trendy

There has been quite a hype about tablets for a while. The advantage of such devices: They are flat and, thanks to the touchscreen, can be operated easily with your finger. As a supplement, there are also real keyboards for some models, tablets are only of limited use for writing longer texts with the touchscreen keyboard. In particular, cheap tablets are currently more enlarged smartphones and less real computers - apart from exceptions, which are delivered with Windows operating systems or iPadOS, for example.

Tablets are quite well suited for surfing the Internet - you can scroll through the pages with a swipe of your finger, tapping the display zooms in and much more. You can find out everything about tablets in our tablet buying guide.
