What is a Hotspot? How to Turn Your Phone into a Wi-Fi Router
You are sitting on the train, you want to work on your laptop, but the public Wi-Fi is down once again. Or you are in the park with friends and someone has already used up their data volume. Salvation in such situations is often just a click away: your smartphone's personal hotspot. But what exactly is a hotspot? How does it work, and are there any extra costs involved? In this article, we clarify all your questions and show you how to turn your phone into a mobile Wi-Fi router in a matter of seconds.
Simply Explained: What Exactly Does Hotspot Mean?
When asking "what is a hotspot?", the answer is actually quite simple. A hotspot is basically an access point to the internet. While public hotspots (such as in cafés, airports, or train stations) are provided by permanently installed routers, the so-called "personal hotspot" works directly via your smartphone.
Your phone receives the mobile internet signal (e.g., 4G or 5G) from your provider and converts it into a local Wi-Fi signal. Other devices like laptops, tablets, or your friends' phones can then easily connect to this Wi-Fi network. Your smartphone therefore acts as a bridge between the mobile network and the target devices that currently need Wi-Fi.
How Do I Activate the Personal Hotspot on My Phone?
Setting up a hotspot is child's play and takes only a few seconds on both iPhones and Android devices.
For Apple (iOS):
- Open "Settings".
- Tap "Personal Hotspot".
- Switch on the toggle next to "Allow Others to Join".
- Directly below, you will see the Wi-Fi password that others need to enter in order to connect.
For Android (e.g., Samsung, Google Pixel):
- Go to "Settings".
- Choose "Network & Internet" or "Connections".
- Tap "Hotspot and Tethering" and then "Wi-Fi Hotspot".
- Turn it on and, if required, set the name of your network and the password.
As soon as it is activated, your phone will appear in the list of available Wi-Fi networks on other devices, just like your router at home.
Does a Hotspot Cost Extra Data Volume? (The Cost Trap)
Caution is advised here! While a hotspot itself does not incur extra fees from your provider, the devices connected to it consume the data volume of your mobile plan.
Since laptops and tablets often seamlessly download larger amounts of data in the background (e.g., system updates) or automatically display websites in the data-heavy desktop version, your monthly data limit can be used up incredibly fast. If you have a plan with limited volume, sharing your connection quickly becomes a cost trap. Anyone who uses a hotspot regularly should therefore absolutely have a plan with unlimited internet.
Security: What to Look Out for with Your Wi-Fi Hotspot
When you share your internet with others, you shouldn't neglect security. Never leave your access open (i.e., without a password). Anyone nearby could otherwise connect to your phone, surf at your expense, and, in the worst-case scenario, even access your data.
Always use a secure password with the WPA2 or WPA3 encryption method (this is usually set automatically on modern smartphones). You should also turn the feature off in the settings when you no longer need it. This not only protects you from uninvited guests, but also spares your phone battery, which drains noticeably faster when the hotspot is activated.
