Finding a HotSpot area

Check your intended surfing location at the T-Mobile hotspot locator.

Make sure, you are in a hotspot area by either looking out for the logo (red dot with a red circle around it) or ask someone around who should know.

Configuring the Hardware

Remove all unnecessary communication cards from the laptop (i.e., GPRS/UMTS cards, bluetooth connectors, ...) to reduce the chance of failure.


Depending on the laptop type, this would either be a small slider, probably at the side or back, or a softkey combination, e.g. Fn-F2. Look out for an icon resembling a radio tower with emitting waves.

Selecting the Network

A notice window will pop up at the taskbar area telling that wireless LAN(s) is/are available. If not connected by default, open the installed WLAN manager software (typically by double-clicking the WLAN taskbar icon), scan for networks, and connect (typically by double-clicking) to the network "T-Mobile_T-Com".

After a few seconds, the network will be connected.

Logging in to the Network

Open up a browser and enter just any valid URL, e.g. You'll be redirected to the T-Mobile WLAN HotSpot landing page (only available from the HotSpot network).

There, either enter your "web'n'walk" credentials, or use the credit card login.

After successful authentication, you'll receive a welcome screen showing the online time.
