Web Sessions

Mobile Internet usage without a contract

Vodafone limits the allowance per session to 50 MB during roaming. After exceeding this volume the session finishes and usere are automatically redirected to the Vodafone captive portal, where a new Websession can be activated.

How to activate
To make use of the WebSessions tariffs you must set your device to use "event.vodafone.de" as access point (APN). Connections through other access points will be billed differently. Even before starting a WebSession you can browse the Vodafone [www.vodafone.de/ website ] free of charge and so test bandwidth and connection stability before paying. In order to test downstream bandwidth you can download [www.vodafone.de/business/hilfe-support/dashboard-software-fuer-windows.html Vodafone's dashboard (~ 75MB)]

How to top up
Pay directly by credit card

Paying WebSessions directly by credit card is not counted as a top-up and so will not prolong SIM valitidy. But you can keep your SIM active anyway: Just call 12007 from your Vodafone SIM at least once in 12 months and press 1 after the prompt. This will keep your SIM active for another 12 months even without topping it up the classical way.

At local shops

Therefore you may buy top-up vouchers (so-called "Vodafone CallNow"), which are available in many supermarkets, gas stations, etc. Aftr you have gotten a top-up voucher, which basilcy is a 13-15 digit number, it can be recharged either online via the Websession captive portal (click on "Redeem of Vodafone CallNows") or by using USSD commands (see below). You can also check the current credit either on the captive portal or by USSD. Note: You can connect and reach the Vodafone captive portal free of charge at any time.
