In my Lebara under "Settings", you will find various cost checking options. 

090x numbers: You can activate and also deactivate call barring free of charge directly in "Settings" for each of your individual rates. Two call barring sets are available:

• Call barring set 0906x: This block set blocks calls to adult entertainment lines. You can continue to access helplines or transportation schedules on 0900 or 0901 numbers.
• Call barring set 090x: With this call barring set, all calls to 090x numbers are generally blocked. Calls to SBB timetable information, televoting and general entertainment, such as horoscopes, chat forums, games, competitions, surveys, etc. are now no longer possible.

By the way, in the Lebara Switzerland app you always have an overview of your call barring settings when you are on the go.

Premium SMS: When this option is deactivated, premium rate numbers (hotlines or teleshops, etc.) can no longer be used. You also have the option of changing the settings directly in my Lebara.

• To switch premium SMS/MMS on: Text PREMIUM SMS START to 255
• To switch premium SMS/MMS off: Text PREMIUM SMS STOP to 255

Mobile Internet: If you deactivate mobile data, you can only surf the Internet over WLAN.

Use abroad: After deactivation, the use of mobile data, SMS/MMS, and calls will be blocked.

Data roaming in excess of options and included data: By deactivating, you will avoid paying for mobile data on the Internet once you have used up the options and included data you have signed up for. You can continue to use this as before.

Tip: To save costs, take advantage of our attractive add-on packages. These can be found in the "Roaming Cockpit" in my Lebara.
