All mobile options – full flexibility & cost control

With SIMon mobile, you get a versatile mobile contract – while maintaining complete freedom and full cost control. You have a generous 20 GB of data available every month for surfing, gaming, chatting, and streaming. Should you need more data, you can add more monthly and surf at speeds of up to 150 Mbps. You can cancel the additional data allowance at any time at the end of the month. Perfect!

With the convenient all-network flat rate, you can make calls and send texts to all German networks – and EU roaming is included free of charge. If you're traveling outside the EU, you can simply add an extra option. Plus, you'll never have to worry about an excessively high mobile bill again: no activation fees, no shipping costs, no long-term contract, monthly cancellation option, and the ability to pause for up to 3 months. Reconsider each month whether this plan suits you and your daily routine.

Keep a perfect overview with the app

Register quickly and easily for the "My SIMon" customer portal. In your personal area, you can easily check your data usage and remaining data allowance at any time. If you need more, you can add a suitable data option. For complete cost control, you can always see your current expenses in the app.

Keep track of your current contract details and information in the app. If you ever need to edit your personal contract information, such as your IBAN, you can do that too.

If you want to transfer your phone number to SIMon mobile later, you can easily initiate the porting process in your customer portal.

If you need a replacement SIM card, want to switch to an eSIM, or need to block your current SIM, you can do it all in the app.

Need a break? No problem! You can easily pause your contract for up to 3 months in your SIMon mobile app. Convenient!
