All mobile phone options – full flexibility & cost control

With SIMon mobile you get a versatile mobile phone contract - and at the same time you retain all the freedom and full cost control. You have a whopping 15 GB of data volume available per month for surfing, gaming, chatting and streaming. If you need more data volume, you can get +5 GB or even +15 GB per month. Book additionally and surf with 20 or 30 GB. You can cancel the additional data volume at any time at the end of the month. Clean!

With the practical all-net flat rate, you can make calls and text messages to all German networks - and EU roaming is also available for free. If you are going to a non-EU country, you can simply book an additional option. In addition, you never have to worry about a cell phone bill that is too high again: no connection fees, no shipping costs, no contract with a term of several years, can be canceled monthly and paused for up to 3 months. Reconsider every month whether this tariff suits you and your everyday life.
