All-Network Flat-Rate Tariffs

Internet use by Smartphone

All tariffs offer Telephone and SMS flat rate to all German networks. Few tariffs offer a real Data flat rate.

Data Volume 6 to 120 GB (SIM-only Tariffs)

No real data flat rate below EUR 50 per month

Telekom MagentaMobil S

39.95 EUR/month: 6 GB data volume with LTE Max up to 300 MBit/s download, up to 50 MBit/s upload. Afterwards throttling to 64 KBit/s for download, 16 KBit/s for upload. WLAN hotspot flat rate. EU roaming incl. Switzerland. Max. 10 additional SIM cards with the same phone number (MultiSIM) for use e.g. in a tablet PC – 4.95 EUR/month each.


Savings tip for these two Telekom tariffs: if no WLAN is available and the data volume of the tariff is to be spared or used up, I recommend booking a DayFlat unlimited (24 h unlimited high-speed volume for 5.95 EUR).

… or do you need more data volume only stationary or on the tablet PC? Then take a look at these data tariffs …


Icon Light bulb: here is a tip!Although the above-mentioned smartphone tariffs are more expensive than those of resellers (providers such as mobilcom-debitel, Drillisch etc.), I recommend concluding a contract directly with the network operator (i.e. only Telekom, Vodafone or Telefónica). To put it diplomatically: it is less stressful. Winking Smiley


Icon Light bulb as a reference for the following practical tip!Recommended distribution channel: retail shop. There can be very attractive promotions online for a limited time. For working people, however, these are usually not usable if SIM cards are only handed over personally for security reasons (Deutsche Telekom, maybe also Vodafone). Either you are not met by the delivery person or the delivery person does not come to your door at all. Online offers can usually also be used as an «offline regular customer» and you can book yourself in the customer centre (web portal) of the network operator. It is often better to first contact the mobile phone retailer of your choice locally/via the Internet. They may be able to make you a better offer!
It doesn't cost anything to ask, but it can be worth it!

Icon Light bulb as a reference for the following practical tip!Watch out! All work on a commission basis and therefore not everyone gives priority to customer requests!

If you do not trust your local dealer, you should buy online and get further opinions first. Some online forums are very suitable for this!
