Data Volume needed only stationary or on a Tablet Computer?

Then take a look at these data tariffs …

Tip: Although the above-mentioned smartphone tariffs are more expensive than those of resellers (discounters like mobilcom-debitel, Drillisch etc.), I highly recommend concluding a contract directly with a mobile network carrier (Telekom, Telefónica o2 or Vodafone). To put it diplomatically: it is less stressful.

Recommended distribution channel: retail shop. There can be very attractive promotions online for a limited time. Unattainable for working people if SIM cards are only handed over personally for security reasons (Telekom, maybe also Vodafone). You will not be met by the delivery person or "he doesn't like to deliver".
Online offers can usually also be used as an "offline regular customer" and you can book yourself in the customer centre 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!
