Recommended rates

The tariff ALL-IN 50 is ideal for infrequent / means users of smartphones.
The free choice of O2 or Vodafone should be something for everyone, because these are finally the two best mobile networks in Germany.

I'm a little Telefonierer and an even-less-SMS-Schreiber, the 50 min / SMS rich loose me.
Should I unexpectedly times longer to make calls, are 0.09 per minute / SMS a fair price.

200MB surfing enough for me also because I mostly used for information in writing (bus, weather, news) and therefore hardly consume data my smartphones.
Should we even exceed the 200MB, you pay no additional costs, but may continue at any time on the Internet, but with reduced speed.
Also no problem, enough for news, weather, Wikipedia, and Co..

Note should be, that this is not a conventional prepaid card, but so-called. Postpaid.
This means the bill is similar to a mobile phone contract debited monthly.
I recommend everyone who called. To be activated third-party lock through the Customer Service (free) to prevent accidentally any expensive subscriptions are completed.

If one considers that the collective is all-in 50 but highly recommended.
Similar offers in the two outstanding O2 and Vodafone networks is rarely found.

Through the current Amazon mobile offer even saves you the hassle of charge for the SIM card. What more do you want?

For excess or frequent users there are of course other tariffs, "ALL-IN 100" with 100 free-Min. / SMS for 9.95 and a complete All-Net-Flatrate for only 24.90.
