One of the first things to arrange after arriving in a new country is a local SIM card. As a foreigner, you might be especially interested in the offer of simquadrat.
simquadrat offers you a SIM card with a German landline number. This is very convenient if people call you from outside Germany because the rates for calling a landline number are usually just a fraction of the ones for calling a mobile number. 
Besides, simquadrat’s rates are not really higher than on other prepaid cards:
- 9 Eurocent/min for calls to Germany (landline or mobile)
- 9 Eurocent for SMS to Germany
- 10 EUR for 1GB Internet per month
What’s even better: When being abroad in the EU, no roaming costs apply for the first 30 days (excl. Internet). This means: people can call your German number without you paying anything during the call. And you can keep calling German numbers for 9 Eurocent.
Here is the site to order the simquadrat SIM card.
- Take for instance Skype: Calling a German landline number costs you 0.50 Eurocent, a mobile number 5.2 Eurocent per minute.
