The price is probably to undercut only by Germany SIM itself. Real the cheapest I've seen. Sometimes there are even for only 2.95 EUR - partially then 50/50/200. MM according to ideal for the young, the surf or the what's Appen can not leave. The 100 SMS are many too much, the 100 min. Really well. 300 MB are in Wi-Fi usage sufficiently at home - 200 could zwacken ever. O2 is (at least for us) Nationwide coverage - with no problems. Difference even on a school trip in the Eifel for D-network is not noticeable. iPhone card no problem. Manageable costs continue surfing, possible if volume depleted. Also raise a little. Desired numbers possible a lot of money against (relatively). Highly recommended!
