Thank you! I may have figured this out. I logged into my Blau.de
account. They asked for brand, and model #. The also wanted to know if I
wanted the settings for WAP, Internet or MMS. Here's where I wasn't sure: I
said WAP. Sure enough, they sent as text message with the settings, I hit
the install button, used the security pin they sent me and all seemed to go as it was supposed to.
The only thing I'm not sure of is if I asked for the right settings for my purposes. I'm still not sure if I should have asked for WAP or Internet
Finally, I'm going to be in Germany for most of the time; however I will be spending a day or two in Prague. I know I can make calls from Prague using the Blau sim but will I also be able to check data. I know it will be expensive, but it seems to make more sense that starting with a Czech sim card for such a short period of time. And, I'm sure it will be much less expensive than trying to use my iPhone.
