Hi. My girlfriend is in Mannheim for 6 weeks to learn German at the Goethe Institute. Knowing almost no German, though, she's a little lost. Right now she's trying to figure out the best option for calling back to the States. She's purchased a pre-paid cellphone, but it seems like she still needs a calling card to call back to the US. What's available, and what should she do? Should I just buy some and send them to her or is there an easier route?
Also, are there any good internet cafes or places with wireless access in Mannheim? She has access to a computer lab, but it's busy and their hours aren't the best.
Any other tips or places to visit would be welcome, as well.
