Germany mobile contract consideration. Options are:

Telekom 10GB: 15.25/mo
Vodafone 18GB: 13.66€/mo
Vodafone Unlimited: 19.57€/mo

Telekom better reception at train station; Vodafone has reception at my grandma. But I do have a vodafone datacard so I could switch on demand if needed. Best of both worlds? Hmm.
