I need to install a hotspot in Germany, without fast wired access to the web. So I need to use some mobile provider, most likely with its own USB-modem for high speed access. I am a bit pessimistic to use a 3G miniPCI, because of compatibility.
Any recommendations, which provider/modem to use for a MT-board with USB ?

Provider does not matter, just the modem.
