About the delivery need not say much, as always very fast!
Some key data from the E5151;
somewhat bulky but visually noble, connection and set up went very quickly, connection with the new modem twice as fast in Down / upload (with the SIM card), Ethernet connection is simple (plug in and you can start surfing, and anyone can log in with the PW from E5151).
But so far not found anything bad, will post an addendum to my US holiday, because that's why I thought it would also be bought (open holidays modem with Ethernet connection!)
