The product earned by the current - relatively short - probably 5 star. Operation and commissioning is simple and the connection quality and data transfer performance to two different providers is the E5730 a lot better than an HP EliteBook notebook with integrated HSDPA + modem.
The response from Amazon for missing USB charger: also deserves kudos -> it was offered promptly credited as compensation. Why the product description is still wrong, understands only a manager of a US corporation ...
Huawei:
Dumber and ignorant it is hardly. This Mickey Mouse (technology-copy) Bude from China (see Wikipedia - very exciting) is unable to correct email address on the German side Huawei specify -> [email protected] -> Go to China and - the correct address is not announced by China .... here is you - if someone wants to get in touch in German or must: [email protected]
Neither the employees in China - even the employees in Germany to understand that the dealer (here was fortunately Amazon.com) something can do about a missing part of the published delivery of Huawei.
Huawei denied stubborn like a mantra on a solution to the problem caused by Huawei.
To date 05/22/2014 is still visible on the product home page of this dubious company that supplied a USB charger is included.
After some research I found an English manual, where the USB charger is cited as "optional" means therefore is clear Huawei never provides a USB charger, and the behavior of Huawei Germany and China is marginal - almost fraudulent.
Buying a Huawei product is thus relatively risky because there will never be a support of Huawei - the only hope is then that settlement via Amazon.com warranty.
