My idea is that Huawei forgotten that there has a product named B593s-22 because there are no doc, no firmware upgrade and no info on the website for this expensive 4G router I bought 1 year ago. And now the app said every times that I need to upgrade the app to support this router. I preferred the old app has beautiful and functional, with this new version its complicate to manually cut the 3G connection and to know if the connection is off or not. It would be great if routers support time contract, to see time elapsed.
