I believe the T-Mobile stick is the UMG-181 made by Huawei Technologies. If I were you, I'd check with support@mofienetwork.com and ask if there are certain settings that you need to enter to make it work properly with the T-Mobile network. The default settings in the router may or may not work properly with the router. -- Rogers ZTE MF636 stick, MoFi3G router, Apple Intel iMac, OSX 10.6
I contacted support and they advised me it should be supported in several weeks. I will wait as the T-mobile stick is really a fast connection and excellent internet.
