It all works beautifully. GSM is not for country folks, but in cities where GSM service is available, it works very well. The modem protrudes slightly above the top of the Visor and is not quite flush with the back surface of the computer. The Visor hard cover will still attach to the front, but will not store on the rear. Surfing the Web is a bit slow, but that is not the modem's fault.
Email is just like hardwire - fast, and problem free.
I have tried other wireless solutions for the Visor and I like this the best so far. No crashes, easy plug and play, in short, a non nonsense winner. Copyright 2001 INT Media Group, Incorporated All Rights Reserved.
