I bought the CDMA SIM and Card for my computer, works fine, connects fine, =
but very slow. At first it was nice and pulled up pages and email very qui=
ckly, but over a few uses it slowed to a dial up speed. However, it is gre=
at to have if you are on the move and especially in areas where there is no=
wireless.<br /><br />One other use we are testing in our office is for a f=
ail over internet connection on our servers, we even have some clients usin=
g it on their dev servers to test SMS applications. Our engineer contacted=
the vendor and the huawei card though doesn't support Linux. I will have =
him read David's link<br /><br />Sorry also for missing the last meeting, I=
was quite sick and had my MBA class that week which I needed to be rested =
for, not too mention prepare for. I look forward to sharing you our experi=
ence in testing the CDMA technology. I will also try to post the contact d=
etails to our vendor<br /><br />Kind Regards,<br /><br />Michael Iannini<br=
/>President, BLUG<br /><br /><blockquote style=3D"border-left: 2px solid r=
