No problem provided its a Huawei dongle like Virgin Mobile's.
Go to Settings, System Information and click the Help tab. Click on the link to Acer's support site, then click on the 8.9" model. Select your colour - ignore the right side of the next screen and look at the faint text at the bottom left of the pretty picture. Move the cursor over this area and select 'Drivers & Support'. A screen headed updates appears - select the connect option and find 'Macles' near the top of the list. Follow the on screen instructions to download, unzip and run this file.
After a reboot you will have a new application called 'Mobile Partner' in your extended Connect menu. Open this and set up a profile for your dongle from Tools Options. The quick way to get the info you need is to copy it from the equivalent Windows profile.
Save your new profile, plug the dongle. In Mobile Partner select the Connections tab and click the connect button. In a few seconds your 3G connection will be up and running!
