One handy feature on our Windows Phone devices is Internet Sharing. It allows you to share your cellular data connection over Wi-fi with other devices (laptop, tablet, etc.).
The bad thing is that carriers usually charge you for this service or limit the number of devices that can be tethered (which make no sense seeing that it's your data). We've been tipped that AT&T has made a change to the guest or device limit they impose on their Internet Sharing settings.
Apparently, at some recent point in time, AT&T expanded the number of guests or devices you can share data services with from five to eight. We aren't sure if you have to actually sign up for the service to see the increase in guests or if this is a gradual roll-out type of change.
My Lumia 920 is still showing a limit of five guests but then again, I'm not signed up for the service. Let us know in the comments if your seeing the changes on your AT&T Windows Phone or if you're on another carrier you're seeing the changes.
Thanks, Kai, for the tip and screen shots!
