Subject: Greg Belaus Blog Post - Google Nexus 7 Brings Best in Class Picture Quality to AT&T Customers

This email is directed to Greg Belaus or the current Consumerist at AT&T.

I am one of the lucky few that have purchased a Google Nexus 7 LTE and am a current AT&T customer with 3 Smart Phone devices and 3 Tablets, all with expensive Data Plans through AT&T.

My concern (before I return the Google Nexus 7 LTE) is why the Hotspot and Tether options disappear when an AT&T SIM Card is plugged in. I have the 5GB DataConnect Tablet plan that includes these features. When I setup the device (without the SIM Card installed) the Hotspot and Tethering shows up in my settings. As soon as I plug in the AT&T SIM Card, they disappear, never to be seen again unless I do a factory restore. Only then do I have the options back, until I plug in my SIM Card again.

I have contacted Technical Support and they have verified that my device is provisioned properly and that I have Tethering and HotSpot included in my 5GB Data Plan, but are unable to restore this functionality.

I have posted this issue on XDA Developers, Android Central, and Talk Android, and will keep reaching out until I get a clear answer (I almost CC'd randall.stephenson at att.com as well).

Please investigate why this is disabled, and if it not something that I will be able to use (since I am paying for the feature), I will need to determine my best course of action to terminate my Tablet contract as it appears to me that AT&T is blocking features that I am paying for in my plan.

9/18 Received an email from attcustomercare at att.com with the following Case ref:_00DE0czFk._500E0703wB:ref that it was being looked into.

9/19 Contacted Google Nexus Support by Phone. Was informed that this was being escalated by Google Support. Case 5-5927000001711

What needs to be determined is if this is an accident or intentional. As I am paying for Tethering and Hotspot, I have a serious issue with this so far and it seems that there would be nothing AT&T can do to my device to get it restored. Short of Google correcting the issue and issuing an OTA Update, but this would mean that AT&T will need to work with Google to fix this

Unless this issue gets exposure from some people calling in or from Android websites, I am sure this will be a low priority
