There IS a setting for LTE on a 2013 Nexus7 (1B32-4G). I just found it where you set up the Access Point Name (APN). Just go searching. I was surprised to find it. You have to click on a lot of selections to get to it in Settings then at the bottom of the first section called Wireless & Networks click on More. Click on Mobile Networks,then you will see Mobile Network Settings. in that menu list select Access Point Names (APN), you should see your network carrier such as "T-Mobile US" & under it mine says "epc.tmobile.com" that was already set up at a T-Mobile store when I bought my SIM card & registered. Then click on the dot to the far right to select your carrier so that the dot turns blue. Click on the name of your carrier on the left side of the screen, & on the new menu list, which is called Edit Access Point, scroll down towards bottom, BEFORE you edit or add anything, and click/select "BEARER". In that menu list, click & select the choice LTE. It may have been selected as Unspecified at first. Press the "Go Back" button, & as soon as you complete that the rest of the list of items in field called "Edit Access Points" fills in automatically for what you need, including the Name field, which in my case says "T-Mobile US".Close all screens as you're done. Now it's a matter of finding out if the right "bands" correspond to get the right reception. My own Preferred Network selections are limited to 2G &3G, even though it says "4G" on the label with the model name. That's another issue I'm taking up with ASUS right now as two supervisors told me that my model number is 3G/2G, but they also say that ASUS won't take care of the matter by giving me an actual 4G tablet which is what I paid for on amazon.com. Even though I now have the LTE setting corrected, it still says HSPA in Settings>About Tablet>Network Type, which I read is only 3G. I'm still baffled.
