Paper license
You get a printed license and physical tags in the mail. At the kill you fill out, date, notch, and attach the paper tag immediately. No phone or signal needed in the field.
Licenses / Tags & digital
Some animals must be tagged the instant you take them, and Texas now sells fully digital licenses - which changes how tagging works. This is where the rules trip people up, so read it before opening day.

The catch
Here's the catch with going digital: a digital-only license comes with NO printed paper tags. To legally tag a deer, turkey, or an oversized red drum or spotted seatrout, you need EITHER a physical (paper) license with its printed tags OR the Texas Hunt & Fish app to tag and log the animal on the spot. Don't assume the app and a paper license are interchangeable - pick one system and know how it works before you hunt.
One more wrinkle: One more wrinkle for digital license holders: when you tag a deer or turkey through the app, you must still attach a physical note - on durable material, with the app's confirmation number - to the carcass. (For red drum and spotted seatrout, the app report alone is enough; no physical tag needs to be attached.)

Nothing is mailed. You carry the license on your phone and tag through the Texas Hunt & Fish app the moment you take the animal. Great if you always have your phone - but learn the deer/turkey 'attach a note with the confirmation number' rule first.
Official sources
Tagging rules, harvest reporting, and the paper-vs-digital details all come from Texas Parks & Wildlife. The Texas Hunt & Fish app is TPWD's official tool for digital licenses and tagging.
Caution: Tagging rules, reporting deadlines, and the mandatory-reporting county list change. The official TPWD pages are the final word - confirm before you hunt.
