Just watch TV - no data plan or wifi connection required. Aerial TV works by picking up digital TV channels off the air with a regular TV antenna.
You will need a low cost USB TV tuner. You can grab one online for less than $10. Make sure to get an RTL2832 tuner with the R820T chip. When it arrives, just connect the provided antenna and start watching. You may need a USB OTG cable to plug the tuner in your Android device. USB OTG cables are inexpensive and easy to find.
Note that your Android device must support USB OTG. If unsure, do a quick search online or consult your Android device manual. Also check that there is DVB-T service in your local area by doing a quick search online. Aerial TV needs to be able to pick up DVB-T signal. For best results use an outdoor aerial.
You get free unlimited access to radio forever. You also get to watch all TV channels and experience all features of Aerial TV during the trial period for free. After the trial period ends you can make a one-off purchase and watch as much TV as you want. Remember: you can keep listening to radio even if the trial has ended!

Q: Can I watch DVB-T2? A: If your country has DVB-T2 broadcasts (such as Freeview HD in UK) you will need a DVB-T2 compatible receiver dongle such as R828D. Aerial TV will pick up DVB-T2 broadcast with most R828D dongles.
