I saw an article that said they were installing internet in all the immigration areas. I doubt they're doing that so people can go on Facebook and Twitter while they're waiting in line. If you arrive without an E-Ticket, you'll probably have to fill it out there.
They want to know where you're coming from, which airline you're flying on, how long you're staying and where. A lot of it will probably be used for marketing purposes. Way too time consuming to hand enter that data into a computer from a form. Much more efficient to have a passenger enter that online and have a computer spit out and sort what they're looking for.
At various government owned places, such as in public hospitals, government offices, even in certain parks; have part of the government created program
República Digital. This is available not just in major cities, but also in various towns and even in some villages. I'm not aware it's available in any campo (I know if anyone goes to Parque Duarte in Sajoma,
República Digital works on your smart phone and that's a town in the mountains out in the middle of nowhere). Basically is wifi and it is free, but it doesn't allow access to websites like Facebook, Instagram, Twitter and other social media places. It allows access to personal/company networks and email, so it can only be used for work related or very personal issues or even for school/university purposes. Anyone can access it and use it free of charge. At the very least you need is a smart phone or any other wifi enabled technology such as tablets or laptops (good luck taking out a laptop or tablet in public places and not attract attention).
In all likelihood
República Digital will be extended to the handful of international airports.
