I guess people will have to talk others more as they was in the beginning. School kids, students will have go to the library to collect information for their project works and other things. It stop kids playing games on the mobile or tab and will be forced to get out of the house to play some games which will keep them fit. Peolpe will not get any news from around the world within seconds and will need to wait for the news channel or wait for the new paper.
The post office will become very active as there will be a lot of telegrams and letters. Mostly life will be different.
Or you can just look at North Korea or Afganistan without need to speculate

In 2006, Julien Pain, head of the Internet Desk at Reporters Without Borders, described North Korea as the world's worst Internet black hole in its list of the top 13 Internet enemies.
Internet access is not generally available in North Korea. Only some high-level officials are allowed to access the global internet. In some universities, a small number of strictly monitored computers are provided. Other citizens may only get access to the country's own intranet, called Kwangmyong. Foreigners can access the internet using the 3G phone network.
Internet access is restricted to regime elites and select university students. The state has created its own substitute "internet" but even this network is restricted to certain elite grade schools, select research institutions, universities, factories, and privileged individuals. Moreover, the intranet is filtered by the Korea Computer Center, which ensures that only information deemed acceptable by the government can be accessed through the network.
