Last year I went on a Disney Cruise. And I found that Disney Cruises offer a pretty good deal on WiFi. And I just wanted to read my emails. 100MB appeared to be more than enough. So on the third day, I decided to go for that plan. Before I did that, I disabled as many applications as I could, so as not to use up my 100 MB. I disabled all my apps: WhatsApp, Life 360, backup, Messenger+, and as many as I could think of . But the 100 MB were used up in about 10 minutes. And I didn't even get that many emails. Thinking back on what else I should have disabled, I thought about updates, GPS, Waze, and probably others. But I'm now planning a new Cruise, and I'm not sure if that's enough. So the question is, what should I disable? Keep in mind, I would like to stay under the 100 MB limit, and all I want to download is email.
