The big thing about a phone call is that you might not want help. If the characters are anything other then say teenagers at summer camp, then calling for help is not at the top of the list. Even if they "need" help.
For example if the characters are Cryptoid Bounty Hunters, the last thing they want to do is call the cops/FBI/whatever and have them take the bounty.
This is also true of a basic revenge plot. If the character wants to kill the werewolf that killed his wife, he sure does not want to get that werewolf arrested.
In a general sense, if the world has any Men in Black or Supernatural Hunters or other such secret group....they likely monitor things like phone calls for when people say things like "I saw an Alien at Crystal Lake".
From the meta game side, calling for help also ends the game. Like some creature is in the woods. So a character calls the cops and like 100 cops show up...zzzzzz. Ok, game over, well who wants to play some UNO?
Of course, also the typical "local cop help" can't always help all that much. When a Terminator T-Z28 blows up your house...you call 911 sure. And when they show up the Terminator can kill them too.....

Information does not really end a game or a plot. It is normal for it to be the first step to a climax.
Some sort of 'ghost wolf' attacks your home. You have no idea what it is. But then in Act 2, you run in to the Local Oracle....er...I mean Old Man Farmer McGee, who just happens to know everything about the Gholf...... But, ok, in 2025 you just read it on the internet and don't have to "somehow bump into an oracle".
Also the "good stuff" is often not on-line.
And worse...are the anti-experts. The characters type in 'ghost wolf' in a search and find the United Society of Ghost Wolf Boys. Wow, they have pages of information........................................that is all made up. They just write random articles to get clicks and try to ride on the local legend.
Information can be quite dangerous.....worse as the average player thinks "whatever random information my character hears is 100% true". But that is just silly.......
