As a first step, work on weaning yourself off of synchronous communication wherever possible. Limit your synchronous communication to only the minimum necessary to operate efficiently.
Create a routine of sending of ultra-concise weekly updates to the team. Your goal should be to produce reports that the teams actually enjoy reading. People should walk away from the reports feeling like they know what they need to know, what's expected of them for the week, when it's expected, and who to contact if any exceptions come up. The goal is no surprises, no hidden expectations, and visibility into the team goals. If people have to synchronously talk to you or wait for a specific meeting, work on improving the weekly update.
Fill in the gaps with daily updates for any relevant changes. Work on collecting updates, summarizing, and sharing them at the same time every day for predictability. Don't get in the habit of pinging everyone every time you have a question. People will hate the constant distractions.
Finally, carve out time for predictable, synchronous weekly meetings. Make it predictable, at the same time every week. Resist the urge to schedule spontaneous phone calls every time something comes up. Practice excellent meeting discipline, with an agenda shared ahead of time, careful attention on managing off-topic discussions, and so on.
On the other hand, if your organization is not remote to begin with, and most of the staff is in an office, a remote PM most likely would not be able to work out in such an org.
The other 10% of those could simply be phone calls or screen shares.
Writing things down and having documented (and followed) processes is good! And helps with onboarding as your knowledge-base grows, and (in my experience) costs a lot less that not everybody being around the watercooler when "that" conversation happened.
I function a bit more as a communication hub than I used to in previous non-remote roles, and I put much more stuff in writing than I used to.
Remote work forces you to be way better with knowledge management, but honestly it clearly is just a best practice for any time that's big or about to grow.
