Starlink[0] is made for you. It's a constellation in low-earth orbit, so latency is far lower than 650ms (current users are getting around of 30-60ms.) The current iteration must stay within the "cell" it's assigned to, which is only a few miles wide. But in the future, there will be a version available that'll work almost anywhere in the world.
