Near the end of the movie, we see the letter from Lagos. However it seems to be encoded. What does it mean?
According to this post on MyAnimeList forums, this is the message:

This E-mail is an appeal to all recipients.
We are alive We were spared the effects of the anti-gravity experiment.
We have yet to fully grasp the extent of the destruction But we are absolutely certain that one particular undamaged area remains; namely, the area on the exact opposite side of the Earth's mantle. This is the reverse side of the Earth's axis.
After settling that area, we pushed forward with research into the repair of gravity inversion. Now it seems a successful breakthough may by just out of reach. We have placed our hopes in the networks still online in each area, and are transmitting this E-mail all over the Earth.
To all recipients: please print as many copies of this E-mail as possible. Then please distribute those copies to as many people, as you can, so that they may know the truth.
We are resolved to wait in here, for generations if necessary.
Latitude 33.3526' N, Longitude 130.2401' E
Please convey this to all peopple on Earth. We are alive.
