Pretty much all satellites from before DD are either burned out of orbit, or non-functional. A small number have been launched in the last few years by Siberia, the SAC, and the ANZC, but that's it. Despite being similar construction to pre-DD sats, these ones will probably not last as long due to orbital conditions, too.

Shortwave radio, quite limited. With the Sats down, the hurts their range, as does the lack of repeaters on the ground - the repeaters in place prior to DD are in many ways useless right now, between damage and a lack of maintenance. The repeaters, though are being rebuilt/repaired, and in some areas would be operational for long distances, most notably in the NAU and Siberia. Past that, you'd have higher-range transmitters and receivers in some of the better off areas of the world (i.e. ANZC and SAC, and able to bounce off the atmosphere somewhat) able to be used as well, but not really on a commercial level. There would still be a small amount of atmospheric interference up there with regards to "bouncing" like this, too.

International Air Travel exists, though toned down from otl. Regular flights would exist between the countries that are better off, though the ones doing worse (and the smaller states, overall, too) would not have this.
