Even the PT shows this. Queen Amidala has to physically fly to the capital to explain what's going on. They don't just flick to the GoogleNaboo app. The Trade Federation denies it.

All this strongly implies that mass communication in the SW universe is difficult, inconvienient, and not generally a priority.

Amidala had to flee Naboo in order to avoid capture.

Why doesn't she message Coruscant once they've landed on Tatooine? Remember, she receives a message from Governor Bibble urging her to contact him. Qui-Gon tells her to send no reply. Why? Because her reply could be traced back to its point of origin. Same for if she sent a message to Coruscant. So the only safe thing to do was maintain radio silence until they safely made it to their final destination.

You also forget the intergalactic message between Obi-Wan on Kamino and the Jedi Temple in AOTC.

What doesn't make sense is why Obi-Wan can have a live conversation between Coruscant and Kamino which is described as being "beyond the Outer Rim." But then later has to relay a recorded message from Geonosis to Tatooine before it can reach Coruscant.
