ELI5: What is being changed when phones are made 5G-compatible?
gpt
Phones are small computers that have a chip and antenna in them that can connect to cell towers via very specific radio signals.

5G signals are different than 4G ones, so phones that support 5G have a different chip and antenna that also speak the 5G language.
