No; as others have said, radio systems in the 80s were analog, including the first generation mobile phones.
Only analog (now known as "1G", first generation) cellular phones were in use in 1989.
The GSM / "2G" system was just starting to be built in 1991.
Satellites were in use.
The very first was "Sputnik 1", in 1957. It had a radio beacon but no communications relay capability, it was launched for scientific purposes rather than commercial use.
The first communications satellite was launched in 1960. It was a passive reflector, just allowing radio signals to be "bounced" over the horizon.
The first active communications satellite, that received and re-transmitted information, was launched in 1962 - Telstar.
It was used for such as transatlantic telephone and television links
There were plenty of others by the 1980s!
