Dick Tracy already had a 2-way wrist radio in 1946. It was inspired by existing technology - e.g. the walkie-talkie.
What I find interesting is where science fiction writers really miss the boat with out-of-date technology.
A great example was the scifi view of computers, they almost all saw them as getting bigger and bigger physically, some even planet sized.
Anyone so limited that they can only spell a word one way is severely handicapped!
