There are some ham radio call phones that can transmit. They're pretty specialized and not cheap, but they exist… around $1200 for what is essentially 3+ year old phone hardware (with software to match … Android 9-ish) with a built in transceiver… I like the idea, but I'm not paying that much for a very old phone because it happens to have a ham radio built in.
The current ideas with adding radios to phones is almost entirely to pick up broadcast radio, like am/FM. Nothing fancy.
I'd imagine no phone would have transmission ability, or at most transmit like a Walkie talkie
