I sometimes use Bluetooth to send images, but mostly now I use the wifi to transmit images using my social media app.
I am not a pro photographer, and to be honest, my new phone has a much better twin lens (regular and macro) camera than my travel camera. As such I can use the file share facility on my social media app to send photos to myself over wifi, or using mobile data When I get home I just open my social media app on the PC and my photos are there, as well as on the phone app, and in the phone's picture folder. This is also more secure when travalling as I cannot lose pictures if my phone is lost or stolen.
There are several apps now that are free to use, free to send data, and I have yet to find the limit for files sizes. A few months ago I could share 9 images, recently it changed to 99 images (possibly due to 5G), which is a huge amount of data, with no data fee.
I can still use a physical connection, but rarely use it these days.
Like I say, I am not a pro-photographer, or a hobby photographer that plays with pro-editing tools. 20mp images are more than enough for my needs.
