How do I transfer / send a file from my Mac to my cellphone via Bluetooth?

I think different phones have different levels of bluetooth capability.

One of the phones in my household does not "support" bluetooth file transfer, and after pulling out my hair for a while, I gave up and used a MicroSD card to do the transfer. It's a brand new Verizon low-end LG phone, can't remember the model name but bluetooth sees it as VN-250.

Another phone we have is the Verizon G'Zone. This one sends up a warning window on the Mac's screen claiming it can't accept jpg files but the warning can be skipped and then the files transfer just fine. No browsing the phone, though. This is a middle-of-the-line phone from last year.

The LG Voyager (VX 10000) was a high-end fancy phone from Verizon about 4 years ago. This one has great bluetooth support. You can browse its files from the Mac, send and receive, and no dumb error messages.

In conclusion, some phones have very limited bluetooth capabilities. Especially Verizon phones (those feature-disabling rascals).

Dan, you're right on both counts. Bluetooth is a communications protocol and different devices support different capabilities "on top of" bluetooth. You can't browse the iPhone file system via Bluetooth, for example, but there are other BT capabilities it supports. Stupid, really, but that's just my opinion as an end customer.

In terms of Verizon, heck yes. I was shocked a few years ago when I had a Verizon Motorola RAZR then Motorola sent me a stock RAZR with the Motorola operating system on the device. It was totally different, easier to use and supported capabilities like bluetooth file transfer that the Verizon version had removed. Again, as an end consumer it was infuriating, but I think we basically rent access nowadays, even as we think we own the devices.
