[Q] Google Voice and T-Mobile Prepaid topic

I apologize if this question has been answered before, but all of the information I've found regarding this is outdated (threads are all from before the Hangouts Dialer was released).

I'm on the T-Mobile prepaid plan (100 minutes, unlimited text/data). I've always used Google Voice for voicemail and I would prefer to keep doing so. I do have a GV number separate from my T-Mobile number. I always give out the GV number as my main cell phone number now that MMS and pretty much everything else is supported on GV. Some people still call my T-Mobile number instead of my GV number, however.

Now that the Hangouts Dialer is out, I can use that to place outgoing calls from my GV number using data and not my minutes which will be good for saving those minutes. My main questions are the following:

• Do I need to select the option to receive incoming GV calls in the Hangouts app to use data for those calls (or to even get them to my phone at all, since T-Mobile prepaid doesn't support call forwarding)?


• Is there a way to use GV's voicemail for incoming T-Mobile calls or do those have to function normally (using my normal phone dialer and the normal phone/T-Mobile voicemail)?


• Are there any other considerations I'm missing that I should be aware of? Any additional advice would be greatly appreciated.

I used to use T-Mobile's prepaid plan but am now switching back after two years of Straight Talk, so I've forgotten most of the T-Mobile prepaid considerations and I don't know how things have changed, especially with the release of the Hangouts Dialer. Any advice at all would be very much appreciated. Thank you!
