Welp, that pretty much settles it! So to sum it up:
-If TMob doesn't work, I should get an AT&T sim card, but I have to find out if 4G works on straight talk this way.
-No advantage to straight talk over t mobile except unlimited everything?
-The relay is a good purchase
-I should sell this POS galaxy S4 quickly so I can buy a relay, haha.
Even if a droid 5 comes out...I dunno. I HATE the keyboard of the droid 4. I don't know why the keys have to be right next to each other!
If anyone else has comments, let me know! I live in Central New York and they seem to have coverage.
