I would use wifi, but the places that I go to usually have them locked. I have a AT&T line as well, so that helps. I may decide to cancel my T-Mobile account.

You know T-Mobile gives free nationwide roaming. My roaming setting is always checked and our note 3 supports Att signal. It will always search for T-Mobile first but you can always switch it manually.
If I'm not mistaking it's free voice and text and 500 mbs of data a month nationwide roaming.
