You won't have LTE. I'd just go get an AT&T iPhone.
DUH! Of course, lol.
Am rich, lol. If I want an LTE, I'll pit my Verizon nano sim card - if there's no LTE, and I want voice & data on fast faux 4G, AT&T nano is going in.
Yeah, I noticed this, too. It's pretty cool, been using my Verizon phone on AT&T for a few days now.
Only problem I've found so far is that my family gets a busy signal when trying to call my AT&T number from their Verizon phones, even while I'm not on a call or phone is on sleep. Can't figure it out
If you're that "rich" then why not just have both models if you need both carriers. No SIM swapping then....
