Apple on Friday introduced its new SIM-free iPhone 6s, which offers the largest range of bands for global roaming support. As it turns out, this phone is apparently the same model being sold for AT&T, and Apple recently updated the specs page to reflect that it actually supports CDMA networks, which weren’t previously listed.

9to5Mac noticed some of the changes on Apple’s site, where the new Model A1633, the SIM-free iPhone 6s and the same one sold for AT&T, now lists CDMA EV-DO Rev. A 800, 1700/2100, 1900, 2100MHz networks, which previously were not listed for that phone, and instead for the A1688 and A1687 models. Because this phone also supports LTE Band 30, used by AT&T, it appears this phone is the one you want if you suspect you’ll be moving between carriers (especially over to AT&T) or traveling the globe. 9to5Mac said this also applies to the iPhone 6s Plus model A1634.

Now, the real difference ultimately just comes down to that Band 30 — since CDMA was supported all along, we just didn’t know it — but the changes tell us that the AT&T model is a lot more robust than previously thought, and should actually operate on global and local CDMA networks (Read: Verizon, Sprint) just fine.

Don’t get too excited, however. Nothing changes if you have this phone on AT&T and it’s still carrier locked.
