If you get the phone through AT&T (or locked to AT&T) you get the version with the Intel modem, which cannot be used in certain countries (and, if you wanted to switch to Verizon, you cannot take your phone, even if unlocked). As far as I know, the unlocked phones are the Qualcomm versions, which can be used on all networks worldwide.I am with ATT and will be for as long as possible because I have the grandfathered in unlimited data. Would there be any reason I would want to get a SIM free phone? I do travel a lot internationally.

But if you travel to a CDMA country, 100% if carriers use CDMA.The att iPhone can be used on all gsm carriers once unlocked.
It just won't work on cdma carriers like Verizon and sprint. 99% of international carriers use gsm.
But if you travel to a CDMA country, 100% if carriers use CDMA.
Never Land?What country has 100% only cdma carriers available?
What country has 100% only cdma carriers available?
And none of those 20-25 countries are cdma only.
GSM is available everywhere.
Definitely not, but there are a number of countries (primarily Asia) where the most major carriers still operate CDMA on their 3G networks. So if you aren't in a city that has LTE coverage everywhere, you need that CDMA radio to stay connected. I've needed this a few times this year and thank goodness I had it because I needed maps access.
You can choose a carriers sim network that uses gsm 3G instead of cdma.
Cdma is dead technology and some of the few locations that still have it available you wouldn't want to visit
Well, the traveling a lot internationally part might play a role in that if you potentially might using different providers where you travel.
You mean, such as Korea? We are not talking visiting Kim Jong-Un.You can choose a carriers sim network that uses gsm 3G instead of cdma.

That's not how it works. On legacy GSM networks, if no LTE service is available, it defaults to 3G HSPA. On legacy CDMA networks, if no LTE service is available, it defaults back to 3G EVDO. So say you're on Setar in Aruba, and in an area not covered by LTE, you're going to need a CDMA-compatible radio, or you're not getting data service.
Now, I agree, CDMA is dying and will be completely dead soon. In most places you can find a carrier that doesn't rely on it. But if you're a frequent international traveler that goes outside of major cities (this is me), it is still valuable to be able to connect to old legacy networks.
Disagree. But I like to travel.
Yes, perhaps. But, again, T-mobile states that the their iPhone 7 cannot be used in Korea.LOL, hopefully if you visit Korea you'll stay south of the 38th parallel, otherwise you won't need your phone anyway.
And by the way, there are LTE networks available in S. Korea along with GSM in addition to CDMA2000.
The phone doesn't come with a SIM and you just put one in from whatever provider you want to use.so how does the sim free work? In many Asian countries the GSM networks of each company give their own SIM card when they open an account. So how do they provide you service without their SIM card? Many of these countries may not be set up that way. Now if one is roaming that is different. But I generally carry a second phone and buy a local SIM at the airport for the duration of my overseas stay in that country.
