Cool Unlocked Meaning

Unlocked means that you are not tied to a specific cell phone company and can cancel from 1 company and move it to another. It is more expensive, but some people do not like being stuck with 1 cell provider.

Wow..that was very educational. What a nice response to a question that many have pondered by many but were afraid to ask...

There are/were basically four high frequencies cellphone bands that are used worldwide in different areas of the world. They are 850, 900, 1800 and 1900 or derivatives thereof. Two of these are GSM (with Sim card) and the others are CDMA. Most cellphones use only two bands in a particular country. International phones are able to work on any of the four bands and usually cost more. So you do not have to buy a different phone to use in another country. If you live in the US you could step off a plane with your same phone in Europe and make a call. This is the reason one carrier's issued phone even here in the US may not work with another carrier. As 4G and 5G showed up things are a little more complicated now with smart phones and such; but this is the basic reason for the difference.

I forgot. Unlocked means it will work on other carriers whether in US or other. International means it will work on all four bands. So Unlocked International is the most flexible. Double sim card phones means you can have two completely different phone numbers on one phone that operate independently as if you are holding two phones. You can even put one on hold and answer the other number, different call waiting, etc. Work and personal, etc. You have to pay for two lines from the carrier of course.
