Here's the note from the seller:
Dear Customer
As described in our item specific, our Note 5 is USA model+Software unlocked.
We would like to inform you that an android phone divided into 2 kinds, i.e. factory unlocked and software unlocked. Factory unlocked means manufacturer allow you to use the phone in Worldwide, so you don't need to unlock the phone & can use it Worldwide, so we called this phone FACTORY unlocked. The other one is SOFTWARE unlocked, for example, a manufacturer set a region lock for a phone for USA region only. If you want to use this phone in UK but originally manufacturer set a region lock for USA region only, so we need to SOFTWARE unlocked this phone & made it can be used Worldwide. USA Samsung offer their phones at the cheapest price in USA, so many dealers purchased phones from USA & sell them to other countries. However, Samsung USA set a region lock for the phones sold in USA at cheaper prices, so the dealers need to SOFTWARE unlocked those USA phones and make them can be used Worldwide. SOFTWARE UNLOCKED also called ROOTED the phone. Please note that if you find a seller declared the phone is software unlocked, then the phone must be rooted. ebay only offer 2 options for us to describe the phone status, software unlocked or factory unlocked, so we can only described our phone is a software unlocked phone(Rooted is a short form of software unlocked).
*IMEI will change after software unlocked,as described in our item description too.
By the way, experienced user loved USA model software unlocked phones because their prices are lower but the phones have same hardware as same as factory unlocked phones. A rooted phone also allowed user to download many Apps for free, too.
Dear customer, we afraid that you're not familiar with how an USA Samsung phone works & not sure about what is software unlocked phone, so lead to the confused.If you need return for full refund, please feel free to let us know & our company responsible for all return postage cost.
Regards
