Nice phone at a good price. I am using it with Straight Talk. This is a 2016 Galaxy J7. Dual Sim version. It is for distribution in China and has "China Mobile" engraved on the back. The phone language and all packaging is in Chinese. This is not really a problem, just something to be aware of(unless you read Chinese, if you do all is good). To change the language, find the Settings Icon then scroll to the last section under Settings( in green) look for the "A" in the green circle and select this option. The first option under the green "A" will change to the language of your choice. Once you get the phone language changed it is a pretty decent phone. I only gave 4 stars because it seems like the phone reception is not really good and it doesn’t have a very loud ring tone.
