Seller that its fully unlocked for any network in GSM / CDMA in US and can be used for any sim in US but it also works internationally but depends on carrier. Below is the exact same reply from seller. Thats why confused me, but since its 100% unlocked ( i have also checked putting any US sim card and it works and also checked with IMEI number online and its showing as UNLOCKED )
"while the phone is 100% unlocked some carriers in different countries around the world might not be able to provide you service with this specific phone model. While these phones work internationally, it really depends if the carrier in your country support the USA model phones and their bands.
Unfortunately, we cannot guarantee that the phone will work in different locations around the world as it depends on the local carrier and not the phone.
The device will work with any GSM or CDMA networks in the US
"
Secondly, i see few of the carrie's band of India and it matches with above.
Please guide to clear my confusion. Please it would be great help.
