Can I use JIO 4G sim in my Samsung Note 2? Note 2 supports 3g AND 2g. There is no 4G in the phone. If not, is there anyway I can use 4G with this phone or any other cheaper option?
I am afraid you can’t use Jio with your phone. There are several hacks available online that claims to make the sim work on 3G phones. I haven’t tried them but comments to such articles suggest they are mixed bag. Go for new phone.
