iPhone 6(S)/Plus Do iPhone 6s Plus dual sim adapters work ?

Or is it better to just get the one of the latest iPhones for dual sim ?

These products look very limited and can only allow you to call, text but not data. I think feature set depends on manufactures. I Don’t even know this thing exist until today to be honest, so thanks for refreshing me.

As for the practicality, I think it is still a bit less convenient than actual dual sim support by iPhone XS Max.
