I wants to check new model in iphone
You can get an iPhone XR or an iPhone XS. Those are the newest models.
But I don't know how much will they cost
The iPhone XR starts at $449 and the Xs starts at $700 if you trade in a previous iPhone.
Can we have trial sessions to see their fast working
They are fast working but they are slower than other smartphones on the market.
So shall we see any other smartphone models
Samsung makes a Galaxy Note 9 and a Galaxy A6
But will they work as iphone?
They will not. They are Samsung phones.
But I prefer iphone. Don't you?
