Isekai : Cheat Internet connection

As a smartphone lover, Rei Kuraki comes across a suspicious application when he is looking for a new application, as usual, one day. It seems interesting at once, so when I try DL and play, I suddenly get thrown into another world! Wait a minute, here! Moreover, all data on my smartphone has been lost!!!! That's a lie, my invoice data is left out!!! But this smartphone is awesome!!!! But there are too many billing factors!!!! There are too many tsukkomi! My adventure starts with this. No, I'm not traveling because I just played with my smartphone at the inn. Am I strong in a different world? No, I can't swing the sword properly because I have the same physical strength. Super rich in the Industrial Revolution? No, I ran out of money right away due to too many billing factors for my smartphone. My great thing is I only have a great smartphone ... that? Isn't that worthy of me?
