How can you download iSim and install it on your iPhone?
Hi how can i find free isim to download for my iphone thanks dear ?
Well, to install iTunes on your computer you don't have to use your iPhone. You just go to the Apple website, and search iTunes, and then you can just download it from there. If you want to sync your iPhone with iTunes to back up your content, you just sign in with your Apple ID (if you have an iPhone you should already have one), then plug in your iPhone and press sync.
