How to Request Desktop Versions of Mobile Websites in Safari on iPhone for iOS 13, iOS 12, iOS 11
Generally speaking, using a websites intended mobile version is recommended when the site is accessed from an iPhone or iPod touch, since mobile websites tend to be optimized for smaller screens. Nonetheless, sometimes a user visiting a mobile site may wish to access a desktop version of the same website from their iPhone, iPod touch, or iPad, without having to use Handoff to pass the page off to a Mac.
You can request the desktop version of a webpage easily in Safari with new versions of iOS, though if you’re familiar with the older approach then you’ll notice the feature is accessed differently than prior versions of Safari on iPhone and iPad.
