How do I enter a URL into a smartphone without performing a search?

Scenario: I talk to someone in person and during the conversation I think of a website whose URL I know from the store, and I want them to put the URL into their smartphone and access the site directly without doing a web search (So As you could do with a traditional computer web browser in the address bar).

To be clear: I do not want to do "search while typing". I do not want to make suggestions based on partial matches, and I do not want it to do any sort of search that returns search results. I do not want the input string to be sent to a search engine to do any processing. I just want to connect to the specified website (ie Direct to DNS lookup, followed by an HTTP or HTTPS connection to the specified URL). In this scenario, I also have no way to generate a QR code for them (I do not have a smartphone and may not carry my computer with me).

Do smartphones have this option (ie a field in which you can enter a URL without passing it to a search engine, just like the old browsers used with the address bar)? If so, how can I instruct the Android user (and / or iOS user) to find the field in which the URL can be entered and not processed by a search engine?
