To allow pop-ups on an iPhone, the steps depend on the browser you are using—Safari or Chrome.

For Safari (the default iPhone browser)

1. Open the Settings app on your iPhone.
2. Scroll down and tap Safari.
3. Under the General section, find Block Pop-ups and toggle it off (the switch should turn gray).
4. Close Settings and open Safari to browse sites that use pop-ups. You may need to refresh the webpage for pop-ups to appear

For Google Chrome on iPhone

1. Open the Chrome app.
2. Tap the three dots menu icon in the bottom-right corner.
3. Select Settings.
4. Scroll down and tap Content Settings or Site Settings.
5. Find Pop-ups and toggle Block Pop-ups off (the switch should turn gray).
6. Exit settings and continue browsing to allow pop-ups on sites that use them

Disabling pop-up blocking allows legitimate pop-ups like login windows or customer service chats to function properly, but remember to re-enable the blocker if you want to prevent unwanted pop-ups later

. This process applies to recent iOS versions including iOS 17 and iPhone models such as iPhone 11 through iPhone 15
