Travel leaves settings behind. The three that most often survive the flight home are a manual network selection made abroad, a travel eSIM still holding the data role, and Data Roaming left switched off after you turned it off to avoid charges. The manual network selection is the nastiest of the three, because it makes the iPhone keep hunting for a foreign network that no longer exists here. Apple's own guidance points the other way for outbound travel — that Data Roaming needs turning on — and the same switch left in the wrong state on the way back causes the mirror-image problem. A travel eSIM adds a second failure mode: it is still installed, still selected for data, and now has no valid plan, so data fails while calls on your home line work normally. **Important:** Reset Network Settings erases every saved Wi-Fi password and VPN configuration. Make sure you can rejoin your home Wi-Fi before using it. ## What should I try, in order? - Open Settings, Cellular, Network Selection and turn Automatic back on. A manual choice made abroad will not register here. - Check Settings, Cellular, Cellular Data Options and turn Data Roaming back on if you switched it off. Some US plans need it on for partner coverage. - If you used a travel eSIM, open Settings, Cellular and make sure your home line is selected under Cellular Data and Default Voice Line. Turn the travel line off. - Toggle Airplane Mode for 15 seconds, then restart the iPhone. - Check Settings, General, About for a carrier settings update. Foreign carrier settings can persist and need replacing. - If data still fails, Reset Network Settings — this clears every leftover foreign APN and preferred-network entry in one go. ## Which carriers does this apply to? | Published for | any iPhone, Verizon, AT&T, T-Mobile and UScellular | | Type | iOS setting | | Good to know | Applies to any iPhone returning from abroad. If you used a travel eSIM, its plan may still be active and consuming the data role. | _Screenshot: The Secret Codes detail screen shows the steps, the carriers and an Open in Phone button._ ## Related fix iphone phone problems - [Your 911 Address Is Rejected](/blog/your-911-address-is-rejected-iphone/) - [Unexpected Roaming Charges](/blog/unexpected-roaming-charges-iphone/) - [Wi-Fi Calling Will Not Turn On](/blog/wi-fi-calling-will-not-turn-on-iphone/) - [Wrong Name Shown To People You Call](/blog/wrong-name-shown-to-people-you-call-iphone/) - [Calls Going Out On The Wrong Line](/blog/calls-going-out-on-the-wrong-line-iphone/) - [Your Number Is Flagged As Spam](/blog/your-number-is-flagged-as-spam-iphone/) See all [fix iphone phone problems](/blog/iphone-codes/fix-iphone-problems/) or [every category of iPhone codes](/blog/iphone-codes/). ## How Secret Codes helps Secret Codes keeps this and every other entry a search away.
