You turn it on and pick a region under Lock screen and AOD. If you cannot change the city or clock style you expect, the cause is usually a separate control: a World Clock widget with its own location setting, or a dual-clock style that Roaming clock can block. The steps below cover both.
How to turn on Roaming clock
Samsung’s regional support page for Roaming clock, last updated 28 April 2025 and written for the Gulf region, gives this path:

- Open Settings and tap Lock screen and AOD.
- Turn on Roaming clock.
- Tap Region.
- Choose the country and city you want displayed.
Menu labels can differ by model, software version and region, so if the wording on your phone is slightly different, look for the Roaming clock switch inside the lock-screen and AOD settings.
What Roaming clock displays, and where
According to Samsung’s page, the selected city’s time appears on the lock screen. It also appears on the Always On Display when AOD is active. If AOD is off, the feature is only visible on the lock screen. Samsung describes Roaming clock as a travel feature that shows local time; it does not describe it as a setting that changes the phone’s own date or time.

Roaming clock and Android’s time settings are separate controls
Samsung phones run Android, which has its own time controls. Google documents automatic date and time, automatic time zone, and an Automatic home clock option in the Clock app’s settings. Google also states that the device may use location to set its time zone, depending on whether Use location is enabled. Those controls govern the phone’s clock. Roaming clock governs which city is displayed on the lock screen. Keeping them apart explains most of the confusion:
| Control | Where it lives | What it changes | Source |
|---|---|---|---|
| Roaming clock | Settings > Lock screen and AOD | Displays the selected region’s time on the lock screen and, when active, on AOD | Samsung regional support page, updated 28 April 2025 |
| World Clock widget location | Touch and hold the lock screen, then tap the World Clock widget | The city or time zone shown by that widget | Samsung Members support response (model and version not specified) |
| Automatic date, time and time zone | Clock app settings | The phone’s system date, time and time zone, which can follow the network or location | Google Android documentation |
If you want the phone itself to show the local time of a new country, the system time-zone controls are the relevant ones. If you only want a second city on the lock screen, use Roaming clock or the widget.

Roaming clock seems to block a different clock style
In a Samsung Community thread about a Galaxy S24 Ultra, users and a community reply describe turning off Roaming clock before they could select a separate dual-clock style. This is community troubleshooting tied to one model and software version, not an official Samsung instruction. If you need the dual-clock layout, try turning Roaming clock off first, then choose the style you want, and turn Roaming clock back on only if you still need it.

The phone’s time zone is wrong, not the lock-screen city
If the phone’s own time is incorrect, Roaming clock is not the cause. Check the automatic date and time and automatic time zone settings in the Clock app, and confirm whether Use location is on if you rely on location-based time zones. Changing the Roaming clock region will not correct the phone’s system time.

Common questions people phrase this way
People often search for the problem in plain terms, such as “how do I change the time zone for the clock widget on my lock screen” or “how do I add a second time zone to the lock-screen clock.” Which route applies depends on the answer to one question: do you want a travel-oriented local time handled by Roaming clock, or a city you pick yourself on a widget? Start with that choice, then use the matching steps above.
