How to disable roaming on your phone in a few steps
To disable roaming, go to your phone settings, look for the mobile networks or mobile data section, and turn off the "data roaming" (or "data itinerancy") option. On Android, it's usually under Connections or Mobile networks; on iPhone, under Settings > Mobile Data. The change applies immediately, without restarting the device.
The exact name of the option changes slightly depending on the phone brand (Samsung, Motorola, Xiaomi, Google Pixel) and the operating system version, but its location is always the same: the connections or networks menu, not the applications or battery menu. If you're in a hurry, the next two sections provide the exact steps for Android and iPhone, with screenshots of where to tap in each.
A clarification before we continue: roaming is a service activated by your operator so that your line works outside your usual coverage area, usually with an extra cost per minute, message, or megabyte. Disabling it does not cancel your plan or your line: it only tells your phone not to connect to other operators' networks when yours is unavailable.
Disable roaming on Android step by step
Although each manufacturer organizes its menus slightly differently, the general path on Android is as follows:
- Open Settings (the gear icon).
- Go to Connections or Network & Internet, depending on your model.
- Tap Mobile networks (sometimes appears directly as "Mobile data").
- Look for Data roaming or Data itinerancy and turn off the switch.
If your phone has two SIMs (one physical and one eSIM, or two physical), this setting usually appears separately for each line. That is, turning off roaming for line 1 does not turn it off for line 2: you have to go into each card and check its own switch. This is one of the most common reasons why someone swears "I already turned it off" and still sees charges: they turned off one line, but the one connected at the time was the other.
Some models add a pop-up warning the first time you try to turn off roaming, asking if you are sure because you might lose mobile data outside your area. This is a normal confirmation message, not an error: tap accept or "disable" to continue.
Disable roaming on iPhone step by step
On iPhone, the process is shorter because Apple centralizes everything in one menu:
- Open Settings.
- Tap Mobile Data (or "Cellular," depending on the iOS version).
- Scroll down to Mobile Data Options.
- Turn off the Data Roaming switch.
If your iPhone has two active lines (one physical and one eSIM, common in recent models), the "Mobile Data" menu will show both separately, and each has its own roaming switch. Just like on Android: check both if you're not sure which one is in use.
A detail specific to iPhone: if you have "Automatic Mobile Data" activated so that the device switches lines automatically based on coverage, that automatic switch can reactivate roaming on a line without you noticing. If you plan to keep roaming off permanently, it's advisable to also disable that automatic switching option.
What happens if you disable roaming
Disabling roaming cuts off your mobile data connection (and, in some cases, calls and SMS) when you are outside your own operator's coverage area. What always continues to work, with or without roaming, is any WiFi connection: WhatsApp, email, social networks, and internet calls continue to function if you have a WiFi network available.
| Function | Roaming activated (outside your area) | Roaming disabled (outside your area) |
|---|---|---|
| Mobile data (4G/5G) | Works, with possible extra cost | Does not work |
| Incoming/outgoing calls via mobile network | Works, with possible extra cost | Depends on the operator: some also cut them off |
| SMS | Works, with possible extra cost | Depends on the operator |
| WhatsApp, email, and apps via WiFi | Works the same | Works the same |
| Emergency numbers | Works | Usually continues to work (varies by country and operator) |
The emergency and calls/SMS rows depend on each operator and country, so they are not a universal rule: if you are going to rely on them, confirm with your operator before traveling.
If your phone shows "No service" right after disabling roaming, it's not a fault: it's exactly what's supposed to happen. The device stopped looking for other operators' networks because you asked it to.
"Roaming" still appears after disabling it: why this happens
This is one of the most frequent complaints: the person swears they turned off roaming and the icon is still there, or they keep getting the "you are roaming" notification. This is almost always due to one of these four causes, ordered from most common to least common:
- You disabled the wrong line. On a dual SIM phone, each line has its own switch, as explained above.
- You confused "data roaming" with "airplane mode." Airplane mode cuts absolutely everything (calls, SMS, data, and WiFi), not just roaming, and it's not the same.
- The icon is informative, not an error. Many phones show the "R" or "roaming" symbol simply to indicate that you are outside your usual coverage area, even if data is already off. This is normal and does not mean you are being charged anything.
- The change was not applied because the phone had no signal at that moment. On devices with poor signal, the switch sometimes takes a few seconds to confirm. Exit and re-enter the menu to verify that it is off.
If, after checking these four points, the problem persists, it is probably not a phone issue but a network configuration issue with your operator (for example, a plan that forces roaming in certain border areas). In that case, the correct approach is to report it directly to your operator.
Data, voice, and SMS roaming: they are not the same
The most frequent mistake when trying to "disable roaming" is assuming there is a single switch that turns off everything. In reality, an operator can bill data, call, and message roaming separately, and the setting you see on your phone almost always controls only data.
| Type of roaming | What it covers | Where it's controlled |
|---|---|---|
| Data roaming | Mobile internet (browsing, apps, streaming) | Switch in phone Settings |
| Voice roaming | Incoming and outgoing calls | Generally managed with the operator, not from the phone |
| SMS roaming | Text messages | Generally managed with the operator, not from the phone |
This is why it can happen that someone disables data roaming from their phone and still receives a call or SMS with a roaming charge: the phone's switch does not affect these two layers. If you want to completely protect yourself, the only sure way is to ask your operator to block voice and SMS roaming from their system, in addition to turning off data roaming from your phone.
How to confirm that roaming is actually off
After toggling the switch, it's advisable to verify it with a simple test instead of relying only on the menu view:
- Go back to the same menu (Data Roaming / Data Itinerancy) and confirm that the switch is still off.
- Turn off WiFi for a moment and try to open any page or app that needs internet. If nothing loads, roaming is indeed blocked.
- Check the top bar icon: if an "R" or "roaming" text appears but you have no data connection, it's just the informative notice mentioned earlier, not a fault.
This test is especially useful just before crossing a border or getting on a flight: you confirm it's off while you still have WiFi to sort out any settings, instead of discovering it in another country with no way to fix it.
When to leave roaming activated
Turning off roaming is not always the best decision. It makes sense to leave it activated in a handful of specific situations:
- Very short trips (one or two days) where the operator offers a roaming package with a fixed and known cost in advance.
- Work or errands that depend on receiving calls to your usual number, and you have no way to forward them to another medium.
- Areas without reliable WiFi where you need emergency data for a short time and have already validated the cost with your operator.
Outside these specific cases, for trips of several days, the calculation usually changes: your home operator's roaming tends to be the least predictable option in terms of cost, precisely because it is billed per consumption and per country, and that rate depends on the operator and is not set by PuraSIM or any other third party. The most common alternative to control spending before traveling is to contract local or international data separately, leaving your home operator's roaming turned off as a backup.
If you need data while traveling without relying on roaming
If you disabled roaming because the real problem was the cost or the unpredictability of the charges (not a phone error), the next logical step is to solve your travel data needs through another channel, without turning that switch back on. This is where a data eSIM comes in: you install it before leaving home, activate it when you land, and it works in parallel with your usual line, which you can leave in calls and SMS only mode via WiFi.
PuraSIM offers data eSIMs for over 200 destinations, with activation in approximately 1 minute after purchase, and a 180-day period to activate it from the moment of purchase (no need to use it immediately). If anything is unclear during installation or activation, support is available 24/7 in all languages via email and WhatsApp, without the need for a phone call.
You can check the available plans by destination in the international eSIM collection, and if you have never used an eSIM, it is advisable to first understand what an eSIM is and confirm that your phone is compatible before buying.
Frequently asked questions
How do I disable roaming for personal use on my phone?
The setting is on the phone, not in the operator's app: on Android, it's under Settings > Connections (or Network & Internet) > Mobile networks > Data roaming; on iPhone, in Settings > Mobile Data > Mobile Data Options > Data Roaming. Turn off the switch, and the change applies immediately.
How to disable roaming service?
It is disabled from the phone itself, by looking for the "data roaming" or "data itinerancy" option in the mobile networks menu. It is not necessary to call the operator or cancel any plan; the phone's switch is sufficient to cut off data roaming.
What happens if I disable roaming on my phone?
You will no longer have mobile data (internet) when you are outside your operator's usual coverage area. Apps that depend on WiFi, such as WhatsApp or email, will continue to work normally if you have a WiFi network available. Calls and SMS depend on the operator: in some cases, they are also cut off, in others not.
Where is roaming activated and deactivated?
Always within the phone's own settings, in the connections or mobile networks section (never in the applications menu or the battery menu). The exact name varies by phone brand, but the general location is the same on Android and iPhone.
Does disabling roaming also block calls and SMS?
Not necessarily. The phone's switch primarily controls data roaming. Voice roaming (calls) and SMS are usually managed separately, at the operator level, so you may still receive calls or messages with roaming charges even if you have turned off data.
Why does my phone still show "roaming" after I've disabled it?
The most common causes are: you turned off roaming for the wrong line on a dual SIM phone, you confused roaming with airplane mode, or the icon is merely informative (it indicates you are outside your coverage area even if data is already off). Check each line separately and confirm with the test of disabling WiFi to see if there is actually a data connection.
Do I need to disable roaming before traveling if I'm going to use an eSIM?
It's advisable to disable data roaming for your usual line so that the phone doesn't try to use that network and accidentally incur charges, and keep mobile data active only on the eSIM line you installed for the trip. Calls and SMS via WiFi (WhatsApp, for example) do not depend on either.
Does disabling roaming affect WiFi?
No. Roaming is a setting exclusive to the mobile network (data, calls, and SMS from your operator). WiFi is a completely separate connection: it works the same whether roaming is activated or deactivated.
In summary
Disabling roaming is quick and done from the phone itself: on Android under Connections > Mobile networks > Data roaming, and on iPhone under Mobile Data > Mobile Data Options > Data Roaming. If you have two lines, check each one separately, and remember that this switch almost always covers only data, not calls or SMS.
If what you were trying to achieve by disabling roaming was to avoid unpredictable charges from your operator, the natural next step is to sort out your travel data with something whose cost you know in advance. That's where PuraSIM's international data eSIMs come in: they activate in approximately 1 minute, cover over 200 destinations, and if anything goes wrong with the installation, 24/7 support is available via email and WhatsApp in all languages, without needing a phone call to the operator. You can first review how to install an eSIM or directly compare eSIM vs. roaming to decide with clear figures which is best for your next trip.
