There are several proven methods for disabling the cellular module, each with its own nuances and suited to different situations. You can choose complete isolation from cell towers or more flexible settings that allow you to receive important calls. The main thing is to understand the difference between airplane mode and manual network management to avoid being left without communication at a critical moment.
In this article, we'll cover all available methods, from a simple switch in the Control Center to deep menu settings. We'll also discuss what owners of models with eSIM and physical cards to ensure your budget stays on track. Follow the instructions carefully, and your trip will be stress-free and financially secure.
Basic Settings: Airplane Mode and Network Management
The fastest and most radical way to communicate with cell towers is to turn on airplane mode. When you activate this feature on your iPhone All wireless interfaces, including Bluetooth and GPS (in some software versions), are completely disabled. This ensures that not a single byte of data is transmitted through the operator's network, eliminating any roaming charges.
However, by including airplane mode, you lose the ability to receive regular voice calls and SMS, which can be critical for receiving confirmation codes from the bank. Fortunately, the system allows for flexible configuration of this mode. After enabling the "airplane," you can manually activate only the module. Wi-Fi, leaving the cellular connection blocked.
To do this, swipe down from the top right corner of the screen (or up from the bottom on models with a Home button) to open Control Center. Tap the airplane icon until it turns orange, and then tap Wi-Fi, so it turns blue again. An airplane icon and a Wi-Fi icon will appear in the status bar, indicating that you're fully connected without the risk of paying for data.
⚠️ Attention: On some iPhone models, Bluetooth is also automatically disabled when Airplane Mode is enabled. If you use wireless headphones or a fitness tracker, be sure to enable Bluetooth separately after activating Airplane Mode, otherwise the devices will not connect.
Fine-tuning: Disabling data and roaming
If you need to stay in range to receive incoming calls or text messages, but want to avoid the risk of paying for data, you should use more sophisticated settings. In this case, we don't disable the communication module itself, but rather prevent the phone from transmitting data through it. This is especially important for those expecting important calls from family or work contacts.
Go to the menu Settings and select a section Cellular communications (or Mobile data). Here you need to find the switch Cellular data and set it to inactive. This will prevent any app from using mobile data, even if you're within your home network or roaming coverage.
Next, you need to make sure that the option is disabled. data roamingWhile in the cellular menu, tap on Data parameters and make sure the switch data roaming Turn it off. This will create a double barrier: even if you accidentally turn on data, your phone won't use foreign networks for internet.
Dual SIM support: Physical and eSIM
Owners of modern models iPhone, starting with the XS and XR, it is common to use two SIM cards: one physical and one virtual (eSIM). Abroad, this configuration requires special attention, as the settings can be applied either to all lines at once or selectively. Incorrect configuration can result in your internet using an expensive SIM card while you think you're using a cheap one.
On the menu Settings → Cellular communications You'll see a list of your lines. By clicking on a specific number, you can manage its settings individually. Make sure the switch for the primary (expensive) SIM card is on. Use this number as default for data is disabled if you plan to use a local card for the Internet.
| Parameter | Primary SIM (Home) | Second SIM (Local/eSIM) | Recommendation |
|---|---|---|---|
| Voice calls | Included | Off | Receive calls to your home number |
| Cellular data | Off | Included | Internet only via local card |
| data roaming | Off | Enabled (if needed) | Protection against write-offs from the main account |
| LTE/5G mode | Off | Included | Saving battery on the main |
It is also worth paying attention to the settings Switching cellular dataThis feature allows the phone to automatically switch to another SIM card if the primary one loses network coverage. This can be detrimental when roaming, so it's best to disable this option to maintain control over your data usage.
What is Dual SIM Dual Standby?
This technology allows two SIM cards to be active and receive calls simultaneously. However, only one SIM card can transmit data at a time. The phone will use the one selected as the "Primary" SIM card for data for internet access, unless configured otherwise.
Configuring application access to the network
Even with data traffic disabled, some system services may attempt to update as soon as a Wi-Fi signal appears, unless restrictions are configured. To ensure nothing unnecessary is happening in the background, it's worth checking your update settings. This is especially important if you're connecting to public Wi-Fi at an airport or hotel.
Go to Settings and find the section Main, then select Software update. Make sure the function Auto-update Disabled or configured to only occur at night and only when connected to a charger. This will prevent heavy iOS update packages from downloading in the background.
In addition, many applications such as WhatsApp, Telegram Apps like Google Play or email clients may have their own data usage settings. In some cases, they may cache media files as soon as a connection is established. It's recommended to disable automatic photo and video downloads in groups in the app settings (Data and Storage section) to avoid wasting data.
⚠️ Attention: The settings interface may vary slightly depending on your iOS version. If you can't find this option, search for "data" or "roaming" in the settings search bar (the magnifying glass icon at the top of the settings list).
☑️ Pre-flight checklist
Use Wi-Fi Calling to Save Money
One of the most useful features for travelers is Wi-Fi Calling (Wi-Fi Calling). This technology allows you to make and receive regular voice calls over the internet using your home network's number. To the subscriber, it appears like a regular call, but it may be charged as a call within your home network, even if you're abroad.
To activate this feature, go to Settings → Telephone → Wi-Fi calling and turn on the switch. It's important to understand that support for this service depends on your carrier. Some carriers allow incoming calls for free and charge outgoing calls at your home network rate, while others may charge per minute, even over Wi-Fi.
When using this feature, "Wi-Fi" may appear in the status bar next to the carrier name. This indicates that the call will be made over the internet. However, if the Wi-Fi signal is lost during a call, the phone may attempt to switch to the cellular network, which will incur high roaming charges. Therefore, when using Wi-Fi Calling, it is strongly recommended to enable airplane mode with Wi-Fi enabled to eliminate any risk of switching to the cellular network.
Alternative solutions: Messengers and virtual numbers
If your primary goal is to stay connected to home, rather than receive calls on your SIM card, you might want to consider messaging apps. Apps like Viber, WhatsApp, FaceTime And Telegram Allows you to make voice and video calls entirely over the internet, completely eliminating the need for a cellular network or roaming charges.
For those who critically need a local number for booking hotels or taxis, there are virtual number services. You can install a softphone app, register a number for your destination country, and top up your balance. This is often cheaper than roaming and allows you to keep your physical SIM card in your phone.
⚠️ Attention: Operator rates and service terms are subject to change. Before traveling, be sure to log into your operator's account or contact technical support to confirm current roaming terms and availability of "Safe Roaming" options or similar packages.
