Disabling cellular communications on iPhone while saving work Wi-Fi — a problem users face in a variety of situations. Some want to save battery life, others want to avoid roaming charges abroad, and still others simply need internet without making calls. But disabling "Data Transfer" by default Settings → Cellular often leads to unexpected results: both mobile Internet and Wi-Fi disappear, or the device automatically connects to 4G/5G when the router signal is weak.
In this article we will look at 5 proven methods turn off the connection on iPhone (including models with eSIM), while maintaining work Wi-FiWe will pay special attention to the nuances of different versions. iOS (from 15 to 17), Airplane mode, and hidden settings not mentioned in the official guides. You'll also learn why sometimes Wi-Fi turns off by itself after updating the system and how to fix it.
Method 1: Airplane mode with manual Wi-Fi activation
The most obvious, but not always correctly working method is to use the mode On the planeIt disables all wireless modules, including cellular communications, but allows you to manually activate Wi-Fi And Bluetooth.
How to do it:
- 📱 Open Control center (swipe down from the top right corner to iPhone X and newer, from bottom to top on older models).
- 🛫 Click on the icon Airplane Mode** (airplane). Wait 2-3 seconds until the indicator turns orange.
- 📶 Now press and hold the icon «Wi-Fi»** (Antenna signal) - a menu with a switch will appear. Turn it on.
⚠️ Attention: On some firmware (especially iOS 16.4–16.6) after reboot iPhone may automatically turn off Wi-Fi, even if Airplane mode is active. To avoid this, check your settings in Settings → Wi-Fi → Auto-connect to networks and disable the option Automatically join networks.
Method 2: Disabling cellular communications in the settings
If Airplane mode is not suitable, you can turn off the connection directly in the menu Cellular communicationsThis method works on all versions. iOS, but has nuances for devices with eSIM.
Instructions:
- Go to
Settings → Cellular(orMobile communicationsin some localizations). - Turn off the switch Cellular Data** (it will turn grey).
- To completely disable calls and SMS, go to
Settings → Phoneand turn it off Cellular Communications** (if the option is available).
⚠️ Attention: On iPhone with two SIM cards (nano-SIM + eSIM) you'll have to disable the connection for each line separately. Otherwise, the device may automatically switch to the second line if the primary line is unavailable.

3. Method: Using the "Cellular Data Limit" feature
A little-known trick is to limit traffic to zero, which effectively disables mobile internet but leaves Wi-Fi Workers. This method is useful if you need to temporarily block access to 4G/5G without affecting calls.
How to set up:
- 📊 Go to
Settings → Cellular → Data Options → Cellular Data Limit. - 🔄 Turn on the switch Mobile data limit**.
- 📉 Set a limit on 0 MB (or 1 MB if the system does not allow zero).
After this, the mobile Internet will be disabled, but Wi-Fi will continue to work. Calls and SMS will remain active—if you need to disable them as well, combine this method with the previous one.
What should I do if the limit is reset after an iOS update?
In some versions (for example, iOS 17.2) the limit settings are reset after the update. To avoid this, create configuration profile through Settings → General → VPN and device management or use third-party utilities like Shortcuts to apply the limit automatically.
4. Method: Setting up APN to block communication
For experienced users, there's a radical method: changing the APN. If you enter incorrect data, iPhone will lose access to the mobile network, but Wi-Fi will remain untouched. This method is suitable for devices without eSIM (APN blocking on them may lead to activation errors).
Step-by-step instructions:
- 🔧 Go to
Settings → Cellular → Data Options → Cellular Data Network. - 📝 In the field APN Enter a random set of characters (eg.
block123). - 🔄 Save changes and reboot iPhone.
⚠️ Attention: Some operators (eg. MTS or Beeline) automatically restore the correct APN after a few hours. To ensure that the blocking remains permanent, create locked configuration profile with incorrect APN or use Shortcuts to reset the settings periodically.
| Method | Calls/SMS | Mobile Internet | Wi-Fi | Complexity |
|---|---|---|---|---|
| Airplane Mode + Wi-Fi | ❌ Disabled | ❌ Disabled | ✅ It works | ⭐ |
| Turning off Cellular Data | ✅ They work | ❌ Disabled | ✅ It works | ⭐⭐ |
| Mobile data limit (0 MB) | ✅ They work | ❌ Disabled | ✅ It works | ⭐⭐ |
| Invalid APN | ❌ Disabled | ❌ Disabled | ✅ It works | ⭐⭐⭐ |
| Shortcuts (automation) | ⚠️ Customizable | ⚠️ Customizable | ✅ It works | ⭐⭐⭐⭐ |
5. Method: Automation via the Shortcuts app
If you need to switch between modes frequently, create automatic command in the standard application "Teams"** (previously Shortcuts). This will allow you to turn off the connection with a single tap on the icon on the home screen.
How to set up:
- Open the app Teams and press «+» (create a new team).
- Add an action
Set airplane mode(find in search). - Add a second action
Set up Wi-Fiand select "Turn on"**. - Save the command to your home screen or Control center.
Important: In iOS 17, Apple has limited the functionality of some network settings commands. If a command doesn't work, try running it through Automation with a time trigger (for example, “Every day at 20:00”).
