Android does not connect to the iPhone in modem mode: a complete analysis of the reasons and solutions

The problem when the Androiddevice refuses to connect to iPhone in modem mode is familiar to many users. It would seem that both systems support the standard protocol Wi-Fi Hotspot, but in practice the connection often fails, the devices “do not see” each other or display an authentication error. In 80% of cases, it is not hardware faults that are to blame, but software conflicts between iOS and Android —especially after security updates from Apple.

The situation is complicated by the fact that Apple actively blocks “non-standard” connections to its access points, considering them potentially dangerous. And Android, in turn, can ignore networks with atypical encryption settings. In this article we will look all possible reasons from trivial errors in settings to hidden restrictions of telecom operators. You will receive step-by-step guide for each of the 7 main problems, and also learn how to bypass restrictions iOS 17+ on connecting third-party devices.

If you have already tried rebooting both phones and it did not help, do not rush to reset the settings. In 95% of cases, the problem is solved without radical measures. Let's start with the simplest and gradually move on to complex settings.

1. Checking the basic connection conditions

Before digging deep into the settings, make sure that you have completed minimum requirements to create an access point. Often, users miss obvious points, because of which Android simply cannot “see” the network from iPhone.

First, check what is on iPhone mobile data is turned on. Without an active connection to the operator's network, the access point will not work. Go to Settings → Cellular → Data settings and make sure that the switch Cellular data is active. Also pay attention to the signal indicator in the upper right corner of the screen - if it is gray (and not green/blue), the Internet is turned off.

Secondly, make sure that on iPhone allow connection of other devices. B iOS 16+ Apple added additional protection: by default, the access point can only be visible to those devices that have already connected to it before. To reset this filter:

1. Open Settings → Modem mode
2. Click on Wi-Fi password
3. Tap at the bottom of the screen Reset network settings (this will not delete your data, only the list of known devices)

Finally, check tariff limits. Some operators (for example, MTS or Beeline) block the distribution of the Internet on tariffs with limited traffic. Since 2023, many Russian operators began to equate traffic from modem mode to “premium” services, even if you have an unlimited tariff.

2. Wi-Fi settings conflict between iOS and Android

The most common cause of problems is that by default it creates an access point with settings that not all incompatibility of network parameters. iPhone by default creates an access point with settings that are not all Androiddevices can process correctly. We are talking about three key parameters:

1. Security type: Android 9 and below section. iPhone always uses WPA3 Personal the most secure, but not the most compatible protocol. Old smartphones Android 9 and below may not support WPA3 or connect with errors. Solution:

• 🔄 On iPhone go to Settings → Tethering mode → Wi-Fi password
• 🔒 In the section Security select WPA2/WPA3 Personal (hybrid mode)
• 📱 On Android in the Wi-Fi settings, enable the option Improved compatibility (if available)

2. Wi-Fi frequency. iPhone 12 and later By default, the Internet is distributed at a frequency 5 GHz, which provides high speed but has a shorter range. Many budget Androidsmartphones (for example, Redmi or Samsung A-series) have poor reception 5 GHz at a distance of more than 3 meters. To force a switch to 2.4 GHz:

Settings (iPhone) → Modem mode → Max. compatibility → Enable

3. Password length. iOS automatically generates a password of 8 characters, but some versions Android (especially with custom firmware) require a password of length minimum 10 characters. Try manually setting a password like 1234567890 (without Cyrillic and special characters!).

3. Telecom operator restrictions: hidden blocking

Many users do not suspect that their telecom operator can purposefully block distribute the Internet to other devices. This applies not only to budget tariffs, but also to some “unlimited” offers. Here's how it works:

Since 2022, large operators (Megafon, Tele2, Iota) began to divide traffic into:

• 📱 Main traffic (for phone)
• 🔄 Modem mode traffic (for distribution)

At the same time, in many tariffs traffic for distribution is either limited or completely blocked. For example, in Tele2 on the "My Unlimited" tariff, Internet distribution is available only after connecting the "HotSpot" option for +150₽/month.

How to check does the operator block the distribution:

1. Call the hotline (for example, *111# for MTS) and check the tariff conditions.
2. Try to connect to the access point from another iPhone —if it works, the problem is Android.
3. Install the iPhone application Speedtest and check the Internet speed in modem mode. If it is below 1 Mbit/s, the operator is almost certainly limiting the traffic.

In 2026 Roskomnadzor obliged operators to clearly indicate Internet distribution terms and conditions in contracts. However, in practice, this information is often hidden in the “special conditions” of the tariff. If you find a blocking, demand a recalculation of payments for an unprovided service (grounds: Article 10 of the Law "On Protection of Consumer Rights").

4. Software conflicts: updates, betas and custom firmware

If the connection worked before, but after the update iOS or Android it stopped, it's your fault software conflicts. This is especially true for:

• 📱 iPhone with iOS 17.2+ (a new authentication protocol has been introduced)
• 🤖 Android 14 with functions Private DNS or MAC Randomization
• 🛠️ Devices with custom firmware (LineageOS, MIUI for Xiaomi)

B iOS 17.4 Apple has added a function Wi-Fi Password Sharingthat may conflict with Android. To disable its:

Settings (iPhone) → Apple ID → iCloud → Passwords and keys → Disable "Network sharing"

On the side Android Problems are often caused by:

1. Private DNS: Open Settings → Network and Internet → Private DNS and select Automatic.
2. Adaptive battery: Settings → Battery turn off optimization for the application Wi-Fi.
3. VPN applications: Even turned off VPNs (for example, 1.1.1.1 or ProtonVPN) may block the connection. Remove them temporarily.

If you have Xiaomi, Realme or Oppocheck the settings Double applications or Second space —they can create virtual networks that conflict with the access point.

5. Hardware problems: antennas, modules and overheating

If software methods do not help, it is worth checking hardware. Most often, problems are caused by:

1. Wi-Fi module malfunction on iPhone. This is true for devices that have been dropped or come into contact with water. You can check the module like this:

• 📶 Try connecting to another Wi-Fi network (for example, a home router). If it doesn't work, the module is damaged.
• 🔍 Turn on modem mode and see if the network appears in the list of available ones on another device (even if you cannot connect).

2. Processor overheating. iPhone automatically turns off Internet distribution at temperatures above 45°C. This is a common problem for iPhone 11/12 in cases or in direct sunlight. To check:

1. Open the application Aida64 (or similar) on Android.
2. Bring iPhone to the temperature sensor (if any).
3. If the temperature is above 40°C, let the device cool down 10-15 minutes.

3. Conflict between Bluetooth and Wi-Fi. On some Androiddevices (for example, Samsung Galaxy S22+), simultaneous operation of Bluetooth and Wi-Fi in modem mode leads to failures. Disconnect Bluetooth on both devices before connecting.

6. Alternative connection methods: USB and Bluetooth

If the connection via Wi-Fi did not work, try alternative methods. They are less convenient, but often save in critical situations.

1. Connection via USB (USB-tethering). data-i="263">📱 On

• ⚡ Suitable for devices with a connector Lightning (iPhone) And USB-C (Android).
• 🔌 Original cable required Apple (Chinese analogues may not work).
• 📱 On iPhone turn on Modem mode → Allow other devices to connect via USB.

⚠️ Attention: On Android 12+ may need to be turned on USB debugging v Settings → System → For developers. This will temporarily reduce the security of the device.

2. Connection via Bluetooth

1. On iPhone turn on Bluetooth and Modem mode.
2. On Android in settings Bluetooth find iPhone and pair the devices.
3. In the list of networks on Android a network should appear with your name iPhone and icon Bluetooth.

The speed will be lower (~1-2 Mbit/s), but this is enough for instant messengers and mail.

3. Using third-party applications

If standard methods do not work, try applications like PdaNet+ or ClockworkMod Tether. They bypass operator restrictions, but require rootrights to Android or jailbreak on iPhone.

⚠️ Attention: Using such applications may violate the terms of your tariff. The operator has the right to block the SIM card for “unauthorized distribution of traffic.”

7. Extreme measures: resetting settings and contacting support

If none of the above helped, radical methods remain. Start with soft reset:

Resetting network settings on iPhone:

Settings → General → Transfer or reset iPhone → Reset → Reset network settings

This will delete all saved ones Wi-Fi networks and VPN, but will not affect personal data.

Resetting Wi-Fi settings on Android:

Settings → System → Reset → Resetting Wi-Fi, mobile network and Bluetooth settings

If this doesn’t help, you’ll have to do it full reset. But before that:

• 📱 Back up your data on both devices.
• 🔍 Check if the warranty is valid (a reset may void it).
• 📞 Contact support Apple (8-800-555-6734) or your operator.

In 5% of cases the problem lies in firmware of the operator's base station. For example, in 2023, users Beeline in Moscow massively complained about failures in modem mode due to hardware updates. In such cases, all that remains is to wait for a fix from the operator.
