Modern smartphones have long since ceased to be mere communication devices—they've become full-fledged internet access points. Situations where you urgently need to share mobile data with another phone arise regularly: from a lack of Wi-Fi in a cafe to the need to connect a tablet to the internet while traveling. However, not everyone knows how to properly set up internet sharing to avoid security issues or an unstable connection.
In this article, we will take a detailed look at all the ways to share the Internet between phones via Wi-Fi - from standard functions Android And iOS to alternative methods for devices with limited capabilities. You will learn how to enable modem mode, which settings optimize speed, and what to do if the second phone can't detect the network or connects but the internet isn't working. We'll also reveal little-known tips that will help you save battery life and avoid unnecessary mobile data charges.
Why is Wi-Fi internet sharing better than other methods?
There are several ways to transfer the Internet from one phone to another: via Bluetooth, USB cable or Wi-FiThe latter option remains the most popular—and for good reason.
Firstly, Wi-Fi provides the highest data transfer speed of all wireless methods.If your plan supports 4G or 5G, sharing via Wi-Fi will allow the second device to use almost all of the available bandwidth. By comparison, Bluetooth is limited to 2-3 Mbps, which is insufficient even for watching HD video.
Secondly, Wi-Fi allows you to connect multiple devices simultaneously (usually up to 5-10), while Bluetooth and USB only support a single connection. This is convenient if you need to share the internet not only with your phone, but also with a laptop or tablet.
- 📶 Speed: up to 100 Mbps (depending on the tariff and phone model)
- 🔗 Number of connections: up to 10 devices simultaneously
- 🔋 Power consumption: moderate (less than when using Bluetooth)
- 🛡️ Safety: supports WPA2/WPA3 encryption
The only drawback of Wi-Fi is its higher power consumption compared to USB tethering. However, this can be easily mitigated by following the tips in our article.
Preparing your phone for Wi-Fi sharing: Checking key parameters
Before enabling tethering, make sure your phone is ready to share the internet. Skipping this step often leads to connection issues or network instability.
The first thing to check is - availability of mobile Internet on your main phone. Make sure that:
- 📱 Mobile data is enabled (
Settings → Connections → Mobile networkson Android orSettings → Cellularon iPhone) - 📶 There is a stable signal (at least 2-3 bars on the network indicator)
- 💰 There are sufficient funds in your account (some operators block distribution if your balance is negative)
Second - battery statusSharing Wi-Fi increases energy consumption by 20-40%. If the charge is below 30%, it is better to connect the phone to a charger or use power saving mode (but please note that this may limit your internet speed).
| Parameter | Minimum requirements | Recommendations |
|---|---|---|
| Signal level | 1 division (EDGE/3G) | 3-4 divisions (4G/5G) for stable operation |
| Battery charge | 10% | More than 50% or connected to charging |
| Tariff plan | Anyone with mobile internet | Unlimited or with a large traffic package |
| Android/iOS version | Android 5.0 / iOS 8 | Android 10+ / iOS 13+ for better stability |
⚠️ Attention: Some operators (eg. Tele2 or Iota) may block internet tethering on certain plans or charge additional fees. Check the terms in your personal account or with your operator.
How to Share Wi-Fi from an Android Phone: Step-by-Step Instructions
The process of enabling modem mode on Android may vary slightly depending on the OS version and phone manufacturer (Samsung, Xiaomi, Huawei etc.). We will consider a universal method that works on 90% of devices.

Turn on Wi-Fi(can also be turned onBluetoothorUSB)
An important nuance for owners iPhone: If the second phone cannot connect, check if it is turned on Mobile data limit (Settings → Cellular → Data Options → Mobile Data Limit). This feature can block connections to other people's access points.
⚠️ Attention: On iPhone with dual SIM card (eSIM + nano-SIM) the modem mode will use the SIM card that is selected for data transfer in Settings → Cellular → Cellular Data.
Also note that Apple Automatically disables tethering if no device is connected for 90 seconds. To avoid this, connect at least one device or enable the option Maximize compatibility in the modem settings (available on iOS 13 and later).
How to connect to a shared Wi-Fi hotspot from another phone
Now that the hotspot is active, all that's left is to connect the second phone. The process is almost the same for Android And iOS, but there are a few important details that will ensure a stable connection.
On the second phone, follow these steps:
- Open
Settings→Wi-Fi - Make sure Wi-Fi is turned on (slider in position
On) - In the list of available networks, find the access point name (the one you set on the first phone)
- Tap on the network name and enter the password
- Confirm connection
If the network does not appear in the list:
- 🔄 Update the list of networks (pull the list down or click
Refresh) - 📶 Check the distance — the maximum distance for a stable connection is ~10 meters
- 🔋 Restart both phones - this helps with temporary failures
- 🛠️ Check your network settings on the first phone (maybe turned on
Hidden SSID)
On Android- a notification may appear on phones after connection "The Internet may not be secure."This is a standard warning that you're connected to a network without encryption (if you haven't set a password) or with an older security type. If you're confident in the strength of your password, you can ignore this message.
What to do if there is a connection, but the Internet does not work?
If the second phone is connected to Wi-Fi, but pages won't open, check:
1. APN settings on the main phone (must meet operator requirements).
2. Background limitations - some applications (for example, YouTube or Netflix) may block playback when sharing the Internet.
3. Firewall or VPN - disable them on both devices.
4. Power saving mode - It can limit background data transfer.
Optimizing Wi-Fi Sharing: How to Increase Speed and Reduce Battery Drain
Even if you've successfully connected your second phone, your internet speed may be slower than expected, and your primary device's battery may drain too quickly. Here are a few proven ways to optimize your hotspot.

FAQ: Frequently asked questions about sharing Wi-Fi from your phone
Is it possible to share Wi-Fi if your phone doesn't have a SIM card?
No, to share your mobile data, you must have an active SIM card with a data plan. However, if you have access to another Wi-Fi network (for example, your home network), you can share it using the Shared Wi-Fi feature. Repeat Wi-Fi (available on some models) Xiaomi And Huawei).
How much traffic is used when distributing Wi-Fi?
Data usage depends on activity on the second phone. Approximate usage:
- 📱 Social networks (VK, Instagram): ~50-100 MB/hour
- 🎵 Music (Spotify, YouTube Music): ~70-150 MB/hour
- 🎬 Video (YouTube 720p): ~500-700 MB/hour
- 🎮 Online games: ~40-100 MB/hour
To control your consumption, use the built-in traffic counter (Settings → Network & Internet → Data Usage → Data Usage on Android).
Is it possible to share Wi-Fi from phone to phone without a password?
Technically yes, but it's extremely insecure. Leaving the network open (without a password) will allow unauthorized devices to connect, which will lead to:
- 🛡️ Traffic theft (Your tariff may be exhausted quickly)
- 🔍 Risk of hacking (attackers can intercept data)
- 📵 Slowing down work (many connections = low speed)
On Android You can enable an open network in the access point settings by selecting There is no security, but we strongly advise against doing this.
Why might an operator block Wi-Fi distribution?
Some operators limit or block Internet distribution for the following reasons:
- 📜 Tariff conditions: The contract may prohibit the use of the telephone as a modem.
- 💰 Additional fee: Distribution may be charged separately (for example, 50 rubles/day).
- 📡 Network congestion: The operator may limit distribution during peak hours to reduce the load.
- 🔒 Unlimited tariffs: Often, "unlimited" only applies to the phone, and data sharing is limited (for example, 10 GB per month).
To clarify the terms, call the operator or check your personal account.
How to share Wi-Fi from phone to phone if the main phone does not support this function?
If your phone doesn't support Wi-Fi (very old models), you can use alternative methods:
- 🔗 Bluetooth modem: slower, but works on all phones. It turns on in
Settings → Connections → Bluetooth modem. - 📎 USB cable: suitable for Android-phones. You need to connect the cable and turn it on.
USB modemin the settings. - 🖥️ Via PC: Connect both phones to the computer and share the Internet through
General access(on Windows this is done throughNetwork and Sharing Center). - 📡 External router: some portable routers (eg TP-Link M7350) can receive a signal from a phone via USB and distribute it via Wi-Fi.
The most versatile option is Bluetooth, but the speed will be severely limited.
