Sharing Wi-Fi from Your Phone to Your Android Tablet Without a SIM Card: 3 Working Methods

Modern tablets on Android often lack a slot for SIM cards, but they require an internet connection to install apps, watch videos, or sync data. If you have a smartphone with internet access (even without a physical SIM card, thanks to eSIM or connecting to home Wi-Fi), it can be turned into access point for a tablet. However, without a SIM card in the phone, the process has its own nuances, ranging from operator restrictions to firmware specifics.

In this article we will analyze all possible scenarios: mobile internet distribution (if the phone supports it) eSIM), rebroadcasting home Wi-Fi via a smartphone, and using a USB cable or Bluetooth for data transfer. We'll focus on the issues users encounter. Android 12+, where Google has tightened its SIM-free internet tethering rules. You'll learn how to bypass these blocks, which settings to check first, and why your tablet might not see your phone's network.

Spoiler: on some phones (eg Samsung Galaxy S22+ With One UI 5.1, Wi-Fi sharing without a SIM card is blocked at the firmware level, but there is a workaround via USB tethering.

1. Is it possible to share Wi-Fi from a phone without a SIM card?

Technically Yes, but with some caveats. Everything depends on three factors:

1. Internet source on the phone (mobile data, Wi-Fi, Ethernet adapter).
2. Smartphone manufacturer policies (e.g. Xiaomi And Huawei (SIM-free distribution is often blocked).
3. Versions Android: starting from Android 12Google has introduced restrictions on Wi-Fi sharing via hotspots.

Let's look at possible internet sources on your phone that can be shared:

• 📶 Mobile Internet without SIM: only if the phone supports eSIM (For example, Google Pixel 7 or iPhone 14) and you have an activated tariff. In Russia eSIM officially supported MTS, Beeline And Tele2.
• 📡 Connecting to another Wi-Fi: The phone receives internet from the router and then relays it to the tablet. This feature does not work with all firmware versions (see table below).
• 🔌 Ethernet via adapter: if a USB-Ethernet adapter is connected to the phone (for example, for Samsung DeX), the Internet can be distributed via Wi-Fi.
• 🤝 USB modem or Bluetooth: alternative methods if Wi-Fi distribution is blocked.

⚠️ Attention: On phones with Mediatek-processors (for example, Redmi Note 11) SIM-free Wi-Fi sharing is often disabled at the kernel level. Check your device model in Settings → About phone → Model.

2. Method 1: Sharing Wi-Fi from a phone connected to another Wi-Fi (relay)

If your phone is connected to your home or office Wi-Fi, you can try rebroadcasting that signal to your tablet. This will only work if two conditions are met:

1. On the phone Android versions below 12 or The manufacturer's firmware allows retransmission (for example, ColorOS on Oppo Reno).
2. The router does not block "bridges" between devices (the parameter must be disabled in the router settings) AP Isolation).

Setup instructions:

1. Connect your phone to the original Wi-Fi network.
2. Open Settings → Connections → Hotspot & Tethering (on Samsung) or Settings → Network & Internet → Access Point (in pure Android).
3. Select Wi-Fi hotspot and activate it.
4. On your tablet, connect to the new network (the name will match the name of your phone's access point).

If the Internet does not appear on your tablet after activating the hotspot, check:

• 🔄 IP conflicts: the phone and tablet must have different IP addresses (checked in Settings → About phone → Status).
• 🔒 Firewall: some antiviruses (for example, Kaspersky) block retransmission.
• 📶 Wi-Fi channel: if the phone and the router are operating on the same channel (for example, Channel 6), interference may occur. Change the channel in the access point settings.

⚠️ Attention: On Android 13 and newer Wi-Fi relaying via an access point is blocked for most devices due to policy GoogleIf your phone has been updated to a new version, this method will not work - use USB modem.

3. Method 2: Sharing the Internet via USB (modem mode)

If Wi-Fi distribution is blocked, the most reliable method - connecting the tablet to the phone via USB cable in modem mode. This method works even without a SIM card, if the phone has any internet source (Wi-Fi, eSIM or Ethernet).

Step-by-step instructions:

1. Connect your phone to your tablet using USB-C/USB-A cable (an adapter may be required).
2. On your phone, go to Settings → Connections → Hotspot & Tethering (or similar section).
3. Activate the option USB modem.
4. On your tablet, in the connection settings, select USB Internet (may be called RNDIS).

Advantages of the method:

• ⚡ Stable connection: no packet loss like with Wi-Fi.
• 🔋 Battery saving: The phone uses less battery than when distributing over the air.
• 🛡️ Security: data is transmitted over a wire and cannot be intercepted.

Possible problems and solutions:

4. Method 3: Sharing via Bluetooth (Wi-Fi alternative)

If neither Wi-Fi nor USB are suitable, the only option left is Bluetooth modemThis method is slower (speed up to 3 Mbps), but works on all phones without a SIM card and does not require cables.

How to set up:

1. Turn on Bluetooth on your phone and tablet.
2. Pair the devices: On your phone, select the tablet from the list of available devices and confirm the code.
3. On your phone, go to Settings → Connections → Hotspot & Tethering and activate Bluetooth modem.
4. On your tablet, in the Bluetooth settings, tap on the phone's name and select Connect to the Internet.

Limitations of the method:

• 🐢 Low speed: suitable only for instant messengers and lightweight websites.
• 🔋 High battery consumption: Bluetooth and modem simultaneously discharge the phone in 2-3 hours.
• 📱 Limited compatibility: on some tablets (eg. Lenovo Tab M10) option Connect to the Internet may be absent.

Why is my Bluetooth modem slow?

Speed ​​is limited by the Bluetooth protocol version. Even with Bluetooth 5.0, the maximum data transfer rate is ~3 Mbps (versus 50+ Mbps for Wi-Fi 5). Furthermore, the protocol introduces latency due to packet inspection.

5. Problems and errors: what to do if nothing works

If none of the methods worked, check these common causes:

• 📵 "The access point does not turn on.": on phones Huawei And Honor Without a SIM card, this option is often hidden. Solution: insert any inactive SIM card (even without a plan) or use HiSuite to unlock.
• 🔄 "Connected, but no internet": reset the network settings on your tablet (Settings → System → Reset → Reset Wi-Fi, mobile networks, and Bluetooth).
• 🔒 "A password is required, but there is none.": on some phones (eg. Realme) the access point password is reset after a reboot. Check it in Settings → Access Point → Access Point Settings.
• 📱 "The tablet doesn't see the network.": if the phone distributes Wi-Fi at a frequency 5 GHz, and the tablet only supports 2.4 GHz, change the range in the access point settings.

For diagnostics use ADB commands (requires enabled) USB debugging):

adb shell settings put global tether_dun_required 0
adb shell settings put global tether_entitlement_required 0

These commands disable checking for Internet sharing rights (not available on all firmware versions).

⚠️ Attention: On phones with Android 14 And One UI 6.0 (For example, Samsung Galaxy S23) Wi-Fi sharing without a SIM card is completely blocked at the software level. The only workaround is to use USB modem or purchase of external 4G modem.

6. Alternative solutions: if your phone can't distribute the Internet

If all attempts to share the Internet from a SIM-less phone have been unsuccessful, consider these options:

• 📡 External 4G modem: devices like Huawei E5577 or TP-Link M7350 They distribute Wi-Fi without being tied to a phone. Prices start at 2,000 rubles.
• 🔌 Powerline adapters: if you have access to an outlet with internet access (for example, via router), adapters TP-Link AV600 will transmit a signal through electrical wiring.
• 📶 Public Wi-Fi networks: Cafes, libraries, and shopping malls often have free Wi-Fi. Use a VPN (e.g. ProtonVPN) for safety.
• 📱 SIM card for tablet: if your tablet supports nano-SIM (For example, Samsung Galaxy Tab S6), buy a separate SIM card with an unlimited tariff.

FAQ: Frequently Asked Questions

Is it possible to share Wi-Fi from a SIM-less phone if it is connected to the internet via a USB-Ethernet adapter?

Yes, but only if the phone supports it. Ethernet → Wi-Fi relay mode. This works on most flagships (Samsung Galaxy S/Note, Google Pixel) and some devices with Qualcomm SnapdragonCheck your access point settings: if there is an option there Source: Ethernet, then distribution is possible.

On Mediatek-phones (for example, Redmi 9A) this feature is usually absent.

My tablet connects to my phone's hotspot, but it says "No internet access." What should I do?

The reasons may be different:

1. DNS error: manually enter DNS on the tablet 1.1.1.1 (Cloudflare) or 8.8.8.8 (Google).
2. Operator blocking: If the phone is connected to the mobile Internet, the operator may prohibit retransmission (for example, Megaphone blocks distribution on tariffs without the "Modem" option).
3. IP conflict: disable the option on your tablet IPv6 in the Wi-Fi settings.

Also try change network mode on your phone: go to Settings → Mobile network → Network type and select LTE only (Sometimes 3G blocks distribution).

How to share Wi-Fi from an iPhone to an Android tablet without a SIM card?

On iPhone (even without a SIM card) you can share Wi-Fi if it is connected to another network:

1. Connect iPhone to Wi-Fi.
2. Go to Settings → Tethering and turn it on Allow others.
3. On your tablet, connect to the network named iPhone ([your name]).

Restrictions:

• On iOS 16+ Wi-Fi relaying only works if the source network has internet access (for example, it is not suitable for guest networks with authorization).
• Android- tablets sometimes don't connect to the access point iPhone due to different encryption standards. In this case, iPhone change the security type to WPA2 V Settings → Personal Hotspot → Wi-Fi Password.

Why did Wi-Fi hotspot stop working after updating Android?

Starting from Android 12, Google introduced restrictions on Wi-Fi retransmission via an access point (Wi-Fi Sharing). Manufacturers also add their own locks. For example:

• Samsung (One UI 4.0+): SIM-free sharing is only possible via USB.
• Xiaomi (MIUI 13+): You need to insert a SIM card (even an inactive one) to unlock the option.
• Huawei (EMUI 12+): Wi-Fi relay is completely disabled.

Solutions:

1. Roll back to an older firmware version (risky, may damage your phone).
2. Use USB modem or Bluetooth.
3. Install custom firmware (for example, LineageOS), if your phone is supported.

Is it possible to share Wi-Fi from a phone to a tablet without root access?

Yes, in most cases root is not requiredHowever, there are exceptions:

• If the manufacturer has blocked distribution at the software level (for example, Huawei without SIM), it is impossible to bypass this without root.
• On Android 10 and newer, some features (such as changing regional settings to bypass blocking) require root.

Alternatives to root:

• Use ADB commands (see the section on errors).
• Connect your phone to Linux-to the computer and set up retransmission via iptables.
• Buy an external modem (for example, ZTE MF823), if the distribution is critically important.
