Method 1: Standard mobile hotspot (the easiest)

This is a basic method that works out of the box. It's suitable for one-time internet sharing with 1-2 devices (laptop, tablet). The main drawback is connection limit (usually 5-8 devices, depending on the operator).

How to enable:

  • 📱 Open Settings → Connections → Mobile Hotspot & Tethering
  • 🔄 Toggle the slider Mobile Hotspot to the "On" position
  • ⚙️ Click Setting up a mobile hotspotto change:
    • Network Name (SSID)
    • Password (minimum 8 characters)

Number of devices up to 8 unlimited (via hub)
Latency (ping) 20-50 ms 10-30 ms

Method 3: Sharing via Bluetooth (saving traffic)

This is the most economical way in terms of battery and traffic consumption, but with limited speed (up to 3 Mbps). Suitable for:

  • 📱 Smartwatch connections (Galaxy Watch, Apple Watch)
  • 🎧 Headphones with internet connection support
  • 🚗 Car multimedia systems (for example, Android Auto)

Step-by-step setup:

  1. Turn on Bluetooth on both devices.
  2. On Samsung A71 go to Settings → Connections → Bluetooth.
  3. Select the device to connect to and confirm the pairing.
  4. Return to Settings → Connections → Mobile Hotspot & Tethering.

On the device you are connecting to (for example, a laptop), select Connecting via an access point in the Bluetooth settings. If the option doesn't appear, update the Bluetooth drivers on your PC.

Why is my Bluetooth modem slow?

The speed is limited by the Bluetooth 5.0 standard (max. 3 Mbps). For comparison, 5 GHz Wi-Fi offers up to 433 Mbps. However, Bluetooth consumes 5-7 times less power, making it convenient for background tasks (for example, syncing messages on a smartwatch).

Method 4: Optimize your hotspot for speed and battery life

By default Samsung A71 distributes Wi-Fi in mode 802.11n (up to 150 Mbps). To increase speed and reduce battery consumption, adjust these settings:

  • Go to Settings → Connections → Mobile hotspot and tethering → Set up a mobile hotspot.
  • Select Band: 5 GHz (if option is not available, see solution below).
  • Set the channel manually (recommended) 36, 40 or 44 - they are less busy).

2. Limit the number of connected devices:

  • In the same hotspot settings, find the option "Max. number of connections".
  • Set value 2-3 (the fewer devices, the more stable the connection).

3. Turn off Intelligent Wi-Fi (if not needed):

This feature automatically switches devices between mobile data and Wi-Fi, but may cause delays. To disable:

Settings → Connections → Wi-Fi → ⋮ (menu) → Advanced → Intelligent Wi-Fi → Off

Method 5: How to enable 5GHz if the option is unavailable

If there is no option in the hotspot settings 5 GHz, the problem may be in:

  • 📵 Operator restrictions (most often at Tele2 And Iota)
  • 🔧 Regional phone settings
  • 🛠️ Outdated firmware

Solution 1: Change region

  1. Go to Settings → General → Device Management → Region.
  2. Select a country where 5 GHz is allowed (e.g. USA or Germany).
  3. Restart your phone and check for the option. 5 GHz in a hot spot.

Solution 2: Manual configuration change (requires root)
