Why Your Phone Uses Data on Wi-Fi (And How to Fix It).

2 min. readlast update: 03.22.2024

Sometimes your device might switch to cellular data even when Wi-Fi is available. This is often due to a feature called "Wi-Fi Assist."

What is Wi-Fi Assist?

Wi-Fi Assist automatically uses cellular data when your Wi-Fi signal is weak, boosting your internet connection speed.

When does Wi-Fi Assist turn on?

Wi-Fi Assist might kick in during data-heavy activities like:

  • Syncing Photos
  • Device Backups
  • Software Updates
  • Gaming

How to turn off the Wi-Fi assist feature

If you are on the Tesix Wireless Network Simply Unlimited Plan and worries about exceeding your data allowance, you can turn off the Wi-Fi Assist feature: 


  1. Open the Settings app on your iPhone.
  2. Tap on Cellular or Mobile Data.
  3. Scroll down and locate the Wi-Fi Assist toggle.
  4. Tap the toggle to turn Wi-Fi Assist off (it will turn white when disabled).


The steps to turn off Wi-Fi Assist on Android may vary slightly depending on your device's manufacturer and Android version. Here's a general guideline:

    1. Open the Settings app on your Android phone.
    2. Tap on Connections or Network & internet (depending on your device).
    3. Look for Wi-Fi or Wi-Fi Calling.
    4. Tap on Advanced or Wi-Fi preferences (options might vary).
    5. Locate the Wi-Fi Assist setting (may be called "Auto switch to mobile data" or similar).
    6. Tap the toggle to turn Wi-Fi Assist off (it will be greyed out when disabled).

If you are on the Tesix Wireless Network Beyond Unlimited Plan, keep this feature on to ensure a fast connection when you need.
