Step-by-Step Troubleshooting Guide

Follow these steps in order to resolve your Tesco Mobile internet issues

Basic Troubleshooting Steps

Start with these simple solutions that fix most internet problems

1

Toggle Mobile Data

Turn mobile data off and then on again to reset the connection. This simple step resolves many temporary data issues.

For iPhone: Settings > Mobile Data > Toggle Mobile Data

For Android: Settings > Network & Internet > Mobile Network > Toggle Mobile Data

Pro Tip: Also try turning off Wi-Fi to ensure your phone is using mobile data, not a weak Wi-Fi connection.
2

Toggle Airplane Mode

Turn on airplane mode for 10-15 seconds, then turn it off. This resets all network connections and can fix data issues.

Note: This will temporarily disconnect all wireless connections including calls and Wi-Fi.
3

Restart Your Device

Completely power off your phone, wait 30 seconds, then turn it back on. This clears temporary glitches and re-establishes connection with the Tesco Mobile network.

4

Check Data Allowance

Verify that you have data remaining on your Tesco Mobile plan. Dial *150# from your Tesco Mobile to check your balance.
