Troubleshoot data problems
Common reasons why you are unable to use data on your mobile device
In this article
There are many possible scenarios that can stop your data. Please review the troubleshooting tips below to help diagnose and resolve issues you may be experiencing.
Check coverage & signal strength
When the wireless network signal is low, data may stop working or become very slow, while text messages and calls still work. Wireless network signal strength can vary by location due to a number of factors including distance from the nearest cell tower and obstacles in the environment. Check our coverage maps to ensure you are covered by our network.
If you have low signal strength, try moving to a location with better coverage. Concrete and steel buildings may interfere with the reception, especially in elevators and underground locations like basements, subways, and tunnels.
Ensure LTE is activated
If you have a LTE capable device, LTE allows data to travel at a faster speed. LTE is usually enabled by default on devices. Sometimes it can be turned off when travelling internationally, troubleshooting or even simply accidentally changing the setting. Activate LTE to ensure the best possible speeds for your data.
Restart your device
Restarting your device helps clear up minor glitches, just like restarting your computer, often resolves various issues. Power your phone off, wait few seconds, then power it back on. Retry accessing the web.
If your device has a removable battery, remove the battery and put it back in before turning your phone on again.
Activate mobility data for the first time
If you have a new Apple or a non-TELUS device, you may need to ensure the correct settings are setup on device first, before being able to connect to the web. Visit our Activate mobility data section for instructions.
Check that your data is not blocked or disabled
If your account has incurred additional data charges or access to data is disabled, your Data Manager settings in My Account may be blocking your data. Try browsing to a website on your mobile device and see if you’re re-directed to a TELUS block page with more instructions on how to unblock or enable access to data.
Note: Even if Data Access is enabled, the entire account could be blocked from using data due to additional data charges.
For more information on data blocks, view our Data Manager guide.
