Troubleshooting for TELUS Business customers: Mobile data problems

Common reasons why you are unable to use data on your business mobile device

There are many possible scenarios that can stop your mobile 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.

: 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
