If you are having trouble using data, or if sending/receiving picture and video messages, including instant messaging (for example, iMessage or WhatsApp) isn’t working, data roaming on your device may be switched off.

Data roaming is typically switched OFF by default in your mobile device’s settings. To enable data roaming on your device, follow the device-specific instructions below.

Restarting your phone causes its software to reload, which can fix some problems. To restart your device:

: Press and hold the side button and either volume button until the slider appears. Then drag the slider to turn your device completely off. After the device shuts off, press and hold the side button until you see the Apple logo.

: Hold down the power button on the right side of the device (or on the top of the device for earlier models) until the slider appears. Then drag the slider to turn your device completely off. After the device shuts off, hold the power key until you see the Apple logo.

: If your device does not have a removable battery, completely power off and restart the device.

If you are having trouble using data, or if sending/receiving picture and video messages, including instant messaging (e.g. iMessage or WhatsApp) isn’t working, then you may have a data block active on your device. There are a few ways that a data block may be active on your device.

For more information on how to manage these data blocks, view the support article:

TELUS automatically steers your mobile connection to the roaming partner that should offer the best possible service experience based on your location. However, sometimes you may find that the specific roaming operator is not offering a strong enough signal at a given time due to various reasons (for example, specific geography is blocking the signal, network congestion, etc.).

If there is a specific mobile network operator you want to always stay connected to, you may access the mobile network settings on your device to manually select your mobile network for roaming. When you get back to Canada, ensure you turn your network selection back to automatic to resume your normal service experience. Below are instructions for managing your network operator in your device’s settings.

As of February 22, 2022, AT&T will begin phasing out its 3G/HSPA wireless network service in the U.S. Throughout the year, other U.S. wireless carriers will follow suit. If you're using a mobile device that does not support 4G LTE data and Voice over Long-Term Evolution (VoLTE) roaming, you will not be able to make or receive calls (including 911), send/receive text messages or use data while roaming in the U.S.
