Mobile - Coverage & SIM

If you’re having trouble making or receiving calls, try these steps first:

1. Check your signal. Make sure you have mobile coverage where you are, if not turn on WiFi calling to improve signal through a WiFi connection.
2. Restart your phone Turning your phone off and back on can refresh the connection.
3. Check your account status. Login to MyGoMo to make sure your account is active and up to date.

If calls still aren’t working after this, the issue may be temporary or related to coverage in your area.

If texts aren’t sending or coming through:

1. Restart your phone.
2. Check that you have mobile signal.

If you’re having issues with certain messages (for example, verification codes or premium texts), this may be related to settings on your account.

If mobile data isn’t working:

• Make sure mobile data is turned on in your phone settings.
• Check that airplane mode is turned off.
• Restart your phone.

Indoor coverage can vary depending on your location and building type, so data may work better near windows or outdoors.

If data speeds feel slower than usual:

• Check if you’re in an area with good coverage.
• Restart your phone.
• Close apps running in the background that may be using data.

Mobile speeds can vary depending on location, network demand and signal strength.

WiFi Calling lets you make and receive calls using a WiFi connection instead of the mobile network. It can be helpful if:

• Mobile signal is weak indoors
• Calls drop or sound unclear inside your home

If your phone supports WiFi Calling, you can turn it on or off in your phone settings.

If you’ve tried the steps above and your mobile service still isn’t working as expected you may need to speak to one of our team on chat.

Mobile coverage can vary depending on where you are. Things that can affect signal include:

• Your location (for example, rural areas or indoors)
• Thick walls, basements or metal structures
• Network demand at busy times

If coverage is weaker indoors, moving closer to a window or outside can sometimes help.

You can check mobile coverage by using our coverage map.

Just enter your location to see the expected level of coverage where you live, work or travel. This can help explain why coverage may be stronger in some places than others.

4G Calling allows voice calls to be made over the 4G network instead of older networks. It can improve:

• Call quality
• Call connection times

You can usually turn 4G Calling on or off in your phone settings.

Many newer phones support WiFi Calling and 4G Calling, but compatibility can vary by device.

If these options appear in your phone settings, your phone likely supports them.

• Moving closer to a window
