Business Mobile Faults – Frequently asked questions

Fixing common mobile problems

If you’re experiencing problems with your mobile signal, call quality, data speeds, or general device performance, you’re not alone. Many common mobile issues can be resolved quickly with a few simple checks or settings updates. This guide walks you through the most frequent faults our users encounter and provides clear steps to help you get your service back up and running.

If you cannot connect to a network while abroad, try the following steps:

Check your account

Confirm that roaming is enabled on your account and that no roaming bar has been applied
If roaming has worked before and has now stopped, check whether you are in an area with coverage from our partner networks

Try a soft reset

For iPhone (X, 11, 12, 13, 14, 15 series)

Hold the Side button + Volume Up/Down until the power-off slider appears
Drag to power off, then press the Side button to restart

For iPhone (6, 7, 8, SE 2nd/3rd gen)

Hold the Side/Top button until the slider appears
Power off, then press the Side/Top button to restart

For Samsung

Hold Volume Down + Power key until the power options appear
Select Power Off (enter pattern or code if asked)
Restart the device with the Power key

Try a manual roam

For iPhone

Go to Settings > Mobile Data > Network Selection
Toggle OFF Automatic and select a different network
Wait for the connection attempt to fail
Re-select Vodafone (or toggle ON Automatic)

For Samsung

Go to Settings > Connections > Mobile Networks > Network Operators
Turn OFF automatic selection
Choose a different network, leave for 10 seconds
Reconnect to your usual carrier (Vodafone)

If your service is still not working after a spend cap bar has been lifted, try the following:

Refresh your SIM

Turn your phone off, remove the SIM, wait 30 seconds, then reinsert and restart the device

Manual network selection

Go to your phone’s network settings and switch Automatic Network Selection OFF
Choose a different available network, wait until it fails to connect
Re-select your usual network (or turn automatic selection back ON)

Confirm available networks

Check what networks you can see in your phone’s settings
Try connecting to at least two different networks before returning to your normal one

If service is still unavailable after these steps, please contact us so we can investigate further.
