Connect to the internet
Use the arrows on your SumUp 3G to open and scroll through the menu, selecting "Device settings" with the green tick.
Select "Connection type" and then "Wi-Fi".
If Wi-Fi is switched off, select "On" to turn it back on. Your device will now scan for known networks.
If your device doesn't connect automatically, select "Search networks" and choose a network.
Enter the Wi-Fi password and use the green tick to confirm.
Restart your device with the power button on the side or try moving to an area with better connectivity, such as open areas, near windows or closer to your Wi-Fi router.
