Make sure cellular is enabled on the payment terminal : Go to the Android settings (pwd pax9876@@) → More → Cellular Networks → click the check box near “Data roaming”
Make sure that 3G/4G is not selected as the preferred network in the device settings. You can check it by going to device settings (pwd: pax9876@@) Wireless —> Networks —> Mobile networks —> Preferred network type —> 4G preferred (These steps may vary a bit depending on the version of PAX used).
Make sure that the SIM APN settings are correctly set up on the terminal, if using the Handpoint sim cards (soracom), go to device settings (pwd: pax9876@@) Wireless —> Networks —> Mobile networks —> Advanced → APNs
Enter the following APN settings
Name - any name you choose.
APN - soracom.io
Username - sora
Password - sora
Ask Handpoint to manually activate the sim card on their end in the Soracom portal
Once confirmation is received from Handpoint, restart the terminal. Upon restart the terminal should be connecting to Restart the terminal, upon booting the terminal should now work via cellular.
Make sure that the SIM inserted in the terminal still has data available for transactions.
If the merchant has a not very reliable WiFi, perhaps the best option would be to forget the WiFi network to prevent the device from connecting to this network since the PAX considers Wifi as primary before the SIM card connection. Forgetting the merchant's known network, the device will only use the SIM card, ensuring a better internet connection.
Connect the terminal to a mobile hotspot (from a phone) to make sure that the terminal is able to get an internet connection even though cellular (SIM) connection does not work properly.
