Win10 or Win11 PC with Internet access. Putty and WinSCP installed - see T-Tools for SBC products.
Teltonika RUT955 GSM router package.
SIM card from a local provider. This card is bought by the customer and the customer is also handling all the charges for its use. The plan used must guarantee that SMS sending will not be stopped due to e.g. insufficient funds.
Optionally USB to Ethernet dongle e.g. TP-LINK UE300 to add a second network interface that will be used to configure the B3 SMS device.
If your PC has only one network interafce then you must set it to use DHCP and connect it with the router.
It is convenient to use an USB to Etherent dongle to have the second Ethernet port in the PC used for configuring the router with your Internet connection being intact. Another option is to use WiFi for Internet connection and wired port for connecting the router or vice versa.
