Buongiorno, The SIM card is built into the device and I don't think it can be replaced. The connection for the first year is included in the purchase price, thereafter, via the application, it is possible to renew. I can't tell you the cost. SUNRISE appears in the application as a telephone operator. You can try asking SUNRISE for the cost of renewal and check whether there is SUNRISE coverage where you will be using the device. Saluti.

A data SIM card can also be used with this item.
