You can use two nano SIM cards from different suppliers in this smartphone, as it is dual SIM-capable. It is important that these are original nano SIM cards, as incompatible cards can damage the device or the SIM card. The device also supports eSIM, which means that you can use eSIM profiles from compatible suppliers in addition to the physical SIM cards. To summarise: You can basically use SIM cards from any supplier as long as they are compatible nano SIM cards or eSIM profiles.

The question of whether a prepaid tariff is possible does not depend directly on the features of the smartphone, but on the tariffs and suppliers you want to use. As a rule, dual SIM mobiles such as the Nokia G42 5G are compatible with prepaid tariffs as long as the supplier supports GSM networks. You should check the availability of prepaid tariffs with your mobile phone provider.
