Ensuring the phone you have is suitable for Infiniti is half the task, if you wish to also use OmertaNet. It is important you also make sure it supports Electronic SIM cards (or ESIM for short).
ESIM technology means a blank sim is basically built into the devices motherboard. This innovation was driven in part by IoT (Internet of Things) & Smart Watches, whereby a sim card was too big for the devices form factor.
If choosing a handset for Infiniti & you wish to use an ESIM, please check the list below to make sure the technology is supported, as Samsung presently reserves the technology for high end, flagship devices.
