The first smart phone that uses eSIM. eSIM’s ability is superior than physical SIM card due to the fact that in 1 eSIM can contain up to 5 dtac numbers, suitable for customers that collect beautiful and lucky numbers in 1 device.

The obvious benefits of eSIM is to create more than 1 eSIM profile in a device. For instance, eSIM for iPhone11, 11 Pro, 11 Pro Max and above can add to maximum of 5 eSIM(profile) but iPhone allows you to use only 1 at a time, suitable for various Pack Plans users.
