When considering switching to Rakuten Mobile, many people are concerned about the signal strength and reputation. For those people, if you have a dual SIM compatible smartphone, you can add Rakuten Mobile's eSIM to test the signal strength while keeping your current carrier.
What is eSIM? What is Dual SIM?
SIM stands for Subscriber Identity Module Card, and it means "a card that identifies a subscriber." An identification number is recorded on the SIM's IC card, and when this identification number is linked to a phone number, it is activated and communication and phone calls become possible. A SIM is a physical card that can be inserted and removed from a smartphone, but an eSIM has an IC chip built into the smartphone and is integrated with it. If your phone is eSIM-compatible, you can rewrite the identification number online yourself, making the activation process quick and easy.
Benefits of eSIM
・Complete the process from contract to activation online in a short time
・No need to replace SIM cards, so there is less risk of failure
・"Dual SIM" allows you to use multiple lines
With dual SIM, you can use two phone numbers on one smartphone and use them for different purposes. As mentioned below, you can use one phone for calls and the other for data communication.
Benefits of Dual SIM
