What is ESIM?How to use your iPhone during long -term stay abroad Recommended for business trips and studying abroad | Time & Space by KDDI

Travel, business trip, study abroad ... I decided to stay abroad for a long time.I want to use a smartphone as usual on the spot.So what should I do?

Until now, when using a smartphone during long-term stay abroad, it is common to rent a Wi-Fi router or buy a local prepaid SIM.

Wi-Fi routers are convenient because they can connect multiple units such as smartphones, tablets, and PCs, but they are luggage, there is a risk of loss, and the disadvantage is that charging is troublesome.In addition, you have to receive and return at the airport, etc., you may be waiting for the procedure, and it is troublesome to forget to return it when you return.If you keep renting for a long time, the price will be high.

The price of the prepaid SIM is attractive, but the risk of loss is also inevitable, it is necessary to unlock SIM, and it takes time to replace the card.There is also a disadvantage that if one terminal is one, when a local SIM is inserted, it is not possible to stand and arrive with a Japanese phone number.

Au's "overseas data ESIM" is a new service that I would like to recommend for iPhone users who are planning to stay in North America for about one week to a month.With the au phone number without replacing the SIM card, local data communication can be used as the second line.If you are staying for a long time, the price is better than the Wi-Fi router, and if you are au users, you do not need to unlock the SIM.

In the first place, ESIM is an indispensable SIM (a card with embedded mobile numbers, etc.), which is indispensable for using a smartphone or mobile phone, is embedded in the terminal body as data.

With au's "overseas data ESIM", even if you go abroad, you do not need to purchase and replace local prepaid SIMs.It can be carried out.It is easy to use even for beginners because it only registers from the app, purchases a plan, and downloads ESIM information.

The target areas are "America", "Canada" and "Mexico" (America Mainland / Alaska / Hawaii / Canada / Mexican / Puerto Virgin Islands * Guam is not eligible).

The target terminal supports dual SIM and iOS 12."IPhone XS", "iPhone XS Max", "iPhone XR" equipped with 1 or later.It can be used even during the au iPhone SIM lock period, and can be used with an iPhone other than au.

The fee for "overseas data ESIM" is 5GB 5,800 yen, 8GB 8,900 yen, which is valid for 30 days.On the other hand, in the case of rental Wi-Fi, around 1,000 yen per day is common.If you stay for a week or more, it's more reasonable than renting a Wi-Fi router.In addition, since it is a fixed amount, you can use it with confidence without worrying about high billing.

If you stay under a week or less, we recommend au's "World Data Statent amount", which can be used for a fixed amount of 980 yen 24 hours.There is no need to rent a device here, and it can be easily set and used using the app.It is automatically disconnected in 24 hours after the start of use, and it is safe that there is no charge until the start button is applied again.

"Overseas Data ESIM" also supports au 24 -hour Japanese support.If you are in trouble with settings at your destination, you can always consult in Japanese.This sense of security is immeasurable in unfamiliar overseas stay.

AU's "overseas data ESIM" is au that can use the usual iPhone overseas as it is, and the price and support are safe.We plan to stay in North America for more than a week for travel, business trips, and study abroad, and if you are a user of "iPhone XS", "iPhone XS Max", and "iPhone XR", there is no way to use it.
