I also use pocket Wi-Fi when I go back to Japan \ (rental)}
and my cell phone does not have phone functionality in Japan, so if I want to contact someone, I use line or messenger.

I also rent wifi, but it is much cheaper to rent online from a Japanese wifi rental company than to rent in Hawaii.

I also rent wifi from Rakuten in Japan every time. They deliver to my accommodation and I can return it at the airport post on the way back. When I need to make a phone call, I use a public phone. You don't see many public phones these days, but you can search NTT to find the nearest public phone location. You can also use the goo disaster prevention app to find the location of a pay phone.

I will stay in Japan for a short period of time using a SIM card.

I have arranged for it to be delivered to my home after I return to Japan.

I can't use my mobile number, but I can use Wifi outside my home.

If you stay less than 1 month, pocket Wifi is useful because it is heavy.

What I have done in the last few times is

1. buy a data SIM card for Japan from Amazon in the US
2. buy a data SIM card for Japan from Amazon in Japan and send it to a family member, who will mail it to me

Both 1 and 2, call If I need to talk, I will do it via data with an app.
The trip was 2 weeks, so not a lot of data.

1. has the advantage that you can buy it here, but it is more expensive per data.
2. has the advantage that you can buy a SIM card at a reasonable price by taking advantage of the weak yen, but there is a hassle of having it sent from Japan.
In my case, I bought it 1-1 month before my trip by regular mail ・ and had it sent to me.

In both cases, I replaced the card on the plane to Japan and was able to connect to the internet as soon as I arrived at the airport.

I hope this helps.

Related question.

I am thinking of buying a data SIM card for Japan from Amazon in Japan. if I use the SIM card, I cannot make phone calls, but I can connect to the internet and make LINE calls, and my phone number will not change. Is it correct to think that ？?

LoveKihei,

Thank you for your compliments.
Even if you can do little things in daily life by yourself if you know what is convenient, you may be a little confused and think a little at first.
I think it would be ideal to have a bulletin board where we can ask each other questions and help each other ～ at such times.
I look forward to your continued support.

#9 LoveKihei,

My phone is the type that only allows one SIM card to be inserted,
so when I switch to a Japanese data SIM card, my Hawaii number is disconnected.
Also, you will not get a Japanese phone number.
Other than that, as you said, you will be able to connect to the internet and make calls on LINE and Messanger.
In addition, by inserting a SIM card here when you come back to the U.S., you will be able to use U.S. numbers.

However, if you have a phone with two SIM cards, or if you have an eSIM and a physical SIM card that can support dual SIM,
you may still be able to use your US phone number while in Japan.
This is because some carriers allow you to make and receive calls ・ and texts over WiFi, and some plans allow you to make and receive calls
and texts abroad ・ for an additional fee.

If you prefer to use your US phone number in Japan as well,
you can ask for the carrier, plan, and phone model and they may be able to help you.

Thanks for the quick information. My phone is an iPhone 11 64GB. Like Mr. Koji, I can only insert one SIM card. Just yesterday I changed my contract to SPECTRUM and now I have eSIM. I would appreciate it if you could let me know if it is possible to use an eSIM and a physical SIM card to support a Dual SIM, as Koji-san said. If I can't use my US phone number while in Japan, I don't think it will be a problem, so I am planning to buy a data SIM card for Japan from Amazon in Japan. Thank you for your continued support.

LoveKihei,

I'm an android user myself and iPhone is a bit of a challenge, but
according to the Apple information below, iPhone 11 will have dial support with eSIM and physical SIM.
（ My phone does not support eSIM （ crying ） ）

https://support.apple.com/ja-jp/guide/iphone/iph9c5776d3c/ios#:~:text=%! E4%BB%A5%E4%B8%8B%E3%81%AE%E3%83%A2%E3%83%87%E3%83%AB%E3%81%A7%E3%81%AF%E3%80%81%E3%83%87%E3%83%A5%E3%82%A2%E3%83%AB,eSIM%E3%82%92 %E4%BD%BF%E7%94%A8%E3%81%A7%E3%81%8D%E3%81%BE%E3%81%99%E3%80%82

Also Spectrum's plan, a quick check shows the following for international travel
https://www.spectrum.com/mobile/plans/international

If you enter "Japan" in the "Calling and Data Rates by Destination" field, you will get the rates while in Japan.
Talk Talk Calling and Data Rates by Destination Talk $ 0.05 / min, Text $ 0.02 intl, Data $ 0.01 per mb.
1 GB = 1000 MB, so $ 10 / GB, which is rather expensive.

The detailed settings are probably on the Apple site above, but
Make sure your data communication is through a physical SIM purchased in Japan, and
be careful not to be charged by Spectrum for data communication through an eSIM. Please be careful not to be charged by Spectrum for data communication via eSIM.

International Caller
Thanks for the info.
I used to be a T-Mobile customer about 10 years ago, but being a cheater, I am now a SPECTRUM customer because of the price. In the future, I will check not only the price but also the service content carefully before signing a contract. Thank you very much.
