Cell phone when temporarily returning to Japan

When I returned to Japan 2 years ago, I bought a Japanese sim card that I could use all the time, and I used it in my American iPhone
Then I bought a new American iPhone, but the times have changed and you can't put a sim card in it anymore.
I'm going back to Japan in May, so I'm doing a lot of research and I'm getting confused about E sim cards 😅

In Japan, I put my American iPhone in Airplane mode and use it in the U.S. In Japan, I plan to use my iPhone in Airplane mode and use Wi-Fi. And I wonder if it is possible to use the LINE app on my old iPhone with the account I use in the US. Two years ago, I just switched to a Japanese sim card on my American iPhone and LINE was connected normally.

If anyone knows the best way to use two iPhones in this environment, please let me know.
Please do.

Sim Card ＆ E I don't know much about Simi cards, but in our case, we have three iPhones （ that we usually use in the US. I use LINE installed on my iPhones ） when I go back to Japan by connecting to free public Wifi or Wifi at the hotel or other places where I stay. Also, when my kids went to Japan last year with some friends, they rented a pocket Wifi at the airport （ for about 300 yen per day ？ ） and used it when they needed to connect to it during their stay. Unfortunately, I can't give you advice on that since it was a long time ago when I tried to swap Sim cards like Phone did, but I hope others can give you some good advice.

I think E sim is the easiest.　If you are not confident about setting it up yourself, there are counters at the airport where you can have it installed.

＞ #2 Mr. Snotty
Thank you for your prompt advice ！ Holafly is something I've been hearing more and more about lately, so I was just curious

Thanks for your kind share! Thank you very much for your kind share. I used to use my phone in the same way without any problem, but when I came back to Japan 2 years ago, I bought a Japanese Sim card with a Japanese phone number on it, so I would like to use it if possible.
I'm not sure if the same account can be used on two iPhones, even if the iPhone is set to Airplane mode and the LINE app is used in the U.S. The world has become too convenient for my brain to keep up.

Thank you for your reply ！
If things get complicated, I'd like to use E sim, but I don't want to waste the E sim for Japan that I already purchased.

I have the same account on my ipad, and I am also using the same account on my Galaxy tablet. However, when I logged on to my Galaxy tablet the other day with the account I use on my iPhone, the line on my iPhone stopped connecting to my account on my iPhone, saying that it had been transferred to another device and was no longer available. After deleting the line on my galaxy, I can use it again on my i phone, but my past talk history is gone. I can set up a backup of my talk history in the settings of the line, so I set up a backup just in case.

Thank you very much for the very useful information ！ I think I have read somewhere that the same Apple ID is good ？ ！ I think I have read such information too. I think I read such information somewhere. I had been unable to imagine using the same LINE account on two iPhones due to various information, but now I see the light ！ ！
Thank you very much.
