確かに、海外での通信って心配になるわよね。でも、安心して！SIMカードやeSIMを使えば、現地でインターネットを使えるのよ
Yeah, using the internet abroad can be a concern. But don’t worry! You can use either a SIM card or an eSIM to stay connected while you travel.

1. SIMカードとeSIMの違いDifference between SIM Card and eSIM
SIMカードって、現地で購入して、スマホのSIMカードを差し替えれば、現地の4Gとか5Gのモバイルデータ通信を使うことができるってこと？
So if I buy a SIM card at my destination and swap it into my phone, I can use local 4G or 5G mobile data, right?

そうよ。インターネットが必要なときに、わざわざ空港やカフェのWi-Fiスポットを探して、ログインする面倒もないから、海外旅行で現地のSIMを買う人が増えてきてるわ
Exactly. You won’t need to hunt for Wi-Fi spots at airports or cafes, so more people are choosing to buy local SIMs during international travel.

現地の空港って、Wi-Fi飛んでてもすぐにログインできなかったり、空港の外に出たらネットに繋げられなくなるし、大体空港で買えるんだよね
Even at airports, sometimes Wi-Fi doesn’t connect easily, and once you leave, you lose access. But you can usually buy a SIM at the airport, right?

そうよ。でも言葉が通じなかったり、割高のプランを押し付けられたり、気をつけないとね。キキちゃんは英語が堪能だから、そのへんは大丈夫かな？
True, but sometimes you might not speak the local language or might get pressured into an expensive plan, so you have to be careful. But you’re great with English, so you should be fine, Kiki!

うん。だけど、ネットがないと、現地の相場やちょうどいいプランとかもわかんないし、騙しのプロたちがウヨウヨしてるから、いつも無駄にお金を使っちゃうんだ
Yeah, but without internet, it’s hard to know the right price or plan, and there are plenty of scammers around, so I always end up spending too much.

そうよね。なかには、空港って特に意味不明に割高だし、悪質な業者や詐欺も多いから気をつけないとね
Exactly. Airports are often unnecessarily expensive, and there are many scammers and bad agents, so you need to be careful.

キキちゃん、せっかくの海外旅行の時間をSIMカードをゲットするのに30分くらい費やすのは絶対イヤだ
And honestly, Kiki-chan really doesn’t want to waste 30 minutes of my trip just to get a SIM card.

さすがキキちゃん、世界を駆け回る国際人ね。
You’re truly a globetrotter, Kiki-chan!
SIMカードの差し替えも面倒くさいし、お店の人に挿し替えてもらうのにスマホを渡すのも不安だし
Swapping the SIM card is also troublesome, and handing my phone to someone in the shop to change it makes me a bit uneasy.

走って逃げられちゃったら大変よね。実際、そういう人もいたわ。あとは、日本に帰ったときに、日本のSIMカードなくしちゃってたら最悪だよね
Yeah, it’d be awful if they ran off with your phone. It’s happened before. Plus, imagine returning to Japan and realizing you’ve lost your Japanese SIM card. That’d be the worst!

だから、もっとサクッとネットに繋げられるといいよね。飛行機が着陸したらすぐにネットに繋ぎたいし、お友だちにすぐに「着いたよ」って伝えたいし
Exactly! So there should be a faster, easier way to get online! I want to be online as soon as my plane lands. I also want to message my friends right away saying “Arrived!”

Time, information, and communication are essential. In that case, Kiki, eSIM is the way to go instead of a SIM card!
