物理 SIM カードと eSIM の違いは？
Although eSIMs have been on the market for several years, they're considered a new technology for many people. eSIM は端末に組み込まれており、eSIM プランを購入してインストールすることで有効化できます。
物理 SIM カードでインターネットに接続するには、カードを携帯電話に挿入しなければなりません。 As for the eSIM, it's considered virtual and can be activated with the click of a button. Without the need for a physical card, you have greater flexibility in moving between eSIMs on your device.
However, eSIMs are still unavailable on all phones, so you'll have to ensure your phone supports this innovative technology. You can find a list of eSIM-compatible devices here.

旅行で eSIM を使うメリット
There's no doubt that eSIMs facilitate communication. All you have to do is get an eSIM plan from a provider like Airalo, follow the steps to install your eSIM and connect to a local network. 携帯電話を接続できるようにするために、自宅（または空港）を出る必要がありません。
目的地がどこであっても接続できるため、これは旅行者にとって eSIM が理想的な解決策である多くの理由の 1 つです。 物理 SIM カードを eSIM に交換することで、携帯電話のサイズがよりコンパクトになった可能性ももう 1 つのメリットと言えるでしょう。 eSIMs are much smaller than a physical SIM and don't need a tray, meaning they take up less space in your device.
特に旅行の際に物理 SIM ではなく eSIM を使用するのには、他にも以下のようなメリットがあります。
1. Peace of mind: With an eSIM, you don't need to switch to a physical SIM when traveling to different countries. 代わりに、新しい eSIM をリモートでダウンロードすると、即座に使用し始めることができます。
2. Flexibility: eSIM allows you to easily switch between different calling or data plans depending on the country, giving you more options to find what works best for you.
3. Lower costs: eSIM plans are usually more affordable than international roaming prices. And you won't get surprise fees.
4. More secure and no risk of losing your SIM: Because it works virtually, you don't have to worry about your eSIM being lost or stolen.
5. Keep your number: If you're traveling internationally and have an eSIM, you can keep your number and use it abroad with the same phone. 旅行中に新しい電話番号を取得する手間を省くには最善の方法でしょう。
6. Regional eSIM: Instead of changing SIM cards as you travel, you can purchase a regional or even global eSIM to cover everywhere you plan to visit.
7. Better for the environment: eSIMs eliminate the need for physical SIM cards, which are often thrown away after use and contribute to waste and pollution. また、チップはリモートで購入して更新できるため、梱包や輸送の必要性がありません。
8. Stay connected: It can be challenging to stay connected when you travel, especially if you're unfamiliar with local service providers. eSIM では旅行中のネット接続がはるかに簡単です。 目的地に到着したら、端末に従来の SIM を残したまま通信事業者を仮想的に変更することができます。
9. Save time: It's easy to activate an eSIM remotely, which means you can connect to the Internet as soon as you arrive at your destination. This is a huge time-saving feature, as you don't have to waste time searching for a local SIM card vendor.
