<p class="lead mb-3">Heading to Japan and not sure if your phone supports eSIM — or how to actually set one up? This guide walks you through every step: checking compatibility, choosing a plan, installing the eSIM before departure, and activating it the moment you land.</p>
  <p class="mb-3">The whole process takes under five minutes. No airport queues, no SIM card swaps.</p>

        <p class="mb-4">An eSIM is a "digital SIM card" built directly into your smartphone. By simply downloading a data profile, you can access cellular networks just like you would with a physical SIM card.</p>

This allows you to receive important calls or texts on your primary number while enjoying affordable local data. Plus, there's zero risk of losing your original SIM card.</p>

    <p>Open your phone's dialer and type <strong>*#06#</strong>. If an "EID" number appears on screen, your device supports eSIM. No EID means you'll need a physical SIM card instead.</p>

    <h3 class="fw-semibold mt-4 mb-2" style="font-size:1.05rem;">How to check if your iPhone is carrier-unlocked</h3>
    <p>Go to <strong>Settings → General → About → Carrier Lock</strong>. If it says <strong>"No SIM restrictions,"</strong> you're ready to install a Japanese eSIM.</p>
    <p>If your iPhone shows a carrier restriction, contact your carrier to request an unlock before you travel. iPhones purchased directly from Apple or sold as unlocked are already SIM-free.</p>
    <p>On Android, check under <strong>Settings → Connections → SIM card manager</strong> (wording varies by manufacturer). When in doubt, contact the carrier you purchased the phone from.</p>

      <strong>Do you need to enable Data Roaming?</strong><br>
      No. CDJapan eSIM connects directly to Japan's docomo network, so Data Roaming does not need to be on. This is different from roaming-type eSIMs (Airalo, Ubigi, etc.), which require Data Roaming to be enabled.

<h3 class="fw-semibold mb-2" style="font-size:1.05rem;">Using your eSIM as a hotspot</h3>
    <p>CDJapan eSIM supports hotspot sharing out of the box — no extra settings needed. If hotspot isn't working, try setting the APN manually. See the <a href="https://prepaidsim.cdjapan.co.jp/eSIM/article/52">hotspot sharing guide</a> for details.</p>

    <h2 class="section-title">eSIM Not Working? Quick Checklist</h2>
    <p>If you're connected but not getting data, run through this list first:</p>
    <ul>
      <li>Is your phone <strong>carrier-unlocked</strong>? (Check Step 1 above.)</li>
      <li>Is Data Roaming <strong>off</strong>? (For CDJapan eSIM, it should stay off.)</li>
      <li>Try toggling <strong>Airplane Mode</strong> on, then off — this resets the network connection.</li>
      <li>Restart your phone.</li>
      <li>Confirm the eSIM is actually <strong>activated</strong> in your Cellular settings (not just installed).</li>

    <h2 class="section-title">Why Choose a Japan-Local eSIM Over a Global Provider?</h2>
    <p>Not all Japan eSIMs work the same way. There are two fundamentally different types, and understanding the difference will save you a lot of frustration.</p>

<h3 class="fw-semibold mt-4 mb-2" style="font-size:1.05rem;">Roaming-type eSIM: how it actually works</h3>
    <p>Most global eSIM services — Airalo, Holafly, Saily, and others — use roaming technology. When you open Google Maps or send a message in Japan, your data doesn't connect directly to a Japanese network. Instead, it routes through overseas servers, typically in China or Singapore, before coming back to Japan.</p>
    <p>The practical result: even when the signal looks strong, pages load slightly slower, Google Maps takes a beat longer to respond, and streaming video buffers more than it should. You may also find that certain Japan-only services and apps don't work, because your connection appears to originate from outside the country. On top of that, roaming-type eSIMs require you to enable <strong>Data Roaming</strong> in your phone settings — which can sometimes trigger unexpected charges if your home carrier's roaming kicks in instead.</p>

<h3 class="fw-semibold mt-4 mb-2" style="font-size:1.05rem;">Local-type eSIM (CDJapan Rental): direct connection to Japan</h3>
    <div class="info-box-blue mb-3">
      <span class="badge-docomo">docomo direct</span><br>
      CDJapan eSIM connects directly to Japan's docomo network — the country's largest carrier, with over 99% national coverage. There's no overseas detour. Your data goes straight from your phone to Japan's infrastructure and back.
    </div>
    <p>The practical result: low latency, full speed, and a genuine Japanese IP address. Japan-only apps and streaming services work exactly as they do for local residents. You also never need to enable Data Roaming — in fact, for CDJapan eSIM, Data Roaming should stay <strong>off</strong>.</p>
    <p>If you're traveling for business, or you simply want a connection that just works without configuration headaches, a local-type eSIM is the right choice.</p>

    <div class="faq-item">
      <h3>Does the QR code expire?</h3>
      <p class="mb-0">The QR code itself has no expiry date. Your plan's countdown only begins when you activate the eSIM in Japan — not when you scan the QR code.</p>
    </div>
    <div class="faq-item">
      <h3>Can I transfer my CDJapan eSIM to another device?</h3>
      <p class="mb-0">No. Once installed, a CDJapan eSIM is tied to that specific device and cannot be moved or reinstalled on a different phone. If you need a new device, you'll need to purchase a new plan. Note that this is a CDJapan Rental policy — other providers may handle this differently.</p>
    </div>
    <div class="faq-item">
      <h3>I accidentally deleted my eSIM — can I reinstall it?</h3>
      <p class="mb-0">Unfortunately, deleted CDJapan eSIMs cannot be reinstalled. Before deleting an eSIM, always contact support first. See our guide: <a href="https://prepaidsim.cdjapan.co.jp/eSIM/article/79">Accidentally Deleted eSIM in Japan? Can It Be Reinstalled?</a></p>
    </div>
    <div class="faq-item">
      <h3>What if I activate the eSIM before arriving in Japan?</h3>
      <p class="mb-0">Your plan's days start counting from the moment you activate it. Activating before departure means you'll lose those days before you even land. We recommend installing (scanning the QR code) at home, but waiting to activate until after you arrive in Japan.</p>
    </div>
    <div class="faq-item">
      <h3>Does CDJapan eSIM support voice calls or SMS?</h3>
      <p class="mb-0">CDJapan travel eSIMs are data-only plans. Voice calls and SMS are not supported. For calls, use apps like WhatsApp, LINE, or FaceTime over your data connection. See our guide on <a href="https://prepaidsim.cdjapan.co.jp/eSIM/article/44">using WhatsApp in Japan</a> for more.</p>

        <p>世界中で使えるAiralo、Holafly、Sailyが取り扱っているeSIMは「ローミング」通信で日本の通信キャリアに接続します。Redditなどで遅延の問題や一部サービスが使えないと報告されているのは、技術的な要因が大きいです。</p>
        <p>一方、日本企業が提供するeSIMは、日本の大手キャリアのネットワークに直接つながる<strong>「日本国内直結型（ネイティブ型）」</strong>です。ローミングタイプと違い遅延もなく、日本国内でのサービスに制限を受けることはありません。あなたの日本滞在の快適さを決定づけます。</p>
