Common Questions
How much does a Japan eSIM cost?
SimSwift Japan eSIMs start at $1.99 for 1 GB valid for 7 Days. Unlimited daily plans start at $1.99 a day.
When does the Japan eSIM activate?
It activates when you connect to a supported network in Japan (usually upon arrival). No manual activation needed—just land, turn on your phone, and you're connected, whether you're exploring Tokyo, Kyoto, or Osaka.
How does an eSIM work?
An eSIM is a digital SIM built into your phone that activates mobile data without a physical card. After purchase, you install the Japan eSIM in one tap from your order email. Once you arrive in Japan, your phone connects to local networks automatically—no SIM swaps or roaming fees.
How do I install Japan eSIM on iPhone?
Open your order email on your iPhone and tap the install button: the eSIM installs in one tap, then follow the prompts. Once installed, select the eSIM as your data line. You’ll need to enable Data Roaming on the eSIM line (not your primary SIM) to connect in Japan.
How do I install Japan eSIM on Android?
Open your order email on your Samsung, Pixel or other eSIM phone and tap the install button: the eSIM installs in one tap. Set the eSIM as your data line and enable Data Roaming on the eSIM profile to use mobile data in Japan.
Can I install my Japan eSIM before travel?
Yes! Install anytime before your trip—it won't activate until you arrive in Japan and connect to a local network. You have 180 days from purchase to activate.
Do I need to turn on Data Roaming for Japan eSIM?
Yes, enable Data Roaming on the eSIM line (not your primary SIM). This allows the eSIM to connect to local networks in Japan. You won't be charged roaming fees—it connects as a local plan with no extra charges from your home carrier.
Does Japan eSIM support hotspot/tethering?
Yes, you can share your data with other devices using hotspot on most plans. Many travelers do this while visiting Osaka's Dotonbori shopping streets or relaxing at beaches in Okinawa.
Will WhatsApp work with a data-only eSIM?
Yes! WhatsApp and iMessage stay linked to your home number. The Japan eSIM is data-only, so your existing messaging apps work perfectly—you keep all your chats and contacts.
Can I make calls with a data-only eSIM?
This eSIM doesn't include a phone number for regular calls/SMS. However, you can make calls using WhatsApp, FaceTime, Skype, or other internet-based apps over your data connection.
How long is Japan eSIM valid after purchase?
You have 180 days from purchase to activate your Japan eSIM. Once activated, the plan validity depends on the package you chose (shown on the product page).
Can I top up my Japan eSIM?
Yes! All fixed data plans support instant top-ups. Purchase a top-up package using your original eSIM reference number—there is nothing to reinstall.
Which networks does Japan eSIM use?
Your eSIM connects to premium local networks including KDDI with 3G/4G/5G coverage. Whether you're in Tokyo, Kyoto, or Sapporo, you'll get the same quality service with automatic switching for the best signal.
Is Japan eSIM better than buying a local SIM?
Yes—no airport queues, passport checks, or language barriers. Install your Japan eSIM before you travel, land at iconic spots like Mount Fuji or during your Kyoto temple visit, and connect instantly. Local SIMs require finding a store, dealing with paperwork, and physical swapping.
