eSIM Installation Guide
Install in 3 minutes, auto-activate on arrival
One-tap install with the Yoho app
Download the Yoho Mobile app and sign in with this account — your eSIM appears ready to install, no QR scanning or copy-pasting.
Or install it manually below
Before you install
A few seconds of prep saves frustration.
Stay on Wi-Fi
Install with a stable connection so the profile downloads cleanly.
Don't interrupt
Activation can take a minute. Don't close the screen mid-install.
Give it a label
A unique name helps you spot this eSIM among other SIMs.
Choose for data
After install, set this eSIM as the line your phone uses for data.
Install your eSIM
Pick QR or Manual — you only need one.
Your eSIM QR code lives in your account
When you place an order, your scannable QR code and activation details are added to your eSIM detail page. Use that page during install — not this generic guide.
Open Settings → Cellular → Add eSIM
On the iPhone where you want this eSIM, choose Use QR Code.
Scan the QR code above
Hold the phone steady until iOS picks it up. Tap Continue when prompted.
Wait for activation
Activation may take a minute. Don't exit the screen — iOS will say Done when ready.
Label your new eSIM
Pick a name like "Yoho — Japan" so you can tell it apart later.
Pick a default line
Select Primary as your default line for calls, FaceTime, and iMessage.
Use this eSIM for Cellular Data
Choose your new eSIM under Cellular Data, then tap Done.
Connect to the network
Once installed, finish these to start using data.
Make sure the eSIM is on
Settings → Cellular → your new eSIM → Turn On This Line.
Select the eSIM for data
Settings → Cellular → Cellular Data → choose your new eSIM.
Pick for calls and texts
Settings → Cellular → Default Voice Line → choose your new eSIM.
Turn on Data Roaming
Settings → Cellular → your new eSIM → enable Data Roaming.
Troubleshooting
No internet after install?
- Check Data Roaming: Make sure Data Roaming is enabled for the Yoho eSIM line
- Check preferred data line: Make sure Yoho eSIM is set as the preferred line for Mobile Data
- Restart the phone: A restart after install resolves most connection issues
- Pick a carrier manually: If auto-connect fails, try selecting a local carrier manually
- iPhone: Settings › Cellular › Yoho line › Network Selection › turn off "Automatic" › pick an available carrier
- Android: Settings › Connections › Mobile networks › Network operators › Select manually
QR scan keeps failing?
- Make sure the QR code image is clear and complete
- Adjust distance and angle, try again in good lighting
- If it keeps failing, switch to manual entry
- Each QR code can only be installed once — if you've already installed it, don't scan again
Can I move the eSIM to a new phone?
- Most eSIMs cannot be transferred across devices. If you switched phones, contact support to reissue the activation code
- Some plans support reinstalling via the Yoho Mobile app
