    Setup in 2 minutes

    Installation guide.

    Pick your phone. Follow five steps. Be online before takeoff. We strongly recommend installing on Wi-Fi before you travel.

    01

    Open your QR email — on a different screen.

    You'll need to scan the QR with your iPhone's camera, so open the email on your laptop, tablet, or print it. The QR is in the message titled "Your gosimless eSIM is ready."

    Heads up: Each QR can only be installed once. Don't scan it on a phone you don't plan to travel with.
    02

    Connect to Wi-Fi, then open Settings.

    Activation needs internet. Hop on hotel or home Wi-Fi before starting.

    Settings→Cellular→Add eSIM
    03

    Tap "Use QR Code" and scan.

    Point your camera at the QR. It auto-detects in a second or two. If your camera struggles, tap Enter Details Manually and copy the SM-DP+ address and activation code from the email.

    04

    Label your new line.

    Name it something obvious like "Travel" or "Japan trip". iOS asks which line to use for iMessage, FaceTime, calls and data — keep your home SIM as default for everything except data. Set the new gosimless line as your Cellular Data source.

    Stay reachable: Keeping your home line active for calls/SMS means people can still reach you on your normal number — without the roaming bill.
    05

    Turn on data roaming — for the new line only.

    Go to Settings → Cellular → [Your gosimless line] → Data Roaming and toggle it on. Leave roaming off on your home SIM to avoid surprise charges. The eSIM will auto-activate when you land and connect to a local network.

    Troubleshooting

    Five things to try before emailing us.

    "QR won't scan"

    Increase your laptop's brightness, or open the email on a tablet. If your camera still can't read it, use Enter Details Manually and paste the SM-DP+ address.

    "No service after activation"

    Toggle Airplane Mode on for 10 seconds, off again. If still nothing, check that Data Roaming is on for the gosimless line. Local network registration can take 2–5 minutes after landing.

    "Slow speeds"

    Inside iPhone Settings → Cellular → Network Selection, switch from Automatic to a specific carrier (the partner networks are listed in your order email).

    "My home number stopped working"

    In Cellular settings, make sure your home SIM is set as the default voice line. The gosimless eSIM should be data-only.

    "I deleted the eSIM by mistake"

    Email [email protected] with your order number. We'll re-issue the QR if the eSIM hasn't expired.
