1. “No Service” after landing

Almost always a settings issue, not a network issue. Walk through:

1. Make sure the SimKit eSIM is enabled: iPhone Settings → Mobile Data → SimKit eSIM → “Turn on this line” should be ON. Android Settings → SIMs → SimKit eSIM → toggle ON.
2. Set the SimKit eSIM as your data line. (Calls and SMS can stay on your home SIM.)
3. Turn airplane mode on for 10 seconds, then off. This forces a network re-register.
4. If still nothing: restart the phone fully.

That sequence resolves 9 out of 10 cases.

2. “Could not activate eSIM” when scanning the QR

This is usually one of three things:

• You’re not on Wi-Fi. The eSIM download needs internet. Connect to Wi-Fi and retry.
• The QR has already been used. Each QR can only be installed once. If your eSIM is already in your phone, you don’t need to scan again — just enable it in Settings.
• You scanned with the camera app, not Add eSIM. Go to Settings → Mobile Data → Add eSIM → Use QR Code, and scan from there.

3. I deleted the eSIM by accident

Reinstall it using the same QR code from your order confirmation email. Each QR has a limited number of installs — if you’ve hit the limit, message us and we’ll re-issue a fresh QR.

4. My home SIM stopped working / I can’t receive 2FA texts

This happens when the SimKit eSIM gets set as your default voice/SMS line, not just data. Fix:

• iPhone: Settings → Mobile Data → Default Voice Line → set back to your home SIM.
• Android: Settings → SIMs → “Calls” and “SMS” should both be set to your home SIM. “Mobile data” stays on SimKit.

5. Data was working, now it isn’t

Three quick checks:

1. Have you used up your plan? Check your remaining data at your account. If it’s at zero, top up.
2. Has the plan expired? Plans run for a fixed number of days from first connection — once they’re up, the data stops.
3. Are you in a covered country? If you’ve crossed a border on a single-country plan, you’ll need a different plan or a regional/Global eSIM.
