When should I contact Simbo support?

After the steps above — especially install errors, no network after 10 minutes, or a broken QR. Send your order number.

Do I need to change APN in every country?

Usually no. If there is still no data after enabling eSIM roaming — check APN or contact support with your destination.

Simbo plans are usually data-only. Calls stay on your home line or Wi‑Fi apps.

Troubleshooting

Practical steps for common issues abroad — no internet, QR already used, APN and roaming charges. Try these before contacting support.

Install often succeeds but data does not work at your destination.

Turn on Data Roaming for the eSIM line — and off on your home line.
On iPhone: Settings → Cellular → set the eSIM line for Cellular Data.
Toggle Airplane mode for 10 seconds — this can refresh network registration.
Still no data? WhatsApp us with destination and a screenshot of cellular settings.

Sometimes the line is installed but off or not selected for data.

Check Cellular settings — if missing, retry install from email (only if not activated).
Set the eSIM line for cellular data (not voice only).
Turn the line on if disabled — on iPhone: “Turn On This Line”.
If the line vanished after an OS update — recheck compatibility and reinstall.

Most Simbo plans auto-configure APN — manual entry is occasionally needed.

Toggle Airplane mode, wait 15 seconds, try again.
On Android: Settings → Network → APN — confirm a profile exists for the eSIM.
If you received an APN in email or order details — enter manually. Otherwise contact support.

Each eSIM code is for one device — it cannot move after successful activation.

If you scanned the same QR twice — use the profile already on the device.
Changed phones — you need a new plan; an activated code cannot transfer.
Install failed without activation — contact support with order number before retrying.

Your home SIM may roam if data roaming is enabled on it.

Install needs stable Wi‑Fi and an eSIM-capable, carrier-unlocked device.

Use stable Wi‑Fi — not cellular data only.
Confirm device compatibility and carrier unlock.
Retry QR scan or manual install with the code from email.
Carrier lock error — contact your carrier; Simbo error — WhatsApp with screenshot.
