Work through these steps in order — most issues fix within the first few:
Restart your phone — power off completely (not just lock screen), wait 10 seconds, power back on. Wait a minute for the signal to return.
Toggle Airplane Mode — turn it ON, wait 10 seconds, then OFF. Wait a minute.
Check your subscription is active — open the Zable app and go to the Zable Mobile section.
"Payment Failed" or "Suspended": update your payment method in Settings. Service reactivates within 5–15 minutes
"Cancelled": resubscribe in the app
Check your eSIM settings:
iPhone: Settings > Mobile Data > Zable — line ON, Mobile Data ON, Data Roaming ON
Android: Settings > Network & Internet > SIMs > Zable — SIM Enabled, Mobile Data ON, Roaming ON
Remove and reinstall your eSIM — you'll need your original installation QR code. If you don't have it, email support for a new one before doing this step.
- iPhone: Settings > Mobile Data > Zable > Delete eSIM, then reinstall
- Android: Settings > Network & Internet > SIMs > Zable > Remove, then reinstall
Reset network settings — last resort only. This will erase saved WiFi passwords, Bluetooth pairings and VPN settings.
- iPhone: Settings > General > Transfer or Reset iPhone > Reset > Reset Network Setting
- Android: Settings > System > Reset Options > Reset Wi-Fi, mobile & Bluetooth
