Help/Troubleshooting
Is my phone compatible?
You need an eSIM-capable, unlocked phone—check your device settings or manufacturer list before buying.
Short answer
PuffinFi eSIMs work on phones that support eSIM and are unlocked (not locked to a single carrier). Most recent iPhone and many Android flagship models qualify—confirm on your device before you buy.
Steps
- iPhone: Settings → General → About — look for an available EID, or try Cellular → Add eSIM.
- Android: Settings → Network & internet → SIMs — look for download/add eSIM. Presence of an EID in About phone is a good sign.
- Confirm the phone is unlocked with your current carrier if you recently financed or subsidized it.
- If you cannot add an eSIM at all, the device likely cannot use PuffinFi.
Tips
- Tablets and laptops with eSIM can work when the OS supports adding a data eSIM the same way.
- Dual-SIM devices can usually keep your home number and add PuffinFi for data.
Escalation
If you purchased a plan and cannot add an eSIM because of device or lock restrictions, email support@puffinfi.com with your order reference and phone model.
