COMPATIBILITY
Check the hardware
before the plan.
eSIM phones and portable hotspots fail for different reasons. Record the exact model and identifiers, then match a plan that ecosystem can actually activate.
PHONES
eSIM-ready and unlocked
Look for an eSIM or add-plan setting. Confirm the device is not carrier-locked. A model that supports eSIM in one country version may not in another.
Travel eSIMHOTSPOTS
Model plus ecosystem
Write the manufacturer, model, and device ID, serial, or IMEI. Cloud-bound devices usually cannot take a random SIM or phone eSIM.
Portable Wi-FiWHAT TO SEND US
Identifiers that actually help.
- Brand and exact model string from the label or Settings.
- Whether the phone is unlocked.
- Hotspot device ID, serial number, or IMEI if you have it.
- Destination countries and travel dates.
HI9 does not certify every device on the market. We help you check the right identifiers and avoid plans that the hardware cannot use.
