Get a VoLTE SIM - VoLTEsim

Important

A VoLTE SIM is not the same as a standard mobile or IoT data SIM. It must carry an ISIM application on the UICC and be provisioned with IMS Private and Public Identity by the operator. Putting a standard data SIM in a VoLTE device will result in data working but voice calls failing.

What type of VoLTE SIM do you need?

The right SIM depends on your device and application:

Application	SIM type needed	Key considerations
Lift emergency phone	VoLTE consumer or M2M SIM with IMS	Reliability and coverage at the site. Test in situ.
Intruder alarm dialler	VoLTE SIM – voice path or data+voice	ARC compatibility. Some ARCs accept IP; some need voice path.
Fire panel communicator	VoLTE SIM with voice entitlement	Dual-path option (IP primary, VoLTE backup) is best practice.
Telecare / PERS device	VoLTE SIM – voice and data	Network coverage at the user’s location is critical.
Cellular router with voice module	VoLTE M2M SIM with ISIM	Confirm module firmware supports IMS before ordering SIM.
Lone worker device	VoLTE SIM with roaming if mobile user	Roaming VoLTE requires inter-network IMS agreements.
