Can I use a foreign IoT SIM in India permanently?

No. TRAI prohibits permanent roaming for foreign-issued IoT SIMs. Any foreign SIM must be converted to a locally registered Indian IMSI within 6 months. Multi-IMSI eSIM with a pre-loaded Indian operator profile (Airtel or Jio) is the standard solution —the Indian IMSI activates on deployment and the foreign IMSI is disabled after 6 months.

Jio or Airtel —which is better for NB-IoT in India?

Jio currently has the more reliable NB-IoT network, confirmed working across 7-8 states with standard IP mode (not limited to NIDD). Airtel dominates enterprise M2M (54% market share) and is stronger for LTE-M and 4G M2M deployments with SLA support. For pure NB-IoT sensor deployments, test with Jio first. For enterprise-grade M2M with private APN, Airtel Business is the safer choice.

Do I need to register as an M2MSP to deploy IoT devices in India?

If you are providing connectivity services (not just hardware), yes —M2M Service Provider registration with the DoT is mandatory. If you are deploying devices that connect through an Indian carrier's SIM, the carrier or your M2MSP partner handles the registration. If you are manufacturing export-only devices, the new Dec 2025 framework provides a lighter authorization path (Rs 5,000, 10-year validity).

74 millones de conexiones M2M. Airtel controla el 54%. TRAI exige conversion a IMSI local en 6 meses. Jio lidera NB-IoT en 7-8 estados; Airtel domina M2M empresarial.

74 millones de conexiones M2M. Un operador controla el 54%. TRAI exige conversion a IMSI local en 6 meses. Jio lidera NB-IoT en 7-8 estados pero Airtel domina el M2M empresarial. Estas son las matematicas de despliegue para India — no la hoja de especificaciones, la realidad.

TRAI y DoT: El Stack Regulatorio

Las directrices de registro M2MSP exigen que cualquier entidad que provea servicios de conectividad M2M/IoT en India se registre ante el DoT. Deben usarse recursos de numeracion emitidos en India. Las instrucciones eSIM de junio 2025 liberalizaron el marco eSIM. El marco de diciembre 2025 permite SIMs extranjeras en dispositivos solo para exportacion.

Jio NB-IoT vs Airtel M2M: La Decision del Operador

Jio opera la red NB-IoT mas confiable de India, verificada en 7-8 estados. Airtel domina el mercado M2M empresarial (54% de participacion) y ofrece conectividad IoT con SLA. Para sensores NB-IoT de baja potencia: pruebe Jio primero. Para M2M empresarial con SLA: Airtel Business.
