Hi all,
I'm deploying an nRF9160-based device in India and hitting the familiar "which SIM actually works here" wall. Looking for current (2026) experiences, since older threads are out of date and the operator landscape keeps shifting.
What I've tried:
- Airtel M2M NB-IoT SIM — provisioned fine, but NB-IoT coverage at my location( Bangalore ) was poor and unreliable. Device couldn't get a stable attach.
Where I'm stuck — questions:
1. For anyone running nRF9160 in India in 2025–2026: which operator's NB-IoT are you actually getting a reliable attach and data on? Jio keeps coming up as the main NB-IoT operator — can anyone confirm current nRF9160 experience?
2. Jio NB-IoT is reportedly Non-IP (data tunneled via their server rather than standard IP sockets). For those using it — how are you handling this on the nRF9160 side? NIDD, or is there an IP APN available now?
3. Has anyone sourced a small-quantity NB-IoT SIM (R&D, under 10 SIMs) without the 100-SIM enterprise minimum?
Any band-lock (%XBANDLOCK) or APN config that made the difference would be a huge help.
Thanks!
