What it means for IoT devices in Thailand
- 2G still runs on some networks, but plan new devices on 4G-based technologies (LTE Cat-1bis, LTE-M or NB-IoT where available): 2G is being closed across the region.
- Private delivery works the same from Thailand: device data reaches your cloud over private links. See private delivery.
