Confidence is high when the operator or the regulator states the date, medium when several independent sources agree, low otherwise. We recheck every month.
What it means for IoT devices on VinaPhone
- 2G devices no longer connect to VinaPhone. Trackers, alarms and meters that only speak GSM/GPRS need a 4G-based replacement, or a SIM that roams onto another network in Vietnam still running 2G.
- 3G works until the shutdown (September 2028). Devices that rely on 3G should move to 4G before then.
- For new devices, choose 4G-based technologies: LTE Cat-1 bis, LTE-M or NB-IoT where the network offers them.
- Foreign SIMs in Vietnam: we have not yet found a reliable source on permanent roaming. Details on the Vietnam page.
An M2M.global IoT SIM is not tied to a single network in a country, and its data can reach your cloud without the internet through private delivery.
