ⓘ January 2026: Impacted Oppo devices
Testing has identified that some Oppo devices may encounter issues reaching Emergency Services (i.e. ‘000’ & ‘112’) in certain circumstances. This currently affects OPPO A53s.
It is critically important that phones can reach Emergency Services.
We encourage OPPO A53s device users to urgently update the software on their device to the latest software version by 1 February 2026. Otherwise, amaysim is legally required to block these devices on 9 February 2026 to comply with mobile safety standards.
Once blocked, your device(s) won’t be able to make any calls (including to Emergency Services), texts or use data on the mobile network. You also won’t be able to call amaysim for support from your device(s).
