Addressing the challenge of non-deterministic SIM selection for mobile data in your Ubuntu-based system, especially when managing calls and SMS with ofono for your home automation and alarm system, necessitates a multifaceted approach. Firstly, ensuring that your ofono installation and the WIKO Riff 3 Plus phones' firmware are up to date is crucial, as updates may enhance SIM management capabilities. Since ofono's primary focus is on voice and SMS services, with less emphasis on data connectivity, you might need to delve into its configuration or leverage its DBus API for explicit SIM selection. This could involve custom scripting to enforce a specific SIM for data connectivity, tailored to your requirements. Alternatively, exploring other software solutions more attuned to dual-SIM management might be necessary, although it could mean significant adjustments to your current setup. Moreover, engaging with online communities or forums related to ofono, Ubuntu, or your specific hardware might unearth valuable insights or solutions from individuals who have encountered and resolved similar issues. This composite strategy aims to bring predictability to your SIM selection process,for example to choose a prefix number to get good data service https://whatnetworkphl.com/0955-what-network-philippines-is-tm-or-globe-sim-or-smart/ enhancing the reliability of your home automation and alarm system's communication capabilities.
