My iPhone Signal Loss Issue with DITO SIM

I am experiencing frequent signal loss on my iPhone when using a DITO SIM. The issue persists regardless of location, causing interruptions in calls, texts, and mobile data. I have tried basic troubleshooting steps like resetting network settings, toggling airplane mode, and reinserting the SIM, but the problem remains unresolved. My device is updated to the latest iOS version and works fine with other carriers. Is this a compatibility issue between DITO and iPhone, or could there be other factors affecting the signal?
