Yes, switching carriers might fix the "SOS" issue if it's caused by problems specific to your current carrier, such as poor network coverage in your area, frequent service outages, or compatibility issues with your iPhone. Before switching:
1. Check Coverage Maps: Ensure the new carrier has better coverage in your location. 2. Test with a New SIM Card: Borrow or purchase a SIM card from the potential carrier to see if it resolves the issue. 3. Confirm iPhone Compatibility: Verify your iPhone supports the new carrier’s network bands (especially for unlocked devices).
