FAQs
Q: What do the signal bars mean?
A: Signal bars (usually 0-5) represent signal strength. More bars mean better reception and faster data speeds. Even one bar may work for calls, but data may be slow.
Q: Why is signal good but calls fail?
A: Signal bars show reception strength but don't guarantee call quality. Network congestion, carrier issues, or poor data connectivity can cause call failures despite good signal.
Q: Can metal cases affect signal?
A: Yes, metal cases can block or reduce cell signal reception. If you have signal problems, try removing your case to test if it improves reception.
