I have unlocked Samsung Note 5 and suddenly it's giving me No Sim Card error. I removed and cleaned sim card and restarted it multiple times but it doesn't help. How to resolve this issue?
Try your Sim in another T-Mobile phone and try somebody else's Sim in your note 5. If it works then you may need a new sim.
Could you try using a different sim card if you have one?
