IPhone 7 no service recall

Troubleshooting iPhone 7 no service:

1.

Please check -> iPhone 7 Repair Program for "No Service" Issues

2. 

If it doesn't help, remove and reinsert the SIM card.

If it doesn't help visit your carrier, maybe the SIM card is damaged, ask for a replaced (new) card. Normally it is free.

Ask also to check if the SIM tray is bent, as even a tiny misalignment can cause the SIM card to not fully connect with the internal contacts in your iPhone.
