How to prevent iPhone 16 Plus from losing network signal?

The iPhone 16 Plus experiences intermittent connectivity issues, with both SIM cards randomly losing service. At times, the phone displays "No Service" without any apparent reason, cutting off network access entirely. This disruption can occur sporadically, affecting both cellular networks simultaneously. After a few moments, the service reconnects on its own, but the issue repeats itself unpredictably, leaving the user without a stable signal for short periods. The phone fluctuates between service and no service, making it unreliable for calls, messages, and data usage.

If the carrier is unable to resolve your issue, take the phone in to a Genius Bar or Apple Authorized service provider. There could be a hardware problem with the phone. It is still in warranty so they should be able to help you.

Hello!

Reach out to your carrier for assistance with this. That would be your best bet.

Have a great day!

I see. Well, there not much more we can do from here in this community. I suggest you continue working with Apple and your Carrier; there must be a reason for this behaviour.

I have been having the same issue. Troubleshooted for over 2 months until finally received replacement. Replacement is having the same problem. I am thinking the 16s are defective.
