Activation failed: IPhone activation requires an update

Hello, my problem is:

After the update on ios 13.2, I lost the network, I put the phone in recovery mode, as a result, all data were erased, when trying to activate IPhone is given this error: "Activation failed: IPhone activation requires an update," the network phone still does not catch, simcard in it - no, where the network is usually shown writes "No network," simcard is not inserted.

How do I solve this problem?
