EG25 miniPCI module RI in EMC test

We are using EG25G miniPCIe module on our IoT gateway. We were undergoing a Radiated Susceptibility test with a 3V/m signal. We saw some frequent disconnections during the test. The module recovered every time but still it disconnected multiple time at multiple frequencies. We used a GSM simulator to test this.
Is it an acceptable behaviour from the module? Or is there any configuration that we were not doing right?

Lab has suggested that it is falling under performance criteria for transient phenomena. Please confirm if that is the case.
