Xperia Z1 looses mobile data connection

[PHF]

I keep loosing the data connection 1-2 times a day sometimes more. At this point no extra symbols are displayed in the notification bar. The phone is connected to 4G, wifi on but not connected and stamina mode is turned on but battery is fully charged/connected to charger. Stop/starting mobile data, or turning wifi off does not help, only rebooting helps restoring data connection.

The phone is only 2 weeks old.

Build number is 14.2.A.0.290, Baseband 8974-AAAAANAZQ-10270025-26

Hello everyone! I ask a question: why sometimes during a phone conversation data signal disappears and 5-10 seconds after the call ends, it is the signal H +?

Most probably your signal is not powerful enough during a call and you lose connection. H+ is 3G+ (up to 21 Mbps).
