Hi asunni2009,
Please try deactivating and activating the SIM.
Does the problem appear on other SIM cards?
Please tell us your operator name and country.
Could you tell us your current firmware version? Settings > System > About phone > Build number
Could you show us a screenshot of the problem?
Thank you 🙂
