Regarding AT QLTS command

Hi I’m using EG25 LTE module and working with this module for the last 4-5 months and my issue is when I tried with at command i.e, AT+QLTS=2 this is will synchronize the time with local but its works with only VOLTE(jio) sim but when I tried with another(SIM) one its failed to synchronization. Kindly let me know why this causing? this is from INDIA

Hi Girish,

Time is synchronized from NITZ message from network. You could check whether network registration is successful when using other SIM.
Also when you change the SIM card, please make sure APN is set correctly.

Best Regards,

Thank you WillieYao for your response
