When ever I change my data service from jio to airtel, the jio sim got switched off. If I try to keep jio in lte mode the data connection changes from airtel to jio. Kindly develop a solution to keep jio sim open even if data is used via other sim
i am facing same problem after security update but samsung didn't solve yet this problem. i had cintacted them 2 times but didn't replied regarding this actual problem.
Thank you for reaching out to the Samsung community! We would like to inform you that it is the default feature of the device. In Samsung device at a same time only one SIM slot will connect to the 4G/LTE network. The device SIM will connect to the internet having highest network mode configuration (3G/LTE/Auto mode). So, whenever user changes the data mode from one SIM to another the other SIM will automatically change the network mode to 2G. As JIO SIM only support 4G/LTE network the JIO SIM will not work if you want to use data in other SIM slot.
