Dual SIM card problem, SIM 1 not working properly

[Saurabh3015]

Hi Team,

I have Xperia XZs from last 1 year. Recently I have inserted two sim in my phone, one is airtel and another is jio. Airtel is on 3g mode and jio is on LTE/4g mode. I have selected airtel as data network. Now my jio sim doesn't getting 4g network. For jio 4g network,  I have to select jio sim as data sim. As I select data sim my network mode automatically switchs to 4g on select sim. And restarts every time for optimization of network. Restart doesn't require even in cheaper brand then sony. I think it is not as difficult for Sony developer to fixi this restarting issue.

Can you switch SIM positions and test if you still have the same issue?

Note: When uploading a screenshot to the forum, make sure it doesn't contain any personal info (like phone numbers). The third screenshot had one so it was not approved.

Thanks for replying, I have tried sim switching also. But issue remains the same. I have tried it many times.
