I purchased my Samsung A35 in February 2025, and it was working perfectly until the most recent software update. Since the update, I’ve been facing serious issues with my SIM cards (dual SIM setup).
When using SIM 1, I can only make and receive calls. Mobile data and SMS are not working.
When I insert SIM 2, SIM 1 stops working completely, showing “No service,” and under Settings → Connections → Mobile Networks, all options are greyed out and cannot be changed.
I have already:
Tested both SIM cards in other phones — they work fine.
Tested other SIMs in my phone — they work fine.
Performed a factory reset and used Smart Switch for software recovery.
Visited a Samsung service center, where they updated the software again — but the issue persists.
I found online that several other A35 users are also facing the network connection and SIM related issues after the recent update. It seems this could be a software bug introduced in the latest patch.
Please confirm whether Samsung is aware of this issue and when a fix can be expected. Many users including myself have already missed important calls and messages due to this problem.
