Anyone have any idea why my Primary Sim keeps changing automatically? I'm trying to keep my esim as primary and my work sim as the secondary. Setting for Data switch is turned off. It seems it automatically switches and makes my work Sim the Primary and I cannot figure out why.
Worst answer possible. It's obviously a phone OS issue, I have the same problem and I have to check every now and then to make it didn't change it back.
I am having this same issue. The OS keeps switching to my secondary line that doesn't have data and the phone stops working. I have to keep switching the primary SIM a few times a day now. This just started happening after the last update. No issues before that. Super annoying! Is there a fix yet?
I disagree, I have been having this problem too. It seems like this is an operating system problem, since everything I find about this issue implies that it is a user setting but the operating system keeps overriding it based on network availability. SIM services might be managed by the carrier but the phone itself is triggering the setting change.
I don't have any data on my 2nd SIM, so whenever this happens my phone stops working properly. I don't care if T-Mobile has 5G available and Verizon has no data in this location, I cannot use my T-Mobile SIM for anything but call/text so switching is not only useless but harmful for me.
Same issue here! I bought the phone directly from samsung unlocked, I am using the S24 Ultra, however. It keeps automatically switching esims on me to my secondary number with no internet.
I ended up removing esim, getting one physical sim and I'm able to forward iMessages to my android via the beeper app, and use call forwarding and virtually have eliminated the sim issues and the need to carry/worry about 2 phones all the time.
I have the same issue with both physical Sims on my S24. I have already chosen which sim for which pupose (call, data,...) so the auto-switching issue is an OS issue, cannot blame it on the network provider.
