Dual SIM error

[rjwill10]

Hi,

I have an S23 Ultra. I have two SIM cards in the phone. Both work, but in SIM manager, only one is recognised. I keep getting an error for the second SIM, but it works perfectly fine.

I've tried restarting the phone and reinterting the SIM. Keep getting the same error. Has anyone else experienced this?

If you swap the sims around does the same error occur? If yes replace the sim

Swapping the SIMs around worked. I switched them back again and got the same error. How strange.

Check your SIM is activated with your network provider sometimes when you add an esim it has to be activated by your mobile before it will work.

Thanks, but it's a physical SIM. The second SIM works, but keep getting the error when trying to add it to the SIM manager.

It may be an issue with the SIM card, try giving it a clean or request a new SIM card as it might not be connecting properly. If nothing else it can rule out a faulty SIM. Other than that I could only suggest getting your phone checked if you can rule out an issue with SIM and network.

I have the exact same problem with mine. can't figure it out..

Is there a fix? I have the same with mine but both Sims say failed but both seem to be working! Strange!

New galaxy s23 yesterday put 2 physical SIMs in one unrecognised but both worked. Later in the day SIM 2 recognised and I turned it off as no at work. Today it says no SIM in slot 2 and I cannot get it to work, turning off, etc. Swapping SIM cards around the one I slot 1 works and the other saying no SIM. IE both SIMs work in slot 1 neither in slot 2. Any suggestions. Thus is the second S23 I've had this issue with

Hello, I am having this exact issue. 2 physical sims, both worked fine in the beginning, but after a while got an error on sim 2. I switch the SIM cards around, the card in slot 1 always works and the card in slot 2 never works. Does anyone have a fix for this?
