I'm experiencing issue with Dual Sim. I'm based in the UAE and using two SIM cards on my Samsung S25 Ultra. The first SIM works perfectly, but the second one shows network coverage yet doesn't function properly. If I don't check it frequently, important SMS messages sometimes arrive a day late. To receive SMS or OTPs, I have to switch to airplane mode and back, which is really frustrating.
I previously used the S21 and never had this problem. Now I'm wondering why I upgraded to the S25,
Is there any known solution to fix this issue?
