Iphone 12 Pro Max in dual sim
Hy there,
Seems that when I use a hard SIM and an e-SIM for 2 different carriers the signal drops below the one SIM usage signal.
Is anyone of you have the same problem?
Thanks!

Perhaps your iPhone is locked to a specific carrier.
See this paragraph:
To use two different carriers, your iPhone must be unlocked. Otherwise, both plans must be from the same carrier. If a CDMA carrier provides your first SIM, your second SIM won't support CDMA. Contact your carrier for more information. If you have an enterprise or corporate cellular service plan, check with your company administrator to see if they support this feature.
