WhatsApp on Dual SIM iPhone
Greetings,,,, I activated a second permanent att SIM on my iPhone 13 Pro Max. Now I have two separate phone numbers. One number was already registered with my personal WA Messenger, and I wanted to register the new second phone number with WA Business. When I install Business app, it first defaults my personal phone number, but it gives me the option to use a different number. I enter the new number, but it fails to either sending SMS activation code or call. Both SIMs are fully functional receiving SMS, Calls and internet connection is up. I did reset network settings, reinstalling the app, and all other possible online troubleshooting tips. Thx
iPhone 13 Pro Max, iOS 17
