Forwarding calls from your AT&T mobile number to your BusinessLine number is indeed possible, provided the BusinessLine number is a US number. Here's how you can do it:
Check with AT&T:
Since methods for call forwarding may vary slightly among providers, it's advisable to reach out to AT&T customer support directly. They can furnish you with specific instructions tailored to your current plan and device. Typically, call forwarding entails dialing a particular code sequence followed by the destination number (your BusinessLine number in this case).
Verify your BusinessLine number:
Ensure that your BusinessLine number is activated and ready to receive calls. You can verify this within the BusinessLine app itself.
Additional Tips:
Call forwarding may result in additional charges from AT&T depending on your plan. Refer to their website or contact them for further details.
If you frequently require call forwarding, explore alternative solutions within the BusinessLine app, such as setting up call forwarding directly through the app's features.
