Call forwarding is an advanced feature designed to assist users in seamless communication. If you have multiple SIMs and phones but prefer not to carry them all due to inconvenience, use the call forwarding feature on iPhone to direct all calls to a single phone. Simply carry the phone with the SIM configured for call forwarding. Calls to the iPhone with call forwarding enabled will be redirected to the SIM you're carrying.
How to Forward Calls on iPhone:
Step 1: To forward calls on iPhone, tap on Settings, then select Phone
Step 2: Here, under My Number, you can immediately see the phone number currently in use on your iPhone. Pay attention to the Call Forwarding feature. Tap on it and swipe right to Enable call forwarding on iPhone.
Step 3: In the Forward to interface, simply enter the phone number you want to forward calls to on iPhone. Remember to include the country code, if it's Vietnam then enter +84 to successfully forward calls on iPhone. After entering the phone number, press Back to return. At this point, you will see an additional call forwarding icon next to the network and WiFi icons on your phone.
By successfully completing the above steps, you have successfully forwarded calls on iPhone. The phone number you entered in the Forward to section will receive all calls to the SIM on your iPhone, iPad. You can forward calls on iPhone from multiple phones to one phone you use most often. If you are using a Samsung S6 or S6 Edge, you can refer to how to forward calls on Samsung S6 here.
What's even more interesting is that on the recent iOS 11 operating system, Apple also supports users with the automatic answer feature on iPhone. The automatic answer feature on iPhone will help you receive all calls, avoiding missed calls. Of course, the automatic answer feature on iPhone with iOS 11 also has its drawbacks. That is, for unknown numbers, numbers you don't want to answer, you will still automatically answer calls on iPhone because you have set the automatic call answering time. Consider carefully before setting this feature on your iPhone, iPad.
