Today, almost every smartphone model you’ll come across features the dual-sim feature. Two sims allow you to use one number for personal use and the other for corporate use. What if your one number loses connectivity while you’re awaiting an important call on that number?

In such tricky situations, I recommend diverting or forwarding your calls to the second number when the other sim is unreachable. But how to do it? Read on as I discuss how to divert someone’s calls to your phone number and much more.
So, let’s get right into this.
What Is Call Forwarding Or Diverting?
In layman’s terms, call forwarding or diverting, as the name suggests, is an interesting feature that allows users to divert or forward calls to another phone number on the same or another device. It was invented by Ernest J. Bonanno.
There are several reasons that prompt users to turn on the call forwarding option on their device. For example, if one of your sims is notorious for network problems, you can set up call forwarding on that number.
Doing so, all your calls on that particular number will get diverted to the other sim (or any other number you wish). Similarly, call forwarding offers you several other benefits.
Different Types Of Call Forwarding
Now that you’re well-versed with what is call forwarding, let’s now move to the different types or services under it. These include:
Always forward
As the name speaks for itself, selecting always forward on any number will forward all its calls to another number you’d set till you decide on otherwise.
Call forward when busy
Select the service call forward when busy if you’re awaiting an important call while speaking to someone else at the moment. This way, you’ll neither miss your important call nor would need to cut the current call in between.
Call forward when unanswered
Are you in a meeting or occupied with something important that’s not allowing you to answer any call? If you find yourself in such a crunch situation, I recommend setting up the call forward when unanswered service. This way, all your unanswered calls will be forwarded to another number of your choice.
Call forwarding when unreachable
Are you like me who doesn’t like missing out on any calls? If yes, you’d try the call forwarding when unreachable option. When enabled, the calls will be forwarded to an alternate phone number if your phone is out of the network coverage area or unreachable for other reasons.
So, these are the four main services or options under the call forwarding umbrella.
How To Divert Someone’s Calls To Your Phone Number?
Besides diverting your calls to another phone number, you can also divert someone’s calls to your phone number, provided you’ve access to their device. If you do, here are the two quick methods.
Call settings
To set your phone number as the forwarding destination of someone’s calls, you’d have access to their handset for a few seconds as said earlier. Once their device is in your hands, go to the main Settings, open the Call settings, and head to the Call-forwarding settings.

Based on the device you’re on, you’ll be asked to enter the number the incoming calls should forward to. Enter your phone number in the required field and save the settings.
Now, all the incoming calls on that person’s number will be forwarded to you.
Number code
Another quick way to get others’ calls diverted to your phone number is by using predefined number codes that vary with network providers. However, most network providers use **21*<10-digits mobile number># as the call forwarding code.
In other words:
- **21* forwards all incoming calls
- **61* forwards all unanswered calls
- **67* forwards calls when the line is busy
- **62* forwards calls if the phone is unreachable
To deactivate call forwarding, simply replace the * in the above codes with the #.
In other words:
- ##21# will deactivate all forwarded calls
- ##61# will deactivate all unanswered calls
- ##67# will deactivate all calls when the line is busy
- ##62# will deactivate if the phone is unreachable
So, that’s how to divert someone’s calls to your phone number.
Note: If you’re at the receiving end here and your calls are being forwarded to another number, you can confirm the same by using the *#21# code. It’ll return with the list of people your texts or calls are being forwarded to.
You can further undo this call diversion by dialing ##002#.
Does The Caller Know That The Call Is Being Forwarded?
The simple answer to the above question is YES. The caller will get to know if their call is being forwarded since they’ll directly connect to the forwarding destination.
It depends on the telecom providers how they let the caller know about the above. For example, some telecom providers play a message that their call is being forwarded to another number.
In some cases, the slight delay while setting up the call is also a clear indication of a call being forwarded.
With more advanced features making their way to your handset, there can be a little change in the ring or delay before ringing to indicate that the call forwarding feature is in action.
