If you have two SIMs on the mobile then is post is for you.

Dual SIM can be used in almost all mobile sets except for the iPhone. There are many problems with these sets of Dual SIM.
While talking in a SIM, the other SIM shows a lot of time off. There are some suggestions for solving this problem today.
We occasionally have a problem with those who use Dual SIM phones. And that is, when talking with SIM-1, SIM-2 shows off or SIM-2 shows off when SIM-2 is talking.
Although using the MCA, however, these failed calls can be seen later, but in most cases it is too late. If the calls you have received are very important then you have to face many problems.
It was supposed to be that when talking to SIM-1, showing the call waiting of SIM-2 or talking about SIM-2, the sim-1's call waiting would be shown. But it is not in your set. What do you do now Find out the matter now.

Activate your first SIM-1 and SIM-2 call waiting activate.

Now go to Settings, call Settings, go to Sim-1 Call Settings and go to Call divert. (On all phones, the call divert option may not be in Settings, then you need to find the option of Call Divert).

Now if you are unreachable or divert if out of reach, go to this other option to go to other number.

Go to Ok with the number of SIM-2.

Just go to the other number of Sim-2 Call Settings and repeat the number of SIM-1 with the same rule.

But you must be careful, while showing the call waiting of SIM-1 or SIM-2, there will be a sign of divert above that you should understand that calls of SIM-1 or SIM-2 are diverted to SIM-2 or SIM-1A Came.

However, do not receive the call during the waiting period, then the equal amount of the caller will also be deducted from your account. If you do things like this then you will not have the same problem before
