To verify whatapp in a DUAL SIM mobile

Earlier there use to be only single SIM phone.
But when the technology has improved,DUAL SIM phones came in to existence.

Now in this post, am going to explain how whatsapp works on a DUAL SIM phone.

Now just follow this procedure…

But before this you need to have the two SIM cards inserted in your phone.
Now for the explanation, I considered SIM1 as permanent number and SIM2 as temporary number.
If I want to register my SIM1 with whatsapp application,then

1. Launch the application in your phone
2. Enter SIM1 number and tap on “OK” button.
3. Verification process will completed in 10-15 secs of 10 minutes total time.
4. Your phone will get registerd with its own SIM1(mobile) number.

Suppose if i want to change my number to SIM2,then

1. Launch the application in your phone.
2. Tap on change phone number option in settings.
3. Enter the “old phone number(SIM1)” and “new phone number(SIM2)” in respective fields and tap on next button.
4. Again the verification process will continues.
5. Again after 5 minutes,your phone (SIM1) will receive a message from Whatsapp server which contains 6 digits code.
6. After the total time(10 minutes),Displays a popup showing “SMS verification has failed,continue voice verification by calling the entered number”.
7. After tapping on “call me” button,again a popup appears with “Enter code here” field.
8. As soon as we tap on “call me” button, a call from Whatsapp server will come to the entered number.
9. This call will continue till we attend the call.
10. If the call was answered,a 6 digit number will be heard by voice.
11. If we enter the 6 digits code which was heard,your phone will get registered with the entered number and call gets automatically disconnected.
12. Otherwise if we enter the 6 digits code which was received as an SMS,then also your phone will get registered with the entered number. i,e. Device A SIM1(mobile) number.

But the SIM2 gets unregistered.
As whatsapp will work only in one device with one sim.
Here it considered the second scenario as one device with dual sim i.e,different IMEI numbers will be present for DUAL sim mobiles.
At first it considered SIM1 but when try to change to SIM2,then verification process continued.
