Whatsapp SMS Authentication now became easy with the latest change. Whatsapp tweaked its SMS authentication system while setting up the account on the new phone. This tweak helps us in the following scenario.
Imagine that you two phones. One is 1234 and the second one is 5678. Consider that your primary number is 1234, but you are willing to use Whatsapp on 5678 number phone.
So in this case, if you are setting up Whatsup on 5678 phone with 1234 as the primary number, when you entered 1234 as your Whatsapp account number the account verification SMS will be delivered to the first phone and the 5678 phone right now you are using fails to auto verify the code. Alternatively, you have to wait for 3 Mins time to verify through a phone call.
The latest Whatsapp verification tweak stripes away the whole problem. Irrelevant of what number you are using right now on your phone, Whatsapp provides “verification code box” immediately along with auto verify mechanism. So just you need to enter the verification you got on your primary phone instead of waiting for Phone call verification.
This tweak will be more helpful for those who are using dual-SIM phones and maintaining two separate phones.
