OTP verification by sms

I want to use OTP by SMS in my app…
I want it for SMS (because I want the OTP through of SMS).
But how should I do that?
I tried to do it…
And I made an app regarding OTP.
It was working when I put other phone’s no. into the phone no. field…
When I put the phone’s phone no. in it, It didn’t work.
How do I settle it?
Please have a look at my code blocks…
