With hundreds of login attempts and transactions occurring at any given moment, businesses rely on an OTP SMS Service Provider to handle this complex yet integral part of their business. If you are a business and struggling with finding a great  OTP SMS Service Provider in India, here is a list of the top 6 of them.
