Verifying users through SMS helps build a reliable and secure user base. The increasing appearance of bots or viruses to damage and / or steal accounts has made it necessary to increase the security of information provided by users.
Some famous apps like Whatsapp, Facebook or Instagram have already used this technology for some time. Now to further improve security you can use Google Authenticator, but for a startup with SMS is enough for now.
SMS can be used for initial registration or for continued access to a software or application in chief executive officer email list. In this case I will focus on the initial registration and the mobile market.
Having fake users or bots is frustrating and can distort the evaluation of the use of an app or even the results of some marketing campaigns. With the SMS verification we get a secure and higher quality user base.
What is the verification of new users through SMS?
The verification of new users through SMS, known as two-step verification (2FA), consists of adding an extra security field to the registration process (user, password and now SMS).
The codes sent are for single use (OTP), which means a significant increase in security in the verification process.
In this way we have an extra layer of security that confirms safely and quickly that it is real users, not bots. It is not an infallible system, but it significantly reduces the fraudulent registration rate. Verification by SMS marketing
How does it work?
The operation is simple. Today we are always accompanied by our smartphone, so we always have it on hand to perform any type of SMS verification.
Once we have chosen the platform that will offer this service we must ask our developers and technicians to perform the implementation of the service.
The user follows the steps of the registration and when it reaches a certain point, the verification code is sent to the telephone number entered.
After a few seconds you receive the code. It depends on the terminal and the technology used, the code is added automatically or you have to copy it from the SMS and add it in the corresponding field of the app.
Once this is done, the registration will have been verified with our telephone.

The potential of SMS Marketing
I would say that SMS Marketing is the most powerful tool in terms of results. According to data from Instasent (2017), on average, 98% of SMS sent in a campaign reach their recipients and 19% click on the CTA.
SMS is fast, direct, secure, little crowded and does not require internet access. If we have a decent database and we carry out good campaigns, we will obtain exceptional results at a low cost.
This is one of the reasons why we need to have real and verified users.
Companies verifying users by SMS
There are several companies that offer the service of user verification through SMS, both in new registers and in daily access to an app.
Instasent offers SMS Verify, an easy-to-implement verification service that costs € 0.045 for sending SMS in Spain.
Menssage Bird is also easy to implement. It has a bidirectional service with the user that can be interesting. The price for SMS in Spain is € 0.04. If we send messages to countries such as the US or Canada, we will need a virtual number.
Google also offers this option with Firebase (technical documentation). If we already work with Google tools, the implementation will be simple. It is free up to 10,000 SMS sent.
