What To Choose Between Voice APIs And SMS APIs For Your Mobile App

When building a successful mobile application, you pay attention to many things including its usability, design, and, of course, functionality. In fact, the set of features available to users might be one of the keys to creating an outstanding product. And, while providing the service that is important to your customers is essential, having an excellent communication is a crucial part of this process.

SMS & voice APIs are a must-have in a modern mobile app. If you are wondering what they are and which one is better for your business, this article is going to be your guide to choose SMS & voice APIs in order to help you make up your mind. Besides, we are going to provide you with key information about the biggest players in this market as well as compare some of their main features.

Why You Should Consider Integrating VOIP & SMS APIs In A Mobile Application

The main advantage of SMS and voice APIs is that they allow you to communicate any updates or changes to your audience instantly. This makes the process easier for everyone involved. Of course, an application can do without these features but it can be a beneficial addition to your product. Before we dive into the comparison of available voice & SMS APIs, we need to be on the same page regarding their usage. Below you can check descriptions of the main features and why they can be valuable for enhancing your business.

  • User verification

Many applications include verifying a user account using the phone number during the signup or password reset. So, the SMS and VOIP APIs can help perform this verification in an efficient manner.

  • In-app communication

The internal communication performed within the application is a great way of providing excellent service. This makes it possible to connect providers with the customers and vice versa. With the voice and SMS APIs integration, this communication process can be carried out with no delay.

  • Push notifications

Keeping customers up-to-date during the whole length of their experience with your application is a great practice. Push notifications can be triggered by some changes within the account, the order status update or any other actions. In order to send these notifications, integrating SMS APIs in your iOS app is necessary.

  • Number masking

This feature can be a great deal in keeping your customers’ information safe if they need to contact the service provider and they are not willing to disclose certain information about themselves. This interaction from inside the app can be made possible by integrating VOIP APIs.

  • Bulk messages

At times, some information will need to be communicated to the customers. That’s when broadcasting messages comes in handy. These notifications may be about some important changes you are about to implement, or have just implemented, any discounts, ToS changes. Basically, anything that has to be shared with a large group of people falls into this category. Such announcements require an SMS API to be integrated.

The differences between SMS APIs and voice APIs should be taken into account to see which one is a better fit for your business. These descriptions should provide you with an idea of why you may need voice and/or SMS APIs for your application. But the question how to choose one still remains. Let’s see what you need to know to make your choice.

What Matters When Choosing An API For Your Application

Here are a few things you would like to look at first when choosing SMS & voice APIs for your on-demand mobile app.

  • Pricing. The most expensive solution does not always mean it is the best one. If a cheaper option has everything you require, do not hesitate to use it.

  • Reliability. Don’t hesitate to check the reviews or give it a test drive (if possible) to see how reliable the system is.

  • Geographical availability. This point might limit you in your choice as some of the APIs simply might not have coverage in your country.

  • Delivery reports. It’s not an obligatory option but it will definitely give you some great pieces of information for analysis.

  • Integration. Last but not the least point to consider is how easily can you integrate VOIP & text SMS in a mobile application.
