We often hear that SMS messaging is of good help to businesses. What about the voice SMS?
First, let us get clear what voice SMS is.
In plain language, an voice SMS converts the content of a text message to a voice and sends it to people.
Therefore, people who receive a voice SMS are like picking up a phone call, only to listen to the message instead of reading it.
Why do merchants choose to send voice SMSes instead of SMS messages?
a. The message of a voice SMS is convenient to get. People can do other things while listening to it. For example, they may be walking, driving, grabbing a coffee. It would take much more effort for them if they read a text message.
b. Voice SMS is easier to track and calculate. As the sender, you may not know the exact open rate of your SMS messages or who exactly reads them. But for voice SMS, you can know exactly who picks up the phone and how long they have listened.
You will have a more detailed analysis of your voice SMS campaign.
c. With a gentle and nice voice, the voice SMS can convey emotional information to the receiver. It makes people feel closer to the sender.

Usually, people will be more impressed by voice calls. They tend to be more careful to get the message from a voice call. As people receive too many text messages each day, they may not pay much attention to the information in it, especially regards to commercial messages.
However, voice SMS also has its disadvantages.
When people are not convenient to pick up the phone, for instance, during a meeting or watching a movie, people may miss the voice SMS. Unlike text messages, people can read them silently.
What should you do? Call them again, or send an SMS message instead.
These can all be alternative solutions.

You can use voice SMS to realize the same functions as the SMS message.
1. Notifications.
No matter what industry you are in, there are many notifications you can send to your customers.
To social apps, notifications could be new friend invitations, a new message, a new system change, etc.
To game apps, you could notify the players of new level promotions, new weapons, suits on-sell, and new player invitations, etc.
To the logistics industry, the parcel status along the way is what you can notify your customers.
...
You can view voice SMS as a communicating and serving tool for your customers.
The goal of the voice SMS is to serve and build a good relationship with them.
2. Reminders.
When there is an upcoming event or a scheduled meeting, you can send voice SMS to the customers to remind them of the events.
3. Promotions.
New discounts, new promotion events, new vouchers are what you can convey to your customers.

According to the experience, the time length of a good voice SMS is around 30 seconds. Within this period, a voice message can include much information.
So, if you design a voice SMS, make sure it is around 30 seconds. Not make it too long. Otherwise, people may hang up earlier.
Do not use voice SMS for detailed information, like directions, numbers, names, instructions, and so on. These types of information are better conveyed through SMS messages.
