What is meant by a Bulk SMS Service Provider?

When the title or phrase comes up with the terminology of a bulk SMS service provider it is referring to a service a specialized IT company is able to distribute a large volume of short text messages (SMS) directly to mobile phones. It is a great way of sending out an alert, a reminder, a form of advertising or some form of an update to employees and customers promptly in just a few words. The main users of such communication are usually media companies, banks, consumer branded organisations, and entertainment companies. But it is widely used by small and medium sized enterprises whether they are dentists, physiotherapy or doctors as reminders or alerts as a means of communications.

Software used by Bulk SMS Service Providers

From a client perspective there is virtually no software required other than access to the internet (i.e. web- based) so that the client can tell the Bulk Service provider what message needs to be disseminated promptly. From the bulk sms provider aspect, it will have developed a variety of reliable software packages for sending and receiving bulk SMS  These software packages have the ability to provide users with the ability to add as many mobile phone numbers as needed and in a way that they can be managed by different ways. Most SMS software applications have the structure in place to upload lists and groups of mobile numbers using either a text file or as a CSV file system.

Dependent on the nature of the bulk SMS service provider, many of the bulk service provider’s software applications are sophisticated enough to be able to automatically add or delete any duplication numbers as well as to be able to validate prior to sending the text message.  Most bulk SMS Providers have the standard application program interface called API to allow program designers to add text messaging service to programs such as FTP, SMPP, HTTP and Email.

With such features, SMS can be scheduled to any desired time, day or month and be distributed through a national and international telecommunication network as long as they have such facilities.

In all the cases that were reviewed, there was a security policy that meant that each provider took security very seriously.

Customer Care Support by bulk SMS service providers

This was an interesting area to review. There were bulk SMS companies that either did not provide any customer care contact numbers like MessageBird or provided an international call centre number but with the time difference, this could be a real issue. Only two providers, namely ClickSend and SMS Solutions had a telephone number that was accessible on a 24/7 basis. The other bulk sms providers had a  number, some not expressing the time it would take to respond. Some companies had Live Chat and some offered a free trial on the basis of a specific number of SMS for the trial to no offer or a minimal charge or a time period to trial their service.

All bulk SMS providers did have an email contact but some stated it could take a day or two to respond and all provided real time reporting availability. Some of the providers are overseas based while others are UK based such as ClickSend, SMS Global, BurstSMS and SMS Solutions UK.

ClickSend and SMS Solutions were ranked as the best in terms of customer care support service.
