You want the most direct way to communicate with your customers, saving you time and money.
Invite your customers to receive the results of their medical examinations on a particular day and time by sending a bulk SMS. Each SMS begins with the personal salutation of the customer and includes the date to receive the test results and the cost of the examination. As a result, your staff does not need to carry telephone calls, since the customer has all the necessary information written at the SMS.
Use Web2SMS service, which is the most direct and low cost tool to communicate with your customers.
