The best part of using spark is that it gives you all your communication needs without any hassle, as I have been able to reach my clients from anywhere in the world with ease. It's also easy for me because whenever there are issues or problems they can be rectified within minutes compared to other providers who take hours before even acknowledging them. There isn't much about this service provider which makes one dislike but if anyone has used different types of platforms like WhatsApp then he/she will know how good their customer support team performs when things go wrong sometimes. If you're looking forward to having an app where everything runs smoothly than just give it a try! We use sparks mainly for video calls to our customers so we don't need many features such as file sharing etc. Their customer care department helps us solve almost every problem quickly and efficiently. This saves time for both parties involved. They offer free trial periods too unlike others who charge heavily at first sight.
