This is a scam website
This is a scam website. Please avoid using it. They charged my PayPal account after I used the trial version to send an SMS, which cost $0.56. That's fair; I was prepared to pay that. A month later, I checked PayPal and saw they were repeatedly charging $76 each. I couldn't find a way to contact their support, but I reached them by email and provided all the details. They refused my refund and were very rude. I strongly advise against trusting or using any of their services.
