Hello,I need an SMS gateway like Twilio. I am testing it right now, but before investing in a commercial product I would like to map the better alternatives.Plivio was recommended for me, but Plivio PHP based configuration more difficult to integrate. Do you know any good International alternative to Twilio?In addition to the basic functionalities, it would be appreciated if the SMS gateway offers affordable price range and 24/7 system support would be also useful for me.Thank you for sharing your ideas in advance!
