A friend of mine needs to send around 4000 sms every week and he asked me to find some solution to avoid his current provider (which is just a reseller) and get directly to the main providers. My first choice was nexmo, but according to him, there are solutions that give better prices, more exactly less than one cent per SMS. Maybe he is wrong or maybe Im using the wrong search terms, but I cant find any provider offering less than a cent per sms. Our requirements are reliability, preferrably USA based provider or one that accepts PayPal and including Cuba in the coverage with the desired price. Any suggestion?
