A: Yakovski thank you for the question. Unfortunately, I don’t text into Bulgaria so I don’t have an honest answer for you. I would do what I’m about to recommend for you, Google, which of those gateways would be best. Twilio seems to provide great quality service worldwide so I would encourage you to do a Google search about their rates in your country. I’m so sorry if that’s not helpful my friend, but I’d rather be honest with you than do a Google search and pretend like I’m an expert in your country.
