Not satisfied with this provider at all. Firstly, their network is just horrible, sometimes it’s impossible to receive calls, and my clients complain they can't reach me. I checked my sim on various devices, but the poor quality remained the same. Secondly, constant billing with mistakes. Once they invoiced me for USD 50 for just one call. I talked to the customer service who advised I should wait for the next billing period so they could correct it. Eventually, I was billed at full rate again. Are you serious?! My conclusion: keep away from this dishonest service provider!
