Unreliable delivery and unresponsive support
I used EasySendSms to send verification codes to German mobile numbers, and unfortunately I cannot recommend the service. The main problem: a large proportion of the SMS messages never reached the recipients — yet the very same messages were shown as "DELIVERED" in the backend. This discrepancy between the reported status and the actual delivery makes the service unusable for any serious purpose. For verification codes in particular, where reliable delivery is essential, this is a dealbreaker. I requested a refund as a result. To this day I have neither received the money back nor had any response from customer service. My messages simply go unanswered. Bottom line: unreliable delivery, misleading delivery reports, and a support team you can't reach. I would advise against using this service.
