WordPress developer and online entrepreneur Internet Small-Business (50 or fewer emp.) 2/24/2026 "Affordable, Lightning-Fast SMS Delivery with Top-Notch Support" 5/5 What do you like best about GatewayAPI? Their services are affordable, SMS messages are delivered to the recipient incredibly quickly, and the support is top-notch! Review collected by and hosted on G2.com. What do you dislike about GatewayAPI? They're very thorough with onboarding new customers, which makes the process a bit longer. However, they follow European regulations, so that's the way it is. Their terms and conditions stipulate a €2 fee if you don't send any messages for 60 days. You can fix this by sending one message manually each month. Review collected by and hosted on G2.com. Recommendations to others considering GatewayAPI: Due to the intensive onboarding process, you can't start using their services right away. Create your account during their office hours, and you'll always have someone available to chat with you. Review collected by and hosted on G2.com. What problems is GatewayAPI solving and how is that benefiting you? For the web applications I build, I need a properly functioning API for sending SMS messages. GatewayAPI has such an API, and this allows me to easily integrate their service into my applications. Review collected by and hosted on G2.com.

OL Oleg L. 1/7/2026 "Reliable SMS Deliveries with Exceptional Support" 5/5 What do you like best about GatewayAPI? I find GatewayAPI very effective for sending SMS messages to our customers based on their purchases. GatewayAPI allows us to easily track if the SMS is delivered or not, which is enough for our needs. The most important factor is that servers are in EU and and that pricing is good for us. The most significant aspect is their excellent customer support, which has been fast, reliable, and always helpful. Review collected by and hosted on G2.com. What do you dislike about GatewayAPI? I don't like that EU service isn't the default for EU customers. When I receive an email, it sometimes directs me to the US version, and I have to switch manually. EU companies, like mine, prefer the EU version by default, and this is becoming increasingly important. Review collected by and hosted on G2.com. What problems is GatewayAPI solving and how is that benefiting you? I use GatewayAPI to easily send SMS messages to customers based on purchases, and it allows tracking delivery status. The service is straightforward and reliable for our needs. Review collected by and hosted on G2.com.
