I have been using this service for a year, but not just this one – I usually compare several similar platforms to find better deals. Currently, the reliability of all services is about the same. As for SMS Fast, I can highlight the following advantages: 1. A convenient and intuitive website interface 2. A wide selection of countries and services, which allows for various price options 3. Quick crediting of money to the balance 4. The number appears in the personal account immediately after purchase 5. SMS usually arrives quickly 6. Polite and reasonable support. Disadvantages: 1. The absence of some countries and services. This is a common issue for many, so if you need Russian numbers – it's better to look elsewhere 2. Sometimes there are non-working numbers, especially for popular services 3. In rare cases, SMS may not arrive. But thanks to good support, the money is refunded, and there is an option to replace the number. Overall, the problems are typical for most similar services, so I use this one alongside others. I go for the cheaper option.
