Great service for SMS activations. In 90% of cases, everything goes smoothly, and the remaining 10% are either used or "dead" numbers, delivery issues, or errors on the part of the services themselves. Sometimes, SMS doesn't arrive on certain platforms for some countries. I usually choose Kazakh or European/American numbers; I used to take our local ones, but they have been removed now. After purchasing, you can copy the number in your personal account and use it for registration. If everything is fine, the SMS arrives within 10-15 seconds. If it takes longer, there’s probably a problem. In such cases, I usually wait another 5-10 minutes and contact support. They usually accommodate and replace the number. The prices of the service are reasonable. I've seen cheaper options, but the quality of the numbers is worse there, and issues with registrations occur more frequently. There’s no particular sense in choosing more expensive options; the quality here is quite acceptable.
