~85% Success Rate
User reviews report that SMS-Activate has approximately an 85% SMS delivery success rate. That means roughly 1 in 7 verification attempts fail, wasting time even if the money is refunded. Quackr uses real carrier numbers for higher reliability.
Russian-Based Company
SMS-Activate is headquartered in Russia. Some users have concerns about data privacy under Russian jurisdiction, and the company may be affected by international sanctions or payment restrictions.
Complex Interface
SMS-Activate's dashboard has a steep learning curve with many options, service categories, and a bidding system ("Free Price"). For users who just need a quick verification, the interface can feel overwhelming compared to simpler alternatives.
20-Minute Activation Window
One-time activations on SMS-Activate expire after 20 minutes. If the SMS doesn't arrive in time, you need to request a new number and start over. Quackr's rental model gives you more time and flexibility.
Quackr provides real, non-VoIP phone numbers trusted by over 2 million users worldwide. Whether you need a free temporary number for a quick verification or a private number for long-term use, Quackr delivers reliability, global coverage, and flexible payment options.
