SMS Delivery Speed & Timing Table
To ensure maximum deliverability and compliance with mobile carrier standards, GenioSms uses a smart pacing algorithm. This prevents your SIM cards from being flagged for "spam-like" behavior and ensures a stable connection between our servers and your devices.
How Sending Speed is Calculated
Rather than a fixed rate, our system operates within a safety window. On average, a single device sends one SMS every 10 to 20 seconds.
While it is technically possible to send up to 6 messages per minute per device, the timings indicated in the table below represent our optimized maximum delivery times. These intervals are carefully calibrated based on extensive testing to protect the integrity of your mobile lines and comply with the terms of service of most global carriers.
Optimizing Your Throughput
If you need to deliver large volumes of messages in a short timeframe (avoiding, for example, late-night deliveries), the solution is scalability, not speed tuning.
● Multi-Device Power: To double your speed, simply connect a second device. To send 10x faster, connect 10 devices. GenioSms acts as a coordinated gateway, distributing your campaign across all active lines simultaneously.
● Carrier Diversity: For massive campaigns, we recommend using SIM cards from different mobile operators. This distributes the traffic across different network infrastructures.
● Business Plans: Whenever possible, use Professional or Business SIM plans. These are designed for higher traffic volumes and offer more stable network priority than standard consumer lines.
Estimated Delivery Time Table
The following values represent the maximum time required to complete a campaign based on the number of connected devices.
| Smartphone | sms sent in 1 hour | sms sent in 5 hours | sms sent in 10 hours |
|---|---|---|---|
| 1 | 180 | 900 | 1800 |
| 3 | 540 | 2,700 | 5,400 |
| 10 | 1,800 | 9,000 | 18,000 |
| 20 | 3,600 | 18,000 | 36,000 |
For volumes above 10,000 SMS, we strongly recommend using a minimum of 5-10 devices to ensure delivery within professional daylight hours.
Key Considerations for High-Volume Campaigns
1. The "Night Gap": Marketing messages should be delivered when users are active. If a campaign is too large for a single phone to finish by evening, adding more devices is the only way to ensure all messages arrive before the "night gap."
2. Future Updates: We constantly monitor carrier behavior. If our data shows that sending speeds can be safely increased without risking SIM blocks, we will update the gateway logic accordingly.
3. Redundancy: Using multiple phones doesn't just increase speed; it provides redundancy. If one device loses signal or runs out of battery, the others will continue the task.
