Factors That Affect Reliability
While WhatSnap's infrastructure is highly reliable, these factors can impact your specific setup:
1. Device Connectivity (Your Control)
High Impact:
⚠️ Unstable WiFi/mobile data → Messages delayed or queued
⚠️ Device powered off → No messages sent until device back online
⚠️ Battery optimization killing app → Gateway disconnects
Solutions:
Use stable WiFi or reliable mobile data
Keep device plugged in 24/7
Disable battery optimization for WhatSnap Gateway app
Monitor device status in WhatSnap dashboard
See: Device Configuration Best Practices
2. Carrier Network (Carrier Control)
Moderate Impact:
⚠️ Carrier outages → Temporary delivery failures (rare)
⚠️ Poor signal strength → SMS delays
⚠️ Fair use policy violations → Account restrictions
Solutions:
Choose reliable carriers (see SIM Plan Recommendations)
Ensure strong signal where device is located
Follow carrier fair use policies
Have backup SIM from different carrier
3. Android Device (Your Control)
Low-Moderate Impact:
⚠️ Low-end devices → Occasional app crashes
⚠️ Aggressive power management → App killed in background
⚠️ Software updates → Temporary restarts
Solutions:
Use recommended devices (4 GB RAM+)
Configure proper power management settings
Schedule updates during off-hours
Monitor device health regularly
Reliability Features Built Into WhatSnap
1. Message Queuing
How It Works:
Messages that can't be sent immediately are queued
Queue holds messages until device reconnects
Automatic retry when connection restored
Example:
Device loses WiFi at 2:00 PM
5 messages attempted during outage
Device reconnects at 2:30 PM
All 5 messages automatically sent within minutes
2. Connection Monitoring
Real-Time Status:
WhatSnap dashboard shows device status (Online/Offline)
Mobile push notifications when device disconnects
Email alerts for extended downtime (optional)
Proactive Alerts:
Know immediately if device goes offline
Address issues before customers notice
Track device uptime history
3. Delivery Confirmation
Message Tracking:
Real-time delivery status for every message
"Sent", "Delivered", "Failed" indicators
Failed message notifications (optional)
Benefits:
Know if messages aren't delivering
Quickly troubleshoot issues
Maintain high quality standards
4. Multi-Device Redundancy
Scale & Backup:
Connect multiple Android devices
Distribute load across devices
If one device fails, others continue working
Setup:
Configure multiple SIMs in WhatSnap dashboard
Use workflows to distribute contacts
Monitor each device independently
See: Multiple SMS Accounts Guide

Backup Strategy
Recommended Redundancy:
Primary device: Main SIM, handles bulk of messages
Backup device: Second SIM, standby or handles overflow
Different carrier: Reduces single-point-of-failure risk
Implementation:
Configure both devices in WhatSnap dashboard
Use workflows to split load 70/30 or 50/50
If primary fails, manually shift all traffic to backup
Or: Use backup only during primary maintenance
Troubleshooting Reliability Issues
Device Frequently Disconnects
Common Causes:
Unstable WiFi
Battery optimization killing app
Low device memory
Manufacturer restrictions (Xiaomi, Huawei)
Solutions: See Troubleshooting Guide
Messages Delayed or Queued
Common Causes:
Device offline temporarily
Carrier network congestion
High volume exceeding carrier limits
Solutions:
Check device connection
Reduce sending rate
Add more devices for distribution
Low Delivery Rate (<95%)
Common Causes:
Spam-like content
Sending too fast
Carrier flagging account
Invalid phone numbers
Solutions: See Database Reactivations - Avoiding Blocks
