Should I Use a Dedicated Phone or Client's Phone?
The Decision
This is entirely up to you. WhatSnap users have found success with both approaches:
Option 1: Agency Keeps Dedicated Phone
Purchase dedicated device for WhatSnap
Manage setup and maintenance yourself
Completely separate number for business messaging
Option 2: Client Provides/Uses Their Phone
Use client's existing phone
Client keeps their existing number
Less equipment investment
Agency Keeps the Phone
✅ Advantages
Complete Control
Full control over device setup and configuration
Always On
Ensure phone is always powered and connected
Easy Troubleshooting
Direct access for any technical issues
No Client Dependency
Not affected if client turns off phone or loses signal
Professional Setup
Optimize device specifically for WhatSnap
❌ Disadvantages
No Call Reception
Client cannot receive phone calls through the device
Equipment Cost
Agency must purchase device and SIM plan
Ongoing Management
Agency responsible for all device management
Client Keeps the Phone
✅ Advantages
Easy Setup
Use existing device, no new equipment needed
Client's Existing Number
Keep established phone number
Call Reception
Messages and calls go directly to client
Lower Cost
No new device purchase required
❌ Disadvantages
No Control
Agency has no control if phone is off or out of range
Difficult Troubleshooting
Harder to fix issues with non-technical clients
Signal Dependency
Messaging stops if client loses signal or powers off
Client Dependency
Success depends on client keeping phone on and connected
When to Use Dedicated Phone vs. Client's Phone
Use Dedicated Phone (Agency Keeps) if:
✅ Running database reactivation campaigns (high volume)
✅ Implementing chatbot automation with constant back-and-forth messaging
✅ Need guaranteed 24/7 uptime
✅ Managing multiple clients from one setup
✅ Client is non-technical or unavailable for support
Use Client's Phone (Client Keeps) if:
✅ Low to moderate messaging volume
✅ Client wants to keep their existing number
✅ Client needs to receive calls on the same number
✅ Client is technically capable
✅ Budget constraints prevent new device purchase
Critical Warning: We do NOT recommend using a client's existing phone if you are doing:
Database Reactivation campaigns (high volume)
Chatbot automation with constant SMS activity
Any scenario with risk of SIM blocking
In these cases, always use a separate dedicated number to ensure there is no possibility of compromising a client's existing SIM card.
Remote Management Options
Managing Client's Phone Remotely
If the client keeps their phone, you can still troubleshoot remotely:
Remote Access Tools:
AnyDesk (free for personal use)
TeamViewer (free for personal use)
Zoho Assist (used by many agencies)
See: Remote Access Guide for setup instructions.
Benefits:
✅ Troubleshoot without physical access
✅ Configure settings remotely
✅ Train client on setup
✅ Verify connection status
