Using Existing Number with WhatSnap
Learn the benefits and risks of using your existing personal or business phone number with WhatSnap SMS, and why a dedicated number is recommended.
Guidance on using your existing personal or business phone number with WhatSnap SMS.
Can I use my existing number with WhatSnap SMS?
Yes, using an existing personal or business number with WhatSnap SMS is technically possible, and many users do so successfully.
However, we strongly recommend using a separate number dedicated solely to your WhatSnap SMS activities.
Why Use an Existing Number?

Why We Recommend a Dedicated Number
Risk 1: Blocking Your Primary Business Line
The Big Risk:
If anything goes wrong with your SMS campaigns (accidental mass send, spam-like content, volume spike), your number could get flagged or blocked by the carrier.
What This Means:
❌ Can't send ANY SMS (including personal/business texts)
❌ May impact voice calls (carrier-dependent)
❌ Customers can't reach you
❌ Critical communications disrupted
❌ Business operations impacted
Real-World Scenario:
You accidentally send 2,000 SMS messages at once
(forgot to enable drip mode)
↓
Carrier flags your number for spam-like behavior
↓
Number blocked within 2 hours
↓
Customers can't reach your main business line
↓
Lost business, frustrated customers
↓
Takes days to resolve with carrierCritical Risk: If your primary business number gets blocked, it can severely impact your business operations. A dedicated number contains the risk to just your CRM messaging.
Risk 2: SIM Card Blocking
When SIM Blocks Occur:
Sending high volume too quickly
Spam-like message content
High opt-out rates
Carrier fair use violations
If It's Your Personal/Business SIM:
❌ Lose access to important number
❌ May not be recoverable
❌ If blocked permanently, lose the number forever
❌ Years of business history tied to that number - gone
Recovery Difficulties:
Sometimes carrier will unblock
Sometimes they won't
No guarantees
Long-standing business numbers are at risk
With Dedicated Number:
✅ If blocked, just get new SIM ($10-30)
✅ Main business line stays safe
✅ No impact on critical communications
✅ Minimal disruption
Risk 3: Mixing Personal and Business
Challenges:
Hard to track business vs. personal messages
Business metrics get polluted
Risk of syncing personal conversations to CRM
Confusing for team members
Harder to manage DND and opt-outs
Better Separation:
Dedicated business messaging number
Clear distinction
Clean CRM data
Professional operation
When Existing Number Makes Sense
Scenario 1: Low-Volume, Conversational Use
Acceptable IF:
✅ Sending <50 messages per day
✅ Only appointment reminders and customer service
✅ NOT doing cold outreach or campaigns
✅ NOT doing database reactivations
✅ You understand and accept the risks
Why This Is Lower Risk:
Low volume = less likely to trigger carrier flags
Conversational style = doesn't look like spam
Personal responses = good engagement metrics
Important: Even low-volume use carries risk. If you ever plan to scale or run campaigns, start with dedicated number from day one.
Scenario 2: You're a Responsible Reseller or Consultant
If Setting Up for a Client:
You must explain the risks clearly to your customer:
Your Responsibility:
Educate on risks - Number could get blocked
Set expectations - Don't use for mass texting campaigns
Establish guidelines - Appointment reminders and notifications ONLY
Provide alternatives - Offer to set up dedicated number instead
Safe Use Cases for Existing Number:
✅ Appointment reminders (scheduled workflow)
✅ Notifications (order updates, service alerts)
✅ One-to-one customer service conversations
❌ NOT mass outreach campaigns
❌ NOT cold SMS
❌ NOT database reactivations
Critical:
You do not want to be the reason a client loses a business-critical phone number!
If mass texting or marketing blasts are required, set up a separate dedicated number.

Essential Precautions
1. Configure Personal Message Filtering
In WhatSnap Dashboard:
Configure settings to NOT automatically create new contacts
Only sync contacts already in your CRM
Personal messages stay in native Messages app
Business messages go to GoHighLevel
How It Works:
Messages from CRM contacts → Sync to GHL
Messages from non-CRM contacts → Stay on phone only
Prevents personal conversations from entering CRM
See: Preventing Personal Messages
2. Use the whatsnap-blacklist Tag
Tag personal contacts with
whatsnap-blacklistThese contacts' messages won't sync to GHL
Prevents mixing personal and business
3. Follow Strict Volume Limits
Never exceed 50-75 messages per day on personal number
Use proper drip mode (1 msg per 2-3 minutes minimum)
Avoid anything that looks like mass marketing
4. Monitor Closely
Check delivery rates daily
Watch for carrier warnings
Be ready to stop immediately if issues
5. Have Backup Plan
Keep backup SIM ready
Know you may need to switch numbers
Document migration process
Inform customers if number changes
