Is This Really Unlimited SMS?

Understand what "unlimited SMS" means with WhatSnap, including fair use policies, volume limitations, and best practices for maximizing your messaging capacity.

How Can WhatSnap Offer "Unlimited" SMS?

Short Answer: WhatSnap itself places no limits on the number of messages you send through our platform. You are only limited by:

  1. Your carrier's fair use policy for your SIM plan

  2. Country regulations on SMS messaging

  3. Android phone limitations (technical and carrier-imposed)

  4. Your messaging channel (SMS, iMessage, or WhatsApp)

WhatSnap's Position: We don't charge per-message and don't impose artificial caps. Your only limitations come from external factors like carrier policies and device capabilities.


Understanding "Unlimited"

What WhatSnap Doesn't Limit

WhatSnap Platform:

  • No per-message fees

  • No monthly message caps

  • No throttling based on volume

  • No additional charges for high usage

  • Flat pricing regardless of message count

You pay only for:

  • Your SIM card plan (~$10-30/month)

  • Your Android device (one-time hardware cost)

  • Your WhatSnap subscription

What DOES Limit You

1. Carrier Fair Use Policies

Every mobile carrier has a "fair use" or "acceptable use" policy for SMS:

Typical Carrier Limits:

  • Stated as "unlimited" but with fair use clauses

  • Usually tolerate 100-250 messages/day on consumer plans

  • Business plans may support higher volumes

  • Exceeding limits can result in warnings or account suspension

Examples:

  • Verizon Business: Users report 1,000+ messages with no issues

  • Lycamobile: Users report 5,000+ messages/day successfully

  • TracFone: Users report 50,000+ msgs/month across multiple devices

  • Tello: Stated 10,000/month but blocks common at lower volumes

  • Speed Talk Mobile: Maximum 2,500 SMS/month explicitly stated

See: SIM Plan Recommendations by Country

2. Country Regulations

Some countries impose legal limits on SMS:

Example:

  • France: Legal limit on SMS per month through a SIM card

  • Exceeding = potential carrier block or legal issues

Your Responsibility:

  • Research local SMS regulations

  • Comply with telecom laws in your country

  • Follow carrier-specific policies

3. Android Phone Limitations

Built-in Rate Limiting:

  • Android has protection against "SMS abuse"

  • Triggers warning if you exceed 30 SMS in 30 minutes

  • You can override, but it signals you're pushing limits

How It Works:

Sending > 30 messages in 30 minutes
→ Android warning: "App is sending large number of SMS"
→ Tap "Allow" to continue
→ Messages queued until you approve

Recommendation:

  • Stay at or below 1 message per minute sustained

  • Avoid triggering Android's built-in warnings

  • Use multiple devices/SIMs for higher volume

Realistic Volume Expectations

Conservative (Safe for All Carriers)

Single Device/SIM:

  • Week 1 (Warm-up): 10-20 messages/day

  • Week 2 (Ramp up): 50-100 messages/day

  • Week 3+ (Sustained): 100-150 messages/day

  • Rate: 1 message every 1-2 minutes

Risk Level:Low - Works with nearly all carriers

Moderate (Most Carriers)

Single Device/SIM:

  • Week 1: 20-40 messages/day

  • Week 2: 75-150 messages/day

  • Week 3+: 150-250 messages/day

  • Rate: 1 message per minute

Risk Level: ⚠️ Moderate - Works with most good carriers, may push limits on budget carriers

Aggressive (Premium Carriers Only)

Single Device/SIM:

  • Week 1: 50+ messages/day

  • Week 2: 150-250 messages/day

  • Week 3+: 250-500+ messages/day

  • Rate: Burst capable (with proper spread throughout day)

Risk Level: 🛑 High - Only achievable with premium business plans (Verizon Business, Lycamobile, etc.). Not recommended for most users.

Best Use Case

DBR & Conversational

Conversational & Low DBR

DBR & Conversational

Key Insights:

  • SMS: Best for database reactivation (DBR) and general business messaging

  • iMessage: Best for conversational messaging, limited daily reach

  • WhatsApp: Global reach, good for international, varies by usage patterns

Understanding "Unlimited" by Channel

SMS (Android):

  • "Unlimited" = Carrier fair use limit (typically 100-250/day)

  • Can scale with multiple SIMs

  • Fixed monthly cost regardless of actual usage

iMessage:

  • "Unlimited" = Apple's daily unique contact limit (~50/day)

  • After 50 unique contacts/day, may face temporary restrictions

  • Good for ongoing conversations, limited for cold outreach

WhatsApp:

  • "Unlimited" = WhatsApp's terms of service

  • No hard daily cap stated, but patterns matter

  • Spam-like behavior results in account bans

  • Business accounts have different rules than personal


Scaling Beyond Single-SIM Limits

Using Multiple SIMs

Each additional SIM adds capacity:

SIMs
Conservative
Moderate
Aggressive

1 SIM

100/day

150/day

250/day

3 SIMs

300/day

450/day

750/day

5 SIMs

500/day

750/day

1,250/day

10 SIMs

1,000/day

1,500/day

2,500/day

Benefits of Multi-SIM:

  • ✅ Distribute load across carriers

  • ✅ Redundancy (if one blocked, others continue)

  • ✅ Different numbers for different purposes

  • ✅ Scale linearly with hardware

Considerations:

  • Each SIM needs separate Android device (or dual-SIM phone)

  • Each requires warm-up process

  • More devices to manage

  • Increased monthly costs

See: Multiple SMS Accounts Guide

When to Use Twilio Instead

If you need truly unlimited (thousands/day):

Consider Twilio A2P:

  • Volume: Unlimited (with scaling costs)

  • Cost: $0.0075-0.01 per SMS (adds up fast)

  • Infrastructure: Cloud-based, no devices

  • Use Case: High-volume transactional messaging

Compare:

  • 10,000 msgs/month via WhatSnap: ~$30 (3 SIMs)

  • 10,000 msgs/month via Twilio: ~$75-100

Recommendation:

  • WhatSnap: Best for 100-1,500 messages/day

  • Twilio: Best for 2,000+ messages/day if you need guaranteed delivery

  • Hybrid: Use both for optimal cost/performance


Best Practices for "Unlimited" Messaging

1. Choose the Right Carrier

Priority Factors:

  • Stated fair use limit (10,000+ SMS/month ideal)

  • Business plan options (higher tolerances)

  • Direct carrier (better than resellers)

  • Good reputation with WhatSnap community

Examples of Good Carriers:

  • 🇺🇸 Verizon Business, Lycamobile, TracFone (slow warm-up)

  • 🇦🇺 Aussie Broadband Business, Telstra

  • 🇬🇧 Smarty, Giffgaff

  • 🇳🇿 Warehouse Mobile ($4/month unlimited!)

See: SIM Plan Recommendations

2. Warm Up New Numbers

Critical for "Unlimited" Success:

Week 1:

  • Start: 10-20 messages/day

  • Gradual increase

  • Very slow sending rate

Week 2:

  • Increase to 50-100 messages/day

  • Still gradual

Week 3+:

  • Reach sustained volume (100-250/day)

  • Monitor deliverability

Why:

  • New numbers are watched closely by carriers

  • Sudden high volume = instant red flag

  • Gradual growth = legitimate business use pattern

See: Database Reactivations - SIM Warm-Up

3. Use WhatSnap's Outreach Module with Drip Mode

Use WhatSnap's Outreach Features:

  • Throttled sending: Maximum 1 SMS per minute

  • Randomized delays: Prevents batch appearance

  • Auto opt-out handling: STOP = Auto-DND

  • Time restrictions: Send only during business hours

Workflow Best Practices:

Trigger: Contact tagged for campaign

Wait: Random 1-60 minutes (spreads messages)

Send SMS: Personalized message

Rate: 1 message per minute maximum

Daily Cap: 100-250 (depending on warm-up status)

See: Outreach Module

4. Message Quality > Quantity

High-quality messages avoid blocks:

Do:

  • ✅ Personalize every message ({{first_name}}, {{company}})

  • ✅ Vary content (don't send identical messages)

  • ✅ Conversational tone

  • ✅ Respond to replies immediately

  • ✅ Respect opt-outs

Don't:

  • ❌ Send links in initial messages (major spam trigger)

  • ❌ Use identical message templates

  • ❌ ALL CAPS, excessive punctuation!!!

  • ❌ Spam keywords (FREE, LIMITED TIME, ACT NOW)

  • ❌ Ignore opt-outs

5. Monitor and Adjust

Daily Monitoring:

  • ✅ Check delivery success rate (target: >95%)

  • ✅ Monitor opt-out rate (target: <2%)

  • ✅ Track response rate (5-20% typical for cold DBR)

  • ✅ Watch for failed sends or errors

If Issues Arise:

  • 🛑 Reduce volume immediately

  • 🛑 Improve message personalization

  • 🛑 Check for spam-like content

  • 🛑 Contact carrier if necessary

  • 🛑 Consider backup SIM


Common "Unlimited" Misconceptions

Myth 1: "Unlimited Means I Can Send 10,000 Messages/Day"

Reality:

  • ❌ Carrier fair use limits apply

  • ❌ 100-250/day per SIM is typical sustainable volume

  • ✅ "Unlimited" means no WhatSnap-imposed caps or per-message fees

  • ✅ Scale with multiple SIMs for higher volume

Myth 2: "I Don't Need to Warm Up"

Reality:

  • ❌ Warm-up is absolutely required for sustained volume

  • ❌ Starting fast = almost guaranteed block

  • ✅ 2-3 week warm-up = sustainable long-term operation

Myth 3: "Unlimited = No Restrictions"

Reality:

  • ⚠️ Carrier terms of service apply

  • ⚠️ Spam content will get you blocked regardless of volume

  • ⚠️ Fair use doesn't mean abuse

  • ✅ "Unlimited" refers to WhatSnap platform, not external factors

Myth 4: "I Can Use the Cheapest SIM for Unlimited Messaging"

Reality:

  • ❌ Budget carriers (like Tello) have strictest limits

  • ❌ "Unlimited" plans with vague terms often have low actual limits

  • ✅ Better carriers cost more but support higher sustainable volumes

  • ✅ Direct carrier business plans are most reliable
