## Quick Answers

### Can I use my personal phone for WhatSnap SMS?

**Yes**, you can use your personal Android phone and personal number with WhatSnap. However, we recommend:

* ✅ Use the **`whatsnap-blacklist` tag** to exclude personal contacts from syncing to GHL
* ✅ Consider using a dedicated business phone/SIM for cleaner separation
* ✅ Follow carrier fair use policies (don't mix high-volume business SMS with personal use)

See: [Preventing Personal Messages from Appearing in CRM](/whatsnap-docs/faq/sms/prevent-personal-messages.md)

***

### Can I port my Twilio or LeadConnector numbers to use with WhatSnap?

**Not directly**. WhatSnap SMS uses your personal SIM card number, not ported numbers. However:

* ✅ You can port Twilio/LeadConnector numbers to **another carrier**
* ✅ Then use that carrier's SIM in your Android device with WhatSnap
* ✅ Or keep Twilio as separate channel and use WhatSnap for P2P SMS

**Note**: WhatSnap cannot assist with porting. You must work with Twilio/GHL and your new carrier.

See: [How to Port Numbers](/whatsnap-docs/faq/sms/porting-numbers.md)

***

### Should I enable or disable RCS on my Android device?

**Usually disable** for WhatSnap SMS. Enable only if:

* ❌ **Disable RCS** (recommended): Using local SIM for standard SMS
* ✅ **Enable RCS** (exception): Using eSIM from another country over WiFi

See: [RCS Settings Guide](/whatsnap-docs/faq/sms/rcs-settings.md)

***

### Can I send MMS (picture messages) with WhatSnap SMS?

**Yes**, but with requirements:

* ✅ Image must be under 800 KB
* ✅ WhatSnap Gateway app must be set as **default SMS app** on Android
* ✅ Device must have adequate signal strength
* ✅ Test sending MMS directly from phone first

See: [Troubleshooting - MMS Not Sending](https://github.com/WhatSnap/documentation/blob/main/faq/troubleshooting/README.md#mms-not-sending)

***

### How many messages can I send per day with WhatSnap SMS?

**Depends on carrier and warm-up status:**

* **New SIM (Week 1)**: 10-20 messages/day
* **Warmed SIM (Week 2+)**: 100-250 messages/day
* **Maximum rate**: 1 message per minute sustained
* **Multiple devices**: Scale by adding more SIM cards

See: [Database Reactivations - Volume Guidelines](broken://pages/1NpMBh9RXUeVt9ElFXvj)

***

### Will my personal contacts see my business messages?

**No**, when properly configured:

* Messages sent through WhatSnap appear in your phone's native Messages app
* Replies from business contacts sync to GoHighLevel
* Use **`whatsnap-blacklist` tag** to exclude specific contacts from GHL sync
* Personal conversations stay in Messages app, business in GHL

See: [Preventing Personal Messages](/whatsnap-docs/faq/sms/prevent-personal-messages.md)

***

### Can I use the same phone for both personal and business SMS?

**Yes**, but we recommend against it for these reasons:

**Challenges:**

* ❌ Mixing personal and business messages gets confusing
* ❌ Harder to track business metrics
* ❌ Risk of accidentally syncing personal conversations to CRM
* ❌ Carrier may flag account for business use on personal plan

**Better approach:**

* ✅ Use dedicated device for WhatSnap SMS
* ✅ Get business-specific SIM plan
* ✅ Keep personal and business completely separate
* ✅ Or use `whatsnap-blacklist` tag religiously

See: [Device Specifications - Purchase Recommendations](https://github.com/WhatSnap/documentation/blob/main/faq/sms-specifications.md#purchase-recommendations)

***

### What happens if my SIM card gets blocked?

**Common scenario with solutions:**

**Immediate actions:**

1. **Stop sending** messages immediately
2. **Contact carrier** to request unblock
3. **Wait 24-48 hours** before resuming
4. **Reduce volume** significantly when you resume

**Prevention:**

* Follow proper [SIM warm-up process](https://github.com/WhatSnap/documentation/blob/main/faq/database-reactivations.md#sim-warm-up-process)
* Stay within carrier fair use limits
* Don't send spam-like content
* Use multiple SIMs to distribute volume

See: [Troubleshooting - SIM Card Blocked](https://github.com/WhatSnap/documentation/blob/main/faq/troubleshooting/README.md#sim-card-blocked)

***

### Can I use WhatSnap SMS internationally?

**Yes, with considerations:**

**Sending internationally:**

* ✅ Ensure your SIM plan includes international SMS
* ✅ May incur higher per-message costs
* ✅ Some carriers restrict international SMS on certain plans
* 💡 **Alternative**: Use WhatsApp for international (no SMS charges)

**Using eSIM from another country:**

* ✅ Can use eSIM over WiFi to send from that country's number
* ⚠️ Must enable RCS for eSIM over WiFi
* ⚠️ Check carrier supports eSIM SMS over WiFi

See: [RCS Settings - eSIM Over WiFi](/whatsnap-docs/faq/sms/rcs-settings.md#required-turn-rcs-on)

***

### How is WhatSnap SMS different from Twilio?

**Key differences:**

| Feature            | WhatSnap P2P SMS              | Twilio A2P SMS                     |
| ------------------ | ----------------------------- | ---------------------------------- |
| **Cost**           | Fixed ($10-30/month SIM plan) | Per-message ($0.0075-0.01 per SMS) |
| **Number**         | Your personal/business number | Dedicated business number          |
| **Setup**          | Android device required       | Cloud-based, no device             |
| **Volume**         | 100-250/day per SIM           | Unlimited (with scaling costs)     |
| **Deliverability** | Carrier-dependent             | 99.95% SLA                         |
| **Use case**       | Personal touch, DBR, local    | High-volume, transactional         |

**Best approach**: Use both

* WhatSnap for personal, conversational messaging
* Twilio for high-volume, transactional messages

***

### Do I need to keep my Android device on 24/7?

**Yes, for reliable operation:**

**Requirements:**

* ✅ Device powered on and plugged in
* ✅ Internet connection active (WiFi or mobile data)
* ✅ WhatSnap Gateway app running
* ✅ Battery optimization disabled
* ✅ Screen can sleep, but device stays awake

**Power management tips:**

* Use dedicated device (not daily-use phone)
* Keep plugged into charger constantly
* Disable screen timeout (or set to minimum brightness)
* Use power outlet with surge protector
* Consider backup power (UPS) for critical operations

See: [Installation - Device Configuration](https://github.com/WhatSnap/documentation/blob/main/faq/sms-installation-setup.md#device-configuration-best-practices)

***

### Can I use multiple SIM cards to increase volume?

**Absolutely! This is recommended for scaling:**

**Benefits:**

* 📈 Each SIM adds 100-250 messages/day capacity
* 🔀 Distribute load across multiple carriers
* 🛡️ Redundancy if one SIM gets blocked
* 👥 Assign different numbers to different teams

**Setup:**

* Connect multiple Android devices to WhatSnap
* Each gets unique tag (e.g., `whatsnap-account-android-1`, `android-2`)
* Use workflows to distribute contacts across devices
* Monitor each SIM's performance independently

See: [Multiple SMS Accounts Guide](/whatsnap-docs/account-management/sms/multiple-sms-accounts.md)

***

### What's the best Android device for WhatSnap SMS?

**Recommended specs:**

* **OS**: Android 9.0 or higher
* **RAM**: 4 GB (minimum 2 GB)
* **Brand**: Google Pixel, Nokia, Motorola (stock or light Android)
* **Avoid**: Very cheap phones (<$50), devices with aggressive battery management

**Top picks:**

* **Mid-range**: Google Pixel 3a/4a refurbished ($100-150)
* **Best value**: Refurbished Google Pixel (stock Android, reliable)

See: [Device Specifications - Recommended Devices](https://github.com/WhatSnap/documentation/blob/main/faq/sms-specifications.md#recommended-devices)

***

**Legal requirement - must honor immediately:**

**WhatSnap's auto-DND:**

* ✅ Contact replies "STOP" → Automatically added to DND
* ✅ All future messages blocked
* ✅ Works across all WhatSnap accounts

**Manual setup:**

* Create workflow: Trigger on SMS contains "STOP"
* Action: Add to DND
* Action: Tag "Opted-Out"
* Action: Remove all campaign tags
* Action: Send confirmation: "You've been unsubscribed"

**Compliance:**

* Must honor within 24 hours (recommend: immediately)
* Keep records of opt-outs
* Accept variations: STOP, UNSUBSCRIBE, CANCEL, END, QUIT

* ✅ Focus on **database reactivation** (old leads who opted in)

See: [Cold SMS Outreach Guide](/whatsnap-docs/faq/sms/cold-sms-outreach.md)

***

### Do I need A2P registration for WhatSnap SMS?

**No**, A2P (Application-to-Person) registration is **not required** for WhatSnap P2P SMS.

**Why:**

* WhatSnap uses **your personal/business SIM card** (P2P messaging)

See: [A2P Requirements Guide](/whatsnap-docs/faq/sms/a2p-requirements.md)

***

### Is WhatSnap SMS really unlimited?

**Yes and no** - it depends on what you mean by "unlimited":

**⚠️ Limited by external factors:**

* Carrier fair use policies (typically 100-250 msgs/day per SIM)
* Country regulations
* Android phone technical limits (30 msgs/30 min triggers warning)

**Scaling:**

* Add more SIMs to increase capacity
* 1 SIM = 100-250 msgs/day
* 5 SIMs = 500-1,250 msgs/day

**Cost Comparison:**

* WhatSnap: $30/month for 3,000-7,500 msgs (fixed)
* Twilio: $24-60/month for same volume (variable)

See: [Unlimited SMS Explained](/whatsnap-docs/faq/sms/unlimited-sms.md)

***

### Why should I use WhatSnap instead of Twilio?

**WhatSnap is better when you need:**

**✅ Speed:**

* Setup in 15-20 minutes (vs. 2-6 weeks for Twilio A2P)

**✅ Predictable Costs:**

* Fixed $10-30/month per SIM
* No bill shock

**✅ Personal Touch:**

* Your real phone number (not pool number)
