## 2. Why VoidFix Gateway (Core Benefits)

1. **No A2P / 10DLC registration (SMS)** — SMS is sent from real SIM cards inside your own Android phones, so carrier A2P/10DLC registration, campaign vetting and brand fees are not part of the setup, and there is no **2–3 week approval wait**.

4. **No WhatsApp Business API needed** — connect your existing normal WhatsApp or WhatsApp Business number by scanning a QR code. No Meta approval, no Facebook Business verification, no per-conversation API fees.
5. **Real blue-bubble iMessage** — sent from real Apple iPhones. No Mac computer ever needed.
6. **One platform, three channels** — manage SMS, WhatsApp and iMessage from one brand, one support team, with the same integrations.
7. **Works with the tools you already use** — GoHighLevel, Zapier, Make, Zoho, HubSpot, N8N, Bitrix24, Pabbly, Bubble.io, plus a REST API.
8. **Two-way conversations** — receive replies in real time on every channel, including inside your CRM.
9. **Fast setup** — most customers are live in **under 5 minutes** (SMS and WhatsApp).

## 4. SMS & MMS Gateway (Android Phone + SIM)

### 4.1 What it is
The VoidFix SMS Gateway **turns any Android phone with an active SIM card into an unlimited bulk SMS and MMS gateway.** Your messages are sent from **your own real phone number** through your SIM, controlled from the VoidFix dashboard, your CRM, or the API.

Because messages come from a real SIM on a real device (not a virtual/VoIP number), you **do not need A2P/10DLC registration**, and you **don't pay per message** — you use the SIM plan you already have.

> **Important — carrier rules still apply.** Sending from your own SIM is a different route from A2P 10DLC, not an exemption from carrier rules. Mobile carriers can still filter or suspend lines that send high volumes or unsolicited messages, and many consumer SIM plans limit commercial bulk use. Message people who opted in, honour opt-outs, use **Number Warmup** and **Spintax**, and spread volume across several SIMs with the **Number Pool**.

- Portal: **https://sms.voidfix.com**
- Pricing page: **https://gateway.voidfix.com/sms-pricing**

### 4.2 How it works
1. You install the free **VoidFix Gateway Android app** on an Android phone with an active SIM.
2. The phone connects to your VoidFix account using **socket technology** — a permanent, live, two-way connection between the VoidFix server and your phone.
3. When you send a message (from the dashboard, GoHighLevel, Zapier, API, etc.), it reaches your phone **instantly** through the socket, and the phone sends it as a normal SMS/MMS from its SIM.
4. The phone instantly reports back whether the message was **delivered or failed** — no refreshing needed.
5. When a customer replies, the reply travels back through the same live connection and appears in real time in your dashboard or CRM.

**What you need:**
- An **Android phone** (one or more)
- An **active SIM card** with an SMS plan in each phone (unlimited texting plan recommended)
- A stable internet connection on the phone (Wi-Fi or mobile data)
- The free VoidFix Gateway Android app

## 6. iMessage Gateway (Real Apple Devices)

### 6.1 What it is
The VoidFix iMessage Gateway lets businesses send **premium blue-bubble iMessages** to Apple users from **real Apple iPhones** — automated from your CRM, workflows, or the API.

Why iMessage:
- **Blue-bubble trust** — iPhone users see a native iMessage, which feels personal and trustworthy
- **Very high open rates** (up to ~99%) and **higher response rates than SMS** (up to ~3x)
- **End-to-end encrypted** by Apple by default
- **No A2P registration** and **no Mac computer required**

- Portal: **https://imessage.voidfix.com**
- Pricing page: **https://gateway.voidfix.com/imessage-pricing**

### 6.2 How it works
Each **iMessage line** is a real iPhone with its own SIM/phone number and Apple account. VoidFix connects that iPhone to the platform so you can send and receive iMessages from your dashboard, CRM (e.g. GoHighLevel) or API. Replies come back into your dashboard/CRM in real time.

There are **two ways** to get a line:

1. **Bring Your Own iPhone** — you provide the iPhone and SIM; VoidFix connects it to the platform.
2. **Fully Managed** — VoidFix **buys, sets up and manages the iPhone and SIM for you**. You don't buy or handle any hardware. VoidFix only asks for your **ZIP code** so it can get a local SIM number for your line.

### 6.3 Sending limit
- Each iMessage line can message up to **50 unique contacts per day**.
- This limit keeps the number healthy and within Apple's sending limits.
- There are **no per-message charges** — continuing conversations with contacts is part of the flat monthly price.
- Need more daily reach? Add more lines (each line = +50 unique contacts/day).

### 6.4 iMessage features
- **Premium blue-bubble delivery** from real Apple devices
- **Two-way conversations** — replies arrive in real time
- **Rich media** — voice notes, video, images and GIFs
- **Number Warmup (NEW)** — protects the line's reputation
- **Contact Card branding** — share your business contact card (name/branding) so recipients recognize you
- **50 unique contacts per day per line**
- **No Mac computer required**
- **No hardware required** on the Fully Managed plan
- **Integrations** — GoHighLevel, Zapier, Zoho, N8N, HubSpot
- **REST API** — send messages, read messages by ID or status, resend
- **Dedicated onboarding support** (priority support on Fully Managed)

**iMessage + GoHighLevel:**
- Send iMessages directly from GHL workflows
- Receive replies back into GHL conversations
- Use iMessage in automation sequences
- Track message delivery and responses
- Plug into existing funnels and campaigns

### 6.5 iMessage setup
iMessage is set up **with the VoidFix team** (no self-serve trial):
1. **Book a call** — https://calendly.com/hello-voidfix/1-1-support-call-voidfix-gateway (or message on WhatsApp).
2. **Choose a plan** — Bring Your Own iPhone or Fully Managed.
3. **Device setup** —
   - *Bring Your Own iPhone:* prepare an iPhone with an active SIM; the team guides you through connecting it.
   - *Fully Managed:* share your ZIP code; VoidFix provisions the iPhone, SIM and Apple account for you.
4. **Integration** — the team helps connect your line to GoHighLevel, Zapier, Zoho, N8N or HubSpot.
5. **Warm up and start sending.**

### 6.6 iMessage pricing (per line)

| Plan | Monthly price | One-time setup fee | iPhone + SIM | Support |
|---|---|---|---|---|
| **Bring Your Own iPhone** ⭐ Most Popular | **$99 / month per line** | **None** | You provide | Dedicated support |
| **Fully Managed** | **$149 / month per line** | **$149 one-time** | **Included** — VoidFix supplies & manages | **Priority** dedicated support |

**Both plans include:** 50 unique contacts per day · voice notes, video & GIFs · Number Warmup · GHL, Zapier, Zoho, N8N & HubSpot integrations · Contact Card · no per-message fees · no integration fees · no bandwidth charges · cancel anytime.

**The $149 setup fee (Fully Managed only) covers:** device provisioning, SIM and account configuration, automation setup, and onboarding so your line is ready to send.

> ⚠️ Any older material mentioning iMessage at "$199/month", "$200 setup" or "$649" is **outdated**. Current pricing is **$99** (Bring Your Own iPhone) or **$149 + $149 setup** (Fully Managed).

## 12. Compliance, Security & Best Practices

### 12.1 Security
- Enterprise-grade security with **advanced encryption** protocols
- **99.95% uptime SLA**
- iMessages are **end-to-end encrypted** by Apple
- Your messages are sent from **your own numbers and devices**, giving you full control

### 12.2 Customer compliance responsibilities
Customers are responsible for following messaging laws in every country they send to, for example:
- **TCPA** (USA), **CAN-SPAM** principles, **GDPR** (EU), and local equivalents
- Obtain **consent** before messaging
- Always provide an **opt-out** (e.g. "Reply STOP to unsubscribe") and honor it
- Avoid messaging during **restricted hours**
- Follow **carrier**, **WhatsApp** and **Apple** usage policies
- No spam, scams, phishing, illegal or prohibited content

### 12.3 Deliverability & number-health best practices
- Turn on **Warmup** for new numbers and ramp up gradually
- Use **Spintax** and personalization — avoid identical mass messages
- Spread high volume across **multiple SIMs / WhatsApp accounts / iMessage lines**
- Message people who expect to hear from you; clean your lists
- Keep devices online, charged and the VoidFix service running
- For iMessage, respect the **50 unique contacts per day** per line
- Because SMS and WhatsApp run on regular consumer numbers/accounts, aggressive spam-like behavior can lead to the **carrier or WhatsApp restricting the number** — following these practices minimizes that risk

## 16. Frequently Asked Questions

### General

**What is VoidFix Gateway?**
A business messaging platform to send bulk SMS, MMS, WhatsApp and iMessage from one place, using real phones and numbers, with flat monthly pricing and no per-message fees.

**Why use VoidFix instead of Twilio or LeadConnector?**
No A2P registration or approval waits, unlimited messaging for a flat monthly fee instead of paying per message/segment, and setup in minutes. Most businesses save up to ~80%.

**How fast can I get started?**
SMS and WhatsApp: usually under 5 minutes. iMessage: after a short onboarding call with the team.

**Is there a free trial?**
Yes — 7 days free for SMS and WhatsApp, no credit card required. iMessage doesn't have a self-serve trial; book a call to get started.

**Are messages really unlimited?**
Yes on all paid SMS and WhatsApp plans. iMessage allows 50 unique contacts per day per line. No plan has per-message fees.

**Can agencies manage multiple clients?**
Yes — unlimited sub-accounts on every plan.

**Can I use more than one channel?**
Yes. SMS, WhatsApp and iMessage are separate subscriptions/portals you can combine.

**Do you offer custom integrations?**
Yes — the VoidFix development team can build custom integrations. Book a call to discuss.

### SMS

**What do I need to send SMS?**
An Android phone with an active SIM card and the free VoidFix Gateway app.

**Do I need A2P / 10DLC registration?**
A2P/10DLC registration is not part of the VoidFix setup, because messages are sent from real SIMs in your own Android phones rather than from registered virtual numbers. This is a different route, not an exemption from carrier rules: carriers can still filter or suspend lines that send high volumes or unsolicited messages, SIM plan terms may limit bulk use, and consent, opt-out and quiet-hours rules still apply. Use opted-in contacts, Number Warmup, Spintax and the Number Pool.

**Can I use an iPhone for SMS?**
No — the SMS gateway app runs on **Android** phones. (iPhones are used for the iMessage service.)

**Do you support two-way SMS and MMS?**
Yes, on all paid plans — send and receive replies, images, video and files.

**Who pays for the SMS?**
You use your own SIM's plan. VoidFix charges only the flat monthly subscription. An unlimited-text SIM plan is recommended.

**Can I add more phones?**
Yes — add extra SIMs for $10 each or upgrade (Lite 5 → Starter 20 → Professional 50 devices).

**Can I connect multiple SIMs to one GoHighLevel sub-account?**
Yes, with the Number Pool feature.

**What happens if my phone goes offline?**
The phone must be online with the VoidFix service running to send and receive. Messages show as pending/queued in the dashboard, and any that fail can be resent by ID or campaign. Keep the phone online, charged and the service running.

**Which countries does SMS work in?**
It works wherever your SIM card can send SMS. You send from a local SIM in the country you're targeting for the best results and lowest cost.

### WhatsApp

**Do I need the WhatsApp Business API?**
No. VoidFix works with your normal WhatsApp or WhatsApp Business app number — no API approval, no Meta verification, no API fees.

**Can I use a normal (personal) WhatsApp number?**
Yes. Both normal WhatsApp and WhatsApp Business accounts can be connected.

**How do I connect it?**
In wa.voidfix.com → Host → Add Account, then scan the QR code from WhatsApp → Linked Devices → Link a Device.

**Does my phone need to stay on?**
Yes, the phone must stay online for the linked connection to remain active.

**What is WhatsApp Warmup?**
A feature that gradually increases sending on new numbers to build trust and reduce the risk of blocks. Included in all paid plans.

**What's the difference between WhatsApp plans?**
Only the number of WhatsApp accounts: Starter 1, Growth 5, Business 10. Features are the same.

**Can I send voice notes and videos?**
Yes — voice notes, video, images and GIFs.

**Can WhatsApp get banned?**
WhatsApp may restrict numbers that are reported or send spam-like messages. Use Warmup, Spintax, message people who opted in, and avoid aggressive volume on new numbers.

### iMessage

**What do I need for iMessage?**
Either your own iPhone with an active SIM ($99/mo per line, no setup fee), or the Fully Managed plan ($149/mo per line + $149 one-time setup) where VoidFix supplies and manages the iPhone and SIM.

**Do I need a Mac?**
No, never.

**Do I need to buy hardware for Fully Managed?**
No. VoidFix supplies and manages everything. We only ask for your ZIP code to get a SIM number for your line.

**How many iMessages can I send?**
Each line can reach up to 50 unique contacts per day, with no per-message fees. Add more lines for more daily reach.

**What does the $149 setup fee cover?**
(Fully Managed only) Device provisioning, SIM and account configuration, automation setup and onboarding.

**Can I connect iMessage to GoHighLevel?**
Yes — send from GHL workflows, receive replies in GHL conversations, use in automations, and track delivery. Also works with Zapier, Zoho, N8N and HubSpot.

**Can iMessage reach Android users?**
iMessage reaches Apple users. To reach Android users, use the VoidFix SMS or WhatsApp service.

**Is there a free trial for iMessage?**
No self-serve trial. Book a call with the team to get your line set up.

### Billing & Account

**Can I cancel anytime?** Yes, from the dashboard. Cancellation applies at the end of the current billing period.
**Do you offer refunds?** No — payments are non-refundable once service access is granted or the trial ends. Use the free trial to test first.
**How do I update billing info?** Dashboard → Billing.
**Are there hidden fees?** No. No per-message, integration or bandwidth fees. The only one-time fee is the $149 setup for Fully Managed iMessage.
