Recent changes to WhatsApp’s security protocols have introduced stricter monitoring of **newly registered numbers**, leading to frequent blocks. This is a challenge for companies using the **unofficial WhatsApp API**, especially when working with **new eSIM numbers**.

To minimize the risk of blocking, it is crucial to “warm up” new numbers, gradually increasing activity and imitating human behavior to build legitimacy.

### Why Number Warming Is Important

- A newly registered WhatsApp number is often considered **suspicious**.
- Do **not scan the QR code immediately** after registering a number — wait several hours.
- Warming up establishes a **natural usage pattern**, reducing the chances of triggering anti-spam algorithms.

### Key Warming Activities

- Sending and receiving **messages**
- Making and receiving **calls**
- Posting **status updates**
- Joining and participating in **groups**
- Adding and saving **new contacts** in the phone’s address book

### Recommended Warming Period

- Minimum: **3–10 days**
- Recommended: **15 days** before using the number for production messaging
- ⚠️ Even with proper warming, there is **always a risk of blocking**

### Step-by-Step Warming Strategy

**Day 0**

1. Do not connect the new number immediately — wait a few hours.
2. Configure your WhatsApp profile (name, profile picture, details).
3. Make sure you have at least **20–50 contacts** saved in your phone.
4. Send a few test messages to 1–2 real contacts and receive replies.

**Day 1**

1. Start 3–6 private conversations with existing contacts.
2. Send a mix of text messages and media (images, short videos).
3. Receive replies to keep interactions two-sided.

**Day 2**

1. Increase to 10–15 conversations.
2. Send approximately **1 message per minute** with varied content.
3. Continue balancing between messages sent and received.

**Day 3**

1. Increase conversations gradually.
2. Participate in group chats if possible.
3. Send different message types (links, long texts, images, voice notes).
4. Keep traffic looking natural and two-sided.

**Day 4–7**

1. Create or join additional WhatsApp groups.
2. Participate actively (reply, react, send different types of media).
3. Post **status updates** to simulate human behavior.
4. Add new contacts to your phone and message them.

**Day 8–15**

1. Continue increasing the number of conversations and groups.
2. Use features like channels and communities.
3. Keep adding new contacts regularly.
4. Limit sending to **2 messages per minute**, max **6 hours per day**.
5. Avoid consecutive heavy usage for more than **3 days in a row**.

### General Tips

1. Activities must look **human and random**, not automated.
2. Always add a number to your contacts before messaging it.
3. Avoid **one-way messaging** — ensure you’re receiving replies.
4. Spread activity throughout the day instead of concentrating it.
5. Gradually increase volume and diversify interactions.

### ⚠️ Important Notes

- Even with proper warming, **WhatsApp can still block new numbers** — this risk cannot be completely eliminated.
- Warming significantly reduces the chances of blocking but does not guarantee full protection.
- Always have **backup numbers** ready in case one gets blocked.

✅ By warming up your numbers for at least **15 days** and gradually building activity, you maximize the chances of keeping them active and avoid sudden blocks from WhatsApp’s security systems.
