As WhatsApp continues to tighten its anti-spam measures, new phone numbers (especially those linked via eSIM) face a high risk of being flagged or blocked.

To minimize these risks, it’s important to gradually warm up new numbers by simulating organic usage patterns, which helps establish trust and reduce the likelihood of account restrictions.

This guide provides some essential best practices for warming up your number.

​
What Is Number Warming?

Number warming is the gradual process of introducing a new phone number to messaging activity in a way that mimics natural user behavior. This helps establish trust with platforms like WhatsApp, reducing the risk of temporary bans or permanent blocks—especially important when using new numbers

​
Steps to Warming Up Numbers

Successfully warming up a number typically takes 3 to 10 days. The goal is to simulate natural human behavior, not automated blasts. Here’s how to do it right:

⚠️ Once the number is connected, avoid immediately sending messages. Let it breathe and ramp up gradually.

​
1. Initial Setup Phase

  • Hold off on linking your freshly registered WhatsApp number to any other devices for a few days.
  • If possible, consider using a dedicated proxy located in the same country (or even better, the same city) as your actual device. This helps maintain consistency in your number’s digital footprint.
  • Next, complete your WhatsApp profile directly on your phone. Add a name, profile photo, and any other relevant details.
  • Make sure your contact list isn’t empty. Aim to have 20–50 saved contacts. If that’s not possible, add a few manually.
  • Finally, send a couple of genuine, handwritten messages to contacts you already know and try to get replies. Early back-and-forth conversation builds your behavior scores

​
2. Light Touch Engagement

  • Start a few private chats (3–6) directly from your phone with contacts you already know. Keep it natural and casual.
  • Send a few different types of messages. Avoid repetition and space them out.
  • Include some media in your conversations, like images, videos, or stickers, to reflect typical WhatsApp behavior.
  • Aim for replies. Getting responses to your messages helps establish normal engagement patterns.

​
3. Gradual Activity Increase

  • Start initiating more new conversations each day. Slowly scale up the volume to mimic organic growth.
  • Join and participate in group chats if available. Light, natural engagement is enough to show broader activity.
  • Send a greater variety of messages, including longer texts, links, and different content types to diversify behavior.
  • Make sure to respond to incoming messages. Sustained two-way communication signals healthy, human-like behavior.

​
4. Consistent Human-like Usage

  • Create new groups or join existing ones, and engage actively with members to simulate genuine participation.
  • Start using additional WhatsApp features—post status updates, follow or use channels, and try creating a community.
  • Keep increasing your daily message volume and continue varying the content—mix text, media, links, and emojis for a well-rounded activity profile.

​
5. Ready for Real Work

If no issues have come up, the number can now begin connecting your phone to other sessions and start your normal activity

Warming Up Tips

Here are some practical pointers to help your number blend in naturally and avoid getting flagged:

  • 🧠 Think like a human, not a bot. Keep your activity random and organic. Avoid predictable or repetitive patterns.
  • 📇 Save before you send. Always add the recipient to your contacts before initiating a conversation
  • 🚫 Don’t go overboard. Too many messages too fast or only sending messages without getting replies can trigger warnings.
  • 🕐 Spread activity across the day. Avoid message bursts at fixed hours; instead, pace interactions like a typical user would.
  • 📈 Increase gradually. Start small, then slowly scale up both the volume and variety of messages (text, emoji, media, etc.).

Bonus tips:

  • 🔁 Get replies. WhatsApp favors two-way conversations, so aim to get responses, not just deliver messages.
  • 🧪 Test before scaling. Try small volumes across a few numbers to see what works best before applying it at scale.
