SIM Card Warmup

🚨 Why it’s important:

Mobile carriers use spam filters and algorithms to track how texts are sent.

If you blast out too many messages too quickly (especially without getting replies), your SIM is at risk of being flagged, throttled, or even blocked.

✅ What carriers like to see:

Gradual, consistent activity (not sudden bursts)

Real conversations — not just outgoing messages

Replies that show you're engaging with real people

🔥 Our recommended SIM warm-up plan:

For the first 3–5 days after activating your SIM:

Start by texting at least 15 different people — friends, family, coworkers, or even warm prospects

Keep it real: aim for genuine, two-way conversations

Avoid sending bulk or identical messages during this time

💡 Think of it like building trust with the carriers. The more natural your early activity looks, the more freedom you'll have later to send at higher volume without getting flagged.
