You bought a GPS tracker, opened the manual…
And there are no SMS commands inside 😐

Or even worse:

• the manual is missing
• you bought the tracker second-hand
• important commands (like server setup) are not listed

Take it easy — this is frustrating, but usually solvable.

Let’s go step by step 👇

🔍 1. Start with the manufacturer’s website

If your tracker has a recognizable brand, this is your best starting point.

Examples:

• Sinotrack
• Gosafe
• Megastek
• Meitrack
• TKSTAR
• Wonde Proud

👉 Go to the official website
Most manufacturers provide:

• product pages
• downloadable PDF manuals

These often contain the full command list, even if your printed manual doesn’t.

🌐 2. Use Google (seriously, it works)

Search for:

[tracker model] sms commands

Or:

[model] apn setup gps tracker

💡 Tip:
Don’t rely on just one source — compare a few results.
(Although sometimes the first result is all you need 😄)

🧠 3. Use the commands you already have

Sometimes your manual includes a few commands, like:

• APN setup
• working mode

👉 That’s a clue.

Take one known command and search for it.

Example:

apn123456 internet

📌 This often leads to:

• full manuals
• complete command sets
• including server configuration commands

👥 4. Check forums and communities

Other users have likely faced the same issue.

Look for:

• GPS tracker forums
• Reddit discussions
• blog comments

👉 People often share:

• working commands
• real-world tips
• model-specific quirks

🛰 5. Use ready-made platforms and databases

For example, on LiveGPSTracks:

• there’s a list of supported devices
• many models include a “How to configure” section
• with ready-to-use commands

👉 This can save you a lot of time.

⚠️ 6. Found commands, but they don’t work?

Very common.

Reason:
👉 same model name ≠ same device

This is especially true for generic Chinese trackers.

What to do:

• check the device carefully
• look at the label or packaging
• find additional markings

Example:

TK905 ≠ TK905B ≠ TK905-4G

👉 Always search using the full model name.

🤯 7. Found multiple command sets?

Yes, that happens.

Reality:
👉 sometimes you’ll need to test different commands

Tips:

• don’t send everything blindly
• test carefully
• note what works

✉️ 8. Contact the manufacturer or seller

If nothing works — this is completely normal.

👉 Reach out and ask for:

the full SMS command list

This is a standard request.

🚫 Important: your tracker might be locked

If there is no server configuration command, it may mean:

👉 the tracker only works with:

• the manufacturer’s platform
• or a limited set of approved services

📌 In that case:

• connecting it to platforms like LiveGPSTracks may not be possible

You’ll need to decide:

• keep using it as is
• or return/replace it

(We’ll cover pros & cons of locked devices in a separate article 👌)

✅ Final thoughts

Missing SMS commands is not a dead end.

In most cases, the solution is:

1. Manufacturer’s website
2. Google search
3. Using known commands
4. Community forums
5. Platforms like LiveGPSTracks

👉 The key is to stay calm and search methodically.

💡 And yes — often the first Google result solves everything.
