2.2. Prepare and Install SIM Card
The ML100G tracker requires a Nano SIM card for network connectivity. Please ensure your SIM card meets the following requirements:
- If using your local SIM card, ensure it is enabled for SMS, internet data traffic, calls, and caller ID display functions.
- If using a Spionlink SIM card, recharge it via www.spionlink.com to get a data plan first.
Note: Spionlink SIM cards only work in specific countries (Russian Federation, North America: US, Mexico, Canada, Puerto Rico; Europe: Belgium, Bulgaria, Cyprus, Croatia, Czechia, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, United Kingdom, Switzerland). They provide 100KB free data and do not support SMS or call functions, and only work with MiCODUS GPS Trackers (except ML935).
Image: Spionlink SIM card and supported regions.
To install the SIM card:
- Locate the SIM card slot on the side of the tracker.
- Insert the Nano SIM card into the slot with the gold contacts facing down, ensuring it clicks into place.
2.3. Configure APN (Access Point Name)
The APN information is crucial for the tracker to connect to the internet. Obtain the exact APN name from your local SIM card provider. Take the tracker to a location with good signal for this operation.
Send an SMS command to the tracker's phone number:
- If there is no APN user and password:
apn,apn content#
Example:apn,internet# - If there is an APN user and password:
apn,apn content,apnuser,apnpasswd#
Example:apn,orange,orange,orange#
The tracker will reply with "SET APN ok" if the command is received, but it will only get online if the APN information is 100% correct.
2.4. Charging the Device
The ML100G uses a Type-C charging port. Connect the provided USB charging cable to the tracker and a power source. A full charge takes approximately 4 hours.

3.3. Working Modes
The ML100G offers multiple working modes to optimize battery life based on your needs:
- Tracking Mode (2-4 days battery life): GPS is ON, Network Connected. Enters sleep mode if static for more than 5 minutes.
- Power Saving Mode (5-7 days battery life): GPS is OFF, Network Connected. Uploads data by specific interval, data can be acquired at any time.
- Hibernate Mode (10-15 days battery life): GPS is OFF, Network Disconnected. Uploads by specific interval, only tamper alarm can wake up the device.
You can switch modes using SMS commands. For example, to set Realtime Tracking Mode (Mode 1) with 10-second moving upload and 3600-second static upload: MODE,1,10,3600#
To set Power Saving Mode (Mode 2) to start at 08:00 AM and upload every 1 hour: MODE,2,0800,1#
To set Hibernation Mode (Mode 3) to start at 08:00 AM and upload every 1 hour: MODE,3,0800,1#
Note: The key difference between Mode 2 and Mode 3 is that in Mode 2, the device can be woken up by SMS, call, and light sensor, while in Mode 3, it can only be woken up by the light sensor.

6. Troubleshooting
| Type | Use |
|---|---|
| Unable to connect to tracking platform | Check the APN and settings. Check whether the data service of SIM card is enabled. Check the balance of SIM card. |
| Tracker shows offline | Check whether external power is still connected. Check if the vehicle entered network blind area. Check the balance of SIM card. |
| Unable to locate | Make sure the top side facing upward without metallic things shielded. Make sure it's not in area with no satellite coverage. |
| Location drift | In area with poor GNSS signal (tall building around or basement), drifting may happen. Check whether vibration happens around to trigger the accelerator. |
| No command reply | Make sure command format is correct. Vehicle may be in network blind area. Make sure SIM card is well inserted and has SMS service. |
