Segway Max Plus (2.3) QuickLink SIM Replacement

This guide shows how to access and replace the SIM card in a Segway Max Plus (2.3) with an NB-Y Queclink ZK601 dashboard IoT.

Before You Start

Replace the SIM in one scooter first. Confirm that scooter comes back online before opening the rest of the fleet.

What You'll Need

• The activated replacement SIM supplied for the scooter
• The matching driver for the screws beneath the dashboard panel
• A plastic opening tool
• A clean, dry work surface and a small container for screws
• A phone with the Levy Operator app for post-replacement configuration

Power the Scooter Down

1. End any active ride and turn the scooter off.
2. Remove the main battery or otherwise disconnect the scooter from power.
3. Wait at least 30 seconds before opening the dashboard.

Step 1: Open the Center Dashboard Panel

The access point is the black center dashboard panel. You do not need to remove the entire handlebar or dashboard assembly.

Open the dashboard repair video at about 6:55 to see the panel opened.

Remove the screws from beneath the black center panel, as shown around the seven-minute mark in the repair video.

1. Support the black center panel with one hand.
2. Remove the screws from the underside of the panel.
3. Lift the top cover slowly. Do not pull on the wiring harnesses.
4. If the cover resists, check for a missed screw instead of forcing it open.

Step 2: Confirm the ZK601 Dashboard IoT

Compare the opened dashboard with the reference photo below. The board label should identify the Queclink ZK601 family used by the NB-Y IoT.

Step 3: Replace the SIM

1. Locate the removable SIM holder in the opened IoT.
2. Before removing the old SIM, take a close photo showing its notched-corner orientation.
3. Release or slide out the old SIM using the holder's normal movement. Do not lift or bend the metal holder.
4. Insert the replacement SIM in the same orientation.
5. Confirm the replacement sits flat and fully seated. Do not force it.

Step 4: Close the Dashboard

1. Confirm the SIM is seated and no loose screws or tools remain inside.
2. Place every harness back in its original path so no wire is pinched by the cover.
3. Check that the panel's seal or gasket is clean and correctly seated.
4. Lower the black top cover into place.
5. Reinstall the underside screws evenly until snug. Do not overtighten them into the plastic.
6. Reconnect the battery and power the scooter on.

Step 5: Configure and Verify the Scooter

After a SIM change, confirm the cellular settings and connection:

1. In the Levy Operator app, open the scooter and tap Queclink BLE.
2. Follow Configure Queclink IoT from the Operator App to apply the correct APN, server, and port.
3. Allow one to two minutes for the IoT to reboot and reconnect.
4. In Levy Fleets Dashboard > IoT Devices, search for the scooter by IMEI.
5. Confirm it shows Online with recent telemetry before replacing SIMs in other scooters.

Troubleshooting

The scooter does not appear in Queclink BLE

• Stand within a few feet of the scooter
• Confirm Bluetooth and Location permission are enabled
• Make sure the scooter has power
• Power-cycle the scooter and scan again

The scooter stays offline after configuration

• Reopen the dashboard and confirm the SIM is fully seated
• Use Read Current Config in Queclink BLE to confirm the new settings were saved
• Wait a full two minutes after the IoT reboots
• Contact support@levyelectric.com with the scooter IMEI, a photo of the ZK601 label, and a close photo of the SIM holder
