Need help? If you're unsure about any step, reach out to us at support@vemos.io or 877-388-7872 before getting started.
Part 1 — Replacing the SIM Card
- Power off the device and remove the back
- Lift the battery out and set it aside
- Locate the SIM slot — it will now be visible at the top left corner inside the device
- Insert the new SIM card
Important: Don't force the SIM in. If it's not going in smoothly, double-check the size and which way it's facing.
Putting it back together:
- Place the battery back in — line up the metal contacts with the pins inside
- Power the device back on
Part 2 — Setting Up the New SIM
Once the new SIM is in, you'll need to set up the APN so the device can connect to the internet.
What is an APN? APN stands for Access Point Name. It tells the device how to connect to the internet through your SIM card. Without this step, your device won't be able to scan IDs or process transactions.
- Turn the device on and swipe up to access the app menu
- Open the System Panel app (the Gear icon)
- Enter the password: 00000000 (eight zeros) in both fields, then tap the checkmark
- Scroll down and tap Settings
- Tap Network & Internet
- Tap SIMs
- Scroll down and tap Access Point Names
- Tap the + button to add a new APN
- Tap Name, type wbdata, then tap OK
- Tap APN, type wbdata, then tap OK
- Tap the three dots ⋮ in the top right and tap Save
- Tap the circle next to wbdata to select it as your active APN
- Tap back — if it worked, the data number shown will be above zero
- Tap back once more to exit — you're all set

Troubleshooting
🔴 Device isn't detecting the SIM?
Power off the device, remove the battery, and make sure the SIM is seated correctly in the slot with the gold contacts facing down. Reassemble and try again.
🔴 No signal after inserting the SIM?
Try moving closer to a window. Then go to Settings → Mobile Network and toggle Automatic Network off and back on.
🔴 Signal shows but no internet connection?
Make sure Mobile Data is turned on and that your APN name and settings are entered exactly as shown above (wbdata).
🔴 App won't load or scans aren't going through?
Double-check your APN settings and confirm the SIM has an active data plan. If everything looks correct, contact us at support@vemos.io or 877-388-7872.
🔴 Device is stuck on "Connecting"?
Power the device off and back on. If it's still stuck, reach out to our support team and we'll help you get sorted.
