Troubleshooting
Common Issues & Solutions
Quick fixes for the most common questions.
The watch shows no location
- Check that the watch is on and the SIM has data left
- Go outdoors for a few minutes: GPS does not reach well indoors
- Tap "locate" in the app to request a fresh position
- Check that mobile data is enabled on the SIM (APN set by the operator)
The battery runs out fast
- Choose a less frequent location update in the app
- Keep video calls short: they use the most power
- Weak mobile signal makes the watch work harder
- Charge with the cable that came with the watch
No notifications on my phone
- Allow notifications for the app in your phone settings
- Check the notification settings inside the app
- Make sure the safe zones are drawn where you expect
- Check that the watch has mobile signal
Calls do not connect
- Make sure the SIM has voice minutes and caller ID
- Check that the number calling is in the watch's contacts
- Restart the watch

FAQ
Frequently Asked Questions
Yes. Wonlex 4G watches need a nano-SIM with mobile data and caller ID switched on, plus voice minutes if you want calls. The SIM is not included: you use your own prepaid or contract SIM, so there is no subscription to us. Remove the SIM PIN on a phone before you put it in the watch.
The watches use the 4G network, so a SIM from a Greek operator such as Cosmote, Vodafone or Nova with mobile data is what you need. Ask your operator that the plan includes data and caller ID. If you are unsure about your SIM, send us a message before you order and we will check it with you.
Wonlex watches are managed from the free SeTracker or SeTracker2 app for iPhone and Android, depending on the model. You scan the registration code of the watch, then add contacts, safe zones and school hours. We send setup instructions in Greek with every watch and help by phone or message if you get stuck.
Yes. Prepaid and contract SIMs from Cosmote, Vodafone or Nova both work, as long as the SIM has mobile data, call minutes and caller ID. Like every prepaid SIM in Greece, it is registered to its holder, so a parent usually takes it out in their own name. Remember to top it up: when the credit runs out, the watch stops sending its location.
On many 4G watches, voice calls run over VoLTE (voice over 4G). If the location shows normally in the app but calls do not connect, ask your operator whether the SIM and plan have VoLTE switched on. For your specific model, ask us.
It depends on how often the location updates and how many video calls are made. We do not yet have confirmed measurements per model, so check the usage in your operator's app after the first week and pick a plan with some headroom.
