I can't turn on the translator

1. Fully charge your translator.

2. When the translator is being charged, press and hold the volume up, volume down, and the power button (3 buttons in total) at the same time, and hold them for 30 seconds or until the translator is powered on.

3. Update your translator to the latest software version (Settings>System Update).

The global data coverage doesn't work when the first time I use the translator

Check your order history and make sure your translator comes with the built-in global data coverage. If your translator does not come with the data plan, go to jarvisen.com/data to purchase.

The global data coverage on your Jarvisen Translator is enabled by the eSim technology. It doesn't require any physical sim card (i.e. there is no sim card supposed to be shipped in the package). You should be able to see the 4G icon on the top left of the screen when your translator is using global data coverage.

If you don't see the 4G icon, please try the following steps.
1. Make sure your translator has been fully activated by following the steps after the device is powered on. Please note that you need to connect to Wifi for the first time in order to activate the translator.

2. Swipe down from the top of the screen to show the quick settings panel. Make sure the Mobile Data icon is turned on, and the Wi-Fi is off. You should be able to see the 4G icon on the top left of the screen.

3. If you still don't see the 4G icon. Restart your device by pressing the power button and select restart. After the device restarted, swipe down from the top of the screen to show the quick settings panel, and make sure the Mobile Data icon is turned on, and the Wi-Fi is off. WAIT up to 15 minutes until you see the 4G icon showing up on the top left corner of the screen. It may take some time to activate the global data coverage sometime.

The global data coverage doesn't work when I travel to another country 

When you travel to another country, which is on the supported list (https://www.jarvisen.com/pages/global-data-coverage), the translator should be able to automatically switch and connect to the local data network in that country.

If it doesn't work, please try the following steps.

1. Make sure the country you travel is on the supported list here https://www.jarvisen.com/pages/global-data-coverage

2. Swipe down from the top of the screen, and turn on "Mobile Data" and "Wi-Fi". Connect to a working Wi-Fi to make sure you have Internet access so that the device can get the activation signal from the local mobile network provider.

3. Wait for 5-10 mins, turn off "Wi-Fi" and only have "Mobile Data" turned on. Check if there is any 4G icon shown on the top left corner of the screen and see if the mobile data connection is working.

4. If not, restart the translator and repeat step 2 and 3 for one more time.

5. If it still doesn't work, contact us at jarvisen.com/support and we will reply to you promptly.
