First and foremost, make sure you have a properly inserted SIM card in your tablet and restart your device.
If you have a data SIM card from us and you do not have a network connection, please make sure that you have mobile data turned on in the tablet settings.
If you have mobile data turned on and still do not have an internet connection, you need to verify that the operator's LTE signal is in place. You can find this information on the official website of the operator - there could be some issue and most of the time really is.
Also keep in mind weather conditions that can result in internet outage crashes on the transmitter. You can find out this information again from your operator. The problem may also be caused by not enough mobile data on the SIM card. If you have a SIM card purchased from Storyous, contact our customer support, who will check the status of the data and can increase it immediately.
