When you insert SIM card and there is no Internet, highly likely that you need to enter the Access Point Names (APN) manually into your Oudie N / Omni.
You can find these settings in Android Settings > Network & Internet > Mobile Network > Advanced > scroll to the end of the list > Access Point Names. You will have to edit or add APNs for your operator.
Please turn to your SIM card provider to find the correct APN settings (normally ask it in the place where you bought your SIM card).
How to setup a new APN
Follow these steps. At first you need to go to Android settings (at the bottom of the applications page):

- Go to Android settings > Network & Internet > Mobile Network > Advanced > Access Point Names (APN).

- Tap on the “+” item at the top of the screen to enter a new APN
- Enter anything in the “name” field. It is free text, whatever helps you identify this SIM card

- Enter the APN field

- Tap on the three vertical points icon in the top-right corner and choose “Save”

- Make sure that you select the APN that you just entered
- Reboot the device, the Internet should work
