Carlson RT3 | RT4 Tablet SIM Setup

All you have to do is install the SIM, then run RTK-Mobile-Setup.exe on your tablet. You do not need to activate the SIM first.

When you run it, Windows will show a "Windows protected your PC" security warning because the program is new to Microsoft Defender SmartScreen. Click More info, then Run anyway.

What the program does:

• Finds your cellular modem and inspects it for available SIMs or eSIMs
• Checks whether your SIM is activated and directs you to purchase a data plan for it if not
• Sets up your cellular network connection and sets your APN to flolive.net

If it reports that no Mobile Broadband cellular interface was found, it made no changes. Check that your tablet supports cellular, then use Manual setup instead.

If you are unable to run the program, use Manual setup instead.

Follow these steps to set up the APN by hand and, if needed, connect with Skylight.

Configure APN

In some cases the internet will start working without setting up the APN. This may happen when you connect with a T-Mobile tower, but it is temporary. You will still need to set up the APN on the data collector with the following instructions.

In the lower right area of the task bar, tap the Internet icon (three types of internet icons are circled in red below) and make sure that Cellular is enabled:

Click on Network and Internet settings in that same area.

In the Network and Internet settings dialog choose Cellular on the left side:

In the Cellular dialog, make sure that Roam is marked and go to Advanced options.

In Advanced options, click on "Add an APN".

Type in RTKMobile for the Profile name.

Type in flolive.net for the APN name.

Set APN type to "Internet and attach" or "Internet" if "Internet and attach" is not available.

"Apply this profile" should be on.

Everything else should be blank or marked as None or Default as shown below.

Click Save. Click on the back arrow at upper left to exit.

You should see the Cellular icon in the task bar. Tap the icon to see the Cellular status. It may take a few seconds to get connected.

Make sure the Cellular button is on as shown above and wait two minutes to allow time for the first connection until you see "Connected, roaming". Roaming is normal and you will not be charged extra for roaming. If Cellular status is still "No Service" tap the Cellular button to turn it off and again to turn it back on.

Downloading and Installing Skylight

Download Skylight on your RT3/RT4 by using WIFI or you can also save it to a thumb drive and copy it to your tablet. Do not download Skylight from the Microsoft app store. The Skylight version 4814 is specific for this modem and you may have problems seeing profiles with other versions.

Install Skylight with default options on the tablet.

Using Skylight to set the APN

Find the Skylight icon on the Desktop and double click it.

It should look similar to this:

Cleaning Up

Click on the wrench icon to get to the profiles.

Now click on profiles and then click on the Default profile. You may need to maximize the window and slide the dividing bar to the right to see the entire name of the profiles. Change the APN to flolive.net (make sure it is spelled correctly, all lower case and no spaces before or after). Just as you see in the picture below, delete any username and password, PDP type should be IPv4 or Default, and Authentication is set to None. Once that is done, click on Apply.

You can edit all other profiles. If there a lot of profiles, you can delete some that start with { instead of editing them with the black X at the bottom. If you can't edit or delete profiles, that usually means that you are already connected. Click on OK to confirm changes and exit User Options and go back to the main Skylight App. Windows might repopulate the one with "ProvisionedContextInternetProfile" as part of the name. This is normal as long as the APN is set up just like the Default profile we edited.

Connecting to the Internet

It might take a minute or two, but it should show this screen. If it doesn't give the option to connect, try using the drop down below the connect button to connect to a different profile. Some tablets will require turning cellular off and on again or a reboot and then checking the profiles again. There should only be profiles with APN flolive.net with the other settings as above. After it connects, the connect button will change to a Disconnect button.

You can now close Skylight and check the system tray internet button to check on the status.
