When you have the “Connected, roaming” message as shown above, you know the SIM card is configured correctly and is connected to the internet. Follow these steps in the order shown if you followed the instructions here and are still having trouble.

1. Verify SIM is Activated

Login to your RTK Mobile account to see your Data plans and the ICCID number associated with each plan. The ICCID number is printed both on the credit card sized SIM carrier that your SIM was punched out of and on the SIM you put in the RT5. If you don’t know how to log into your account, you can verify the SIM status on the Activation page just by typing in the ICCID number. If it does not have a status of “Active” or “activated” you will need to associate a data plan with the SIM card.

2. Verify SIM is detected by RT5

Even though the SIM card is in the RT5, it could be seated incorrectly and not making contact.

If you are replacing a SIM card with a new one, it is best to start the RT5 without a SIM card inside before turning it off and putting the new one in.

3. Use RTKMobileAPN.bat to set APN

Power the RT5 off with the SIM out, turn it on and power it back off to put in the SIM. Download this zip file containing the batch files to set the APN. Unzip them and run RTKMobile.bat. Go to Windows start and search for “Run” and then browse to where you unzipped the files and choose RTKMobile.bat. You will get a Windows warning screen. Click More Info and the the “Run Anyway” button. You will get a security warning in a terminal where you press R. After exiting the terminal, you will need turn on Roaming. Wait two minutes after running the program to see if it gets connected. If not, power off the RT5 and back on again.

Connecting to the internet using an RTK Mobile SIM card

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.run

Note: Ignore RT5 Control Center

Do not be concerned if the 4G control is shown as off. It does not affect the Cellular modem.

RT5 instructions apply to both the RT5 and RTk5.

Activate SIM

Use your phone camera to scan the QR code on your SIM card holder or Click Here to type the ICCID in and make sure your SIM card has been activated. The ICCID is printed on the SIM card holder QR label and on the SIM itself. If it is not activated, buy a data plan subscription and associate it with the SIM.

Check for CELL Support

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. If the Cellular icon is not there, then your tablet may not support Cellular or the drivers may need to be installed. Here’s how to check if your tablet supports Cellular.

Install SIM

1. Turn off the RT5 by selecting “Shut down” from the power icon on the welcome screen or in the Windows menu.
2. Remove the battery door by disengaging the safety and sliding the battery lock switch to the unlocked position and hold.
3. Remove the battery by pulling up on the battery next to the recessed plastic.
4. Unscrew battery cover with small Phillips screwdriver (4 screws).
5. Insert the nano SIM (smallest cutout) in the sim slot closest to the center of the RT5 until it clicks in.
6. Replace the metal cover with screws(4) that protect the SIM, replace the battery, engage safety switch.

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. Also try restarting the tablet. If still not working, follow the RT5 | RTk5 Troubleshooting Checklist.

Now you can configure Carlson SurvPC or Carlson Layout to send RTK corrections to your GNSS receiver.
