RT5 instructions apply to both the RT5 and RTk5.

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

Click on “Network and Internet” settings in that same area.

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