You may not be able to connect to your WWAN cellular network or swap from a 3G to 4G network. You may also receive a “No Service” error message from within Windows.
3G and 4G networks use different Access Point Names (APN) and must be manually selected within Windows. This will be more common as 3G networks are being retired by Internet Service Providers (ISPs).
Single Unit/Manual Change:
Update Windows and WWAN drivers to the latest version possible and then configure a new 4G APN.
- If you have a Dell DW5811e, DW5820e, or DW5821e card, update to the latest Snapdragon driver by visiting Dell.com/Support/Drivers
- Create a new APN by going to Network & Internet Setting > Cellular > Advance Options (Figure 1).
Figure 1
- Go to "Add APN" and enter your APN information (Figure 2).

- Ensure that "Apply to Profile” is checked.

Note: Dell DW5808e module Users will be required to reimage your computer or upgrade to a version of Windows greater than Windows 10 version 1903. Installing the latest DW5808e driver should also be done. On these modules, when configuring the APN, there may be no “Internet and Attach” option, but the new version of Windows will allow the computer to find the correct firmware without the 3G routing table.
