Network and Internet Enable or Disable Cellular Data Roaming in Windows 11

This tutorial will show you how to enable or disable cellular data roaming in Windows 11.

Some Windows 11 devices have a SIM card or eSIM in them that lets you connect to a cellular data network (ex: 5G), so you can get online in more places by using a cellular signal.

If your Windows 11 device doesn’t have a SIM card or eSIM, you can still connect to a cellular network by plugging in an external cellular device (also called a cellular modem or mobile broadband device). Either way, you must have a data plan from a mobile operator (ex: AT&T, T-Mobile, etc...) to connect.

Data roaming options determines if your cellular data connection stays on when your Windows 11 device is outside your mobile operator's network. To help prevent data roaming charges, you can selecting Don't roam.

If you do allow roaming, you can use cellular data when your Windows 11 device is in a roaming area. Depending on your data plan, you might pay more for data you use when roaming.

Reference:







1 Open Settings (Win+I).

2 Click/tap on Network & internet on the left side, and click/tap on Cellular on the right side. (see screenshot below)



3 Select Don't roam (off - default) or Roam (on) for what you want in the Data roaming options drop menu. (see screenshot below)
