Does Microsoft Surface Have eSIM?
LTE and 5G Surface models have built-in eSIM. When purchasing a Surface, look for "LTE" or "5G" in the configuration name — these include cellular capability via eSIM. Standard Wi-Fi configurations have no cellular hardware at all.
How to check on your device: Go to Windows Settings → Network & Internet. If a "Cellular" section is present, your Surface has eSIM. If that section does not exist, your Surface is Wi-Fi only.

How to Activate eSIM on Microsoft Surface
- Press Windows + I to open Settings.
- Go to Network & Internet → Cellular.
- Click Add a cellular plan (or "Use a new eSIM profile").
- Choose Scan a QR code or enter activation details manually.
- Scan the QR code from your eSIM provider — Roamix emails it within 60 seconds.
- Follow the on-screen prompts to complete activation.
- In Cellular settings, toggle on Roam if you are using the eSIM abroad.
The eSIM downloads and activates over Wi-Fi. You do not need an existing cellular connection to install it.
Using Surface eSIM for Travel
A Roamix eSIM on your LTE Surface gives you mobile data in 190+ countries without carrying a Mi-Fi hotspot or relying on hotel Wi-Fi. Purchase a plan before departure, scan the QR code in Windows Settings, and your Surface connects automatically when you arrive.
Roaming setting: In Settings → Network & Internet → Cellular, ensure "Roam" is toggled on for the Roamix eSIM profile. Without this, your Surface will not use the eSIM on foreign networks.
Surface LTE models are ideal for business travelers who need reliable data for video calls and cloud access while moving between countries.
Surface eSIM Troubleshooting
No Cellular section in Settings: Your Surface is a Wi-Fi-only model with no eSIM hardware. LTE and 5G are separate hardware configurations — they cannot be added after purchase.
"Add a cellular plan" is greyed out: The eSIM may already be provisioned with a carrier plan, or there may be a Windows Update pending. Check for updates and restart.
eSIM active but no connection abroad: Go to Settings → Network & Internet → Cellular and confirm "Roam" is enabled. Without roaming enabled, the Surface will not connect to foreign networks on the travel eSIM.
How to switch between eSIM profiles on Surface: Settings → Network & Internet → Cellular → Manage eSIM profiles. Select the profile you want to use and click "Use."
