eSIM for Microsoft Surface: Install or Tether

Cellular Surface models are some of the easiest laptops to put a travel eSIM on. Here is how to install a Citrus Mobile eSIM on a 5G or LTE Surface, or tether a Wi-Fi only one.

Surface Pro and Surface Laptop models sold in 5G or LTE editions support eSIM and can install a Citrus Mobile eSIM directly under Settings, Network and internet, Cellular. Wi-Fi only Surface models have no cellular, so they tether to a phone. Either way, one balance covers 200+ countries with automatic carrier switching.

Which Surface models support eSIM?

Microsoft has offered cellular Surface devices for years, and they are a great fit for a travel eSIM because the modem is built in. eSIM works on the 5G and LTE editions of Surface Pro, including the recent Surface Pro with 5G, and on cellular versions of Surface Laptop and Surface Go. The key word is the cellular or 5G or LTE label. The standard Wi-Fi only versions of these devices do not have a modem.

To check yours, open Settings, then Network and internet, and look for Cellular. If it is there, you have a cellular Surface and can install an eSIM directly.

Install a Citrus Mobile eSIM on your Surface

On a cellular Surface this takes a couple of minutes and no phone is involved.

  1. 1

    Open cellular settings

    Go to Settings, then Network and internet, then Cellular. If this section exists, your laptop has the mobile hardware.

  2. 2

    Add an eSIM profile

    Choose Manage eSIM profiles, then Add a new profile, and scan or enter your Citrus Mobile activation details.

  3. 3

    Turn cellular on

    Enable the profile and let Windows connect. Your laptop now has its own mobile data, no phone required.

  4. 4

    Top up and travel

    Manage your balance from your Citrus Mobile account. Pay as you go across 200+ countries, with carrier switching handled for you.

A Surface bonus

Because Surface devices wake and connect quickly, a native eSIM means you open the lid and you are already online, even in a taxi or a terminal with no Wi-Fi. It is one of the smoothest cellular laptop experiences you can get today.

Got a Wi-Fi only Surface? Tether instead

If your Surface has no Cellular section, it is a Wi-Fi only model. You can still keep it online anywhere by sharing your phone connection.

  1. 1

    Put a Citrus Mobile eSIM on your phone

    Top up from $4 and install the eSIM by QR code or direct install. See how it works.

Why it works wherever you travel

A Citrus Mobile eSIM connects to a strong local carrier wherever you are and switches as you move, so your Surface stays online across 200+ countries on a single balance. There is no new SIM to buy in each country and no roaming plan to arrange.
