Which laptops can use an eSIM directly?
It depends entirely on whether the laptop has cellular hardware inside it, often labeled WWAN, LTE, or 5G. Most laptops do not. The ones that do are usually business class machines where mobile connectivity was a buying option. If your laptop has it, you can install an eSIM right in the operating system. If it does not, no software update can add it, and you tether from your phone instead.
Laptops that often support a native eSIM include:
- Microsoft Surface models with LTE or 5G, such as Surface Pro and Surface Laptop cellular editions. See eSIM for Microsoft Surface.
- Lenovo ThinkPad models ordered with the WWAN option. See eSIM for Lenovo ThinkPad.
- Some Dell Latitude and HP Elite or EliteBook business laptops with mobile broadband. See eSIM for Dell laptops and eSIM for HP laptops.
Laptops that cannot use an eSIM directly, and therefore tether, include every MacBook (here is why), most consumer Windows laptops without the cellular option, most Chromebooks, and nearly all gaming laptops. Not sure which camp you are in? Check Settings for a cellular or mobile network section, or look up your exact model. Our eSIM compatible devices page has more detail.
If your laptop has no eSIM slot, do this instead
You tether. Your phone connects to a mobile network with a Citrus Mobile eSIM, then shares that connection to the laptop over Wi-Fi or a USB cable. To the laptop it is just another network, so everything works normally. This is how most people keep a laptop online on the road, and it is genuinely reliable for full days of work.
The advantage over buying a local SIM in each country is that you set up the eSIM once and it keeps working as you travel. Cross a border and it connects to a carrier in the new country on its own. No swapping cards, no new top up account, no hunting for a phone shop on arrival.
Why one eSIM works across the whole world
A Citrus Mobile eSIM is not locked to a single carrier. When you arrive somewhere it connects to a local network with good coverage, and it can switch networks as you move. So your laptop stays online even where one specific carrier would have dead spots. As long as some network nearby has a signal, you have internet.
One eSIM covers 200+ countries, the data is pay as you go from a $4 top up, and the balance does not expire. You are billed for what you actually use rather than a flat daily fee, which fits the uneven rhythm of laptop work where a quiet email day sits next to a day of big uploads.
Setup: native eSIM on a Windows laptop
If your laptop has built in cellular, you can add the eSIM directly in Windows.
- 1
Open cellular settings
Go to Settings, then Network and internet, then Cellular. If you see this section, your laptop has the hardware.
- 2
Add an eSIM profile
Choose Manage eSIM profiles, then Add a new profile, and scan or enter the Citrus Mobile activation details from your account.
- 3
Turn cellular on
Enable the profile and let Windows connect. Your laptop now has its own mobile data, no phone required.
- 4
Top up and go
Manage your balance from your Citrus Mobile account. The same data rules apply, pay as you go across 200+ countries.
Setup: phone hotspot for any laptop
This works for every laptop, Windows, Mac, or Chromebook.
- 1
Install the Citrus Mobile eSIM on your phone
Top up from $4 and add the eSIM by QR code or direct install. The how it works page covers it.
- 2
Turn on your phone hotspot
On iPhone use Settings then Personal Hotspot. On Android use Settings then Network and internet then Hotspot and tethering.
- 3
Connect the laptop
Open the laptop Wi-Fi menu, pick your phone, and enter the hotspot password.
- 4
Use a cable for heavy work
USB tethering is steadier than Wi-Fi in busy places, and it charges the phone at the same time.
How much data does laptop work use?
Laptops use more data than phones, mainly from video calls, file syncing, and updates. Use these rough hourly numbers to size a top up.
| Activity | Rough data use |
|---|---|
| Email, docs, and messaging | 5 to 15 MB per hour |
| Web browsing and research | 30 to 70 MB per hour |
| Video call on Zoom, Teams, or Meet | 500 to 900 MB per hour |
| Music streaming | 50 to 100 MB per hour |
| Standard video streaming | 0.7 to 1.5 GB per hour |
| Large file or video upload | Roughly 1 GB per GB sent |
| Cloud backup or OS update | 1 to 5 GB or more, one time |
A normal remote work day usually lands around 1 to 2 GB. Streaming and big uploads push it higher.
Save data without thinking about it
Pause cloud backups and OS updates while you tether, lower video call quality to standard definition, and let big downloads wait for free Wi-Fi. Those few habits cut laptop data use sharply.
What it costs
No plans, no subscription. You top up a balance and pay for data as you use it, with bonus credit on larger top ups so each gigabyte gets cheaper the more you load. Rates vary by country, so check your destination on the rates page, and see the pricing page for exactly how billing works. For regular travelers it usually costs less than carrier roaming or per country pocket Wi-Fi rentals.
Laptop internet options compared
| Option | Coverage | Reliability | Cost shape |
|---|---|---|---|
| Citrus eSIM, native or tethered | 200+ countries, switches carriers automatically | High, follows the best local signal | Pay as you go from $4, no daily fee |
| Cafe and hotel Wi-Fi | Only where you find it | Inconsistent and often slow | Free but unpredictable |
| Pocket Wi-Fi rental | Usually one country per device | Fine, but extra hardware to carry | Daily rental plus deposit |
| Carrier roaming | Your carrier's partner networks | Good, but locked to one network | Often expensive daily or per MB fees |

Troubleshooting
- Laptop cannot find the hotspot. Confirm the hotspot is on, then toggle the laptop Wi-Fi off and on. Keeping Bluetooth on helps an iPhone appear faster.
- Connected but no internet. Check the phone itself has data and balance. If the phone is fine, forget the network on the laptop and rejoin.
- Slow speeds. Move closer to the phone or switch to a USB cable, which beats Wi-Fi tethering in crowded areas.
- Phone battery draining. Keep it plugged in or use a cable so it charges while sharing data.
- Native eSIM not connecting on Windows. Make sure the profile is enabled under Cellular settings and that airplane mode is off.
Where this works
Anywhere with mobile coverage. The same eSIM that powers your laptop in one country works across borders without changing anything. Browse rates by region for Europe, Asia, North America, South America, Africa, and Oceania, or check a specific destination on the rates page.
