Can a MacBook use an eSIM?
No, and it helps to be clear about why so you do not waste an afternoon digging through settings that are not there. Apple has never shipped a MacBook with built in cellular. There is no SIM tray, no eSIM slot, and nothing in macOS to scan a carrier QR code into. That is true for the MacBook Air, every MacBook Pro, the old Intel machines, and the newer M1, M2, M3 and M4 models. If a site tells you to "install an eSIM on your MacBook" by opening Settings and adding a cellular plan, that menu simply does not exist on a Mac.
Plenty of other Apple devices do support eSIM, which is where the confusion comes from. iPhones, cellular iPads, and the cellular Apple Watch all take eSIM profiles. You can see the full breakdown on our eSIM compatible devices page. Laptops are the current exception in Apple's lineup.
What about future MacBooks?
This is expected to change. The industry widely anticipates Apple adding built in cellular and eSIM support to the Mac within the next couple of years, the same way cellular eventually came to the iPad. When an eSIM capable MacBook arrives, you will be able to install a Citrus Mobile eSIM directly on it, with no phone needed, exactly like you would on a modern eSIM laptop today. The setup in this guide is what works right now, and it will keep working as a backup even after Macs gain their own cellular.
The good news for today
You do not actually need cellular hardware inside the MacBook to get online. You just need the MacBook to reach the internet, and the cleanest way to do that anywhere in the world is to borrow the connection from a phone that already has a Citrus Mobile eSIM.
So how do you get a MacBook online when there is no Wi-Fi?
You tether. Your phone connects to a local mobile network using a Citrus Mobile eSIM, and then it shares that connection with your MacBook. To the MacBook it just looks like a normal Wi-Fi network, so everything works the way it always does. Mail, Safari, Slack, Zoom, Figma, your code editor, cloud backups, all of it.
This is the same approach digital nomads and remote workers have used for years, except instead of buying a fresh local SIM in every country and fiddling with carrier settings, you load one Citrus Mobile eSIM once and it keeps working as you move. When you cross a border, it connects to a carrier in the new country automatically. There is nothing to swap and no new account to set up.
How Citrus Mobile gives you internet almost anywhere
The reason this setup is so reliable comes down to how the eSIM connects. It is not tied to a single carrier. When you arrive somewhere, it looks at the available networks and connects to one with strong coverage, and it can switch as you travel. So you are not stuck hoping that one specific network reaches the cabin, the conference center, or the mountain town you are working from. As long as some carrier nearby has a signal, you have internet.
It covers 200+ countries on a single eSIM, the data is pay as you go starting from a $4 top up, and your balance does not expire on a timer. You pay for what you use at wholesale style rates rather than a fixed daily fee, which suits the uneven way laptop work actually happens. Some days you barely touch it, some days you upload a 3 GB video.
Set up your MacBook in a few minutes
You only do the eSIM part once. After that, getting your MacBook online is just turning on the hotspot.
If your phone is an iPhone
- 1
Install the Citrus Mobile eSIM on your iPhone
Create an account, top up from $4, and add the eSIM by scanning the QR code or installing it directly. Our how it works page walks through it.
- 2
Turn on Personal Hotspot
On the iPhone go to Settings, then Personal Hotspot, and switch on Allow Others to Join.
- 3
Connect the MacBook
Click the Wi-Fi icon in the top right of your Mac and pick your iPhone from the list. If both devices are signed into the same Apple ID, it often shows up without even needing the password.
- 4
Work as normal
The MacBook now uses the iPhone's Citrus Mobile data. For heavier sessions, plug the iPhone into the Mac with a cable, which gives you USB tethering plus charging and is steadier than Wi-Fi.
If your phone is an Android
- 1
Install the Citrus Mobile eSIM on your Android phone
Add it under Settings, then Network and internet, then SIMs, then Add eSIM, and scan the QR code.
- 2
Turn on the mobile hotspot
Go to Settings, then Network and internet, then Hotspot and tethering, and enable Wi-Fi hotspot. Set a password while you are there.
- 3
Join from the MacBook
Open the Wi-Fi menu on your Mac, choose the hotspot name, and enter the password.
- 4
Use USB for the steadiest connection
macOS also supports USB tethering from many Android phones, which avoids Wi-Fi congestion in busy places.
How much data does a MacBook actually use?
Laptop work uses more data than phone browsing, mostly because of video calls, file syncing, and software updates. These are rough hourly figures so you can size a top up. Real numbers vary with quality settings.
| What you are doing | Rough data use |
|---|---|
| Email, messaging, and docs | 5 to 15 MB per hour |
| Web browsing and research | 30 to 70 MB per hour |
| Slack or Teams chat | 10 to 30 MB per hour |
| Music streaming | 50 to 100 MB per hour |
| HD video call on Zoom or Meet | 500 to 900 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 macOS update | 1 to 5 GB or more, one time |
A typical remote work day of email, docs, chat, and a couple of calls lands around 1 to 2 GB.
A practical tip
Turn off automatic cloud photo backup and pause large macOS updates while you are tethering. Those are the two things that quietly eat the most data on a Mac, and they are easy to run later on free Wi-Fi.
What it costs
There is no plan to choose and no subscription. You top up a balance, and data is billed as you go. Larger top ups earn bonus credit, so the more you load the cheaper each gigabyte gets. Because rates vary by country, the clearest way to see your destination is the live rates page, and the pricing page explains exactly how billing works. For most travelers the cost lands well under what carrier roaming or daily plan fees would run for the same usage.
MacBook internet options compared
Tethering a MacBook to a Citrus Mobile eSIM is not the only way to get online, but it is the most flexible for people who move around. Here is how it stacks up against the usual alternatives.
| Option | Coverage | Reliability | Cost shape |
|---|---|---|---|
| Citrus eSIM on your phone, tethered | Works in 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 happen to find it | Hit or miss, often slow and shared | Free, but unpredictable |
| Pocket Wi-Fi rental | Usually one country per device | Decent, but one more thing to charge and carry | Daily rental plus a deposit |
| Home carrier roaming | Wherever your carrier has partners | Good, but you cannot switch networks | Often pricey daily or per MB fees |
Public Wi-Fi also brings a security angle worth keeping in mind. We cover that in detail in eSIM vs public Wi-Fi for laptops, but the short version is that your own tethered connection is far safer than an open network you do not control.
Troubleshooting common hotspot problems
- MacBook will not see the hotspot. Make sure Personal Hotspot or the Android hotspot is actually on, then toggle Wi-Fi off and on once on the Mac. On iPhone, having Bluetooth on helps it appear faster.
- It connects but pages will not load. Check that the phone itself has data and a Citrus Mobile balance. If the phone is online but the Mac is not, forget the network on the Mac and rejoin.
- Speeds feel slow. Move closer to the phone, or switch to a USB cable, which is almost always faster and steadier than Wi-Fi tethering in crowded places.
- The phone battery drains fast. Hotspots are power hungry. Keep the phone plugged in during long sessions, or use the cable so it charges while it tethers.
- It keeps dropping when the phone locks. On iPhone, keep the Personal Hotspot screen open or plug in via cable. On Android, disable battery optimization for the hotspot.
Where this works
Anywhere with mobile coverage, which is most of the inhabited world. The same eSIM that powers your MacBook in a Lisbon cafe works in Tokyo, Mexico City, or a train through the Alps. Browse coverage and rates by region for Europe, Asia, North America, South America, Africa, and Oceania, or look up a specific country on the rates page.
