Does the MacBook Air have an eSIM?
Not at the moment. The MacBook Air does not ship with cellular hardware, across every Intel model and the M1, M2, M3, and M4 versions. There is no SIM tray and nothing in macOS to add a cellular plan today. It is the same story as the rest of the range, explained on the eSIM for MacBook page.
Apple is expected to add cellular and eSIM support to the Mac in the next couple of years, and when an eSIM capable Air arrives you will install a Citrus Mobile eSIM straight on it. For now that is not really a problem for how the Air is used. It is the laptop people throw in a bag for a month of travel, and the lightest way to keep it connected today is to lean on the phone you already carry.
The travel laptop setup
The whole appeal of the MacBook Air is that it disappears into your bag. So the right internet setup should not add a pocket Wi-Fi puck to charge or a local SIM to chase down on arrival. Tethering keeps it minimal. Your phone runs a Citrus Mobile eSIM, and the Air joins it like any Wi-Fi network.
Great for long battery days
The Air sips power, so a typical workday of writing, browsing, and a few calls barely dents either device. For longer sessions, tether over a cable so the phone charges while it shares data.

Travel with it
Cross a border and it reconnects to a strong local network on its own. Nothing to swap.
How much data will you use?
The Air is usually a lighter-use machine, which is good news for your balance.
| Activity | Rough data use |
|---|---|
| Writing, email, docs | 5 to 15 MB per hour |
| Web browsing and research | 30 to 70 MB per hour |
| Video call | 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 |
A normal travel-and-work day on a MacBook Air often comes in under 1.5 GB.
What it costs
Pay as you go from $4, with bonus credit on larger top ups and rates that vary by country. See the rates page and pricing page. Because the Air is light on data, a single top up tends to stretch across a long trip if you keep streaming in check and let backups wait for free Wi-Fi.
Why it works everywhere you go
A Citrus Mobile eSIM is not tied to one carrier. It connects to a strong local network wherever you are and switches as you travel, so your MacBook Air has a working connection in 200+ countries on one balance. No new SIM at each stop, no roaming bill shock.
