The iPhone 18 Pro and iPhone 18 Pro Max have no SIM tray in twelve countries and a nano SIM slot everywhere else. The iPhone Duo, the foldable Apple announced on the same day, has no tray in any market.

What Apple announced

Apple announced three phones on 9 September 2026, in press releases for iPhone 18 Pro and iPhone Duo.

How to use an eSIM as a hotspot

Fri, 03 Jul 2026 18:51:00 -0700

An Atli eSIM can supply your phone’s personal hotspot. Atli does not add a tethering fee or a separate hotspot allowance, but everything the connected devices use comes out of the active data plan.

Turn on Personal Hotspot on iPhone

Open Settings > Cellular or Mobile Service.
Under Cellular Data, select the Atli eSIM.
Return to Settings and open Personal Hotspot. On some iPhones it appears under Cellular.
Turn on Allow Others to Join.
Set a WiFi password, then choose the iPhone’s name from the other device.

If the other device uses the same Apple Account, Instant Hotspot may connect it without asking for the password.

Dual SIM abroad: keep your number

Most phones sold in the last few years can run two lines at once. That is what makes a travel eSIM worth having: your own number stays reachable while a second line carries the data at local prices, and you never choose between the two.

Who does what

Your home SIM handles your number, incoming calls, incoming texts and bank verification codes. The travel eSIM handles all mobile data: maps, messaging, browsing and calls made over WhatsApp or Telegram.

Can I use WhatsApp with a travel eSIM?

Sat, 20 Jun 2026 09:35:00 -0700

Yes. WhatsApp keeps using the number already registered to your account, and a travel eSIM supplies the data underneath it. You do not change your number, move your chats or tell anyone anything.

What a data-only eSIM actually is

A travel eSIM like Atli sells one thing: mobile data in a destination. It has no phone number attached, cannot send or receive SMS, and cannot make ordinary cellular calls. Every travel eSIM worth using works this way, and it is a design decision rather than a missing feature.

What is an APN, and should you change it?

Mon, 01 Jun 2026 14:08:00 -0700

An APN is a set of carrier instructions that tells your phone how to reach the internet over mobile data. Your phone normally receives those instructions with the SIM or eSIM profile.

If you use Atli, you do not need to type an APN. It is configured automatically. When data does not connect after you arrive, check which eSIM is selected for mobile data and whether data roaming is on before opening any advanced network menus.

Install your eSIM before you travel

Installing an eSIM needs an internet connection. That is why it is a job for before you go: if you wait, getting online requires already being online.

Why it has to happen at home

An arrivals hall is the worst place to discover that a phone is carrier-locked, or that the QR code needs a network to fetch the profile. Airport wifi means a captive portal and a queue, and the chat where you bought the plan cannot reach you through either.

Install your eSIM at home on reliable wifi before you fly. The setup needs an internet connection, while airport wifi can be slow or require a login you cannot complete yet. Once the Atli profile is on your iPhone, leave it installed and switch it on for data when you arrive.

Does my iPhone support eSIM?

Most iPhones from the XS and XR onward support eSIM, but the exact model and where it was purchased matter. Apple currently lists only iPhone Air and iPhone 17e as eSIM-capable in China mainland. Two quick checks:

How to install an eSIM on Android

Install your eSIM at home on reliable wifi before you fly. Android menu names vary by manufacturer: Samsung uses SIM manager, while Pixel uses SIMs. If your phone uses different wording, search Settings for “eSIM” or “SIM.” Once the Atli profile is installed, leave it on the phone and switch it on for data when you arrive.

Does my Android support eSIM?

Support depends on the exact model, sales region, and carrier lock. Google says every Pixel 4 and later supports eSIM, while Pixel 3 and 3a have regional and carrier exceptions. Samsung support also varies between regional versions of the same Galaxy model. Dial *#06#; an EID indicates that the phone has eSIM hardware. Then check that your exact phone supports eSIM and is unlocked.
