Does the iPhone 15 Pro support eSIM?

The iPhone 15 Pro is what decides whether a travel eSIM installs, not the Apple name on the box. Storage, radio and market variant all change from one model to the next, so every figure below was checked on this model.

Yes. The iPhone 15 Pro stores up to 8 eSIM profiles and can keep 2 active at the same time. Installing a travel eSIM takes about 40 seconds and does not touch your normal SIM.

Worth knowing about this modelUnited States models are eSIM only and have no SIM tray. Models sold elsewhere keep the tray.

What the iPhone 15 Pro does with a travel eSIM

The iPhone 15 Pro is a phone, so the travel profile is a data line and your existing line stays the voice line. Calls and texts to your usual number keep arriving while Orbislo carries the browsing.

Installing writes the profile. Nothing is spent until it attaches to a network at the destination, so an install three weeks early costs exactly the same as one at the gate. Do it at home, on wifi, while you still have a connection to fix anything.

Storage and active lines

The iPhone 15 Pro holds 8 profiles, which is enough that most people never reach the limit. It still fills up if a provider issues a fresh disposable eSIM for every trip.

Active is how many lines run at the same time, and on the iPhone 15 Pro that is 2. Storage is how many profiles sit on the device waiting, and that is the number that runs out without warning.

Each destination's line installs in one tap from the Orbislo app, and while it is valid every refill lands on that same line. Most of Europe runs on a single line, so a trip through several neighbouring countries takes one slot rather than one per country.

Home line: calls and texts, so bank codes still arrive on your usual number.
Orbislo line: mobile data, with roaming switched on.
Automatic data switching: off, or the phone borrows the expensive line in a tunnel.

5G on the iPhone 15 Pro, and where it will not appear

The iPhone 15 Pro has a 5G radio and the travel profile uses it. Where a partner network runs 5G, you get 5G, on the same profile and at no extra cost.

88 of our 197 destinations are 4G only on the networks we buy from. On those the icon reads LTE whatever the handset can do, and no setting changes it.

Speed belongs to the network rather than to the profile.

What goes wrong on the iPhone 15 Pro, and the fix

Data roaming has to be switched on for this line. Your profile is issued outside the country you are standing in, so the device treats every attachment as roaming. Leave it off and the iPhone 15 Pro finds a network and then refuses to use it.

If the profile will not download at all, the order refunds automatically inside 60 seconds, with no ticket. Install again from the same order, because the profile is reissued to your account rather than lost.

On this device the sequence is Settings, Cellular, tap the Orbislo line, turn on Data Roaming. Then Settings, Cellular, Cellular Data, choose Orbislo, and turn off Allow Cellular Data Switching.

No service on the Orbislo line: roaming is off on that line.
Connected but nothing loads: mobile data still points at the home line.
Works, then stops after an hour: automatic data switching moved you back.
Still searching: airplane mode on for 20 seconds, off, then restart.

Your SIM tray, and tethering

Tethering is included on every Orbislo plan at no extra charge. The iPhone 15 Pro can share the travel data with a laptop, a tablet or a watch, and nothing behind the hotspot needs a profile of its own.

What an Orbislo plan does once it is installed

Data never expires. A gigabyte you do not use in Lisbon is still there in Bangkok next year, metered plans have no throttle, and every customer gets 100 MB of free rescue data once a month on the line in use when the balance runs out. Unlimited runs full speed to 2 GB a day and then 1 Mbps.

One balance pays in all 197 destinations, and most of Europe runs on a single line, so a rail trip through three neighbouring countries is one install and one balance rather than three of each. Refills arrive on the line you already have, with no new plan or expiry date. Where a destination has more than one partner network, the line can move between them without you touching a setting.

How to install a travel eSIM on the iPhone 15 Pro

Open the Orbislo app and tap Install
Confirm in the Add Cellular Plan sheet iOS shows you
Leave the label as Orbislo
Turn on Data Roaming for the Orbislo line

Data roaming sounds like it will cost you money. On the Orbislo line it cannot, because it is how that line reaches partner networks abroad and there is no charge beyond the data you already bought.

iPhone 15 Pro eSIM questions

Does the iPhone 15 Pro support eSIM?

Yes. It stores 8 profiles and runs 2 at the same time. Installing an Orbislo profile takes about 40 seconds and does not touch the SIM you already have.

How many eSIMs can the iPhone 15 Pro hold?

8 stored, 2 active at once. Storage is the number that runs out, because a provider that issues a new profile for every trip fills it in a few holidays.

Will I lose my own number?

No. Keep the home line as the voice line and point mobile data at Orbislo. Calls and texts keep arriving on your usual number, as long as your home carrier delivers them abroad.

Do I have to turn roaming on?

Yes, on the Orbislo line only, and it cannot cost you anything. The profile is issued outside the country you are in, so every attachment counts as roaming.

Can I install before I fly?

Yes, and you should. The plan starts counting when the profile first attaches to a network abroad, so an install three weeks early costs the same as one at the gate.

Does tethering work on the iPhone 15 Pro?

Yes, on every plan and at no extra charge. Share the travel data from the hotspot with a laptop, a tablet or a watch. Nothing behind it needs a profile of its own.

Pick the destination, then install its line in one tap

Take the metered wallet for maps and messaging, because the balance never expires. Take unlimited if you tether a laptop or stream, and read the 2 GB a day figure before you do.

The iPhone 15 Pro by market

United States and Puerto Rico (A2848): Apple sells the iPhone 15 Pro in the United States and Puerto Rico as model A2848, built without a SIM tray. Every line on it, including a travel eSIM, has to be an eSIM, and physical SIM cards from abroad cannot be inserted.
Canada, Japan, Mexico, Saudi Arabia, Guam and the U.S. Virgin Islands (A3101): Buyers in Canada, Japan, Mexico, Saudi Arabia, Guam and the U.S. Virgin Islands get model A3101. This iPhone 15 Pro has a nano-SIM tray on the left edge, letting a home SIM card stay in place beside a travel eSIM.
Other countries and regions, including the United Kingdom and Europe (A3102): In the United Kingdom the iPhone 15 Pro carries model number A3102 and supports Dual SIM with a nano-SIM and an eSIM, as well as Dual eSIM. Travellers can pair a travel eSIM with either kind of home line.
China mainland, Hong Kong and Macao (A3104): The iPhone 15 Pro listed on Apple's Hong Kong site is model A3104, with two nano-SIM card slots and no eSIM. Owners of this version cannot add a travel eSIM and need a local SIM card when they travel.

Networks on the iPhone 15 Pro

The iPhone 15 Pro model A2848 for the United States lists both sub-6 GHz and mmWave 5G, with mmWave on bands n258, n260 and n261. Its LTE list runs from band 1 to band 71 but leaves out bands 11 and 21.
Model A3102, the iPhone 15 Pro for the United Kingdom, supports sub-6 GHz 5G on bands such as n1, n3, n7, n20, n28, n77 and n78. It does not list 5G bands n14, n29 or n71, or LTE bands 14, 29 or 71, and it has no mmWave.
The Japanese iPhone 15 Pro, model A3101, lists LTE bands 11 and 21 on top of the usual LTE set, and its 5G bands include n14, n29, n71, n77, n78 and n79. It connects over sub-6 GHz 5G, without mmWave.
Model A3104 from Hong Kong lists no 5G band n53 and no TD-LTE band 53, and it also omits n14, n29 and n71. Its 5G still covers n1, n3, n7, n28, n41, n77 and n78, on sub-6 GHz only.
Voice over LTE and Wi-Fi calling are both supported on the iPhone 15 Pro, and it keeps two eSIMs active at once from a store of eight or more. A traveller can leave a home eSIM on for texts while a travel eSIM runs data.
If you choose Travel eSIM and Current eSIM on an iPhone 15 Pro, the travel eSIM is used for data, but the home line can still pick up roaming fees. Choosing the travel eSIM alone keeps FaceTime and iMessage working on your home number.
With no mobile or Wi-Fi signal, the iPhone 15 Pro can text emergency services by satellite in the United States, Canada, Mexico, Japan, Australia, New Zealand, the United Kingdom, Ireland, Switzerland, Iceland and ten other European countries including France, Germany, Italy and Spain.
An iPhone 15 Pro bought in China mainland, Hong Kong or Macao has no satellite connectivity, and neither does one bought in Armenia, Belarus, Kazakhstan, Kyrgyzstan or Russia. Elsewhere Apple includes its satellite features free for two years from activation, where the country or region supports them.
Messages via satellite on the iPhone 15 Pro works in the United States, Canada, Mexico and Japan and needs iOS 18, or iOS 18.4 in Mexico. Photos, videos, audio messages and group chats cannot be sent over the satellite link.

Worth knowing about the iPhone 15 Pro

Travel eSIMs from another provider only work on an iPhone 15 Pro that is not carrier locked. An unlocked phone shows No SIM Restrictions beside Carrier Lock under Settings, General, About. Apple cannot remove a lock; only the carrier that sold the phone can.
Apple warns that an eSIM plan on the iPhone 15 Pro can include limits on roaming and on switching providers, even after the contract ends, so a phone bought through a carrier is worth checking before a trip.
Apple counts the iPhone 15 Pro among its eSIM models, but not for units sold in Hong Kong, Macao or China mainland, where only other iPhone models are listed as supporting eSIM.
On iOS 26 and later, the iPhone 15 Pro may ask whether a newly bought eSIM is for home or for travel, and on arrival a Turn On Travel eSIM notice lets you switch it on and decide whether to use Low Data Mode.
An iPhone 15 Pro can take over a phone number from an older iPhone through eSIM Quick Transfer when both run iOS 18.4 or later. With iOS 26, several numbers can move across in a single transfer.
Some carriers send a setup link or a QR code by email instead of a card. On an iPhone 15 Pro with iOS 17.4 or later, tap the link, or press and hold the QR code and tap Add eSIM.
Carriers including AT&T, T-Mobile and Verizon in the United States, Bell and Telus in Canada, and Orange in France support moving an eSIM from an Android phone to an iPhone 15 Pro running iOS 26 or later.
iOS 27 supports the iPhone 15 Pro, which appears on Apple's list of compatible iPhone models for that release.
