Yes. The Hong Kong and Australian iPhone 18 Pro and iPhone 18 Pro Max keep the nano-SIM tray, so a China mainland SIM card goes in the tray while a travel eSIM runs alongside it. Apple’s Hong Kong and Australian spec pages both list the SIM line as a nano-SIM plus an eSIM, with dual eSIM support as well. The US version has no tray at all.
Two things make this the setup mainland travellers ask about. Apple says an iPhone bought outside China mainland cannot install an eSIM from a mainland carrier, so a physical SIM is the only way to hold a mainland number on a Hong Kong or Australian phone. And Apple lists the same cellular bands for that version as for the mainland version. One warning before you shop: iPhone Duo and iPhone Air are eSIM-only in Hong Kong and Australia too.
- Hong Kong and Australia, iPhone 18 Pro / Pro Max: models A3714 and A3717, nano-SIM plus eSIM.
- Same model, 190 countries: the Hong Kong, Macao, Australian and UK versions are the same A-numbers.
- Mainland carrier eSIM: not available on a phone bought outside China mainland, per Apple.
- Bands: Apple lists every band the mainland version lists, plus one more.
- No tray: iPhone Duo, iPhone Air and every US iPhone 18 Pro.
Which version has a SIM tray
We read the SIM Card line on Apple’s own spec pages for each store on 19 September 2026. The wording is Apple’s; the last column is what it means for a mainland China SIM card.
| Version | Model numbers | SIM line on Apple’s spec page | Takes a China SIM card? |
|---|---|---|---|
| iPhone 18 Pro / Pro Max, Hong Kong | A3714 / A3717 | Dual SIM (nano-SIM and eSIM); dual eSIM support | Yes, in the tray |
| iPhone 18 Pro / Pro Max, Australia | A3714 / A3717 | Dual SIM (nano-SIM and eSIM); dual eSIM support | Yes, in the tray |
| iPhone 18 Pro / Pro Max, China mainland | A3715 / A3718 | Two nano-SIM cards, or one nano-SIM and one eSIM, or two eSIMs | Yes, two of them |
| iPhone 18 Pro / Pro Max, United States | A3472 / A3473 | Dual eSIM; “not compatible with physical SIM cards” | No |
| iPhone Duo, Hong Kong and Australia | A3720 | Dual eSIM; not compatible with physical SIM cards | No |
| iPhone Air, Hong Kong and Australia | A3517 | Dual eSIM; not compatible with physical SIM cards | No |
| iPhone 17, Hong Kong and Australia | A3520 | Dual SIM (nano-SIM and eSIM); dual eSIM support | Yes, in the tray |
The Hong Kong and Australian units are not two different phones. Apple’s cellular page puts Hong Kong, Macao, Australia and the UK in the same block: iPhone 18 Pro model A3714 and iPhone 18 Pro Max model A3717, sold in 190 countries and regions. Buying in Hong Kong or in Sydney gets you the same hardware. Our guide to iPhone 18 Pro model numbers by country lists the rest, and the SIM tray by country guide covers every store we checked.
Why a mainland number means a physical SIM here
Apple published a support article on 9 September 2026 listing the iPhone models that support eSIM in China mainland: iPhone 18 Pro model A3715, iPhone 18 Pro Max model A3718, iPhone Duo model A3721, iPhone 17e model A3635 and iPhone Air model A3518. All of them are the mainland versions. The article then says other models, “including those purchased outside of China mainland, are unable to install an eSIM profile from carriers in China mainland”.
So on a Hong Kong or Australian iPhone 18 Pro, a China Mobile, China Telecom or China Unicom line has to be a nano-SIM in the tray. That is not a workaround; it is the configuration Apple sells that phone with. Apple’s travel page puts the other half plainly: “If your iPhone has a SIM tray, you can use both a physical SIM and an eSIM while traveling internationally.”
Two practical notes. Mainland carriers register a SIM to an identity document, and Apple tells customers activating eSIM at a mainland carrier store to bring a government ID or passport, so plan for ID checks either way and ask the carrier what a visitor needs. And Apple notes that dual VoLTE is supported by some carriers only, so check with both carriers if you want HD voice on both lines at once.
Does the Hong Kong version get mainland 5G?
Apple lists the supported bands per model number on its cellular page. We compared the Hong Kong and Australian block with the China mainland block, as read on 15 September 2026.
| Bands Apple lists | Hong Kong / Australia (A3714, A3717) | China mainland (A3715, A3718) |
|---|---|---|
| 5G bands | 23, including n1, n3, n5, n8, n28, n41, n78 and n79 | 22, the same list without n53 |
| LTE bands | 28, including 1, 3, 5, 8, 34, 38, 39, 40 and 41 | 27, the same list without 53 |
| Bands the other version has that this one does not | None | n53 and LTE band 53 |
In other words, the Hong Kong and Australian version supports every band Apple lists for the mainland version, and adds n53 and LTE band 53 on top. The bands mainland networks are built on — n41, n78 and n79 for 5G, and LTE 1, 3, 5, 8, 38, 39, 40 and 41 — are all on the list.
Bands are what the phone supports, not a promise of service. What you actually get depends on the carrier, the plan, the local site and how the network is configured, and Apple’s list does not speak to that. We have not run drive tests in China.
Running a China SIM and a travel eSIM together
With the mainland SIM in the tray and a travel eSIM installed, the iPhone treats them as two lines. Apple’s dual SIM guide explains the settings: label the two plans, pick a default number, and choose which line carries cellular data. Both numbers can take calls and iMessages, but, as Apple puts it, your iPhone “can use one cellular data network at a time”.
| What you want | Hong Kong or Australian 18 Pro | China mainland 18 Pro | US 18 Pro |
|---|---|---|---|
| Mainland carrier nano-SIM | Yes, one tray | Yes, the tray takes two | No tray |
| Mainland carrier eSIM | No, per Apple | Yes, in a carrier store with an ID check | No |
| Travel eSIM from a worldwide provider | Yes | Apple says not while in China mainland | Yes |
| Two lines at once | nano-SIM + eSIM, or two eSIMs | Two nano-SIMs, nano-SIM + eSIM, or two eSIMs | Two eSIMs |
The third row is the one people miss. Apple’s mainland article says a mainland-bought iPhone can activate a local carrier’s eSIM when you travel outside China mainland, with Location Services on, and that “eSIMs from non-China mainland carriers can’t be installed while located in China mainland”. A Hong Kong or Australian phone carries no such restriction, which is why it is the flexible one for someone who crosses the border often.
Whichever version you have, install a travel eSIM before you fly. Activation needs a working internet connection, and the moment you want it most is the moment you step off the plane with no data. Our China travel eSIM guide walks through the order, and the dual SIM guide covers keeping your home number reachable.
Heading to China with a Hong Kong or Australian iPhone? Apple’s own travel page notes that visitors to China mainland can use a prepaid data eSIM from a worldwide provider. Browse our China eSIM plans, or pick up Hong Kong, Australia or any of 190+ destinations for the rest of the trip.
Before you buy the phone
- Check the A-number, not the name. Settings, General, About, then tap the part number to see the model. A3714 or A3717 is the Hong Kong, Macao, Australian and UK version of iPhone 18 Pro and Pro Max.
- Check it is not carrier-locked. A phone locked to a Hong Kong or Australian carrier may refuse another carrier’s SIM. Ask the seller before paying, especially for a contract unit.
- Do not buy Duo or Air for this. Both are eSIM-only in every store we checked, so there is no tray for a mainland SIM.
- Decide what you need two of. If you want two mainland numbers in one phone, that is the mainland version’s dual tray. If you want a mainland number plus flexible travel data, the Hong Kong or Australian version is the one.
- Prices differ by store. Our iPhone 18 Pro price comparison converts Apple’s own prices, and buying an iPhone abroad covers warranty and tax.
Travel eSIMs that sit alongside a mainland SIM
The setup above — mainland SIM in the tray for calls and verification codes, travel eSIM for data — works with any of these. Pick by destination; the China SIM stays where it is. All of them start counting on first use at your destination — first data use or first network connection, depending on the plan — rather than at purchase. Prices are from our catalogue on 23 September 2026 and move daily.
| Destination | Plan | Price |
|---|---|---|
| Japan | 10 GB / 15 days | $7.40 |
| South Korea | 10 GB / 15 days | $6.20 |
| Thailand | 10 GB / 30 days | $7.00 |
| Hong Kong | 10 GB / 30 days | $7.00 |
| Europe | 10 GB / 30 days | $7.54 |
One setting to check before you leave: turn data roaming off on the mainland line and make sure the phone cannot fall back to it for data, or it can run up roaming charges while the travel eSIM sits unused. The four settings involved are in can a travel eSIM trigger roaming charges on your main line.

SIM configurations are quoted from Apple’s iPhone 18 Pro, iPhone Duo, iPhone Air and iPhone 17 spec pages on the Hong Kong, Australian, US and China mainland stores, read on 19 September 2026. Model numbers and bands come from Apple’s cellular page, read on 15 September 2026. The mainland eSIM rules are from Apple’s support articles on using eSIM in China mainland, published 9 September 2026, and travelling with eSIM; dual SIM behaviour is from Apple’s Dual SIM with an eSIM guide.
One inconsistency worth knowing: Apple’s travel page lists four models as supporting eSIM in China mainland, while the dedicated mainland article lists five, adding iPhone Duo. We follow the dedicated article, which carries the later date. Apple can change availability at any time, and carriers set their own rules on top.
Frequently asked questions
Can a Hong Kong iPhone 18 Pro use a China Mobile SIM card?
Yes. Apple’s Hong Kong spec page lists the iPhone 18 Pro SIM line as a nano-SIM plus an eSIM, so a mainland carrier’s nano-SIM goes in the tray. Apple also lists every band for this model that it lists for the China mainland model.
Does the Australian iPhone 18 Pro have a SIM tray?
Yes. Apple’s Australian spec page lists Dual SIM with a nano-SIM and an eSIM, plus dual eSIM support. The Australian and Hong Kong units are the same model numbers, A3714 for iPhone 18 Pro and A3717 for iPhone 18 Pro Max.
Can I install a China mainland carrier eSIM on a Hong Kong iPhone?
No. Apple’s support article on eSIM in China mainland says models other than the five mainland versions it lists, including iPhones purchased outside China mainland, cannot install an eSIM profile from mainland carriers. Use a physical nano-SIM for a mainland number instead.
Can I use a China SIM card and a travel eSIM at the same time?
Yes, on a version with a tray. Apple says that if your iPhone has a SIM tray you can use a physical SIM and an eSIM together while travelling. You choose which line carries cellular data, and only one data network is active at a time.
Do Hong Kong and Australian iPhones support mainland 5G bands?
Apple lists 23 5G bands for model A3714 and A3717, including n1, n41, n78 and n79, which covers every band listed for the mainland model. Band support is not a service guarantee: coverage still depends on your carrier, plan and location.
Can iPhone Duo or iPhone Air take a China SIM card?
No. Apple lists both as dual eSIM devices that are not compatible with physical SIM cards, and that is true on the Hong Kong and Australian stores as well. If you need a mainland nano-SIM, choose iPhone 18 Pro, iPhone 18 Pro Max or iPhone 17.
Which model number is the Hong Kong iPhone 18 Pro?
A3714 for iPhone 18 Pro and A3717 for iPhone 18 Pro Max. Apple’s cellular page sells that block in 190 countries and regions, including Hong Kong, Macao, Australia and the UK. Check yours in Settings, General, About, then tap the part number.
Should I install a travel eSIM before flying to China?
Yes. Installing an eSIM needs an internet connection, so set it up on Wi-Fi at home and switch it on after you land. A mainland-bought iPhone has a further limit: Apple says non-mainland eSIMs cannot be installed while the phone is in China mainland.
Bottom line
For anyone who needs a mainland China number and flexible travel data in one phone, the Hong Kong or Australian iPhone 18 Pro and Pro Max are the straightforward choice: model A3714 or A3717, a nano-SIM tray for the mainland line, an eSIM slot for everything else, and the mainland version’s full band list. Skip iPhone Duo and iPhone Air if the tray matters, skip the US version entirely, and set up the travel eSIM before you leave.
