The phone with no tray
Apple introduced the iPhone 15 Pro Max in 2023 in 256 GB, 512 GB and 1 TB, in four titanium finishes. Apple's "Identify your iPhone model" page (read 10 November 2026) makes one point that changes how you check it: "In the United States, there's no SIM tray." Elsewhere it has a tray on the left side holding a nano-SIM.
That matters for two reasons. First, the IMEI you would normally read from the tray is not there on a US phone, so every route to it goes through software or the box. Second, the quick buyer's test of putting your own SIM in does not exist. You can only check the lock with the phone's own Settings screen or with the IMEI.
| A-number | Sold in | Checked on FullIMEI (90 days) |
|---|---|---|
| A2849 | United States, Puerto Rico | 333 devices |
| A3106 | Other countries and regions | 21 devices |
| A3105 | Canada, Guam, Japan, Mexico, Saudi Arabia, US Virgin Islands | 14 devices |
| A3108 | Mainland China, Hong Kong, Macao | under 10 |
Four ways to read the number without a tray
- Settings, General, About. The IMEI is listed there. This is the one to trust, because it is read from the phone, not from a sticker.
- Dial *#06# in the Phone app. It prints the number straight from the phone, so do it with the seller in the room.
- The retail box. The label prints the IMEI. If the box number does not match the screen, the box belongs to another phone and you should say so.
- Apple Account, Devices. If the phone is signed in, the account's device list shows it. If it is still signed in under someone else's name, Activation Lock may be on.
The long version, with screenshots of each route, is in Find the IMEI on an iPhone.
What the US-build checks looked like
Of the 333 A2849 phones, the lookup read a lock on 107: 73 as locked and 34 as unlocked. That puts unlocked at about one in ten of everything checked, against fewer than one in twenty for the iPhone 13 over the same period. The other 226 returned unknown for the usual reason: the free check only reads T-Mobile and Metro locks.
| A2849 result | Devices | Share of 333 |
|---|---|---|
| Locked to a carrier we read | 73 | 22 % |
| Unlocked | 34 | 10 % |
| Unknown (lock not readable for free) | 226 | 68 % |
Where the checks were made: 130 in Pakistan, 87 in the United States, 14 in Nigeria and 10 in Mexico. As with other US-built iPhones, a large share of checking happens outside the United States, which is where an eSIM-only, carrier-tied phone is most likely to arrive as a surprise.
Buying one: what to ask for
The iPhone 15 Pro Max usually sells at a price that tempts a seller to hide a balance. Ask for a screenshot of Settings, General, About showing the Carrier Lock line and the IMEI together, and for the payoff status from the carrier if the phone was on a plan. Then run the number above and keep the result. The blacklist side of that check is covered on the blacklist page, and the rules for how a locked phone becomes unlocked are on the unlock page.
Counts are different phones over 12 August to 10 November 2026, one IMEI once. Rows under ten are hidden. They will change with the next update.
Questions people ask
How do I find the IMEI on a US iPhone 15 Pro Max if there is no SIM tray?
Apple says the US model has no SIM tray at all, so there is nothing to read the number from by hand. Use Settings, General, About, or dial *#06#. The retail box label also prints it, and if the phone is signed in to an Apple Account, the Devices list on that account shows it.
What are the model numbers for the iPhone 15 Pro Max?
Apple lists A2849 for the United States and Puerto Rico, A3105 for Canada, Guam, Japan, Mexico, Saudi Arabia and the US Virgin Islands, A3108 for mainland China, Hong Kong and Macao, and A3106 for other countries and regions.
Why is a lock harder to spot on an eSIM-only phone?
With no tray there is no quick swap test. On a tray phone you can drop in another carrier's SIM and see if it connects. On an eSIM-only phone, you have to read the Carrier Lock line in Settings, General, About, or run the IMEI, because an eSIM profile can only be tried once the seller has handed the phone over.
Does the free check show if a 15 Pro Max is locked?
It reads locks tied to T-Mobile and Metro. For any other carrier the answer is unknown. Out of 333 US-build units checked in the last 90 days, 107 returned a locked or unlocked reading and 226 did not.
Is a titanium iPhone 15 Pro Max safe to buy because it is newer?
Newer does not mean paid off. A 15 Pro Max is often sold on a monthly plan, and some carriers keep it locked until the last payment. Ask for a screenshot of the Carrier Lock line and the payoff status before paying.
Does a 15 Pro Max from another country work on a US network?
Often yes for the radio, but the lock rules and the eSIM-only design of the US model mean you should confirm that a profile can be installed. Run the IMEI first, then open the compatibility check for the carrier you plan to use.
