Apple sells iPhone 18 Pro with a “Connect on your own later” option, and the $1,199 to $2,399 prices on its Store page are the prices for that unattached configuration. Picking a carrier in the same checkout does not change what you pay Apple. It changes what you are committed to afterwards.
What nobody has published is the part most buyers want: whether a carrier-bought iPhone 18 Pro ships locked, and for how long. AT&T and Verizon have posted no iPhone 18 Pro terms at all, and T-Mobile’s site blocked our access, so anything attributed to it is unconfirmed. Here is what is actually on the record.
| Key fact | What is published, and by whom |
|---|---|
| Unattached price | $1,199 for 256GB with “Connect on your own later” (Apple’s Store page) |
| Apple financing rule | Buying an iPhone with Apple Card Monthly Installments requires AT&T, T-Mobile or Verizon, and prepaid plans are not supported (Apple) |
| Connectivity discount | $30, named by Apple only for iPhone 17 and iPhone 16, and requires carrier activation |
| On the new phones | No connectivity discount published for iPhone 18 Pro, iPhone 18 Pro Max or iPhone Duo |
| SIM hardware | eSIM only, with no SIM tray, in the US and 11 other markets (Apple) |
| Lines supported | Dual eSIM, two active, stores eight or more (Apple’s tech specs) |
| Carrier locking terms | Not published by any US carrier for iPhone 18 Pro |
The unattached option is on Apple’s own page
Apple’s iPhone 18 Pro Store page prices the phone at $1,199 for 256GB, $1,399 for 512GB, $1,799 for 1TB and $2,399 for 2TB, read from the configuration that connects later. The Pro Max runs $1,299 to $2,499. Paying those figures outright is the version of this purchase with no plan, no term and no credit attached to it.

That matters more this year than usual, because there is no carrier-linked price cut on these models to weigh against it. Apple names a $30 connectivity discount that requires carrier activation, but it names it for iPhone 17 and iPhone 16 only. On the new Pro models the attached and unattached prices are the same number.
What choosing a carrier at checkout commits you to
Apple’s own financing terms are the clearest published constraint. Apple states that in order to buy an iPhone with Apple Card Monthly Installments, you must select AT&T, T-Mobile or Verizon, and that prepaid carrier plans are not supported. So the 24 month, 0 percent route at $49.95 a month for the iPhone 18 Pro is closed to anyone who wants to connect later or runs a prepaid line.
The carrier credits carry their own commitment. Apple’s Store page describes them as monthly bill credits over 36 months on a qualifying plan, with amounts varying by plan tier and customer type. Three years is a long time to owe a network your loyalty in exchange for money you have not been paid yet.
The three routes, side by side
| Route | What Apple charges | Apple Card Monthly Installments | Carrier credit |
|---|---|---|---|
| Unattached, connect later | $1,199 for 256GB | Not available on this route | None |
| Carrier picked inside Apple’s checkout | $1,199 for 256GB | AT&T, T-Mobile or Verizon postpaid only | Up to $1,200 over 36 months, per Apple’s footnotes |
| Bought from a carrier directly | AT&T lists $33.34 a month on its own page | Carrier’s own agreement | No terms published by any carrier |
What actually changes when you travel
The hardware answer is the same whichever route you take. iPhone 18 Pro is eSIM only, with no SIM tray, in Bahrain, Canada, Guam, Japan, Kuwait, Mexico, Oman, Qatar, Saudi Arabia, the UAE, the United States and the US Virgin Islands. A US phone therefore cannot take a local plastic SIM abroad, whatever its locking status. A local line has to be an eSIM.
Apple’s tech specs list dual eSIM with two lines active at once and storage for eight or more profiles, which is the feature that makes a travel line practical: home number receiving calls, local data plan carrying the traffic. What a carrier lock would restrict is whose eSIM you may add, and that is precisely the term none of them has published for this phone.
What has not been confirmed
- No US carrier has published locking or unlocking terms for iPhone 18 Pro. Reports that T-Mobile ships iPhones locked, with 36 month financing, could not be verified because its site blocked our access.
- Verizon has published only that pre-orders begin 9/12 at 8 a.m. EDT. AT&T’s deals page still leads with iPhone 17 Pro Max.
- Apple has published no connectivity discount for iPhone 18 Pro, iPhone 18 Pro Max or iPhone Duo.
- Boost is a carrier option in Apple’s checkout, but no Boost terms have been published.
Pre-orders open at 5 a.m. PT on Saturday, September 12, with phones arriving Friday, September 18. If you travel often, or expect to switch networks inside three years, the unattached configuration is the one whose terms you can actually read today.
