Refurbished iPhone 18 Pro Max

An unlocked refurbished iPhone works with any carrier that supports its network bands, so it is the safe choice when you are unsure. A carrier-locked iPhone only works on the network it was tied to. RefurbMe shows each listing's carrier and lets you filter to unlocked models, so you can match a phone to your network before you buy.

RefurbMe lists iPhones locked to major US networks, including:

• AT&T
• T-Mobile
• Sprint
• Verizon
• Tracfone
• Cricket
• Xfinity Mobile

You will find these under the Carrier filter. Smaller carriers, such as Mint Mobile, usually run on one of these host networks, so an unlocked phone works fine. Check with your carrier if you are not certain.

Pick an unlocked iPhone. Unlocked and SIM-free phones accept any compatible SIM, so they work across networks and when you travel abroad. You can also unlock a locked iPhone if it meets the carrier's conditions.

Two things matter: the lock status and the network bands. An unlocked iPhone bought for your region will support your local carriers, and recent models (iPhone X and later) handle every major US network technology, so band mismatches are rare on phones sourced in-country. For a specific unit, an IMEI check with your carrier confirms it is compatible and not blacklisted.

For the wider picture, see unlocked vs SIM-free and which SIM card fits.

Some refurbished phones are locked to a single carrier, and some are sold unlocked. A carrier-locked iPhone only works with SIMs from the network it was tied to, while an unlocked one works on any compatible carrier. On RefurbMe you can see the status before you buy, because every iPhone listing shows its carrier and you can filter to unlocked models only.

Every iPhone listing on RefurbMe shows a carrier value. If it names a network, such as AT&T or Verizon, the phone is locked to that network. If it says Unlocked, it works with any compatible carrier.

When you are unsure about a specific unit, an IMEI check with your carrier confirms the lock status.

Scroll down to Carrier and select the option(s) you want, including Unlocked:

Unlocked phones suit you if your carrier is not on the list, or if you might switch networks later. You can also unlock a locked iPhone once it meets the carrier's conditions.

Locked models are sometimes a little cheaper, but they tie you to one network. Unlocked, or SIM-free, is the flexible choice and travels better. The difference between the two is explained in unlocked vs SIM-free, and you can check first whether a phone is compatible with your carrier.

Yes. Refurbished iPhones support eSIM if the original model includes eSIM hardware. The refurbishment process does not affect eSIM capability. Any iPhone XS or later supports eSIM, and all iPhone 17 models and iPhone Air are eSIM-only worldwide (no physical SIM tray).

eSIM support was introduced with the iPhone XS lineup in 2018:

• eSIM + physical SIM: iPhone XS, XR, 11, 12, 13 (all variants), iPhone 16e, and iPhone SE (2nd and 3rd generation). Also iPhone 14, 15, and 16 in markets outside the US.
• eSIM-only (no SIM tray): iPhone 14 and later sold in the United States. All iPhone 17 models (17, Air, Pro, Pro Max) are eSIM-only worldwide regardless of market.
• No eSIM: iPhone X and older models.

eSIM is a digital SIM that is built into the phone. Instead of inserting a physical SIM card, you activate a carrier plan by scanning a QR code or using your carrier's app. You can store multiple eSIM profiles, making it easy to switch carriers or use separate plans for personal and work lines.

No. The previous owner's eSIM profile is removed during the refurbishment process, along with all other user data. When you set up your refurbished iPhone, you can activate your own eSIM through your carrier. Contact your carrier or check their website for eSIM activation instructions.

Most major carriers support eSIM, but availability varies. Check with your carrier before purchasing if eSIM support is important to you. If your carrier does not support eSIM, make sure the refurbished iPhone model you are buying has a physical SIM tray.

Not every refurbished iPhone gets a new battery, but Apple Certified Refurbished iPhones always do. Apple states that every unit it refurbishes receives a brand-new battery and outer shell. Third-party refurbishers instead test the existing battery and replace it only if it falls below their standard. Whether the battery is new depends on who refurbished the phone.

Yes. Apple confirms that every Apple Certified Refurbished iPhone ships with a brand-new battery and outer shell. This is one of the strongest reasons to choose Apple refurbished stock over cheaper alternatives. To see only these units on RefurbMe, filter by Apple Store listings.

Independent refurbishers such as Back Market, Amazon Renewed, and others usually guarantee a minimum battery health rather than a new cell. During refurbishment the iPhone is fully tested, and if the battery fails that test it is replaced. If it passes, the phone keeps its original battery, which is why you should check the health figure or guarantee on each listing.

For the health levels to expect, see what battery health do refurbished iPhones have?

• Open Settings > Battery > Battery Health & Charging.
• Read the Maximum Capacity figure. A new battery shows 100%, and Apple considers anything at 80% or above to be healthy.
• If Peak Performance Capability shows a warning, the battery may need replacing.

If your refurbished iPhone arrives with unexpectedly low battery health, act within the return window:

• Contact the seller first, since most offer a return or exchange.
• Check whether your warranty covers battery issues.
• Next time, compare battery guarantees across refurbishers before you buy.

No. A refurbished iPhone from a professional refurbisher should never have an activation lock. Reputable sellers remove iCloud Activation Lock and erase all previous user data as a standard part of the refurbishment process.

Activation Lock is an Apple security feature tied to iCloud. When enabled, the iPhone cannot be set up or used without the original owner's Apple ID and password. It is designed to protect against theft, but it can also prevent a new owner from using a legitimately purchased device if it was not properly removed before resale.

All refurbishers listed on RefurbMe are vetted professionals who follow proper procedures to remove Activation Lock before listing any device. This is one of the key differences between buying from a certified refurbisher and buying from an individual seller on a marketplace.

If you buy a refurbished iPhone and encounter an Activation Lock screen during setup, contact the seller immediately. This should be covered under the seller's warranty and return policy.

When you receive your iPhone, you will know during the initial setup process whether Activation Lock is present. If the phone asks for a previous owner's Apple ID, it has not been properly cleared. For extra peace of mind, you can read our guide on what a locked phone means and how to handle it.

Yes, refurbished iPhones support 5G if the original model includes 5G hardware. The refurbishment process does not remove or disable 5G capability. Any iPhone 12 or later will connect to 5G networks just like a brand-new unit.

5G support was introduced with the iPhone 12 lineup in 2020. The following models and all later generations support 5G:

• iPhone 12 / 12 mini / 12 Pro / 12 Pro Max
• iPhone 13 / 13 mini / 13 Pro / 13 Pro Max
• iPhone 14 / 14 Plus / 14 Pro / 14 Pro Max
• iPhone 15 / 15 Plus / 15 Pro / 15 Pro Max
• iPhone 16 / 16 Plus / 16 Pro / 16 Pro Max
• iPhone 16e
• iPhone 17 / iPhone Air / 17 Pro / 17 Pro Max
• iPhone SE (3rd generation)

Any iPhone model older than the iPhone 12 (such as iPhone 11, XS, or XR) does not support 5G, regardless of whether it is new or refurbished.

On RefurbMe, you can use the Features filter to select 5G-compatible models. You can also browse specific model pages directly, since any iPhone 12 or newer will have 5G built in.

A 5G-capable iPhone will still work on 4G LTE networks if your carrier plan does not include 5G. You do not need to upgrade your plan to use a refurbished 5G iPhone, but you will only get 5G speeds if your carrier and plan support it.
