The quickest way to verify your iPhone model is to locate it in your phone’s settings menu.

Go to Settings > General > About > Model Name

You can also identify your model number and cross reference that number on Apple’s website.

Go to Settings > General > About. To the right of Model Number, you'll find the part number. To find the model number, tap the part number.

Next, check your model number on Apple's site.

If your iPhone does not power on and has a SIM tray, you can locate the model number removing the SIM tray and looking in the slot. The model number is on the upper side near the display.

iPhone models that support only eSIM don't have a SIM tray. To find the model number for models without a SIM tray, look in the Lightning or USB-C connector. You'll find the model number on the upper side of the connector.

You can identify your iPhone 11 Pro Max carrier in the settings menu.

Browse to Settings > General > About > Carrier

* If your iPhone 11 Pro Max doesn't power on, your carrier name or logo might also be imprinted on the SIM card.

If your carrier is not listed, please select “Other”.

All carriers aside from Verizon, T-Mobile, and AT&T fall under the “Other” classification.

If you are currently using a carrier other than the network it was originally locked to, you’ll need to select the original carrier when entering the details for your phone.

For example, if you purchased your phone from AT&T but then switched to another carrier such as Verizon, you’ll need to select “AT&T” for your device details so that you receive an accurate buyback quote.

Use the following condition descriptions to determine the best match for your iPhone 11 Pro Max

* Please note that each store has a slightly different way of determining an item’s condition.

The true value of an iPhone 11 Pro Max depends on its condition and specifications like capacity and carrier. The most important factor will be the cosmetic and operational condition of your device. Of course, the better the condition the more money in your pocket, but the companies we search will even purchase broken devices!

iPhone values depreciate by around 40% over one year, but that rate jumps to 75% over three years. At the same time, values for old iPhone models drop by 15% or more after a new flagship is released. That means you should sell as soon as possible to get the most money for your used iPhone.

Sending your phone to a Flipsy Trust Verified online buyback store is convenient since you’ll get a free printable shipping label and speed payments that are sent within 3 days of delivery. It's also worth mentioning that the buyback stores we search pay cash, not credit like carrier buyback programs which also offer 30% less comparatively.

Unfortunately, local selling options are limited in most areas.

The best option for selling your iPhone 11 Pro Max locally is to list it on a marketplace like Craigslist or Facebook Marketplace. This can be a good route for getting the most money for your iPhone, but be aware that there are several potential drawbacks which include:

• No guarantee of sale
• Fees can reduce profits (listing fees, selling fees, commissions, PayPal fees, etc.)
• Time-consuming listings with phone details, photos, etc.
• Sales can take a long time
• Potential for scams

Another consideration is a local buyback store or kiosk such as ecoATM. Although these offer the likelihood of a same-day payout, they don’t come without cons:

Lastly, most areas have brick & mortar carrier stores like Verizon, AT&T, and T-Mobile, but their trade-in programs often offer 30-50% less than your other options and they typically only offer store credit, not cash!
