There is no iOS-specific tool for verifying the network eligibility of a given iPhone or iPad. Instead, if you’re thinking about buying an iPhone secondhand, follow the same procedures as purchasers of Android devices to verify the device. We show you how to do so using all currently supported versions of iOS.
What to Know
- Obtain the IMEI number: Go to Settings > General > About to view the IMEI. If the seller doesn’t disclose the IMEI, don’t buy it.
- Call your wireless carrier to see if the iPhone is blocked on the network.
- Check the CTIA Database, which includes a pooled collection of stolen phone data.
How to Obtain the IMEI
Your first step before buying any used iPhone is to obtain the device’s IMEI number. The International Mobile Equipment Identity number serves as a unique identifier for a specific telecommunications device. If a secondhand seller refuses to disclose the IMEI, do not proceed with the sale.
On an iPhone, visit Settings > General > About to view the IMEI.
Call Your Carrier
If you’re a customer of the wireless carrier, call the carrier to see if the iPhone is blocked on the network. Although this method isn’t perfect, odds are good that because networks align to radio types (CDMA versus GSM), your carrier will know if the device can be activated on its network.
To obtain the IMEI for most devices, including non-Apple hardware, check the inside of the battery compartment or dial *#06# on the handset.
Check the CTIA Database
Although it, too, isn’t perfect, the CTIA stolen-phone database is a pooled collection of stolen phone data. The major U.S. carriers consult it and contribute data to it. It’s only potential weakness is that a phone might not be reported stolen—for example, an old phone in a drawer pilfered by a thief.
As with any private transaction, a dose of skepticism helps. If a phone sale seems suspect, it probably is.
