The three descriptions are not interchangeable

  • An unlocked iPhone is described as accepting supported carriers without a carrier lock, subject to model and network compatibility.
  • A carrier-locked iPhone is restricted by the carrier policy attached to that device.
  • A SIM-adapter setup uses an additional component or configuration to obtain service on a locked device. Its behavior can depend on the carrier, SIM, software and setup method.

What wholesale buyers should verify

Ask for the exact model number, carrier-lock status shown on the device, supported SIM format, activation status and a test on the destination carrier where possible. Confirm whether resetting, updating or changing the SIM affects the current setup.

If a phone has been converted for dual-SIM use, ask what was changed, whether the modification affects sealing or service, and how both SIM slots were tested. A general phrase such as “all-carrier 5G” should be verified against the destination network.

How to describe the item to your customer

Keep the original network disclosure in the resale listing. Do not shorten a SIM-adapter phone to “unlocked.” State the market edition, current lock status, required setup and any limitation that was included in the supplier confirmation.

A practical pre-payment check

  • Match the device identifier to the inspection record.
  • Confirm voice, data, SMS and hotspot behavior on the intended network.
  • Record the software version and whether an update or reset was tested.
  • Put the accepted lock and SIM status in the written quotation.

Frequently asked questions

Is a SIM-adapter iPhone the same as an unlocked iPhone?

No. A SIM-adapter setup is a separate configuration used with a locked device and should be disclosed and tested as such.

Does “all-carrier 5G” guarantee service in every country?

No. Network support depends on the exact model, bands, carrier policy and local service. Confirm compatibility for the destination carrier.

What should I ask about a converted dual-SIM iPhone?

Ask what was changed, how both SIMs were tested, whether sealing or service is affected, and whether the configuration survives reset and update.
