NETWORK LOCKED PHONES
Can I Sell a Network Locked Phone?
Yes. Zextons buys eligible phones locked to major UK mobile networks, including EE, O2, Vodafone and Three.
You do not necessarily need to unlock your phone before checking its value.
When getting your quote, simply select the correct:
01
Phone model
02
Storage capacity
03
Network
04
Condition
A network-locked phone may be worth slightly less than the equivalent unlocked handset because fewer buyers can use it immediately. Your network status is therefore considered as part of the valuation.
UNDERSTAND THE DIFFERENCE
What Is a Network Locked Phone?
A network-locked phone is restricted to a particular mobile network. For example, a phone locked to EE may not accept a Vodafone, O2 or Three SIM until the network restriction has been removed.
Unlocked
The phone can generally be used with compatible SIM cards from different networks.
Activation Locked
A security feature such as Apple's Activation Lock or Find My remains connected to a user account.
Screen or Passcode Locked
The handset itself cannot be accessed without a PIN, password or security credential.
IMEI Blocked or Blacklisted
The device's IMEI has been restricted from using mobile networks, which can happen when a phone has been reported lost or stolen.
Important:
These terms should not be treated as interchangeable.

PHONE VALUATION
How Much Is My Network Locked Phone Worth?
There is no single price for a network-locked phone. Its value depends on several factors working together.
Phone Model
Newer or more desirable phones will usually have a different resale value from older models.
Storage Capacity
A 256GB version of a phone may be valued differently from its 128GB equivalent.
Condition
Scratches, cracked glass, battery faults, damaged cameras and other defects can affect the valuation.
Network
A phone restricted to one network can have a smaller potential resale audience than an unlocked handset.
Current Market Demand
Smartphone values move as new devices launch and demand for older models changes.

Your device, specification, network and condition all contribute to the valuation.
NETWORK STATUS
Does Being Network Locked Reduce My Phone's Value?
It can. An unlocked phone normally has greater resale flexibility because a future owner can potentially use it with a wider range of compatible networks.
A network-locked handset is restricted to a smaller pool of users unless it is subsequently unlocked. That does not mean a network-locked phone has no value.

DEVICE STATUS
Network Locked vs Blocked or Blacklisted Phone
A phone being network locked is not the same thing as being blocked or blacklisted.
| Device Status | What It Means |
|---|---|
| Network locked | Restricted to a specific mobile network |
| Unlocked | Can generally use compatible SIMs from multiple networks |
| IMEI blocked | Mobile-network access has been restricted |
| Reported lost or stolen | Ownership/security issue associated with the device |
| Activation locked | Still connected to an Apple/Google account or security feature |
You should only sell a device that you legally own and are entitled to sell. If your phone is simply locked to EE, O2, Vodafone or Three, that is a different situation.

CHECK YOUR PHONE
How Do I Check if My Phone Is Network Locked?
You don't need to guess. There are several practical ways to check.
Try a SIM From Another Network
Insert another compatible SIM. If the handset rejects it or displays a network restriction message, it may be locked.
Check the Phone's Settings
Some phones display carrier or SIM-lock information within their settings.
Contact the Mobile Network
The network that originally supplied the phone may be able to confirm whether it is locked.
Check Your Original Purchase Information
Your original contract, receipt or network account may also provide useful information.
