1 / 4
01
Type the carrier name. We list the major United States, United Kingdom, Canada, and Europe networks that still sell locked phones.
02
A new SIM goes in. The phone refuses the network. Shops quote a remote job. The carrier asks for a contract you already left.
iPhone
Apple shows SIM Not Supported, SIM Not Valid, or This SIM is from a different carrier. Fix iPhone SIM Not Supported.

Android
Samsung, Motorola, and others show Invalid SIM, SIM not provisioned, or Not registered on network. Unlock a Samsung from its carrier.

03 / Factory carrier unlock
The tower checks the IMEI before a new SIM can attach. A reset does not move the phone. Settings will not add a network the carrier never allowed.
Why the network check wins
The carrier keeps an allowlist for that IMEI. That is why a new SIM shows SIM Not Supported or Invalid SIM. Apps that only edit the phone bounce after a reboot.


Legal and safe
These resources are for people who own the phone. Official carrier desks and partner platforms both ask for proof. Stolen, lost, or fraudulently obtained phones are out.

What we do not do
04 / Technical overview
The radio asks the home network if that IMEI may attach. The answer sits on the carrier side. That is why a factory reset still blocks the next SIM.

Network-side control
Not a setting on the handset
At retail the carrier writes the IMEI into its allowlist. The phone can call that network. A SIM from another operator fails the same check.
The link survives a wipe, a firmware update, and a new eSIM download. The radio has to pass the carrier check on every attach.
What still hits the carrier
Why local edits fail
The phone cannot approve its own IMEI. The network has to clear it. We do not call the carrier for you. You get the walkthroughs, unlock tools, and partner-platform access used on those paths.
All of these still ask the home network
Prepaid retail locks and postpaid contract locks look the same on the SIM screen. The path out is different.

Usual blockers
On an account
The line is still on a bill. The carrier can refuse until the contract or device payment is clean.
Usual blockers
Legitimate methods need the account, paperwork, or a professional platform you operate yourself.
If the account is clean and the wait is over, the carrier can clear the IMEI.
They usually want the IMEI, the account holder, and proof the device is paid off.
Many prepaid brands unlock after a published number of days on their service.
The policy page for that brand is the source. Results still vary by device history.
When the carrier desk is closed or the receipt is gone, the walkthroughs, unlock tools, and a voucher with prepaid credits for a professional phone unlocking platform are the next step.
You run the job on a phone you own. We do not perform the unlock. Results vary.
Watch the seller drop in a SIM the phone is not sold for. If the radio rejects it, you are buying a lock. Random IMEI sites can leak the number.
An official unlock can take days. A refused request does not mean a tool path will work. Eligibility and results vary by device, carrier, and condition.
