How do I know if my ZTE MF190 is carrier locked?

Read Settings -> General -> About -> Carrier Lock, or run an IMEI SIM lock check. Anything other than "No SIM restrictions" means the device is locked.

Does unlocking a ZTE MF190 remove iCloud or MDM?

No. Carrier unlock, iCloud Activation Lock and MDM supervision are three separate locks; only the carrier lock is affected.

Will the unlock survive an update?

Yes for a server-side release, because it is written against the IMEI at the manufacturer. Interposers and profiles are lost on the next update.

Which TAC identifies a ZTE MF190?

Our register lists 19 TAC ranges for this model, starting with 01404500, 35543504, 35635804.

Carrier lock

Not verified yet

A model lookup cannot read the lock. The $0.03 SIM lock check names the operator that owns the IMEI in about a minute.

A ZTE MF190 is locked the same way any ZTE handset is: the carrier that sold it holds a record against the IMEI, and the device refuses every other SIM until that record changes. This page shows how the model is identified in the TAC register, what kind of lock it uses, and which of our services apply.

Before you pay anyone. Run the $0.03 SIM lock check first. If the phone is already unlocked, every unlock tier on this page is a waste of money — and the check tells you in seconds.

How a ZTE MF190 is identified

The TAC — the first eight digits of the IMEI — is how the register knows which model a handset is, and it is what every unlock and warranty service actually queries. Our register holds 19 TAC ranges under this model name:

TAC prefix	Look it up
`01404500`	run the lookup
`35543504`	run the lookup
`35635804`	run the lookup
`35753404`	run the lookup
`35972803`	run the lookup
`86054700`	run the lookup

Dial *#06# to read the IMEI, then compare the first eight digits. Not listed? The lookup will still resolve the model if the range is filed under a different name.

Which lock does this model use

Most handsets from this brand are either code-locked (the phone prompts for a network code when a foreign SIM is inserted) or released by the carrier that sold them. Which one applies depends on the model year and on whether it was sold through an operator — the IMEI check tells you before you pay for anything.

On a ZTE MF190 the practical test is simple: insert a SIM from a different network. If the phone asks for a code, it is code-locked. If it refuses with “SIM Not Supported” or a carrier-lock notice, it is server-side locked and has to be released against the IMEI. If it just works, it is already unlocked.

Unlock ZTE MF190 by carrier

Unlock prices depend on the carrier and the model generation, so the same handset costs different amounts depending on who sold it. These are the carriers we hold a service for:

Telstra1 tier from $9 Optus1 tier from $4 Vodafone1 tier from $9.50

What to do, in order

Read the IMEI (*#06#) and confirm the model above — a mismatched model is the most common reason an order is refused.
Run the SIM lock check and the carrier check: about six cents, and they name the operator that owns the record.
Run the blacklist check if you are buying the device rather than unlocking your own.
Order the tier that matches the reported carrier — or, if you are the account holder and the device qualifies, request the free unlock from the carrier.
