Samsung Galaxy A13 4G

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 Samsung Galaxy A13 4G is locked the same way any Samsung 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 Samsung Galaxy A13 4G 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 145 TAC ranges under this model name:

TAC prefixLook it up
35001388run the lookup
35017873run the lookup
35063754run the lookup
35074647run the lookup
35076859run the lookup
35091828run 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

Samsung devices can be locked two different ways. Older and mid-range models prompt for an NCK / MCK code that is derived from the IMEI and typed on the keypad. Flagships from roughly 2020, and all US carrier variants, are locked server-side like an iPhone and have to be released by the carrier instead.

On a Samsung Galaxy A13 4G 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 Samsung Galaxy A13 4G 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:

AT&T9 tiers from $0.07T-Mobile5 tiers from $0.07Verizon3 tiers from $0.08

What to do, in order

  1. Read the IMEI (*#06#) and confirm the model above — a mismatched model is the most common reason an order is refused.
  2. Run the SIM lock check and the carrier check: about six cents, and they name the operator that owns the record.
  3. Run the blacklist check if you are buying the device rather than unlocking your own.
  4. 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.
