METOD 1


1. Turn on the phone whithout sim card
2. Lock screen
3. Press sequence:
Menu, Back, Back, Menu, Back, Menu, Menu, Back
4. Select Service info
5. Select SimLock
6. Check where is X
7. If X is on NETWORK and value is different than zero, you can unlock your phone.

DETAILED FULL EXPLANATION WITH EXAMPLES




[x] network 10
[] network subset 10
[] service provider 10
[] cororate 10
[] sim 0


If there is an X beside any of the categories, then means you need specific code to unlock that phone.  
Normally, Sony Ericsson phones come only with a network lock as active.  
The most important part of this is to view the numbers beside each category. 
That number represents the number of tries you have left before your Sony Ericsson device becomes permanently hard locked to its original network carrier.  
If there is a 0 beside the category where a lock exists, then it means that your phone is hard locked.


Example 1:
   
[0] Network 1
    [x] network subnet 0
    [x]service provider 0
    [x]corporate 0
    [x] Sim 0

 This phone is locked and you still have 1 attempt to enter the Unlock Code


Example 2:
   
[0] network 3
    [x] network subset 0
    [x] Service provider 0
    [x] cororate 0
    [x] sim 0

This device can be unlocked and have 3 attempts left to enter the Unlock Code


Example 3:
Sony xperia Z from nttdocom japan model (SO-02E)...
   
[×] network unlimited
    [ ] network subset 0
    [ ] service provider 0
    [ ] corporrate 0
    [ ] sim 0

This device has normal network lock and can be unlocked 


Example 4:
 
  [0] network 7
    [ x] network subset 0
    [ x] service provider 0
    [x ] cororate 0
    [x ] sim 0

This phone still has 7 tries left to enter the Unlock Code


Example 5:
xperia ion lt28 Etc..
   
[x] network 10
    [ ] network subset 0
    [ ] service provider 0
    [ ] cororate 0
    [ ] sim 0

 The [x] next to “network” means that phone is still locked Have 10 Tried Left


Example 5:
 
  [X] Network 0
    [] Network subset 0
    [] Service provider 0
    [] Corporate 0
    [] Sim 0

The [x] next to “network” means that your phone is locked and you have 0 tries left, so it cannot be unlocked. 
This means your device is hard-locked and cannot be unlocked by Code anymore (0 attempts left). This Need Any Software Solution to Unblock Counter.


Example 6:    
   
[o] Network 0
    [x] Network Subnet 0
    [x] Service Provider 0
    [x] Corporate 0
    [x] SIM 0

This device Also hard locked and cannot be unlocked by Code anymore

Example7:
 xperia Ion lt28 when insert sim phone restart every min!
   
[] network 0
    [] network subset 0
    [] service provider 0
    [] corporate 0
    [] SIM 0

This device fully unlocked there is no symbol in any of the brackets and Restart issue is not related to the lock Subject - this device is unlocked


Example 8:
 
  [] network 10
    [] network subset 10
    [] service provider 10
    [] cororate 10
    [] sim 0

No symbol inside any of those brackets, device is already unlocked One


Example 9:
 
  [] network 5
    [] network subset 5
    [] service provider 5
    [] corporate 5
    [] sim 0

This device is Not Locked and will remain permanently unlocked even flash with custom or Any New ROM.
    
Example 10:
What if the menu looks like this?
   
[?] network
    [?] network subset
    [?] service provider
    [?] cororate
    [?] sim

There is no X next to any of the menu points, it usually means phone is already unlocked.

​​CDMA vs. GSM: What's the Difference?
(Basically by PCMAG.COM)
 

If you're shopping for a mobile phone, you're in for a lot of acronyms. Here's what you need to know about two basic, yet important, terms. 

CDMA vs. GSM: What's the Difference?


Two basic technologies in mobile phones, CDMA and GSM represent a gap you can't cross. They're the reason you can't use many AT&T phones on Verizon's network and vice versa. But what does CDMA vs. GSM really mean for you?
CDMA (Code Division Multiple Access) and GSM (Global System for Mobiles) are shorthand for the two major radio systems used in cell phones. Both acronyms tend to group together a bunch of technologies run by the same entities. In this story, I'll try to explain who uses which technology and what the real differences are. 

Which Carriers are CDMA? Which are GSM?


In the U.S., Sprint, Verizon and U.S. Cellular use CDMA. AT&T and T-Mobile use GSM. 
Most of the rest of the world uses GSM. The global spread of GSM came about because in 1987, Europe mandated the technology by law, and because GSM comes from an industry consortium. What we call CDMA, by and large, is owned by chipmaker Qualcomm. This made it less expensive for third parties to build GSM equipment.
There are several variants and options carriers can choose, like toppings on their technological ice cream. In this story we'll focus on U.S. networks. 

What
CDMA vs. GSM Means to You?


CDMA phone DO NOT accepts unlocking code and is NOT unlockable, meaning:

CDMA phone you CAN NOT use in another carrier different from the original one.
GSM phone accepts unlocking code and is unlockable, meaning:

GSM phone once unlocked you can use in any other GSM carrier.

For call quality, the technology you use is much less important than the way your carrier has built its network. There are good and bad CDMA and GSM networks, but there are key differences between the technologies. Here's what you, as a consumer, need to know.
It's much easier to swap phones on GSM networks, because GSM carriers put customer information on a removable SIM card. Take the card out, put it in a different phone, and the new phone now has your number. What's more, to be considered GSM, a carrier must accept any GSM-compliant phone. So the GSM carriers don't have total control of the phone you're using.
That's not the case with CDMA. In the U.S., CDMA carriers use network-based white lists to verify their subscribers. That means you can only switch phones with your carrier's permission, and a carrier doesn't have to accept any particular phone onto its network. It could, but typically, U.S. carriers choose not to.
Many Sprint and Verizon phones now have SIM cards, but that isn't because of CDMA. The SIM cards are generally there for Sprint's and Verizon's 4G LTE networks, because the LTE standard also uses SIM cards. The phones may also have SIM slots to support foreign GSM networks as "world phones." But those carriers still use CDMA to authenticate their phones on their own home networks.
3G CDMA networks (known as "EV-DO" or "Evolution Data Optimized") also, generally, can't make voice calls and transmit data at the same time. Once more, that's an available option (known as "SV-DO" for "Simultaneous Voice and Data Optimization"), but one that U.S. carriers haven't adopted for their networks and phones.
On the other hand, all 3G GSM networks have simultaneous voice and data, because it's a required part of the spec. (3G GSM is also actually a type of CDMA).
So why did so many U.S. carriers go with CDMA? Timing. When Verizon's predecessors and Sprint switched from analog to digital in 1995 and 1996, CDMA was the newest, hottest, fastest technology. It offered more capacity, better call quality and more potential than the GSM of the day. GSM caught up, but by then those carriers' paths were set.
It's possible to switch from CDMA to GSM. Bell and Telus in Canada have done it, to get access to the wider variety of off-the-shelf GSM phones. But Verizon and Sprint are big enough that they can get custom phones built for them, so they don't see the need to waste money switching 3G technologies when they could be building out their 4G networks.

Phones Unlocked  by  iTechUnlimited Until Now:

METOD 2


1. Turn on the phone whithout sim card
2. Type
*#*#7378423#*#* (In new models can be used  #987654321# )
3. Select Service info
4. Select SimLock
5. Check where is X
6. If X is on NETWORK and value is different than 0, you can unlock your phone (
PICTURE 1).
7. If it is 0 unlock by code is NOT possible, The counter is blocked (
PICTURE 2).

8. If it is zero unlock by code is NOT available. The counter is blocked.​​

What does it mean that your phone is HARDLOCKED?

 

It means that your phone is permanently locked (no code will unlock it), and you cannot use it to make any calls, or send messages. 

This may appear after entering an incorrect unlock code too many times, when your code counter drops to zero (zero attempts left), or when you try tried to change the software of your phone for an illegal one. 

Please check the code counters before making an order, and don't change the software.
