Explanation checks by IMEI for iPhone: learn to "read" GSX

Explanation checks by IMEI for iPhone: learn to

Ordering an check by IMEI or SN (serial number) for the iPhone or iPad, it is important to be able to correctly read it and decipher the information received. Support from imei-server is always ready to help with the decoding of any result (support@imei-server.com), but if you prefer to understand everything on your own, this article will help you learn how to correctly read the results of GSX reports.

Let's look at the key lines of the various checks and determine what the corresponding result means.
The GSX check is primarily intended to check the status of the device lock: locked to the operator or not, but many other additional data can be included in it. The kind of results from different providers can be very different and sometimes it's just plain text, without line-sharing. In this case, it is especially important to know what kind of information you need to look for and what to look at.
The lock status always displays two important lines and both need to be taken into account. The most important, decisive, is the first line:
  1. "Next Tether Policy Description:" - Description of the thread binding policy.
  2. "Unlock Date: Unlocked:" - Date of unlock and unlock status
Next Tether Policy Description: Multi-Mode Unlock - means the phone is full unlocked and will accept other SIM cards. The second line can display such data:
  • "Unlock Date: 29/12/16 Unlocked: true" - indicates the date of unlock and the status of the unlock.
  • "Unlock Date: Unlocked: false" - if the first line shows unlock, and there is no information about the unlock date, it means that the phone is unlocked, it just was not activated. After the SIM card will be installed and the phone will be updated, the unlocked date will be automatically assigned. The repeated result of the IMEI check, ordered after activation, will already display the unlock date and it will correspond to the activation date of the device.
Next Tether Policy Description: US Sprint / MVNO Locked Policy - means at the moment the iPhone is locked and will not accept other SIM cards. This example shows a lock on the US Sprint operator. The lock from any other operator will look exactly the same.
  • "Unlock Date: Unlocked: false" - when the first line shows locked, then the second line, too, should not have any information. This means that we are dealing with a conventional locked device that did not pass the unlock procedure.
  • "Unlock Date: 29/12/16 Unlocked: true" - if according to the first line the phone is locked, and the second line opposite - displays the unlocked date and the status of "Unlocked: true", then it means in our hands the device that passed the unlock, but unlock "flew" and it was blocked again. Such a "contradiction" as a result is a classic example of a relock (re-lock-repeated blocking).
It is worth noting that the repeated unlocking of phones that have already been re-locked, is likely to be temporary and eventually "fly off" in the same way. It is impossible to predict how long such a device can be successfully updated.
Next Tether Policy Description: 2116 Russia Reseller Unlock Policy - iPhone is not locked and will accept any SIM card. Some devices do not have a binding to any network by default. For such devices, you will always see the name of the reseller with the prefix "Unlock Policy" in the main line.
  • "Unlock Date: Unlocked: false" - the phone was not locked, but it was not activated.
  • "Unlock Date: 29/12/16 Unlocked: true" - the phone is not locked, the specified date of "unlock" is the date it was activated by the SIM card.
Next Tether Policy Description: US GSM / VZW N61 / N56 Service Policy - in this case there is no a word - "locked" or "unlocked", but this iPhone is locked. Here we are dealing with a lock to the region, rather than on a specific operator. Other examples of regional blocking are:
Next Tether Policy Details US Reseller Flex Policy - in this example we see another type - "flexible binding policy". This result is typical for a device that has not yet been activated. The phone will "snap" to the operator whose SIM card is first installed in it. With this result of the main line, the second line always looks like this:
  • "Unlock Date: Unlocked: false" - the phone is locked and has not been activated.
After we has examined the basic rules for determining the status of the lock on the operator, let's consider which the other information can be contained in the GSX report.
Initial Activation Policy Details / Initial Activation Policy Description / Initial Activation - different names of the same line: contains information about the initial activation policy. If there is no information in this line, the device was not activated by the SIM card. In some examples, instead of an empty line may be indicated - "Not Available", which is essentially the same thing. After activation, in this line  will be indicated that operator, by the SIM card of which the phone was activated. For devices that are not initially locked, may be indicated - "Multi-Mode Carrier Policy"
Initial Activation Policy ID: - the identifier of the initial activation policy. This is a number that indicates a policy of a certain type. Quite often, this number can not be taken out in a separate line, but is indicated right before the name of the operator / type of policy. Examples:
  • 2174 US Sprint/MVNO Locked Policy
  • 2104 P10x Multi-Mode Carrier Policy
  • 2116 Russia Reseller Unlock Policy
  • 261 Singapore StarHub Unlocked Policy
Applied Activation Details / Applied Activation Policy Description / Applied Activation - different names of the same line: contains information about the applicable activation policy. Contains the same data as the Initial Activation Policy.
ICCID (Integrated Circuit Card IDentifier) ​​is a long SIM card number. It is unique for each SIM card and indicates that the device is activated and used. For a non-activated device, this information will not be available.
MAC Address - is an identifier number consisting of Latin capital letters and numbers, this number is important when entering the network. For some Wi-Fi-routers MAC Address of your devices should be entered manually, indicating which devices with which Mac-addresses can go through it on the Internet.
Product iOS Version / Product Version - version of the operating system (at the time of ordering the check).
First Unbrick Date is the date of the first restoration through iTunes.
Unlock Date is the date of unlock. If the phone was not locked by default, this date will correspond to the date the device was activated by the SIM card.
Unlocked: - This is the lock status. Here either "Yes / No" or "true / false" can be spelled out.
In rare cases, for some checks, GSX can be supplemented with data about the country of sale, the seller, the status of the guarantee and the contract. These are the lines:
Purchase Country: - Country of sale
Estimated Purchase Date: - Date of sale
Registration Date: 
Warranty Status: - still on warranty or no
Apple Limited Warranty Days Remaining: - how many days left before the warranty expires
Contract Details Contract Type: - type of contract
Contract Coverage Start Date: - start date of the contract
Contract Coverage End Date: - end date of the contract
When ordering the GSX check, it is worth noting that the result may differ from the example in the service description, since we can periodically cooperate with different providers by connecting to the fastest or currently available server. And if it is of fundamental importance for you to receive specific information in the GSX report, always ask our support before placing an order, what is the probability that these data will be exactly in your result. GSX-strings, that are always present in any result, is the data about the initial activation policy, about binding policy, and the lock status. All other data are additional.
