What if I get a "Clean" Sprint USA iPhone 4S for a gift from a relation living in the US and it has not been previously activated over Sprint USA's network. Can it be activated over a local GSM carrier's network where I live outside the US? Would I have to approach my local carrier to unlock the device so that it can be activated for use? When I put a local GSM enabled SIM in the phone, it receives the service bars but the screen then says "iPhone not Activated". I need some help here.

First of all, if you just want to be 100% sure that the device is clean, you can use this service:

Sprint USA iPhone Blacklist / Barred checker

That's if you decide to use someone who is offering a "clean only" Sprint USA unlocking service. If you purchase the "clean only" service from a supplier: YES, the device needs to be activated on the Sprint USA network first before unlocking it.

We do not offer a "clean only" unlocking service.

The service that we offer will unlock the device regardless of its status (clean or not) and, NO, it does not need to be activated on the Sprint USA network with the following service:

Sprint USA Premium iPhone Unlock

Thanks for the reply. I checked the Activation Lock status. It returned OFF. What exactly is meant by Country: 226 and Network Provider: 2008. I need clarification before ordering the Blacklist/Barred Check.

StockUnlocks June 21, 2015

Those are internal database lookup references. 226 = United States, 2008 = Sprint USA. The most important information you will receive after ordering will be the device status.

hi  i bought a blacklisted i phone 6 blocked on t mobile usa. i want it unlocked so as to be able to use it abroad. is it possible?   thanks

Hello jigme,

There is a service I have access to, however, it's not available for a barred/blacklisted USA T-Mobile iPhone 6. It's for a CLEAN IMEI only, sorry.

I wish I had a service like what you are looking for, similar to the barred/blacklisted USA Sprint iPhone unlock service that I have. It allows you to use the iPhone outside of the U.S. once unlocked.

I haven't posted the CLEAN IMEI USA T-Mobile service to the website due to lack of demand.

If anyone out there knows of a service for barred/blacklisted USA T-Mobile iPhone, allowing it to be used outside of the U.S. , feel free to leave your comment here.

Purchased iphone 5s on craigslist unaware of bad imei anyway to clear it?

StockUnlocks August 14, 2015

There are some websites that claim that they can clean certain IMEI/ESN that have been barred/blacklisted/blocked.

I'm not sure whether those services really work or not. Some time ago, I removed all mobile and iPhone Unlock Services that involved cleaning a bad IMEI/ESN.

Purchased note 4 on craigslist and was unaware that the imei was blocked.  is there anyway to unlock it? thank you

StockUnlocks August 17, 2015

Please understand that there is a big difference between Unlock and Unblock (or cleaning).

1. When a device is Locked it can only be used on ONE Network provider or carrier. No other SIM Card may be used, only the original carrier's SIM Card may be used.

2. When a device is Blocked (or barred/blacklisted) the device can't be used on ANY network provider in the country of origin (usually). It won't work because the original owner didn't pay their bill or it was reported lost or stolen.

> Unlocking (related to #1 above): also known as SIM Unlocking, allows one to use the device on any carrier, whether locally or abroad. That is, you may use any SIM Card from any network provider as you wish.

BIG NOTE: Blocked/Barred/Banned ESN/IMEI devices can still be UNLOCKED. Yes, they can. It's just that you still won't be able to use the device in the country of origin even though it's Unlocked.

That's why some people SIM Unlock barred/blacklisted devices and sell them overseas to be used in another country. However, with talk of globally sharing blacklists this can be seen as becoming a problem in the future.

> Unblocking (related to #2 above): also known as cleaning the bad ESN/IMEI, restores the "good standing" of the device's ESN/IMEI. This allows it to be used, once again, on the network from which is was banned. No one usually goes back to the original network.

Usually, after "cleaning" the bad ESN/IMEI, the device owner will proceed to SIM Unlock the device in order to use it on another Network provider in the same country.

With all of that said and as I continue to point out to everyone, we do not clean or "repair" bad ESN/IMEI devices. Please follow the conversation above and read the links already provided. Thanks,

Hi I am from Chile, Southamerica. On ebay I noticed they were selling some samsung galaxy phones with bad ESN. Is it possible to buy that phone with bad ESN and use it in my country with local companies that uses sim cards with GSM?? Thanks   Martin

StockUnlocks September 09, 2015

Hi Martin,

Normally, bad ESN phones cannot be used in the country of origin once unlocked. Technically, yes, you should be able to use it in Chile, once it is carrier unlocked. You will just have to find a supplier who unlocks bad ESN Samsung Galaxy phones.

So if an iPhone has a bad esn with at&t, am I still able to connect to my t mobile account or no?

StockUnlocks September 09, 2015

Hello Joey,

Similarly with Martin's case above: However, in your case, no, normally you are not able to use a bad ESN phone on a network in the country of origin where is was flagged as a bad ESN.

In your case the iPhone is on AT&T (USA) and has a bad ESN. T-Mobile (USA) normally shares blocked/barred lists with other USA carriers, so your device will be blocked from being used in the USA.

Once unlocked, it can only be used outside of the USA.

Hi, I bought an iphone 6, checked the imei and results to be clean (it's locked in EE UK). However, when I tried to unlock it it did not work. I was told that it might be a problem of unpaid bills or so. I was looking for a solution and I came across this website. Is it a question of bad ESN even if the IMEI is clean? If so, what can I do so that I can unlock it and use it in order network? Thanks!

StockUnlocks September 13, 2015

Hi Adriana,

Actually: Clean IMEI = Clean ESN and vice-versa. You cannot have a clean IMEI and a bad ESN at the same time.

If you pay for a service to check your IMEI and the report informed you that it was "clean", then your device does not (should not) have a bad ESN.

Some unlocking websites have services to unlock "clean" or "bad" IMEI/ESN devices. The "clean" unlocking service is much cheaper than the "bad" IMEI/ESN unlocking service. Some websites will post only the "clean" unlocking service but charge the higher price of the "bad" service. The website will accept all, clean and bad, in attempts to profit.

Then, they will say "sorry" for the orders that fail and move on.

What can you do?

1. Be sure to use a paid service when you check the clean/bad status of your IMEI/ESN. Make sure that the service is specific to your device and network. That's the only way to be 100% sure of its status.

2. Keep in mind that, if the device's IMEI/ESN is bad, once unlocked it can only be used outside of the country of which it was previously locked to.

3. If the IMEI/ESN is bad and the device's origin is the same as the country you live in, decide whether you want to unlock and sell the device, because you can't use it in your country.

All the best

Hi, thanks for all the info! Could you please, recommend a good service to check the IMEI? I would like to be sure before trying to unlock it again. The phone was bought in UK but I live in The Netherlands, so if there's still a chance I'd like to try.

We have a service that is guaranteed to give you an accurate report regarding your iPhone IMEI status. Please see the details here:

StockUnlocks September 16, 2015


There is no service that I know of that will find the information you are looking for. Original Account user's name and phone number are private information. Without personally knowing the original owner yourself, there is nothing else you can do other than doing your best to track them down yourself, sorry.

I looked up my iPhone 5 imei On a website & it said its reported " lost / stolen " blocked by Atleast one carrier & the activation status said " cannot be activated . If I get a GSM sim would I be able to activate it with metro pcs ?

I have a Virgin Mobile (VM) 5S I purchased from them in August 2014. In May 2015, I wanted an iPhone 6Plus (bigger screen), but VM had stopped selling iPhones then and so I went to Consumer Cellular (CC), transferred my phone number and closed my VM account. Now I want to use my 5S on CC for another family member. But VM will not unlock my 5S as their "policy" is you have to have used it for 12 months at VM, even though the phone was fully paid for at VM in May 2014. Never mind I had been with VM since 2011 with other phones and only switched when they temporarily stopped offering any iPhones for a few months. I have checked and my ESN is not blocked. I have found very little success finding services to unlock my 5S - VM is apparently not offered on your site. Why is it so much trouble to unlock a Virgin Mobile 5S iPhone? Do you have any recommended solution other than calling VM? After escalating my problem (pleading my case) through 3 levels of supervisors there who said there was nothing they could do to unlock the phone, they finally convinced me they would do more research and a Manager would call back - but never did of course.
