So i've seen quite a few ebay iphones with bad esn be it sprint or verizon. Now ive been looking around and reading many articles, but up till now i havent been able to clarify my situation.
So i hope you guys can help me, because there are too many diverging opinions and too many differing explanations. I need something concrete and sure.
Ok lets say theres an iphone 4s or 5 either verizon or sprint CDMA bad ESN or clean ESN. Ok so both normally have GSM sim capability . Doesnt matter if stolen, out of contract or lost or still has clean esn.
So its CDMA locked right, means that it doesnt use a GSM sim card and is only used on the carrier its locked to. But still retains GSM carrier sim useability properties.
So here is the question:-
1. Can i use a GSM sim card of another carrier "Emtel Mauritius"?
2. If yes is there anything else i need to make it work, jailbreak, unlock etc?
3. Is there any limitations in itunes, does Itunes activate my sim etc, will itunes block the BAD ESN phone?
4. Is baseband freely upgradeable without any consequences?
5. If i get an Rsim7, can i use the Bad ESN phone on the go without trouble.
Thanks for guidance.
I need to be 100% it could be a great save for me.
?? No1 ?? i wouldve expected a few replies with some substantial help by now. Any1 with experience with BAD ESN and can clear my way to cheap iphone 4s or 5.
Hi, what about using the phone that has bad esn (and has a sim card slot and works in GSM mode) abroad? An example is the LG G2 with verizon. Can I easily get one even will have a bad esn, unlock it by IMEI and use for example in France in GSM mode?
Or what if I buy phone that is locked at the factory and has bad IMEI in the United States. Is outside the state without any problem the phone is ready for use? or must be factory unlocked because the bad imei do not get IMEI code to unlock. How is it, please explain to me.
I met with different opinions.

Hi,
I am not really sure what you are trying to do and what you mean by "bad IMEI." I am going to close this thread because it is illegal in a lot of places to even discuss the ways and means of changing an IMEI number. This is largely because blacklisting IMEIs from stolen phones is a strong deterrent against phone theft.
Sorry for the thread closure :silly:
Hello XDA-Developers,
I am at my wits end. I can not for the life of me find a Sim Unlock code for my Samsung Note 3 N900W8.
I will start from the beginning... I purchased this phone from a woman who is the manager of a telecommunications in London ON. She listed the phone on Kijiji as "Brand new in box, unlocked!". I met her at a kiosk for my carrier to test the phone on one of their sim cards. It turned out the phone was sim locked. She seemed nice enough and genuinely surprised when it came up sim locked. She said she had received the phone as a promotional gift from her company, but didn't like the size of it and wanted to use her existing phone. She asked me if I would prefer to have her get it unlocked or she would take 50$ off of our originally agreed price to put towards the unlocking cost. I opted to get it unlocked myself, my mistake lol.
First I had to find out which carrier it was locked to so through a process of elimination I figured out it was locked to Bell. I contacted Bell and asked to get a sim unlock code from them. They said that they have no record of my phone in any of their data bases and that I should contact Samsung and confirm that my phone is locked to Bell. I contacted Samsung who confirmed that my phone is locked to Bell. I contacted Bell again and they put me through to tech support. He was a nice guy, but didn't give me the answer I wanted lol. He said that because my IMEI is not in any of their data bases that there's no way for him to give me a code. He suggested flashing a different kernel and it would remove the sim lock? I'm sorry I am not that knowledgeable when it comes to this stuff. Anyways, I have taken the phone to 3 reputable phone repare shops in my area and tried cellun******.net. All have said that they can't find an unlock code?
You guys are my last resort, any and all help is greatly appreciated.
Thank You!
I was misled by a sales person and I now own a gently used Galaxy S6 from Boost. I was told all S6's were the exact same, and all are unlocked, and I could use it on any carrier. Without a nano sim to test, I took his word for it and purchased it. After getting a nano sim, I just get "Invalid SIM card" error now. I have rooted the phone and tried to open everything up by following: http://forum.xda-developers.com/spr...cess-sim-unlock-sprint-samsung-t3130294/page3
I desperately need to figure out how to get the S6 working on AT&T ... or at least know if I was duped and I need to sell the phone.
NOTE: no, this isn't my 1st rodeo, and yes, I know I am stupid for buying without successful test ... I trusted the guy ...
Thanks !
Return the S6 from where you bought it. Call the police if they will not accept a refund or exchange.
It looks like your SIM is still Locked. But being that Boost Mobile is CDMA off of Sprint, I don't know how many GSM and LTE bands it supports.

Huh?
Why would the police care, unless things are very different over there you want consumer affairs

I know some t-mobile customers already have devices in hand (or will be getting it within a few days). Has anyone checked if the above article is true? Would be awesome to know for all US who aren't on T-mo or any major carrier (I'm on Cricket, No preorders, and no edge listed so far.)
Would be awesome to preorder the ATT version from a place like target, get those preorder bonuses (target has $100 GC + standard 5% off for target card members, so its probably the cheapest place to get it), and then use it on Cricket.
Note: This is primarily meant for US carriers and devices. not other countries, which has different laws and networks.
Yes I'm also wondering how this will work. When I spoke to sales team at CPW they said it would be completely unlocked but knew nothing about the so called locking feature which may happen to us. Uk
Good question, I'm surprised no one has posted the answer yet considering how many people are getting them.
I'm on cricket as well, and planning to get the tmobile s7 due to the unlocked bootloader (at&t is bootloader locked)... It would be nice not to have to pay some company to remotely Sim unlock it
I would like to know too. Thank you!
I'd also like to know whether the phone will download carrier software specific everytime a different SIM is inserted
Im buying mine from samsung direct so id be annoyed if they have the sim region lock in place. im sure they are selling it unlocked and this sim lock is carrier requested.

Are you in canada? If so there is a sim lock when you put in your sim, but you're given an unlock code with the phone if you get it from a samsung store.
no not canada, well thats good to hear about unlock code, as said im pretty sure the sim lock is only for carrier bought gs7 phones.
Work for a carrier: it will lock upon first sim. If you put in a sim after initial Set up it wipes and reboots. Unlock codes are available like any other phone
CPW never lock their android phones. This feature is for carriers to lock if they want and helps Sammy to sell phones to multiple suppliers using the same SKU code rather than different variants. Anyone buying sim free won't have to worry about this and I'm 99℅ sure shops like cpw won't use this. Buying from an operator however is a different story

Seems like this SIM lock applies to carrier phones only and not Global/International aka Unlocked.
My guess is they do this so Samsung can provide everyone with the same standard S7 model to save hassle on carrier specific phones that are locked from the factory so the carrier can pick up any S7 and provide the sim that then locks to that network.
False.. i have 2 phones.. i just got my S7 and i have an iPhone as well ... just switched the sims and works fine...

I dont understand what you are saying...if you stuck a tmobile sim from your iphone and stuck it in your tmobile s7, its still possibly carrier locked to tmobile.
we want to know if you stick a cricket or at&t in your tmobile s7 first, will it lock to those carriers even though your on tmobile or will it require a remote unlock
I'd be curious to know that if id DOES lock, would a ODIN/reflash of stock reset it?
I would love it buying a AT&T version would work on Verizon or T-Mobile.
All this of course with the phone having access to all bands set on initial carrier SIM card boot up.
Is it possible to just flash a different version's os? Example, could i just flash the t-mo fw onto an att phone?

Oh well yeah in that case I'm not sure because I know my phone should be locked to T-Mobile from the start unless I pay it off in full. I highly doubt if I would have put a non T-Mobile Sim in it first that it would of even got service. You would have to ask someone with an unlocked device if another sim works because most devices from carriers are locked from the start.

Best answer here. I'm not sure what the confusion is here. A phone from T Mobile IS locked to T Mobile unless one removes the carrier lock. Its always been this way (sans int. phones). The carrier unlock app is in the S7 as well and by law all US carriers must provide the unlock if requested by a customer.
So if the OP buys an S7 outright then they can request and will receive the unlock for the phone. Otherwise its business as usual.
