[Q] Three Sim working in locked phone. WTF

After not paying my Vodafone bill for a few months, i got disconnected.
As my mobile contract is ending next month i decided to switch over to three pay and go, as they have very good deals available.
I received my new three sim today and tried it in an old Samsung D500 as it is unlocked and my Touch Pro 2 is locked to vodafone.
Well the D500 wouldnt pick up the three sim card, just an 'Insert SIM' error message.
After alot of tinkering with it i though 'F*CK IT'. I'll whack the sim card into my touch pro 2 and see what happens.
To my amazement, the Touch Pro 2 fired up and started downloading connection settings from three to the phone.
HOW THE HELL DID THIS HAPPEN?
I know for a fact that when i got the phone it was locked to vodafone!
Now its accepting any sim card i insert
Any ideas as to why this has happened?
Just interested as to why.
Thanks guys/gals

Hard SPL'ed ?

Hi,
I'm guessing since you are running a custom rom that your device is Hard SPL'ed ? I dont have O.R.D. , so im no expert here , but I think as a result of that, your device is now Sim unlocked .
I know this because i paid for a sim unlock from a respected developer on here who was very helpful , and when i started to run the application, it proceeded to Hard SPL my device . I have to say I hadn't expected that, and promptly pooped myself (i think i mentioned already I'm a ROM virgin ).
Anyway, everything went fine, with no unfortunate side effects, except my phone is now Sim unlocked, and ready for flashing should I ever desire to do so
Regards
Garrickus

Well hey, IM NOT COMPLAINING
I always thought that H-SPL and SIM lock were 2 different things (as a custom ROM/H-SPL is offered free, while phone unlocking on here is at a price)
Its just great i didnt have to pay for it

Got official TMo unlock codes within 24 hours

Phoned 611 yesterday evening and by 2:30am this morning had three unlock codes waiting in my inbox from TMobile.
We have our three SGS4s phones on a business account and had paid for the phones outright.
Only had to way 14 days of active account before they released the unlock codes.
Pretty fast!

Time for me to call in, thanks for the post!

Did the posted unlock method not work for you? I went through the steps, popped in my friend's AT&T sim and was good to go. Made a couple of calls, surfed the web and everything was perfect, APNs loaded automatically when I put in their sim.
I'm on a $20/mo device plan

as long as you have an account and good standing. as well as having the phones for certain amount of time, they are very willing to do it. i have had 2 other phones unlocked on tmobile. first time i had gone to greece. the second time i just told them i was going out of the country. same thing they emailed me the next day

They wanted me to wait 40 days to give me the unlock code(s).
I told them I paid outright for the phones so they came back and said I had to wait 14 days.
The waiting period (if you've paid outright) is 30 days for California and 14 days for the rest (unless your state says otherwise).
They made an error when they set up our business account as we are in California, and said I didn't have 30 says to change my mind but 14. It worked out better because I didn't have to wait for 30 days
They couldn't change the account set up but said any further additions to the account will reflect California.
If you're paying off your phone every month on the new no-contract plan, I think you have to wait 90 days. The CS rep said I had to wait the initial time period because that is the time frame you have to return the phone and if they unlock it, they can't relock it.
I figured that if I was going to get the official unlock code(s) in a few days it'd be better than trying the method shown on the forums here. Just got back from travels so will try and unlock tonight or tomorrow
Still...impressed that it took less than 24 hours. The CS reply sad if they couldn't issue it, they'd have to get it from Samsung directly. One benefit of being on a business account (we only have three phones on home business) is that we get 24 hour CS rep help and I haven't waited more than a minute or two to speak to someone. Well worth the effort of setting everything up through the business.
I hope my info will be of help to others.

Hmmn...weird, two of the three unlock codes worked. Mine failed but the other two were unlocked in under 10 seconds.
TMo CS are escalating the issues to supervisors so will be interesting to see what comes of it and why my code didn't work.
By the way, are there any limits to how many times you can input an incorrect unlock code? I know PUK codes lock you out after so many tries.

i tried that and it didnt work, but i ended up calling and they gave me the code

I have had numerous calls to TMo CS (all very friendly, courteous and helpful) and still no joy in getting the unlock code to work, even though they submitted for an additional unlock code.
The second request came back with the same unlock code from TMo.
I kept getting an "Network unlock unsuccessful" message. The IMEI was triple checked (under battery, on the box and by dialing *#06#), I was told to switch WiFi off - nothing worked!
TMo then gave me Samsung's Equipment phone number (1-888-987-4357) and I spoke to someone there and they told me emphatically that they can not give out any unlock codes...only the carrier can do that.
They send the codes to the carriers when they send out the phones.
It was back to TMo and finally the CS rep says I should take the phone back to the store and see if I can swap it out for a replacement.
I was ready to do that and figured I might as well try the unlock method posted at http://forum.xda-developers.com/showthread.php?t=2283068
Mine showed OFF in step six so I chose Restore Backup from step 4 and restarted the phone. This time, the phone never asked for an unlock code, when I put in a UK 3 SIM card as well as an ATT SIM card. Both of these SIM cards are inactive but I thankfully never got the SIM card error that previously showed up. I will see if I can find someone with an active ATT SIM card to double-check all is working.
So...if anyone is having trouble with an official unlock code, try the XDA tweak :laugh:

Is it better to unroot and take it back and swap it out, or stick with the XDA unlock method?
Some folks are reporting that it reverts back/isn't permanent.
Did TMo online swap out the phone or did a corporate store take it back? I figure it's not worth the time and effort to unroot, take it back to get an official unlock code again if the XDA method does indeed stay permanent. I'm trying the path of least resistance as going to a store to resolve an issue like this is never a ½ hour thing.
The manager at the store I bought the phones said he'd have to look at the phone and make sure I hadn't put in too many incorrect unlock codes — I don't know how he'd figure that out as it never told me I had X amount of tries left to try the SIM unlock.
If I've paid full price from the phone, I really do want it (to stay) unlocked.
Thanks for any feedback.

[Q] SGH i747m

A few days after upgrading to 4.3 my phone stopped reading my SIM card, says Unregistered SIM. I figured the sim card got fried as the phone seemed hotter then normal when I was playing with it while it was charging, so I picked up a replacement sim card though Telus. When I installed new card still had same issue, I chatted to Telus online helper and they suggested my phone may have been flagged as lost or stolen.
I purchased the phone used back in June, it was originally a Rogers phone but I used the key code unlock to unlock it and it worked fine for 6 months. Now when I use Telus compatibility tool it says my phone has been blacklisted as lost or stolen... is this even possible after 6 months? Telus said they cant help as it is a Rogers phone, Rogers won't help because I am not a customer... I don't really believe the phone was reported, but don't get how it ended up on the "Blacklist", I wanted to rollback from 4.3 to 4.1.1 so I could start from scratch but see warnings that it will brick the phone if I try to do that.
Is this a common problem with the 4.3 update, if so is there a fix? If the sellers did wait 6 months to report phone lost or stolen, is there anything I can do to get the phone working again if they won't message me back? I have some of the back and forth messages setting up the deal for the phone, they haven't responded to any of the messages that I have been sending them
Phone is a SGH i747m

[Help] IMEI Issue ( I think)

So I've had my G3 for close to a year now, and just recently my phone's mobile network just stopped working. I thought it was because there was ****ty reception at my house, but the only places it doesn't have good reception was in my room. Anyways, I've had my phone up to now working flawlessly, but until a couple of days ago, like I said, mobile network wasn't working. I checked the apn, didn't have it so I added it even though it was working before. Reboot, and nothing. I tried reseating the sim card, no go. So from some info I gathered online, it was a good idea to check it's imei code. It's been reported lost/stolen and can't be activated, SUPPOSEDLY, even though I was using it fine until a couple of days ago. I thought it was because I hadn't recharged my sim (had a like 2 months without recharging it, and by recharging it I mean buy minutes.) Anyways, I had bought my phone in my home country, Dominican Republic, from an online website like craiglist so to speak. If the imei is reported stolen and can't be activated, is there nothing I can do? It used to be working a few weeks ago and I don't think I can possibly just lock me out like that. Any help would be greatly appreciated. Thanks!

if it's reported lost or stolen then the only option you have is to switch to another company. If it's not that then check your apn settings. If that doesn't work then try and get another Sim card. Sometimes they mess up and make your phone act weird

Sprint Galaxy S6 (G920p)

So I have contacted spring 20 times, they have confirmed my SM-G920p is domestically unlocked. Getting a sim from AT&T and it says invalid Sim. I've searched everywhere, some forums say do a paid service (im fine with) others say unlocking from sprint works....which is obviously doest for my phone.
Anyone actually sucsefully unlocked a spring galaxy s6 (g920p.20) and used it on AT&T network? If so can you give me the details?
Thanks!

Question. Why on this phone in the network mode does it have options to use CDMA, LTE/CDMA, GSM, GSM/UMTS?

GSM AT&T works fine Idk why ppl say it doesn't work I have H2O which uses AT&T and I get LTE. Use a website called willmyphonework to find answers on stuff like this

This is the first website I've created to post about this topic. I've spent the past few days researching and testing out things. So far I've only found a few post online saying it works....I've not heard much about the sm-G920P NOT working on other networks. Also the phone itself is not made for CDMA or GSM ONLY.
One thing is for sure, one of my sm-G920p is domestically unlocked from Sprint. They also gave me a MLS or MSL# or whatever even though I dont think it matters. This phone will not take any AT&T sims. It says invalid sim.
With another sm-G920p, I rooted it and unlocked it another way...obviously not involving sprint. I will test it this evening to see if it accepts AT&T's sim card and will post my findings.
The whole reason for this is we have a business that goes though phones due to physical damage. I have a couple left over phones that I've replaced the screen on myself. I would like to let my sister and fiance use the galaxy S6s as they have old phones! All of these phones have been paid in full FYI and our account is in great standing.

Okidoki. I have spent some time working on unlocking a Spring Galaxy S6 SM-G920P with stock firmware ending in QB1. At first I found out that US carriers now have to unlock your phone if you ask. At first I went that route as it seemed legit. I called Spring and got a guy on the phone from tech support. I gave him the DEC# on the back of the phone and he said "Great thanks.....its unlocked." I though sick!...went to AT&T next day and got a nano sim activated. Once entered the phone read "Invalid Sim". I got back on the phone with sprint quit quickly while at AT&T. The lady said she had to send in a ticket to get it unlocked and the guy before definitely did not unlock it. Went home and went online again. Next day the lady called me at 11am and said it was domestically unlocked. I called back an hour later and talked to someone else confirming it was unlocked. Went to sprint, installed new activated sim...."Invalid Sim". Next thing was to root it and try unlocking it myself.
I found out how to root the phone and install custom firmware and whatnot. Its fairly easy, similar to computer basics. Once that was done I unlocked the phone with a little help which was not hard to find. I went to AT&T and BOOM!!! Phone worked RIGHT away. I was blown away. The phone had voice, data, msg, voice mail 3g and lte. Had my fiance put in her google info.....FYI this is my fiances AT&T account and a spare S6 I had that i fixed the screen on. Anyway she put her google account into it and restarted the phone. At the "samsung" logo login little red letters at the top say something about FRP is locked. The way you bypass this is right after you unlock the phone you need to go into the developer options and enable OEM Unlock. This fixes the lockout. But to get back into the phone once you lock it out you have to re root the phone with its original firmware.
It has worked all evening. Thanks Jhoward you gave me that last little boost today to get it working. I know the SM-G920P phone works in every network so I have no idea why people think it can only work on one network. Something I did learn is that these are little computers.....pretty cool!
If anyone needs any more info pm me.

They lie. It took me 5 calls and many hours to get one of my 2 s6 unlocked. There is some problem with original activation date on some of the phones.
They said both were unlocked but only one worked.... Until finally tech support fixed the activation date.
Now both work on T-Mobile very well

sprint is a little ***** when it comes to unlocking devices. i have never successfully unlocked a device from them. they will run circles of confusion around you just so you won't unlock.

G920P to GSM

Hello localphit, can you help me do the same with my Galaxy S6 G920P. Mines in currently on android 7.0 Patch January 1, 2018. Appreciate all the help that you can give.
