[Q] Unlocking Captivate Without SIM

Hello all,
I'm new to all this unlocking and rooting thing so I wanted to ask you something.
Today I ordered from Amazon Samsung Captivate Galaxy S AT&T branded. The thing is that I live in Georgia, so there is no such thing as AT&T
I read as much to learn that I need to unlock my phone, but no one has ever mentioned if it's possible without having the branded SIM card.
So can I unlock my phone without having AT&T SIM card?

Yes you can unlock without sim card. If you get service through any carrier other than at&t that uses sim cards, you will be asked for unlock code.

Once you insert sim from "other carrier" the phone will ask for unlock code.. enter code at this time.

I do believe there is an app, that will find and store the code. Then when you insert other carriers sim, it unlocks automatically. There are quite a few posts about unlocking in the developement section..

First of all thank you very much for lightening-quick reply.
I'll try to look but I've never had an android and I'm interested, will it start without sim card? if not, how can I install the app for generating unlock code? or did you mean to get code by PC app?
Thanks in advance,
Gio

Ya your phone will start without a SIM card in it, and i believe the app he was reffering to earlier was one found in the android market

Thank you all
That feels much safe
Thank you all for your time
I think I'll handle from here

[Q] Is there a way to unlock sim for free?

Im planing to get incredible s but is locked to yes optus (australia).
I have done a quick research.But still couldnt find any tool to unlock it.
Does flashing custom rom unlock the sim? what about bootloader unlock? and s-off? hboot?
what about this radio thinggy ( http://forum.xda-developers.com/showthread.php?t=1129014 )
Is there a free way to remove the sim lock?
thanks in advance

Nope, you can't unlock sim for free. Best bet is to look on ebay for sellers who will sell sim unlock for $4-5. Here is one for $5.99:
http://www.ebay.com/itm/HTC-SENSATION-4G-WILDFIRE-S-INCREDIBLE-S-VIRGIN-Canada-Unlock-Code-/320790616890?pt=LH_DefaultDomain_0&hash=item4ab09c5b3a
Otherwise the only way to get it is:
1) Buy the code from others who manged to get the algorithm from the OEM (that's the sellers you see on ebay and places like cellunlock.net)
2) you need to figure the algorithm for the unlock sequence that is dependent on the base IMEI, so you would have to spend hours and hours of hacking if you even want to try it.
3) buy an "unlock box" that some technicians/hackers use to unlock handsets, but this is much more expensive and costs several hundreds in US $.
You don't loose the sim unlock. Once you do it the first time, it's permanently unlocked forever unless you turn it in for a new one or something. Flashing RUU, roms won't make it lose it.

If your using the phone with a provider that uses the Optus network you don't need to worry about unlocking it, I'm using an Optus sourced phone on Live Connected and it works fine I have not unlocked anything.
I'm planning to flash a custom ROM, but am currently using the phone with the stock ROM that it came with from Optus.

Its locked to optus but the reason you can use the liveconnected sim is because they are an optus reseller, along with Amaysim, Apex, Boost, Dodo, Exetel, Pennysim, Primus, Savvytel, Soul, Startel and TPG. All of these companies sim cards should work in your phone. Virgin, although using the optus network is different I believe, as it is a wholesaler.

Ive used many sim cards in Australia and overseas and it works fine, even before I rooted.

Question about sim chip on incredible s

I was wondering if someone could advise me on the ability to use a different sim chip while traveling to another country.
Is it true that while my phone is s–off through the use of the revolutionary tool, that I still won't be able to use a different sim chip with this phone until I unlock it with one of those xtc-clips?
I just want be sure before I think about purchasing one of those clips for +$80.
Thanks

You can also just ask your carrier for the unlock code if it is a branded phone. Otherwise ou could use one of the pay services and purchase an unlock code for less than the cost of the XTC Clip

Just want to be sure I'm understanding you correctly.
I am with Virgin mobile in Ottawa, Ontario. I plan to use a different sim chip now that I am in Peru for a couple of months. Once I put in this Sim it asks me for a PIN to unlock the sim. Who provides me with that pin? Virgin mobile of Ontario or the sim provider in Peru?
Sorry I usually just purchase a cheap prepaid phone whenever I travel abroad but would love to be able to use my htc here in Lima. I appreciate the help.

Thats the thing though how do I know if it is carrier unlocked
All I've done to this phone is get s-off with revolutionary and root it.

if you bought it branded from say virgin, it will most likely be locked so only their sim cards work in it. if you buy a cheap sim card and put it in it will say enter unlock code or some ****. that means its locked. usually carriers (australia anyway) say if you have recharged more then 80 dollars or been with them for like 6 months they can unlock it for free.

First I would check with Virgin Mobile and see if they will give you an unlock code. If not, then you would need to visit one of the pay for sites and purchase an unlock code.

[Q] How do I unlock phone? Already have a code in-hand

So I have an i897 Captivate here. I've called AT&T and they gave me an unlock code for it.
I also have a new, never used AT&T SIM card installed in the phone.
I want to unlock the phone and hand it to my girlfriend so she has as few problems as possible when she goes to put the phone on a pre-paid plan of her choosing (I have no idea which it will be).
And I have installed a rooted Froyo ROM.
So how do I unlock it? All the guides I've found say I need to either be connected to a data plan already, or have a non-AT&T SIM installed. Neither of which are possible at the moment.
Any suggestions are appreciated.

Well, the only thing that comes to mind is to ask a friend to give you his/her non-AT&T SIM card for 2min.

Insert a sim and it will ask u for a unlock code

[Q] Found damaged N910T - Unlock, Root for Rom and Modem for ATT? [w/Pics]

My nephew said he found the phone on the road underneath an overpass. Screen digitizer looks damaged, no battery, no battery back cover and all banged up (see pics). He gave it to me to either fix or trash. I would like to get the phone looking new, working and give it back to my nephew running on AT&T's network.
Questions:
1. All the parts I need are compatible with most Note 4's correct? Will these work here and here?
2. Being a T-Mo device, the bootloader should be unlocked correct?
3. If the device is locked (not purchased by cash) can the unlock code be unnecessary by rooting? If not, what are my options since I did not purchase this device?
4. AT&T Roms are not compatible on T-Mo devices running on AT&T network correct? So will T-Mo Rom's work on N910T running on AT&T network?
5. Can I Root, flash Rom and modem?
Greatly appreciate your input, thanks.

Tmobile phone will work fine on AT&T. No need to flash anything special just pic a ROM and set up am APN.

I just purchased the T-Mobile variant and I am going to unlock it via http://www.cellunlocker.net. When checking out at cellunlocker.net they displayed a message:
"Please be advised in order to unlock your Samsung Note 4, you MUST activate the phone with the original carrier or SIM issued within your designated location. This must occur before you attempt to unlock and activate the phone with a foreign sim card. The Note 4 has a region lock feature seperate to sim unlocking and if unlocked before activating to its original carrier or continent the phone will be region-locked and must be unlocked directly from Samsung. For more information, please refer to the warning sticker found on the packaging that your phone came in."
Do I just need to get a T-Mobile sim and activate it once? Then boot it up with my ATT sim and enter in the unlock code? Or can I disregard this message?

You can disregard the statement it only applies to FOREIGN sim cards.

For activating the phone, I can use any imei correct? However, for unlocking it, I'd I have to, that could be the problem right?

If blacklisted network will refuse to connect to that phone even with active Sim card

1) not sure... most of the main parts should be the same.. i.e screen. There may be slight variations with many parts.. such as charging ports.
2)Bootloader is unlocked to my knowledge however Im not certain.
3) Rooting and unlocking are 2 seperate things. The phone will be carrier locked. I have a tmobile Note 4 phone that I run on AT&T. I paid to unlock it on simunlocker. Ive never rooted this phone yet
4)False to my knowledge. There should be no issue at all here
5)YOU cant change the modem to a modem from a different carrier. and there is absolutely no reason to do so. YOu should be able to flash an ATT rom on it if you'd like.
Unfortunately... It is true what others have said. If the phone was not paid for in full by the OG owner( on Tmobiles plan where you pay for the phone month to month)... then it will most likely be black listed at some point. SO you might be able to activate it but 4 months down the road it could suddenly stop working.

This is regardless of paying for an unlock correct? Any way of finding out if the IMEI is blacklisted?

Tmobile has an IMEI checker. Also swappa.com where you can sell/buy used phones has one. I checked mine before using cellunlocker and it worked out perfectly.

Yep, blacklisted.. Now what are my options, if any?

If it's blacklisted, nothing short of changing the IMEI # with a JTAG device can save it.
Considering it's physical condition, trash it. I would.

Looks baaaad. Ouch

After $200 in parts that I received yesterday, she looks beautiful now . I much rather work on it until its fully operational instead of trashing it.
None the less, still blacklisted and unable to access engineering mode. Any pointers?
Update: Running rooted 5.0.1 with TWRP recovery and have successfully unlocked via imei-unlocker.com. Made a call to a business number, worked fine.
Leads be to believe down the road a few months service may be cut off due to blacklist? I would still like to explore other alternatives to avoid service being possible cut off...
