Need a quick answer regarding SIM cards

Hey guys, I'm new to the G1. I just picked a used one up the other day to use over seas. I reset the phone not knowing I need a SIM in there to actually use it. I don't have access to a SIM card currently, but I will have one when I go over seas. Will the phone unlock so I can root it with a SIM card from a different carrier? Or do I need to have a TMobile one in there? My plan leaves tomorrow early morning, so I'm kind of in a bind when it comes to solving my phone issues.

Removed...

Oops, I thought I posted in General.

The sim card from n e where will work for the rooting process so don't stress that. These instructions will get u n to the phone with out the sim card. http://theunlockr.com/2010/01/10/how-to-activate-the-g1-without-a-data-plan-or-sim-card/

Good luck!

If the phone is locked , you need to get it unlocked first....otherwise it wont use any other network sim other than t-mobile.
The easiest way to unlock it is to call t-mobile and ask them for unlock code by giving them IMEI number of the phone (can be found in the MENU--->SETTINGS---->ABOUT PHONE----->IMEI NUMBER)
They provide the unlock code for free.
Once you have it unlocked, then whatever sim you insert, you will be asked to enter the unlock code. Enter that code and phone will start using that sim.
If you dont get it unlocked here from T-mobile then get it unlocked from the country where you are going...but the charges and success rate of unlocking depends on which country you are going to.....it is very easy and cheap in South Asia like India and Pakistan.....but difficult in Middle East.....
So the best alternative might be to buy a cheap GSM phone there and sell it when you return here.
Have a happy and safe journey

Thanks for the help everyone. Unfortunately, Tmobile couldn't give me an unlock code since I'm not their customer. I've got some more digging to do. I came across some sites offering the code for a fee, are they legit? I just don't understand how they get the code when I can't.

Go to ebay and buy it. for abt $6.49, they will give the code to you. I unlocked mine via ebay... Try any seller.
Based on timezone, buy from US seller or your local seller to get it quick.
Like for US try http://cgi.ebay.com/UNLOCK-CODE-T-M...025?pt=LH_DefaultDomain_0&hash=item1e5f205f99
Make sure u provide them your IMEI code.. dial *#06# Or look under battery.

Has anyone figured out how to unlock there Gs6

I just bought an unlock code I'll need during a trip for $9. Can't get much better than that. (haven't tested it yet)
It could be months before someone releases a free method.

First person fell through and refunded.
Ended up getting one from Ebay for $12. Confirmed code working now.
Depending on your carrier, the prices may differ.

Where did you buy it? Can you tell me? I want to buy too..

If you're up for it, flashing Metro pcs firmware onto Tmobile variant is said to work. When unlocked, you can flash back onto the Tmobile firmware. I'm not brave enough to try...I have 14 days left so I can unlock

Just do a search on Ebay for..
"Galaxy S6 unlock code" and your carrier
The auction was for my carrier.
You'll have to find yours.

you need to flash it to metropcs firmware, then request the unlockcode, i use cellunlocker.net, use all usa carriers because if you request for t-mobile it going to say not elegible to unlock. once you got the code, follow this:
1: power off your device
2: put a non accepted sim
3: turn on your device
4: put it the unlock code
once you got unlocked don't flash again to t-mobile because it gonna blocked again.
hope this help you.

Yesterday I unlocked my phone using network unlock code. I got it from Getunlocked.com. Their service is fast and they provide me the unlock code and unfreeze code. Before approaching them I tried two different providers but they couldnt able to find out the unlock code for me.
The process is simple
1. Put a new sim Card
2. Switch on the phone
3. It will ask you for network unlock code
Enter network unlock code
4. Will give you a message network unlock successful
* If that doesnt work then you may need unfreeze code
1) Restart the phone with the new SIM Card inserted
2) You should be prompted for an unlock code
3) Enter this DEFREEZE code: xxxxxxxx and press unlock
4) The phone will display “Network Unlock Request Unsuccessful”
5) Enter the NETWORK Code: XXXXXXXX and press unlock
6) Phone should display “Network Unlock Successful”

[Q] So I have an unlockable phone...

Hi guys.
I won a phone from Samsung in a event they were hosting in downtown toronto. It took them a while but I finally got the phone!!!
Unfortunately its locked to a network im not a customer with - Im on contract with another.
I've paid 3 seperate websites (Canada GSM, Cellunlocker.net, and Unlock Genius) but nobody can find the IMEI in their database! I paid the carrier its locked with - but even they couldnt find it!!!
Do i have a ghost phone? Is there anyway to unlock it other than the unlock code?
Thanks.

try http://www.fastgsm.com/en

Thanks Tomerbi for the advice, but I doubt they'll be able to find it considering 3 other websites couldnt (Paypal is having a field day, freezing the refunds as they come in).

What's the model number of the phone? For example mine is an international unlocked SM-G920F. Perhaps there is a region lock on it? The unlock sites can't do anything about that.

SM-G920W8 - Im using a sim from the appropriate region of the world, and briefly used a sim from the network it is locked to!

Looks like its a Canadian phone. And you're using it in Canada. Strange.
And when you put in the sim card for the network it is locked to that doesn't work either? Then what network were they expecting you to use it on when they gave it to you?

Its locked to Telus - Telus connections do work in the phone. Only type that do work. Just that nothing else does, and Telus doesnt have the IMEI in their database.

SIM unlock?

Please post experience with S7 SIM (carrier) unlocking here, specifically third party websites that offer an unlocking service.

I bought my phone out right from T-mobile. And their unlock app that comes on the phone does not work

It works but you have to know what you're doing with it. Did you contact Tmobile for unlock code. We unlock and blacklist repair the Sprint, Tmobile, etc. The Tmobile ones have to go through that app during the process

yea man i called...they sent an email with instructions.. email stated this phone doesn't require an unlock code as it has a built in unlock app. follow the directions below blah blah balh
bottom line, it doesn't work. why? because there's hidden rules and crap that need to be met 1st by t-mobile. prepaid people need to spend at least 100 dollars in refills before the phone is eligible. post paid people need to have the phone active on t-mobile for a minimum of 45 days and your account cannot be cancelled during that time.
well seeing as how i'm on prepaid... i walked in, made a new customer purchase as a post paid user, then cancelled my line after i got my gear vr and netflix code... which wasn't even 30 days. I can't unlock my phone, So I'm now on prepaid gonna see if I can after 100 dollars in refills

I use ebay to get my unlock codes, unlocked maybe a dozen phones in the last few years and never had any issues with anyone.

A couple reliable sites I've used many times are www.unlockbase.com and www.cellunlocker.net . There's also a thread over on the s6 general forum of a member named stifilz that can unlock your device via USB cable, his service is free but a donation is always a nice gesture. Good luck!

kinda ridiculous you have to pay to get an unlock code still. My SM-G930FD i bought unlocked locks itself every time in install a T-mobile csc and the app wont even run on that phone

Hi can anyone help? I bought an At&t S7 Edge on amazon and got the unlock code from the vendor and it apparently worked. My only issue is that it'll only work with the sim that was in the phone when I entered the code. If I use another one the phone keeps displaying "insert sim". Thanks already for your replies

Thanks for the reply and there's 1 more things I need to mention: I'm using the phone overseas (Haiti) as it's still under At&t contract. Now to answer your questions no it doesn't ask for the unlock code anymore but like I said it only works with the non At&t
sim I used when entering the unlock code.

s7 (sm-930f) lock to Austrian A1 was not able to be unlocked by unlockbase.com. However, the nck from cellunlocker.net worked well.

Ok so what im mentioning is something im still not getting quite well, but i saw before many samsung phones S6, S7, Note... etc that have the international firmware 9XXF/FD even when the phone is actually a T-Mobile version or AT&T, in download mode you will be shown the real phone model but the firmware isn't. Of course through Odin with a PC you won't be able to flash the phone with a firmware besides the one designed for it. If you actually wanna flash the phone you'll need the original firmware, i tried it before and flashed a Verizon S6 that had the international 6.0 firmware on it through Odin and as you might guess i got an error as the device didn't match the firmware, when i actually flashed it with the correct Verizon 7.0 firmware it worked and the phone booted and worked alright, except that now the phone is network locked! downgrade isn't possible unless i use a repair firmware and a pit file (not sure if still works with nougat). Then i got the idea of actually using the repair firmware and the pit of the 9XXF version as its network free, and ended up breaking the phone completely. The jig didn't work so couldn't access odin. So i work for a friend of mine in a repair workshop PC, Consoles, Mobiles... blablabla and we have the Z3x box, it did unbrick the phone, and then i started playing with it to see what it can do, and there is an option to actually flash and mix different parts of the firmware, so i went an flashed the bootloader of the Verizon firmware with the rest from the international firmware, it didn't boot at first but somehow i got it into recovery mode and after a format it did boot, and the network was actually unlocked after.
I do not think this method would work on all versions, as some samsung phones uses the snapdragon soc while others uses the exynos soc, and i don't think you can mix those firmwares, but an unlocked exynos model might be unlockable with the international firmware, of course considering the risk of breaking the phone, but if you're lucky as i was and have one of those boxes you shouldn't be much afraid.
Something else i'd like to mention, is that the Z3x can actually fully backup the phone, and i don't mean a nandroid backup like TWRP but like a full partitions backup, and the idea i got but didn't test is if you have for example a locked S7 and an unlocked one and same model so let's say 930P, you can actually copy the raw partitions from the unlocked one to the locked one and i don't know, maybe ending up unlocking it too, again didn't test this one as i only have one S7 and its already unlocked (930FD).

SIM unlock S+

Hi,
Looking in this forum but can't see how to SIM unlock my S+. Phone was locked so I re-flashed with Odin but can't find guide to unlock SIM.
Phone is locked to UK Vodafone.
Can you send me please guide if there is some? Thanks

What is the message your phone displays when you insert a SIM card other than Vodafone UK (ie, a non-accepted SIM card) and try to place a phone call?
If the phone is locked, it will ask you for unlocking codes.

Yes, it's asking for unlock code. I could fix this with odin and some flash on my S7 Edge but how can I do this on S8+?

As far as I know you should buy the unlock code on eBay. Actually it depends on operator (each operator has its own way to lock it). For example Verizon doesn't lock GSM part on the modem for their phones at all. Sometimes remote unlock procedure is required (you will pay to third party and they will do it through the Teamview). The price depends on operator. There are 99% that you will not do it for free by yourself.
There is one chance to do it yourself only if your provider made some calling time lock. For example you have to insert Vodafone SIM card and make a phone call for some 5-10 minutes (but it shlould be done inside the country of phone's origin, UK in your case). Try to ask someone with a same Vodafone UK phone.
You can do it with Odin only if it was not really locked from the beginning but just had some carriers bloat, that was asking for that unlock.
What is exact model of your S8+? What does it says in Bootloader mode?

But actually I could do this with S7 edge. So S8 has some protection?

Based on other operators experience I would say you cannot do it by yourself as usually simple flashing will not unlock the phone. You will really need one of paid methods to unlock it. It is still better to ask someone with a same Vodafone phone. As unlockers on ebay etc. make money with those methods I don't really believe that someone here will tell you how to do that by your own.
There was a thread where the guy was discussing unlock for his Austrian locked phone. Finally he paid twice as first seller sold him some wrong unlock code and phone became network blocked completely. However he bought some "unfreeze" code from different seller and that worked for him. If it would be so easy to unlock operators phones they will never sell them cheaper than unlocked.
Another option is still to perform call with original Verizon UK SIM card for 10 minutes. After that you should reboot your phone and it should be unlocked. If it will not work you can approach Vodafone UK and ask them for unlock code. If there was no any financial issues for that phone and it is registered more than 6 months in the network they should provide you with unlock code for free.
Sorry if I didn't help you too much.
