I have a Samsung GT - s3570. The problem is, when i insert a SIM card , the phone requires an unlock code. I tried different SIM cards but still same problem ... The phone works without SIM,I want to make it work with SIM CARD.
My question is: how can unlock the phone without going to a service? Financial situation does not allow me to send it to a service .If anyone has any ideas, please help me .

Richard
maybe it's SIMLOCK,try to unlock it :wink:
networks
ok the network what works fine are vodafone on contract and all other sim cards on all other networks keeps coming up with invalid or missing sim even if put a pay as you go vodafone sim card in. tried to unlock the phone using xdadev_all_unlock-v1.6_138 it says the phone is unlocked but still the same it has been upgraded to the lastest t-mobile NL_11300_131_11200 roms so please help
Suggestion
I suggest that you try locking it if it says it's unlock, before you re-unlock it and check it out that way!
take out ur battery, try pull all the sim pin one by one as they maybe not touching firmly.
Hi!
Anybody knows how to solve this problem? I'he got the same one.
Sim contacts are ok. It's software problem for sure.
Owner told me had tried to unlock it with LokwizMsl.bat in stead of xdadev_all_unlock-v1.6.
Regards,
I know that my vodafone sim works in my phone, but when i put an orange sim in it doesnt ask for an unlock code but simply shows no signal, Ive got a custom rom atm and all help is appreciated

Did you try inserting "a SIM card not attached to your current provider (e.g if you have T-mob use an ATT SIM CARD) and turn on your phone?" (credit sanfranx415 post) edit: maybe try a different gsm carrier in the same country you reside.
From what I have read and understand different versions of busybox will work or are compatible for different things (maybe somebody will tell me if that is not accurate).
Here is a video that might help.
Good luck!
Try contacting t mobile and tell them your going overseas for a few months and want to take your phone with you and is there a way to unlock it so it can be used in another country.

When you insert the sim card and power up the phone, as you unlock it it should give you a network lock screen that only lets you use the phone after inputting the unlock code.
hi guys i need a little help. i have a rooted samsung galaxy ace running cyanogen mod 9. i have used the galaxy unlock tool from play store to generate my sim unlock code, however when a put a unrecognised sim card in the phone the sim unlock code entry box fails to appear. it just goes to the normal home screen showing emergancy calls only, so i have no idea how to enter the code now. please help asap as i need to get up and running.
please note the phone is definately sim locked lol.
thanks in advance
Wipe all datas via CWM recovery or inser a sim of other carrier on your phone and then insert your sim in the phone

Hello, I got the phone from a week, but I managed to lock the second slot, and when I put a sim card in, it asks for network unlock sim code.
I know there are a lot ot threads here, but I didn't found something that works for this model. I can use ADB, Terminal, my phone is rooted, so if you give me a clues how to unlock it, I will be very grateful.
