Sim card unlocker

---

Hi,
I would like to know where can I buy a sim card unlocker. (I know I can introduce a code to unlock the device but I´ll lost waranty)

Thank you!

As far as im concerned its impossible without a code and without voiding your warrenty. There might be something but im still a n00b with unlocking so maybe another samsung device will have an app for it like the s2/3.

It's codes-only on Samsung devices. Even if you pull the code from the phone itself like with the S1, S2 etc. you still need to manually input the code.

The only thing I can think of that resembles a hardware unlocker is the XTC Clip, which is for HTC devices only. Perhaps a JTAG box like a Riff will do it? You'd need to read up.

SIM unlocking generally doesn't void a handset warranty, flashing ROMs and Recoveries however, does

I don't know where your from OP, but if you're from anywhere in the EU, your phone carrier is legally obliged by EU law to allow you unlock your phone from their network.

There may be a certain length of time from when you purchased the phone/started the phone contract (here in Ireland I think it's 90 days, at least for PAYG phones).

You just have to ring up your carriers customer support and they should give you the unlock code (and possibly how to enter the code), once you've verified you're the owner of the phone/contract.

Hope this helps
