Default Checking if phone is unlocked

Hey guys. I was just trying to check if my phone is locked or not but I can't seem to do it
I tried checking the status of my phone's network lock by going to dial pad and entering *# 7465625# Usually after you enter the last symbol (#), it should take you to the specified screen and tell you if your phone is carrier locked or not. However nothing is happening and if i press the call button it says "running USSD code" and says its and invalid code.

Any wisdom?

They removed that USSD code function at some point with one of their firmware updates. Don't you have a different SIM to try on it?

Right so it was bought as a locked phone and then (maybe) unlocked. I dunno tbh other than as sherlock says trying someones sim in it unless theres maybe an app that tells the lock status..

Thanks. The thing is all my other sim cards are bigger and I don't want to cut them down unless I am sure they can actually go in the phone! But yea I think it is actually locked.

No I got it with a contract and it was locked but I asked them to unlock it and it is taking them ages so I was wondering if there is a way to check if they have done it yet. They said they are going to contact me but I still haven't heard from them.

Unless its a US phone, try the GalaxSim Unlock app mate (free)
It claims to be able to unlock s3s but also tells you the lock status. Havent tried it but its worth a shot

Nope, without root it can't read the phone status, unfortunately.

The Provider can not unlock the phone OTA, the code has to be manually input on the device. Call back and request the Sim Unlock code. You will need a Sim from another Provider to get it to pop up the window to input the unlock code.

That's what they told me. Now i need to find a SIM card, the same size as mine, but from another carrier.LOL I have an old T-Mobile SIM card, but it's too big to fit into the slot.

What about CDMA phone? Are those strictly locked to one network as they do not have a sim slot? Just curious, I've never been to the US, so all these is pretty new to me.

Yes, CDMA phones in the us are tied to a carrier

Its possible to switch to some prepaid networks but its a legal grey area.

lol DONT attempt to do it without a proper sim cutter. Most lil phone shops will do it for free if youre friendly. Ive seen friends try to cut sims with a carpet knife or whatever and failing badly

The old Sim is too thick to fit into the slot. I think that i need a newer type of SIM card. My daughter uses T-Mobile, so if her Sim is the same size as mine, i'm good to go.

Nah the s3 uses a micro sim mate (same thickness as the older ones, just less wide and long. I got my old sim cut and it didnt take any thickness off)
I think its the Nano sims that are thinner n i think(?) Its only iphone5 that uses them
Maybe its different in US?

Must be. The card is much thicker, and if i try to jam it in, i'll screw it up.
