[Q] [Help] Xperia S hardlock network?

Hi there,
I was decieved buying my xperia S from a french operator which was supposed to be free from network locks. Unfortunately it seems not. I'm currently travelling abroad for a few months and i logically bought a local plan with a new SIM. When i inserted the sim in my xperia s, I was asked for a code. Since i believed my phone was unlocked i'm afraid i entered the wrong pin a few times...
Then i asked the company from which i bought the phone to give me the unlock network code. They did, but the number has no effect. I am still asked for PIN network code when i reboot the phone. After looking it up on the net i found that my phone was probably hardlocked. Here's what i found in my phone menu after typing *#*#7378423#*#* :
[X] Network 0
[ ] Network Subset 0
[ ] Service Provider 0
[ ] Corporate 0
[ ] Sim 0
Where should i go grom there? Is there any chance i can use my phone with a different phone operator? (my phone is still working with my french SIM) Can i still hope to unlock the network?
Thx for your help.

Since your phone is still working with your french sim card, my guess is that the other sim card you bought got locked since you entered the wrong pin number too many times. Getting an unlock network code from the operator doesnt change/remove the sim lock as it only removes the network lock off the phone so that you can use it with other operators/providers.
Try getting a new sim card (from the same operator you bought the other one from) and see if it works.

But the new SIM card I inserted had no PIN code activated. How could i PIN lock my phone ?
Edit: the PIN code i was talking about earlier was the Network PIN code when i inserted the new SIM card. I'm afraid i locked this one up

APN issues won't cause the phone fail to recognize a SIM card. The issue is probably hardware or ROM. Which ROM are you running?. Is there a notification that there is not a SIM card present or are you just not able to connect to a cellular network?

Edit your post and pull the imei out. Right now. Posting it is dangerous.

I plugged your imei into the tmobile imei check search. Your device was reported as blocked. It will not work on any GSM network in the USA as it I'd considered lost/stolen.
