Question Unlock has crippled All Networks

Hey guys, bit of a weird one. Got a Samsung Galaxy S3 Mini GT-I8190N on O2 which I went to unlock.
Got the unlock code and defreeze code and put in the unlock code which it said unsuccessful so used the defreeze code which then said successful.
Started the phone up with a Vodafone SIM and noticed it wasn't getting signal and just showing Emergency Calls Only.
Checked in Phone Status and I get the following:

On Vodafone SIM:
Network - Unknown
Mobile Nework Type - GPRS
Service state - Out of service
Roaming - Not roaming
Mobile network state - Disconnected
My phone number - 07554XXXXXX
IMEI - 35650XXXXXXXXXX
IMEI SV - 01
IP Address - Unavailable
Device status - Official

On O2 SIM:
Network - O2 UK
Mobile Nework Type - GPRS
Service state - Out of service
Roaming - Not roaming
Mobile network state - Disconnected
My phone number - 07564XXXXXX
IMEI - 35650XXXXXXXXXX
IMEI SV - 01
IP Address - Unavailable
Device status - Official

It looks like the Unlock was unsuccessful but it has not crippled the phone and I cant get it to connect with the original O2 SIM.

I've made sure Date and Time are correct and tried connecting with WIFI to see if it kicked in but no difference.

Any assitance would be much appreciatted!!

Thanks
