Hello, I bought a Blackberry Curve 9300 from a phone shop, it was working perfectly for about 3 months, I decided I was unhappy with my network provider and went to get the phone unlocked, the first guy used all 10 attempts and said he couldn't fix it, I then took it to a second shop run by Nokia and they ordered a new chip and MEP code and still it said the same thing, so I just got my phone back. When I done this, the guy in the shop told me that my phone would work on the previous Network Provider I used before (Tesco Mobile). I then got a new sim from the contract I currently had and decided to stay with them.
I put the Sim in my phone and it shows full network bars. However when I try to phone or text it says "Network Unavailable", I went into the service status and it reads:
Phone number: Unknown Number
Status: Not Available
Connection: Not Connected
The internet works and I'm not connected to wifi which means I know it isn't the sim, the phone should be fine and not blocked as I previously used it before with the same network provider, dose anyone know how to fix this ?

Hi and Welcome to the Community!
Your BB indeed now is permanently locked to the carrier for which it was originally manufactured. Contrary to what the second shop may have tried, that cannot be (legally) undone except at the BB factory. But, what they've all told you indeed should be true that it should remain usable on your original carrier. Why it's not working is strange indeed.
I recommend you do a complete device WIPE:
Make sure to select everything it offers. If you need to backup first, you can find full instructions via the link in my auto-sig on this post.
You must first get things working for voice-level services -- phone calls, voice mail, SMS, etc. Only after that will data be of any value to attempt to get working. If Tesco has a shop with qualified BB technicians, you may want to seek out their in-person help.
Good luck and let us know!
