SIM Card Inserted Locked

[alicehung93]

I have an unlocked Samsung Galaxy S5 Neo. I just transferred and activated my Public Mobile accound. I tried to use the new SIM card in the phone but "Invalid SIM card. Network locked SIM card inserted". How do I fix it?

@alicehung93 you have to call your previous provider and have them unlocked the phone!  Who were you with before?

@alicehung93 hi yes that does mean your phone is locked to your previous carrier as suggested by @GR

@alicehung93  also because it's a Samsung you can go on samsung.ca and start a chat conversation and ask them for the unlock code!

I've called them and they gave me numbers to unlock but it's still locked

@alicehung93  make sure you input it exactly as given. If it doesn't work call them back. If you input it wrong too many times then you need a master code from Samsung
