You can't simple change your sim card to another phone, your lg phone must be unlocked first. To unlock lg neon gt365 you must have lg unlock code for your lg phone network carrier. This code can be purchased at third party sites for small price and you can do unlocking by your self since you also get details instruction how to unlock your phone.

I bought a unlock code for my lg gt365 neon and i put a tracfone sim card in it and it says emergency calls only how do i fix it so i can use a tracfone sim card.


First you need to unlock your phone before you put tracfone sim card on that phone. Make sure you have appropriate LG neon GT365 unlock code example : if your old sim card using t-mobile you must use t-mobile unlock code for your phone not tracfone. You can get lg unlock code from online seller with lower price and quick turnaround.

How do i find the puk code on my lg neon phone


Hi there, it is printed on the voucher of the sim card when you have purcchased it, and it is related to sim and not with the phone..PUK means "Personal Unlocking Key" and it is asked if you enter wrong pin for three times. You are then given 10 attempts to enter the PUK. Your sim card will be blocked permanently if you still entered incorrect PUK code after the 10th attempt.
And if ever you lost the voucher you have only 2 ways to get rid of the PUK code:
1. Replace the sim card or 2. Call the phone company that released the sim card. They will give you the PUK code once you give them your account details and they have confirmed your identity.
Hope this can help you,GoodLuck=)

It's normal since your phone still locked. You must unlock your phone first with lg neon unlock code for your phone network carrier. This code will reset your phone network to default factory setting so you can put any sim card on that phone. Lg unlock code can be purchased at third party sites on internet.
