[Q] How can I check if my device is locked?

---

I want to check if my sgt 7.7 is in fact locked. I've tried all the possible secret codes for the galaxy tab 7, but they do not work for the 7.7 When I put my sim card in the device it will not connect to the network I need.

Every time is says "your sim card does not allow a connection to this network"

I don't know anyone I can switch sim cards with so I could test. I am a foreigner in Korea. Thanks for the help

How can thw Tab be locket when it'a not available at any network provider yet? Maybe just your SIM is broken... Did you ty he card in a diferent device or a different SIM in your Tab?

Sent from my GT-P6800 using XDA App

Which band and protocols does you P6800 support?, look on the box if it says GSM, WCDMA, CDMA etc... if your network provider does not support the bands and protocols avalible in you P6800 you might need to find another subscription.

Well it says your sim card not your Device so the prob is on your sim card
