I got an orange sim card today via the post and I decided to try unlocking my Nokia 6230i phone.All went well till I found out theres no network coverage.If the network isnt down in my area what else can it be making my phone not have a signal ???? I hope someone can help me The Phone,my main sim card and the orange sim card are all from the UK and Im based in the UK. so it isnt a compatable issue
