    Hi everybody,

    I have a brand new white iPhone 4S and I've encountered some strange problems... it started that I couldn't send SMS and then my iPhone kept losing the network and at some point it just showed "No Service" all the time anymore.

    By chance I found out that all those problems are solved if I just disable the PIN code. Now, without PIN, it works 100%.

    I don't really care about having a PIN or not, but I'm still a bit concerned if something is wrong with my phone. Does anybody have the same issue? Is it rather a hardware or software problem?

    And do you think it's worth to get a replacement phone?

    Thanks for your help!

    Hi Nefa,
    My phone is having no problems with locked sim card. It must be something with your phone specificaly. All I can think of is - get another phone from Apple!
