I bought my amazon fire phone with the full price (no contract). After I registered the phone and activate my number. I couldn’t get a reception. It look like the international roaming is not working.
Later on i replaced the att sim with one with the local sim card company in Kuwait since at the moment am not in the state.
Now the phone it shows a mesg with INVALID SIM. Why is that???
atry to call att and amazon, but unfortunately no solution yet and I am stuck with this phone aboard.

If you enter the code too many times wrong, it permanently locks the SIM and it will need to be replaced.

You are correct, if you enter the Network Lock code incorrectly too many times, the phone will be permanently locked and there will be no way to try to unlock it in the future. A SIM card pin entered incorrectly, will lock the SIM, which can be replaced, but if the phone Network Lock is permanent, there is no way to go back.
If you're not planning on using this phone with AT&T, you should try to return it as soon as possible, as at this time it's AT&T exclusive and will not be unlocked. You should wait for the unlocked version.

I have been having this same problem on my new phone just found this post this morning on the amazon site from Feburary. It seems to be the answer. Thank you Rebecca! Why couldn't the Amazon people figure it out? All their answers seemed to put it on the customer or phone companies back. Not good protocol. Nonetheless, here's the solution.
"I emailed Amazon about this same situation on my Kindle HDX AT&T device today. The problem is most likely NOT with the hardware or the SIM, but with the Kindle software network wake/sleep feature. When you read Kindle books for a long period or the device is not in use, it appears all network capability controlled by the Kindle software/firmware goes to sleep to conserve battery life. The software "wake" feature for Wifi (like your home broadband wireless) and for your mobile (Verizon/AT&T) network doesn't work reliably, since it's either slow to activate or doesn't activate entirely. In order for the device to "wake up" for any networking when you have the invalid SIM and/or a dead wifi network connection (ie, wifi appears to be "connected" but you can't get any content to load in SILK or your Facebook app), you often have to reboot the device to regain any network connectivity either way. "
Amazon's software developers need to fix this - as another poster stated, the long term solution shouldn't be to shut down and restart the device. That's just poorly executed code.
