how will I know if my phone is locked to a network?will a message come out after putting in another sim? I have a problem with my tytn II,my current sim card works with my phone but when I put in another sim,it does not recognize the sim. No message whatsoever appears on the screen but then there's no signal appearing on the signal bar as well as the name of the operator.

Sounds to me that you are locked to a single carrier. Just unlock your phone (search the Wiki - start in my sig). Your carrier won't notice this unless you need to send your phone in for warranty repairs - but there are also ways round that.
I turned my diamond off and attempted to turn it back on. It went to a screen I've never seen before. It said 'security unlocked' at the top. It was a multicolored screen with writing I didn't really read that much. What's going on with my phone?
I might need to take it back to Sprint and get a new one.
Security Unlocked basically means that all the restrictions have been removed from your phone in that you would be able to install anything on your phone..
• not the same thing as sim unlock which enables one to connect to any compatible telecommunications provider
This phone came like this out of the box are did you buy this from someone who unlocked this for you?
You're at the bootloader, its a screen where you can hard reset, flash new roms, etc.
Just soft-reset and you should be fine.
I was wondering what the breakdown of the method for changing the lock screen and notification menu that says at&t to something of my choosing. I am using a mac and would like to know the steps to do this. I know there is a thread for the HTC EVO, but i do not believe that to work for the captivate. Anyones help would be greatly appreciated.
You mean the one that says "no service" when you switch the phone on?
Could this data be received from the service provider itself?
Perhaps not; I bet it can be modded.
Nope, I mean where it says AT&T when you first wake the phone before you slide to unlock the phone, and where the AT&T is when you pull down the notification menu.
I can do screen shots if this still doesn't make sense, just let me know...
*** SOLUTION ***
Thank cellzealot for reiterating how to bypass the initial device/account setup wizard, as well as his and a few others' findings with the RadioComm tweaking.
All I had to do was pop my homemade Bell microSIM I cut out from my old fullsize one in, complete the steps outlined for the RadioComm patch and the four corner touch trick to bypass the setup wizard.
(Starting in the upper left corner, simply touch all four corners of the visible screen in a clockwise rotation, ie: upper left, upper right, lower right then lower left).

Hey all, just got my D4 in the mail today and have been trying to get the GSM functionality working for a few hours. I live in Canada, bought it used from eBay and so I don't have a Verizon account, nor do I have access to anyone with one.
I had no trouble at all using RadioComm to change the 8-byte string as per the threads on this and a few other forums, but I'm still getting the "This SIM card is from an unknown source" pop-up when I click the Android to begin the initial setup of the phone... and there is no way I can find around it.
I can see the signal bars now that I have a micro SIM that I've activated with my carrier (Bell Mobility) inserted into the microSIM slot in the back of the phone, but it still doesn't want to let me boot up. The only options in the pop-up telling me about the Unknown SIM are either Emergency Call or Power Off.
Anybody have any ideas? I've tried flashing up to the 219 fastboot as well with no luck, and of course applied the RadioComm edit immediately afterwards. I have a feeling that the phone only needs to be initially setup and then I'd be able to boot it up, because as I mentioned I can see that it's getting a signal but doesn't want to let me get into the initial user setup.
(And no, I'm not a n00b. Check the Droid 3 forum... )
Forgot to mention that the eBay seller didn't include their SIM so I don't have a Verizon micro SIM card, unfortunately for me. I have a ****ty feeling that I need to have one in just for the initial device setup then I'd be able to swap it out.
Argh!
You don't need a SIM to go through the setup process. Try it without a SIM. When you've completed the process reboot with the SIM and try to change the network manually. The SIM is unknown pop-up won't go away, I can tell you that much. When I was on 215, 219 and even AOSP/AOKP the pop-up came as soon as I entered my PIN. So don't worry about that. Sometimes it took a few minutes to get a signal. Recheck with RadioComm.
I had Safestrap on my system and that worked immediately. But the non safe system would not connect. Only after a couple of days. I can't remember if this is because I modified my build.prop.
If you're willing, you could try the ICS leak. I applied it and am very happy with it. It has settings for CDMA/GSM/World. Worked right away (had to setup APN). As you may have read, updating COULD take you off the official update path. But for me it was worth it.
It won't go anywhere but the screen that says "SIM Unknown"; the only two options it provides are two buttons on the bottom of the gray screen with the aforementioned message to either go into Emergency Dialer or Power Off. It's really frustrating! If I could just get past the setup part, I know this will work.
I can see the signal bars and can receive calls and receive texts (as well as reply to them, but I can't initiate them).
It also says Bell in the notification bar.
I am pretty tempted to do what you suggested and was debating it earlier, but haven't been able to get a concrete answer: has anyone tried to flash back to .215/.219 after applying the leaked update?
Yes and you will softbrick your phone! After updating to ICS the will phone run on a new kernel. Flashing SBF with an older kernel won't work.
The only thing I can think of is boot without SIM. Then edit your build.prop (you will need root). And hope now you can click "OK" at the bottom of the Unknown SIM pop-up.
Try chaning this in build.prop, reboot and check if you're able to click OK when the pop-up appears:
ro.default_usb_mode=2
persist.ril.modem.mode=2
ro.mot.phonemode.vzwglobalphone=1
ro.telephony.gsm-routes-us-smsc=0
These are the values I changed (apart from increase heap and wifi timing). Hopefully now you can click on OK so the screen goes away.
That's the problem, though, I can't edit any files or change anything because I can't get past the setup screen. I appreciate the help though!
I've tried without a SIM inserted and it just says it needs to have one, then prompts me to either Power Off or Emergency Dial, just like the other message about the Unknown SIM.
At any point in time did you ever have a Verizon SIM card inserted in your phone? I'm really perplexed about this one.
I don't think I'm going to try flashing the ICS leak just yet, just in case. Especially if it's not presently rootable.
I'm sure I'm not the only person this has or will happen to, I bought the phone from an American owner on eBay but I live in Canada and have inserted a Canadian GSM/UMTS carrier's SIM inside.
Nobody from Canada, either with Telus, Rogers or Bell with a D4 out there that managed to get it working?
Well, I plugged away at it long enough and finally managed to get past the initial setup screen, at least into the Settings menu so I could enable adb and installing unknown apps. That's all I needed...
Eventually a Smart Actions notification popped up and actually allowed me to set up a Smart Action without going through the setup, so I just made one that inevitably let me into the Settings menu and that was all she wrote.
Weird that this was happening though. I clearly have the GSM functions working as I can make and receive calls, but the phone is acting as if it is still locked and doesn't want to operate with a non-Verizon SIM.
I'm running .219, in case anyone was wondering.
But now you're passed the screen right? So why not root and try editing the build.prop. Like I wrote, this is all I edited and was able to use the phone with and without a SIM in it.
I did have a Verizon SIM, but I took it out at some point, before I had GSM working! It took me some days to get GSM working on 215 and 219. Wouldn't work without the edited build.prop! If you're afraid of testing, install safeboot. Then flash 215, update to 219 and use that one for testing.
You can bypass the initial setup screen by touching the four corners of the screen going clockwise starting at the top left. That will allow you to use the phone normally after that, but the unknown SIM error will persist.

I knew I remember hearing that somewhere. You sir, are a lifesaver. My previously mentioned workaround was okay but this is significantly easier. Especially considering I bootlooped my phone tinkering with build.prop settings and wasn't able to luck out and get that Smart Actions popup while stuck at the initial setup screen.
Thanks a million for your help!
(You too, Die Bruine. Trust me, I'm not afraid of making build.prop tweaks, I've been at this game for a while... )
Hello,
Everytime that i restart my phone it shows a warning icon on the notification bar, saying No Service, then i press on it and it puts me in Network Operators, then i need to pick one from the list and it works, but everytime i pick the same one and it always resets after format, what is going on?
Edit: i have tried a new simcard that got a pin code to it, and same thing, everytime that i restart the phone it is asking me to insert the pin code, how can i fix it ? i heard it got something to do with phone branding
