"This SIM card is from an unknown source"

I've looked around for similar thread(s) but found nothing. I recently followed the instructions on this website-> "teambamf.net/index.php/topic/3528-guide-to-install-ics-ruu-and-firmware-windows/" and got the phone started up. Unfortunately since I'm not Verizon (T-mobile USA) I've been stuck at the "Activating" screen for hours now and it keeps saying "SIM card from unknown source". Any help to fix either (if not both of these problems) will be greatly appreciated.
P.S - tried rebooting several times and still stuck at the Activation screen after SIM from unknown source.
did you try to boot the phone up first without sim card? The phone by default is locked to cdma and you would have to manually change to gsm in order for it to work.
Try to boot up without SIM (and also any SD card. I had issue that my sd card has a rom in it and it won't let me to get any network data, so I had to erase the SD card and it work. So start without the sd card). Then setup the phone. Once it's setup, change the network to GSM and then shut down and put hte sim. See if this works.
I would suggest check out this thread: http://forum.xda-developers.com/showthread.php?t=1421341
also, is your sim already activated? I am not too sure if you can use rezound ot activate any sim. if it is not activate, try to activate with a diff phone first and then put in the rezound afterwards.

get an app called App Disabler... it works great... just run the app and find the listing for verizons Setup Wizard... disable that app and you'll be good to go...

If you have Verizon and a Verizon branded phone and are getting this message, you need to contact customer support.

Have you tried this solution: http://forum.xda-developers.com/showthread.php?t=1882355
Otherwise, the Business Sense ROM is based on stock, and this will happen on all stock ROMs, but it should not effect actually using the device... It would be best to move to a CM or AOSP based ROM.

No Sim Card Detected Problem

After troubleshooting the phone for bootloop problem,
I just successfully flashed the KingCobra3D-ICS-1.6.zip ROM in my HTC EVO 3D GSM S-ON phone.
When it rebooted, the sim card is not detected yet the phone fuctions the same the apps are working etc..
excpet for the sim card detection part (messages, phone, nothing there)
Also there are no language when it was reseted no English (Philippines) that's why I wondered..
The Sim Card is not broken or damaged, I tried inserting it on other phones and also it functions normally..
I tried inserting other sim card on the phone yet it still wont detect it. there are no problem in terms of placing it..
Also the location problem its stuck in US there are no philippine area
How can I resolve this problem by making this sim card be detected again? Thank you for the help

Seems like an odd problem. I would just to reflash the rom. Its possible when you downloaded the rom it got corrupted also. Maybe redownload it and then reflash it. worth a try.
