[Q] Xt910 Network (SIM) Unlocked? - Motorola Droid RAZR

Hi there guys, i have quite a peculiar problem and i tried searching the threads but to no avail.
I have an international RAZR XT910, i got it used, and as far as I know, it is sim unlocked, because i am already using a local sim on it (i live in the Philippines btw) and no local carrier offers this phone, thus the assumption that it is already sim unlocked.
However earlier today, when i tried to pop in another local carrier's sim card, i cant get any signal, and i dont even get the "sim card invalid" screen, just won't get signal at all.
I know the sim card is good since i tried using 2 different ones, but both wont get a signal.
When i put back my original sim card the phone works normal and gets signal.
My question really is, how do i make sure the phone is unlocked? Coz i know with samsungs there are codes you can use.
I have stock ics on system 1 and PA3.8 on system 2 using BMM btw, if that matters.
Hope to get a response. Thanks guys.

How old is that second sim card?
I've had that problem when I bought this phone,my sim was10 years old,it was functional in some older phones but not in this one,because of old chip,so I had to replace it with new one.

That's what i thought, so i bought a new one, (hence 2 SIMs) still same issue, no signal.
I'm thinking, is it possible that phone may not be completely unlocked?

Never heard of it, my thoughts were same as welder73s... Any chance to try SIM from yet another carrier? =)

I just did, we have 3 carriers here in my country. I tried the other 2 and both have the same symptoms, no signal. :banghead:
I don't understand why this is fhe case, bexause i am sure that the carrier which works on the phone never released this phone, thus the phone being sim locked to this network is unlikely.
Isn't there a way to check the lock status of the phone?

So as a last ditch effort, i think i'll try reflashing completely to stock.
I am currently on ICS 4.0.4 on slot 1 BMM. Can anyone point me to a thread that xan teach me how to flash to stock correctly? Thanks guys.
