[Q] VZW i535 on KOODO

Hi,
I'd like to have some help. I bought a Verizon Samsung galaxy S3 ( SCH-I535 ) unlocked for Verizon, Rogers and Chatr. Since I have it, I'm reading and trying some things (root, flash rom, etc.), but I can't get it working on Koodo(Canada) with the SIM card I had. I readed stuff about GSM network on global mode but it didn't work for me ( Maybe I did something wrong..)
I would need help for this

Hmm ... and you are sure it's unlocked?
After flashing a stock ROM, it may be locked again.
Ok, if it's unlocked, please check this All-in-One thread for your device first.
There you will find links to modem/radio threads.
What you described is usually caused by a locked phone or a "bad" modem/radio.
So flashing another modem may help ... if the phone is unlocked.
And if you have further questions about this device, you can ask in the general help thread.
EDIT:
Just in case you are not sure if it's unlocked, check this thread about how to unlock your device.

Note Edge Hand Free Activation Help India

Hi, today i bought a note edge for cheap from a shopkeeper the condition is awesome, but the issue is that when i got home i reset the device and after that when i entered my Indian GSM Sim into that the phone stuck at a screen saying Hands Free Activation, after a bit of research i got to know the phone is not Indian. So Now the phone has booted up but it says SM- N915P Instead Of N915G(Indian) i am getting Proper Signals but the options i have on my sister's note edge are diffrent However both phones have the same OS 6.1 Marshmellow.
What I Think is that the Phone is unlocked and what i want to ask is if i flash N915G Firmware Official, will my phone still be usable? Will I Get Proper Signals 2G,3G and LTE? and if the phone again gets locked how will i unlock it??
Details Of the Phone :
BASEBAND Version : N915PVPU4DPF3
MODEL: SM-915P (Not Indian)
No Option To only switch to 2G,3G or LTE like My sis's Note Edge.
Please Help. Any Help Will Be Appreciated.
