I have a virgin mobile i9000 and i cant seem to get it working with my gsm telus sim card. any tips or advice?

Did you buy the phone unlocked?
If not I believe you would need to have the phone unlocked in order order to use a Telus SIM card in it.
Hey guys. I just received a T599n, which is the s3 mini on the metropcs network. My plan is T-Mobile and i wanted to know how I can unlock this phone to work with my T-Mobile sim card without paying or if it is possible to install an international rom on this device which will allow it to be unlocked, maybe? Sorry for being nooby.

According this http://forum.xda-developers.com/galaxy-s3/help-i9305/news-downgrade-android-4-3-to-4-1-2-t2644371 you can downgrade to 4.1 via Mobile Odin 3.85.apk

So I've found a HTC One M7 in the park about 2 weeks ago that was blocked on O2 - I live in England - so I bought a code and unlocked it to work on all the networks, however, it won't read the sim card even if I manually choose the network - it says that my sim card cannot be registered on that network and I'm also having no signal. So I thought that the person who lost it went to O2 and O2 blocked it. So, here comes my question - how can I unblock it so that it can read my SIM card, or, I don't know, register it? Thanks in advance! By the way, I unlocked it's Bootloader, I rooted it, and I installed a Custom Recovery, but I couldn't S-off it cause it is running HBOOT 1.61 with Stock Android Lollipop 5.0.2.
I flashed my sprint note 8 to a unlocked firmware, and it's using a tmobile sim.
After the news, I try to switch back. I flashed the firmware N950USQS2BQL9_N950UOYN2BQL9_SPR using ordin. But when the phone boots up, it's T mobile, with the splash screen and my tmobile app and EVEN a Device Unlock app.
So I took out my sim and tried flash with no sim inside, it's still T mobile. I don't have the original sprint sim card anymore. And the present of the Device Unlock app is driving me crazy, and I also scared that the ota will brick my phone.
Please,anyone know how to fix it?
Are you flashing using the app data file?
Do you have any other non-Tmobile SIM card to check if your phone locked itself to Tmobile?
You might have the device unlock app installed on your phone, but this doesn't mean the phone is locked to Tmob.
Insert a non-accepted SIM card as here: https://www.unlockunit.com/blog/network-locked-t-mobile-usa/
And let me know the message your phone displays.
Also, check your IMEI if it's recognized by T-mobile servers with their own service here: https://www.t-mobile.com/verifyIMEI.aspx
