Hey guys
So I just got my LG Quantum off ebay. I put my Rogers sim card in and I boot, it tells me it cant recognize that there is a sim card or it is invalid. Im not sure what to do. I am switching from a Samsung Focus so there shouldnt be a problem. Yes the phone is unlocked, well the seller said it was unlocked but I wont know until it recognizes a sim card. Any help or ideas out there?
Anyone? bump

Sorry, I only check in every couple of days.
Sounds like your phone needs to be SIM unlocked. (I.e. the previous owner simply sold you a phone which is 'locked' to another vendor's network like AT&T for instance).
What you need to do is go to eBay or google for "LG Quantum Unlock Code". You'll need the IMEI (inside the battery compartment) and it shouldn't cost more than about $20.
Well the thing is the seller sold it unlocked. But Im skeptical, so I bought a code and such from cell unlocker, but the issue is that it doesn't recognize that there is a sim card inside of it. I have tried 2 bell sim cards, and 2 rogers sim cards. This is the problem because with the quantum there is no way to unlock it that I know of that doesnt require a sim card. It hasnt recognized any of the sim cards, it boots up and sais that there is no sim in the phone.

That's weird, it should at least prompt for PIN, PUK or unlock code. I would try:
1. Reflashing and then try if it asks for unlock code

2. Rebel Sim II 30$ (SIM card chipping)
3. Octopus India, 83$ (Unlock/repair tool)
My Quantum in is "PUK-code-loop" and unlocking code, reflashing or correct PUK wont help.. Rebel SIM II is on way..
I finally managed to unlock using Rebel SIM II:

I just got a Sprint galaxy note 3 and im trying to make it cricket with the new gsm network. I ordered a sim card and I attempted to do the sim unlock but it is not working. I rooted it and verified that it is rooted with an app to check it. I also installed super su like the directions said and also installed region lock away. I still cant get the phone to accept the sim. It says "invalid card". I checked the Stats on it and it show network unknow. It doesn't even show the phone number program onto the sim. When I take it out it switches back to sprint.
Sprint sim slot is only for lte on sprint in the us...
You need a gsm model such as att or unlocked t-mobile note 3!
Hello, recently I set up my L720T on Boost, however it rejects the SIM card during the activation process and then locks it out, then leaves an error saying no SIM card. Does anyone no of a trick or possible the OTA app from a Boost ROM for L720T that I could install and have the activation process go through?
Thank you for any help I'd appreciate it.
EDIT: This isn't one of those donor phone flash things, I called Boost to resku the S4 IMEI and the SIM was originally different. When I popped in an approved SIM they said it should automatically authenticate but that's not what's happening.
The ICCID of the new SIM wasn't updated in their system at the time of RESKU. It will not automatically update. This requires their intervention.
I bought a new S5 that was Vodafone, of course I put my three sim in and it asked for a network code to unlock it, not wanting to pay for one, I rooted and installed a H3G 6.0.1 Stock rom, put my sim card in and now its saying no sim detected, and shows no signal at all. I remove the sim, it says please insert sim, emergency calls only. :/ Any suggestions?
Sorry if this is posted somewhere, but I could not locate it. I bought a consumer cellular SM-J737U, which runs on att and tmobile towers. When I inserted the t-mobile sim, it prompted me to reboot for network change. I did, and I have full LTE for a few seconds then I got an error message saying this is an invalid sim, contact consumer cellular for help. So I know the sim works because I had full connectivity on there.
What do I need to flash to goto stock J7 stuff so I can use my tmobile sim?
I tried another sim and the same thing happened.
