[Q] How to unlock phone - Galaxy S 5 Q&A, Help & Troubleshooting

Hi. My s5 is locked to o2 and their signal is way to poor in my area. So I want to put my orange sim card in.
But obviously it doesn't work as my phone is locked. How can I unlock the phone for free. I don't want to waste money if it's possible to do it yourself

Network Unlocking, easy? how?

Hi,
Here in the UK it seems that the O2 network has plenty of Nexus 4's in stock. They provide the phone on a monthly contract on their network or you can buy the phone on O2 pay as you go for £399.
I am currently using a HTC wildfire as my Galaxy Nexus developed a charging problem, therefore I am desperate to get my hands on a Nexus 4 asap. If I were to purchase an O2 pay as you go Nexus 4, how easy would it be to unlock the phone from the O2 network and use my Vodafone sim card with it?
Thanks
From reading other threads it seems the phone comes unlocked?
Has anyone on Vodafone been able to use their SIM with a phone purchased from O2?
It's already unlocked

SIM Unlock Help

just a simple question. how can i tell if my GS4 is SIM Unlocked? i dont have another SIM card from another carrier, and just wondering if there is a way to check it it is unlocked or not. thanks.
Take it to another gsm carrier's store. I took some phones to t-mobile and the guy gave me a blank sim that only made 911 calls. He said old people get those sims for free, so I held onto the sim to test unlocked devices.

[Q] carrier unknown lookup?

long time lurker first time poster....
I have recentlly bought a Samsung galaxy S4 model sgh-I337M off eBay to upgrade from my old beloved S2, It is refurbuished and was supposed to be unlocked.
I have inserted my videotron sim card and I was promted for a code.
I have ask the seller, and he replied that i should be unlocked, but since it is locked I can sent it back and get a refund. This is not the option I want as I got the phone for next to nothing.
Is there a way to know what carrier my phone is locked to? so I can get it unlocked?
I whould also like to had I do not plan on rooting this phone.
p.s Yes I have searched and found nothing.
thanks a bunch.
Sgh-I337M could be rogers

forgot to mention tried Rogers, fido, bell, telus, and videotron sim cards. (what's left koodoo, Virgin mobile, sasktel etc....)
is there a way to know what carier my phone is locked to? without trying every sim card from every compagnie.
ok so now its getting weird, or way more complicated.
found apps that tell me the phone carrier, and lock status
phone info tells me that: mobile operator name: (blank so should be free of a carrier)
Network info II tells me phone status: is sim locked and needs a code
Sim car manager tells me that network type: unknown
network operator name: blank
network operator code: 302610 what the hell is this anyways?
so thats pretty much where i'm at now. any help will be greatly apreciated!
A Google search says that network operator code is for bell canada

If you are an AT&T customer, and there is no remaining balance against the phone, you can call customer service and request an unlock code. If you aren't a customer, you may still be able to get an unlock code, assuming nothing is owed.
Otherwise, you will have to try the paid SIM unlocking services.
I've had good luck with using paid unlock services, available on eBay.
