See this is why I'm confused. I've seen several things about unlocking the phone for StraightTalk. Do I have to do that? I have a T-Mobile Samsung Galaxy S 4G that I used with my T-Mobile contract and when I cancelled my service and bought StraightTalk they just sent me a SIM card in the mail, I popped it in and changed the access point and bingo. I thought that all phones with SIM cards worked that way, but now I'm seeing all this stuff about unlocking the phone for StraightTalk.

When you get a Straight Talk SIM, or a Straight Talk phone, you choose based on the carrier you want. This will likely depend on which carrier has the best service where you live and/or work. When you get a Straight Talk SIM, you get either a SIM that uses AT&T service or one that uses T-Mobile. Straight Talk AT&T SIMs actually aren't available anymore unless you get them from a 3rd party. If you get a Straight Talk SIM using AT&T, it will not work in the Lumia 521 (unless it's unlocked). A Straight Talk SIM using T-Mobile will work in the 521 without unlocking. The phone is locked to T-Mobile, but your SIM uses T-Mobile, so you're good to go!Current lineup: Nexus 6 (primary device) and Lumia 920. There are several others as well, but they come and go!

Thank you!! It all makes so much sense now. I have another related question. My Samsung Galaxy S 4G has both the T-Mobile and StraightTalk access points listed, and it won't let me delete the T-Mobile one. Also, after a few minutes it resets to the T-Mobile access point which doesn't work. So every time I need to use data I have to go into the networks menu and change the access point back to StraightTalk. Am I going to have the same problem on the 521?

You DO NOT need to unlock a T-Mobile phone to use with a Straight Talk T-Mobile SIM. Go to their site. Tell it you have a T-Mobile phone and you will get the right SIM. Also, I have never known Straight Talk to use any CDMA network. Lastly, they no long sell AT&T sim cards though you cna buy them on ebay.
Straight Talk has the correct settings you will need with your 521. You will not have to switch info past the first time.
While I don't have Straight Talk for T-Mobile (I have it for At&T), it is the exact same idea.

So what did you end up having to do? Buy a at&t sim card? I currently have the samsung proclaim it was free w a straight talk service purchase. I don't think the phone has a sim card in it. I am thinking about buying Great Condition Nokia Lumia 521 for T Mobile Monthly 4G 610214632074 | eBay this. So I would need to buy an at&t sim card from ebay to use with straight talk because t mobile service is garbage where I live?

Yeah 521 is a T-Mobile phone so you would need to use a T-Mobile SIM with it, unless you could get them to unlock it which I hear is pretty much impossible. If you get the T-Mobile SIM from ST, your service would go through T-Mobile so if service sucks take that into consideration. I think the Lumia 520 is pretty much the same phone but for ATT so you might want to look into that. I love the 521, its a great phone, has Windows 8, and has a wonderful display. There's less memory than other phones, but they have to cut the cost somewhere. For the price, it definitely can't be beat. Although don't get any liquid on it at all!!! This is the least water resistant phone I've had, but that's another story...

Getting tmobile to unlock your sim for use with another carrier depends on your plan with them, I recently bought my Lumia 521 for use on tmobiles prepaid plans if that is the case you have paid for the device in full and they will not give you a problem, otherwise if you have some sort of contract there are certain conditions which need to be met before they will give you your devices sim unlock code. As for carrier compatibility I switched to straight talk and have had no problem bought the new sim card put it in the phone and entered the 20 digit unlock code and in was good to go, hope this helps.
