I am running the samsung note on straight talk, I have the international version... you can find the apn settings here, but when you purchase the sim card thru straight talk, it does not give you an UNLOCK code, it just sends the sim card with the APN settings that you have to change. This is a great plan and works for the note, but there is a drawback I have had with my note... sometimes when im searching online, or running an app that uses the internet, the internet cuts out completely, and I have to go to settings and disable data network and re enable the data network to force it to come back on... then I have a network again, sometimes it just goes right back out and I have to do it again... It is a pain. I bought my note on craigslist for 500 about 3 months ago. I used at first the sim that came with the nokia e71, it works, the "bring your own sim" doesnt help with the internet problem, they say its for "at&t" network that the straight talk sim wont work, the sim is EXACTLY THE SAME.. and still having the network issue. It did not do this at first, but once I got into using the phone and got that phone call where they told me I was going over my 2GB limit or w/e and they would ban my account if I did not slow down on surfing the web, thats when it started doing this and when you call u get a foreigner that doesnt understand anything, and cannot help you, so good luck! If you have any more questions about it then PM me.
Also forgot to mention, you DO NOT GET 3G. You only get the H+ crap, idk if thats any good or not... my phones fast for straight talk, but if you want to watch you tube and stuff theres a lot of loading involved..... also, when you go online your network will keep switchin from H to H+ to 3G and back to H+ and normally stay there, never have 3G for more than 1 second.
