Samsung Galaxy S3 need help w/ APN settings for switching to Straight Talk

I have a G S III that was originally w/ t-mobile but the customer service help said I need to use the settings if it had been with AT&T???? That doesn't make sense to of the APN settings they gave me have worked. My husband has a GS II and in places where he has full coverage I have none w/ my GS III. Also my internet is extremely SLOW and I can not send or recieve pictures either. Can someone PLEASE give me the correct APN settings and any tips to speed up my internet ? THANK YOU SO MUCH IN ADVANCE!:cool:

Did you try these from the website?:[Only registered and activated users can see links. Click Here To Register...]

Thanks for your response. I have tried several. All settings I have taken from the threads on here but there always seems to be some "glitch" that remains. I 'll try that one though. :) Do you know what actually makes the coverage better? I just don't understand why my husband has an S II & I have an sIII both with staright talk byo phone plan but side by side I have no bars & he has full coverage.

Tried that & I didn't have any internet access at all

This is what I put on my sgs3 and my wifes. Everything works and its fast.

@ wickedcontra. THANK YOU, THANK YOU, THANK YOU!!!!!!!!! My gf was really upset, as she should have been that her phone wasn't working. A brand new unlocked GS3 from Best Buy. The settings that straight talk provided worked for about a month, and then just stopped. I've been fighting with this for almost a month now. Again, thanks.

Awesome, im glad it works for you.

So what's hipri for and will it work with/add anything to my ST T-mo settings?

THANK YOU!!!! Got my phone to work with these settings as well...tried another from youtube...it didn't work. SOOOO happy!!! :)

my galaxy s3 from t-mobile doesnt work even after i do all the setting changes. do you one for that??

@Blaize19.....ur settings work gr8t. They are the same that is sent w/instructions on how to setup the SIM card.
I did input those settings but since I didnt read the manual 4 the S3 I assumed it auto saved upon exiting. some of the settings I inputed wasnt there DUH!!!
So all day 2day I couldnt do nething but call and basic txt. No S Voice, no pic txting, no internet, no navigation, ONLY NETWORK errors.
I love GOOGLE......................it found this site.
Love my S3 to and I'm a newbie to it

these settings doesnt work for me on my s3

Hey i have all those settings in my straighttalk samsung galaxy s3. it was an att phone but i cannot get the original att settings to delete so it will work off of the straighttalk settings. any idea how to do that?

you can't delete them as far as I know. Just create a new APN and make sure you save it. Then switch to it.

Im glad it has work for some of you. im still with straight talk using the same settings using sgs3. make sure there are no spaces in the last row.
