I have a Galaxy S3, after a phone update my APN settings reverted back to the original ATT settings and my ST APN disappeared. This setting worked for me. Thank You!

There are tons of unlock videos on the net anyhow. For some reason my phone locked itself (bought it unlocked, formally an ATT phone) after I did a factory reset. It took a bit but I found the unlock code fairly easily. There are also sites that you can pay like 5 bux and they will send you your unlock code.

Re: Straight talk apn settings for at&t samsung galaxy s3

Everything is working for me, except that I'm not seeing LTE. Supposedly, ST offers this service according to this link.

Is there an APN setting that unlocks the LTE feature? Right now, I'm getting 2.14DN / .67UP with data. Pretty pathetic.

I have at&t sim, everything works but I can't send MMS. I can receive them. ST doesn't have an answer for me. They blame it on the phone. Anyone figure this out?

Re: Straight talk apn settings for at&t samsung galaxy s3

I have an at&t samsung galaxy note 2, and as of a couple hours ago can no longer send a message, I can receive them as well as mms, just can not send a message. Straight talk said to do a master reset on my phone, he was an *****, then he tells me to just keep the battery out for about an hour because everything is right on their end, well obviously it isn't!! Beyond mad at straight talk right now!!!

Hmmmm. Then it may not be a problem on our fone. Sounds like ST needs to fix it. Thank you Jennifer. Let me know when/how u fix it.

Re: Straight talk apn settings for at&t samsung galaxy s3

I sure will!! It was working 2 hours ago, and now nothing, ST said it was probably a tower issue, I actually think its something on their end. Sometimes I have real good luck with Customer Service, other times, not so much. Today was one of those days. If yours starts working too, please let me know. I've even tried changing APN settings with no luck!

Everything is working in KCMO area just fine. The only time I have had trouble with ST is when the ATT towers are down. I had them since December last year and only one day of trouble.

Roger, have you tried calling Straight Talk? I have reset my apn setting 100 different ways trying to get it to work and still nothing. Maybe if enough people complain to ST they will start looking into it.

Not yet. I too have tried every combination of APN's from here, from their site, and several others. Nothing will make it work. I will have to make the call.:(

Here you go:

Name=Straight Talk
APN=tfdata
Port=80
MMSC=http://mms-tf.net
MMS proxy=mms3.tracfone.com
MMS port=80

Reboot

Go into messaging, General settings, Message center and enter the following:
+13123149810

To test send a text message, and send a mms (picture) to your cel fone.
My phone is now working 100%.
Also, my phone now says 4G lte with 2 bars

Ok David, you are welcome, happy to help someone else. Thats what makes the forum great!
FYI to anyone, your 4G lte will not be on if you are connected to a WiFi. Ask me how I know.

Can't get this to work for me with incoming MMS. I can send MMS fine though.

Weird.

I also don't know what to put for all the other settings like apn type, authentication settings. Right now I just left them blank.

Also what do you mean go into messaging general settings message center? is that inside the messaging app? If so I can't find these settings anywhere.

My data works also on these settings.

thanks for any help.

Re: Straight talk apn settings for at&t samsung galaxy s3

question, i ported my number from one of my old ST and i have a MCC of 310 and a MNC of 120 instead of 410, would that make any difference to my connection?
