Data won't work, what are the correct APN settings and how can I set them?

[abrennan94]

I have recently bought a supposedly unlocked galaxy s4 active at&t and switched it to straight talk. The phone works but I cant get the data to work. I followed the directions they gave me to edit the apn settings, but it wont allow me to edit anything. Does anyone know how to change them or what I should do.

I had the same issues. But my phone is not unlocked.

Name- straight talk
APN- tfdata
Proxy, port, user name, psw, server_ NOT SET
MMSC- http://mms-tf.net
MMS port- 80
MCC- 310
MNC- 410

These are the ones the tech gave me. Only issue my text will not work at all. They told me it is not supported by straight talk network

Hi I have a galaxy s4 active I just activated it to straight talk byop (at&t) everything works except I can't browse the internet or send/receive mms. I've been reading different things online tried many apns none worked FINALLY one worked my phone went to 4g I sent an mms and received one back and checked fb LOL this is what I used...
APN: tfdata
MMSC: http://mms-tf.net
MMS PROXY: mms.tracfone.com
MMS PORT: 80
APN TYPE: default,supl,mms
Then BAM as soon as I turned my Wi-Fi on 4g disappeared now there is an E? Not sure why I tried turning my Wi-Fi off and nothing can't do what I could just a minute ago PLEASE HELP I'm not sure if it's just because I have bad signal where I live or because the apn settings..
