T-Mobile Galaxy S 4 and ATT Straight Talk SIM - Galaxy S 4 Q&A, Help & Troubleshooting

Hey All. I currently have a Galaxy Nexus with a ATT Straight Talk SIM. I am buying a T-Moble Galaxy S4 today for $320. I want to use it as my main phone, but I know I will have to unlock it and cut the SIM card. After I unlock it will I be able to get 4G speeds? Or will the band difference screw me? What if I was to get the new LTE straight Talk SIM Card?

[Q] How do I get my AT&T S4 to work on tmobile 4g network

Hi,
I just received a S4 for AT&T. I have service with T-mobile. With my previous phone (At&T galaxy note 2) the T-mobile service was absolutely horrible until I found a tutorial to run T-Mobile 3G/4G AWS bands on the AT&T Galaxy Note 2 SGH-i317. So in order to receive full tmobile 4g on my AT&T S4 will I have to go thru the same process?? or will just unlocking the and putting my the phone be sufficient. Please let me know:good:
thanks in advance
I unlocked mine this morning by putting my coworkers T-Mobile SIM card from his S3 in my AT&T S4. After a swift boot up it showed T-Mobile 4G in the status bar so just putting the card in will be enough to get T-Mobile's 4G variant.

Note 3 SM-N9005 with Verizon

Can an international Galaxy Note 3 (model SM-N9005) work with Verizon?
From what heard.. I would have to get a replacement SIM card from VZW and use it on the SM-N9005's first boot
Cuz,
You will always have to get the sim from the providing service carrier unless you are willing to pay long distance charges!
You can get a Verizon sim for an ATT network, you may occasionally use a competitors tower but the service COMES FROM the sim!

sim activation

I purchased a tmo note 4 and unlocked it run on att. I took the sim card out of my note 3 and put it and it provisioned by itself. I currently have lte even though att sees the phone as a blackberry 7100g. Since I am getting lte I was going to let my nephew use the note 3. Unfortunately the phone he has now is not an lte phone and uses a standard sim card so I can't stick it in the note 3. Can I buy just a micro sim card from att and ask them to activate with his phone number without having to bring in the note 3? Then I could put it in the note 3 and he would be good to go. I don't want them turning off the lte on my note 4 and I would rather not give them the imei from the tmo note 4. I wasn't sure if I should post this in a specific carrier forum.

Possible to SIM UNLOCK AT&T Tab 4 10.1 to use on SPRINT?

I have an AT&T Tab 4 10.1 rooted and would like to use a SPRINT LTE SIM card in it. Is this possible? When I insert the SPRINT SIM it asks for a SIM unlock code. I do not have an AT&T account and never did, just Sprint. Any advice is appreciated, thanks!

Straight Talk Samsung Galaxy S8 sim unlocked by default?

Just bought my Straight Talk Samsung Galaxy S8 from Walmart, so I took the Tracfone sim card out and put a AT&T sim card into it, it works!
My question: Is the Straight Talk Samsung Galaxy S8 sim unlocked by default?
Thanks in advance
I tested mine with all four major carriers, ATT, Verizon, T-Mobile and started a Sprint free year on the device, so I guess the Walmart Straight Talk S8 is fully unlocked
