S g s4 question - Galaxy S 4 Q&A, Help & Troubleshooting

I recently purchased a Samsung galaxy s4 (t mobile). I unlocked it and now I use it with straight talk. My problem is, when I visit home, my cell signal sucks, I was told that what ever phone one uses, straight talk goes off of those particular towers. How can I change my settngs to att so that I can get better coverage?

Is the GSM radio unlocked?

Is the gsm radio in the note 3 for verizon unlocked or locked? I am on verizon right now and can buy a note 3 from my friend for $500 in box, but I want to leave for strait talk when my contract is up in november. Can the phone be unlocked to work on any gsm network I know it has international but verizon has been known to lock out specifically US carriers.
This Verizon note 3 is very well unlocked for gsm..I've used it on straight talk. ..h2o..and even flashed the phone to work on pageplus wireless network. .Only downside is the network icon..you only get H or H+...Btw am on At&t..they have better coverage. ..Now to get a 4G network icon you can go with T'mobile even on straight talk but coverage is just not as good as At&t. Also you can flash your this phone work on straight talk Verizon tower..Google. .

[Q] Switching Carriers & Unlocking Download Booster

i am currently on Sprint and have had it with their service. I live near Chicago, supposedly one of Sprint's maiden Spark cities, and their speeds have either stayed the same or have been worse than in the past. Because I just bought my phone under contract and other reasons, I am looking to jump to T-Mobile.
One thing I am considering is whether or not I should keep my current S5 or trade it into T-Mobile and get a new S5 from them. I know T-Mobile has the Download Booster feature unlocked on their handsets, but I am not sure if this is something deleted from Sprint's handsets before they sold them, or if the device is locked by the SIM or any other reason.
Has anyone else had an experience making this switch? I am curious what others have experienced.
u can not use Sprint S5 on T-Mobile anyway, time for new S5 if u made that switch.

In the past, that is true. The S5 actually uses a SIM card and can be used on a GSM carrier.
lookup Sprint S5 (CDMA) and T-Mobile S5 (GSM) then u will know what is the different.

I am fully aware the difference between Sprint's CDMA network and T-Mobile's GSM network. If you look at Sprint's S5 specs, it still has a GSM antenna. Here's my reference.

T-Mobile S5 on Verizon network... Is it possible?

I've been with T-Mobile for many years and am currently using a rooted S5. Recently moved to a rural area where the only good cell signal is Verizon, so thinking of switching. Is it still true that GSM and CDMA phones are not at all compatible on each other's networks, or is this possible? My S5 is all paid off and working fine, so I'd hate to have to start over with paying for a new device since Verizon has now gone to the same "non-subsidized" equipment model as TMO.
It doesn't look like it's possible. https://community.verizonwireless.com/thread/822033?forceNoRedirect=true

What network can the old Cricket Samsung Galaxy S4 (SCH-R970C) CDMA be used on?

Hi - I wanted to switch to Cricket so I purchased an S4 from Craigslist (beautiful phone & perfect condition) and took it to the Cricket store to activate it. I was told it was one of the old CDMA phones and they can no longer activate them. This wasn't really the story I got when I called Cricket Customer Service and gave them the IMEI, but that's neither here nor there.
QUESTION: What network can the old Cricket Samsung Galaxy S4 (SCH-R970C) CDMA be used on?
The specs on the Samsung site shows it supports the following Frequencies and Data Type LTE: Bands 2/4/25; CDMA 1x/EVDO Rev.A: 800/AWS/1900MHz.
P.S. Searched the forums quite extensively, but to my surprise, I couldn't find much on this. I'm sure there are a lot of these Cricket phones out there though. What has everyone else done with theirs?
https://en.wikipedia.org/wiki/Samsung_Galaxy_S4
Here you can see what different frequencies are used in the different models. That way you can crossreference.
Based upon the frequencies, it appears it could be activated on Sprint or Verizon, assuming either company has a means of allowing out of network phones on their network. High speed data won't be happening with this S4. Sprint Spark doesn't use LTE, and Verizon blocks LTE on phones that aren't Verizon branded.
For anyone else looking in the future: I also found a carrier ting.com that appears to show 4G could be used.
Ting is a Sprint MVNO, which means it uses Sprint Spark for its high-speed data. Earlier this year they started offering GSM coverage, and that coverage apparently is through T-Mobile. HSPA+ should be doable through Ting, just as it should be doable on all MVNOs. LTE is unlikely.

Verizon galaxy s5 16gb on other carriers

Is it possible to put an s5 on another carrier? Such as straight talk.
Apologies if this is the incorrect place to post this I'm pretty inexperienced with forums in general
That is what I'm doing.

I know for a FACT that you can put it on PagePlus. As I had PagePlus as my carrier before I switched back to VZW. When I was researching what other carriers that I'd be able to use, Straight Talk and T-Mobile and, i believe AT&T(?) were the one's I was going to switch to. Don't know for sure AT&T but through my phone conversations with the carrier's and Google'n, i could use Straight Talk and T-Mobile as my mobile carrier. Just Google T-Mobile and Straight Talk. Their website has the information about bringing in your own device....
Another thing to be aware of is the bands that are enabled in your Verizon S5. While you may be able to use a carrier, you might not be able to get LTE data in some areas, for example, because of the bands enabled on the phone.
That may be true. Just check with the carrier as far as what their service areas are. I know that PagePlus uses Verizon towers and you're receiving the Verizon signal. They, PagePlus, had bought a tier of their(Verizon) towers to provide for their Network. Again just do some research and you'll find the best answer for your needs

I had a Motorola X (Developer Edition) that I've used on multiple carriers. It was very easy to switch it from Verizon Wireless to Straight Talk. All you have to do is put the correct SIM Card in from the CDMA section of the kit that you get from Straight Talk out at Walmart. One thing you might want to do though. If you buy the kit from Walmart, make sure to scan your phone at the Straight Talk display to make sure that your phone would be compatible with them. More than likely the Verizon Samsung Galaxy S5 would be compatible with Straight Talk, but doing this will remove any doubt. If you're ordering this online, go onto Straight Talk's web site (support section) and do a live chat with them. You'll need to tell them what kind of phone you want to bring over to Straight Talk and then give them the IMEI of the phone. They can also get you an answer quickly on this.
