[Q] T-Mobile Samsung Galaxy S 4G on AT&T Network..

I gave my old Samsung Galaxy S 4G phone that I had on T-Mobile to my girlfriend and unlocked it through t-mobile to be able to use it on her AT&T network. She placed her AT&T sim card in the phone and I unlocked it. The phone works fine but it will not go past "Edge" speed, is this due to the different network frequencies or is there anything else there can be done so she can get 3g at least? Would I have to Root the phone to be able to do so or is there any other easier ways to go about it? Thanks in advance for your help.

I switched to AT&T to get the HTC One X, but I hated that phone (but it had a nice camera), so I got the AT&T Galaxy Note.
I unlocked my SGS4G so I could use it on AT&T to test radio changes, but also I noticed that I only got edge. If I go outside on a really sunny day sometimes I see it get hspa, but I don't think t-mobile phones can get 4G on AT&T's network.
I would expect at most getting edge. The ONE time I did see the phone go to hspa, I still didn't see xfer rates increase. It was slow as hell.
I think the answer is finding the right modem.bin. Our radio device is a little different then the other galaxy s phones, and most of the ones that use this same modem are on t-mobile. I'm hoping to find another phone that uses the same modem on at&t.

Actually, I was wrong. I was hitting the same stupid build prop thing where you're only on hspa if you're using data. If not it bumps you down to 3g.
AT&T works fine on this device.

Yeah, I just recently moved to AT&T bringing this phone. It shows a 3g status but seems to be as fast as it was on T-Mo but depending on the location. My wife has the same device on T-Mo and we drove from Chicago to Florida finding that usually one of us had a signal.
The visual voicemail isn't available from AT&T on this phone but the basic v/m works

I need help on unlocking my SGS4G for AT&T. Every time I try the app method, it either returns the code as "null" or has some busybox error. And the hexcode method doesn't work because mobile terminal can't find the file on my phone. I am running Beanstalk 4.4 ROM, and it is rooted. How can I unlock it?

Try going back to BML and unlocking there as the methods that you'll find on this forum are more reliable that way.
This is one of the free methods I have:

It is on BML, I'll try those methods but if they don't work I'll probably have to flash back to stock, root, and then unlock it.

I've read countless posts on here saying that was just a kernel... Thanks for the correction

@champ1919 is correct, BML refers to stock touchwiz roms. I recommended that because although I don't own this phone anymore, I wrote the unlock script a while back and I know it works fine on stock roms if you install busybox from google play, after rooting the phone.
Once your phone is unlocked, any newer roms you install will keep the unlock and if you decide to go back to stock after THAT, your phone will still remain unlocked.

This seems like the most sure fire way of going about this, I haven't had time to do it yet but I think I'll go with stock then unlock.

[Q] [K2_PLC, Cricket]Cricket 4.2 MSL thingy is weird?

So I was messing around in the ##3282# settings, and I clicked "Edit Mode". I thought, "Well, let's guess." I inputted six zero's, and to my surprise, it was the correct MSL code. I don't know how this is but now I can edit the stuffs. Also, this phone has Band 25 LTE 0_0 I didn't know that. Can any of you Cricket users verify that this is only me?

MSL Reader (see the play store) gives it to you if you are properly rooted. Its how I retrieved mine. But I know six zeros won't work on K2_CL lol.

Didn't know that I could use that 0_0
So, there's a bunch of stuff I can do now with the PRLs hehehe
Maybe I can flash to T-Mobile, they have a $30 5GB unlimited plan. (Prepaid, and SIM Card)

Educate your self!

I dont know all the specs behind it cause there was tons and tons of info and I kinda spiderwebbed out of control reading it. But the jist I got is this PRL's APN's and all that get more credit then what they are deserved. Yes to have a proper one is beneficial but its more about the codec's the radio signal of the phone and towers your connecting to and the system files in your phone itself that will allow you to do what you need to. I am still piecing things together but I am working on a finalized cricket fix to allow the use of LTE, the use of gsm or cdma and the use of European roms. It has become quit the undertaking but before you jump in and start changing files that were initially fine I would properly educate your self on the pros and cons changing the prl.
As of yet I am pretty sure Tmobile wont flash the phone nor will our phone work on the Tmobile network

Shhh....I realized the One SV is CDMA on Cricket a long time ago. Mm'kay. I also left this device...so there's that too.

Lol I was just going through threads and it's also helpful info for others as well

I have an HTC one SV from Cricket, I like the phone but am not "In love" with it. My problem is this- I just bought the phone then changed providers due to poor service at my address. Since my phone has a SIM card I thought I could switch to AT&T but the phone never accepted the new SIM. AT&T couldn't find out why, Cricket told me their was no unlock code, HTC said it wouldn't work until they ran the date of manufacture and MEID# then all changed.HTC told me to get the msl and I can change the network settings so I I can use GSM instead of CDMA. Any warnings, advice or instructions?? Out of severe stubborn motives, if at all possible I want this HTC on GSM just to prove that I can lol.

[Q] How to get Nexus 5 to work on Sprint

I recently bought the nexus off someone and found out it was the one that came from tmobile but was factory sealed. I put in my sprint sim from my htc one but it wouldnt activate to the network. after the setup process it shows that its on sprint but cant make or receive calls or texts( no data). I know the nexus can work for all sprint its just getting them to enter in the IMEI manually which they say they cant do. Id rather not go through the process of reselling and finding on that someone got from sprint so has anyone gone through this issue that got it working?

you have to call them to add your imei into their system. nexus 5 that sprint sells already is in their system, but yours came from tmo. so it manually has to be put into their system. problem is many sprint reps dont know that and will tell you its not sprint compatible. but it is, they just dont know.

Ill have to go to an actual sprint store ( and not the retail owned on near me) to see if they have experience with it. Calling customer service yielded me no help. Would rooting be an easier approach?

If you live near a store - go. But now you know what you're asking g for, calling should be easier.
Not sure how you think root will help? You can't force your details into the sprint system with root.

you usually have to get a tier 2 tech support person to get the IMEI added into their system.
root has nothing to do with adding stuff into their system.

To be able to flash sprint radios. Though if activation can only come through the store then ill go with that

- You don't need root to flash radios
- Radios won't help you connect to sprint
- Dont think there's such a thing as a sprint radio on the n5
- All radios work on sprint.

While there technically is no such thing as a sprint specific Nexus 5, from a practical standpoint there is in that Sprint did not load any of the IMEI numbers into their system from the devices that were sold directly from TMobile. Without the IMEI number in Sprint's system, their frontline agents have no way to activate the phone. As was mentioned in a previous message you have to get elevated high enough within Sprint to get the IMEI number added to the system. I have not personally tried that but have heard that the results are hit and miss.

Nexus 5 on Verizon

Just wondering does anyone think/know if the nexus 5 will be able to utilize Verizon network since they will be offering the nexus 6 and the nexus 5 is compatible with their network?
It sure would be nice to have my nexus 5 moved to Verizon. And this is not an actual question just thinking out loud rather. In any case if this needs to be moved then by all means mod please move it.
Also Verizon now has the bring your own device program as long as its compatible with their network.

No, no it wont

A new phone comes out that works on said network. This obviously means the old phone that doesn't will suddenly work too right? Use your brain.

Not to be a downer but this has been asked multiple upon multiple times on the Nexus 5 forum, a simple google search would have given you the answer you needed.

Technically it is compatible since it works on Sprint and someone stuck a Verizon SIM in and got LTE. You probably could do Page Plus or similar since they can add ESNs.

no no no no. Its compatible with 1 freq band and from what ive read its only LTE and VOlte that works, which means 99% of the places you go it wont work

There is only data. No voice.

Well the phone is compatible based off the bands the radio utilizes. My question is since Verizon is opening up to what phones can be used on their network is there anyone who works for Verizon know of they have plans of allowing the nexus 5.
Their prepaid Boyd allows you to bring a Verizon branded phone and or compatible phone, not sure about the last part because the wording is confusing.
Also Verizon allowing the nexus 6 to work on their network could be a stepping stone as they have the same bands. Google has said they will not be discontinuing the nexus 5 which makes the phone still relevant.
Again I am just seeking anyone with knowledge as to if Verizon with the changes they have been making will allow the ESN to be added to their data base and the phone used on their network.

Right now it won't work. What they do in the future, only Verizon can answer. ?

OK so I stand corrected about the LTE bands. But if you can get the ESN added or use a prepaid or MVNO you should be golden. There is a thread on flashing CDMA. But my point is it isn't 100% negatively impossible.
If you have decent AT&T coverage and don't want to pay for it though, Cricket is a good option as well.

It is currently at this time, 100% impossible to get a nexus 5 useable on Verizon.

I guess people don't read the older Verizon and the n5 threads, and/or they just don't believe them, and do everything all over again(like its a new idea). then they realize the truth later on. anyways, you can use your n5 data only on Verizon, and use the hangouts dialer with your google number to make calls over data. but that's it.

I'm honestly surprised these threads don't get locked since there's so many of them. One of the others should be pinned so that people can stop asking this.

Might as well ask: S7 from Sprint to ATT

I'm kind of newb at this S7 stuff, I'm more of an HTC guy. I bought an unlocked G930P (sprint) and want to go w/ T-Mobile. I know the SIM card "just works" and I can change the APN & all, but there are some things I'm unclear about, which I am mostly guessing at from my HTC knowledge.
1. Suppose I don't update any ROMs at all and just use the phone. Will it be using all the bands that T-Mobile uses, or just some of them?
2. Does the over the air bands it uses depend on the baseband that is on the device? Will I be missing out on some bands because I have the sprint firmware? Can I update the baseband?
3. I heard T-Mobile uses an updated boot kernel (3.0?) and ATT & others use an older boot kernel. Will this affect my use on T-Mobile if I'm using a 2.0 boot kernel?
4. I don't like all of Sprint's bloatware. I'd rather use a stripped down, cleaner ROM. Can I clean up Sprint's ROM and get that stuff out of there?
5. I'm assuming T-Mobile has some nice for-TMobile-only apps. (Like Wifi calling?) Can I switch my OS ROM over to TMobile from sprints? I'm guessing NOT.
I'm considering selling the G7 I just got and going from a G930F (now that I'm a bit wiser). Any common sense why not to do that? I already HAVE an ATT G7 (not the sprint one I just bought), but it has a "bad signal". It gets only about 1 bar indoors, on a good day. I took it to a repair facility and they said, "nothing wrong with the antenna, it's your mainboard, don't bother just buy a new phone". Anybody have any advice on that line?
thanks

Hi mate
You may have better luck asking that over the right forum, check here

First place *I'd* look to move my sprint phone to T-Mobile would be the T-Mobile forum. Then I thought, "why not post in the general section, see what sticks"?
for what it's worth, I *only* used Odin, got the G930U firmware, and odin moved my phone right to the U firmware, without any other issues. It was so weird to see that happen without fuss. After the phone rebooted, I downloaded the latest OTA and it worked. It's still on 6.0, but it seems like a legit process.
