4g on a 3g Samsung Vibrant T Mobile - Vibrant Q&A, Help & Troubleshooting

Hey guys, noob here, and I just recently flashed a ROM I found on Xda that supposed to be just like the droid razr. I am loving the ROM but something is confusing me. Sometimes my phone shows 4g LTE in the status bar when my phone should only be getting 3g from T Mobile. I checked on the guys page and I can't find anything on the subject. Is it possible that my phone is getting 4G coverage?

I highly doubt it since the vibrant only supports 3g now as for the t959v thats the 4g varient of our vibrant with a different modem if memory serves me right.
Though I have noticed my 3g speeds down right blow past my sidekick4g's speeds but ofcourse that might just be due to it being a sidekick4g >.>

No, i know what ROM you are talking about. It is a port from the Razr and the Razr has 4G LTE. When it says 4G LTE on the Vibrant it means you have 3G.

Thanks guys I appreciate the responses that's what I was thinking but just wanted to make sure!

You're misinformed, unfortunately. The Galaxy S3 does not have WiMax, only LTE.
setting<more settings<mobile networks<network mode< and LTE/CDMA.
it will require a restart of the phone. hope this helped.
If you are in an lte zone do what post 3 says and you should be up and running, but if not im sorry to tell you but post 2 is correct there is no wimax, only lte but dont worry its much faster and im sure will head to area soon :good:
Thanks i was surely misinformed i thought it had wimax too. Had no clue.

Carrier name issues on T-Mobile

Hey guys,
I'm kind of new to android stuff, so bear with me .
About a week back I bought this Motorola Photon 4g for Sprint off craigslist and used the kddi radii trick to make it work on GSM networks, namely T-Mobile. Right now imeon the hybrid 2.3.5 rom, but even when I was in the stock sprint rom, the carrier name randomly shows up as T-Mobil instead of T-Mobile. Is there any way to fix this other than spoofing the carrier name? Thanks for the help!
From what I know, the name is stored in SIM card, try to replace it with carrier.
Thanks, I'll try that. I'm actually planning on doing that soon anyway . The strange thing is it sometimes shows the full name T-Mobile, I'm still trying to figure that out haha

Where is the trick?

My phone does this too, I'm not sure why. To me it seems like it says 'T-Mobil' when signal is pretty weak, but i have overall weak signal in my apartment so it could just be me making a bad guess.
same thing
i also have the same thing, but i haven't noticed it till you have mention it.
i guess it belongs to 2G/3G. coz when you are having connected to 2G it tells you T-mobil
while when you are connected to 3G it tells you T-mobile.
pleas tell me if i'm right
Can you not get tmobiles 4g or is it because bootloader is unlocked?

Tmobiles 4g is HSPA+ which is technically 3g
Jellybean Poppin MoPho
You guys must be in the refarm area cause the 3g frequencies are the same as the iPhone's. I'm still waiting on that . Btw I got a new SIM and it hasn't said T-mobil yet so maybe it's just a certain kind of sim that does it?

Possible network issues

I live in a 3g only area, and today my phone has started showing 4g sporadically.
When the phone shows 4g my data stops working and then all data cuts out and 3g comes back.
I'm running viper Rom with snuzzo kernel. Could this be a software issue? The Verizon website does not have my city listed for current or upcoming 4g availability.

if you know you are in a city with no 4g and dont plan on getting it soon, why not change it to CDMA only? The phone might think its getting a signal from a 4g tower and its causing it to switch like that

This has never happened before today, so I was hoping it was me getting 4g in my area.....
I tried the cdma only setting, and my data as a whole is spotty now. My wife's thunderbolt is doing the same thing now.
Is this what its like when they flip the 4g switch? Does anybody else remember when 4g came on in there area?

they might be testing the 4g radio in your area and it that might be causing it. give it a couple of days, if it doesnt fix you might want to as a vzw rep. for me it was back when tbolt launched when we got 4g
What ROM are you using? I know that on some ROMS, like cyanogenmod, it's actually best to keep phone on the setting that supports multiple data modes.
I live in a town of 15k and we just got 4G, so u may get it after all...

Mobile Network type is always on Edge?

It's been more than a month and it's stuck on Edge. Even when I go to the areas where I would have a strong signal of 4G, it doesn't change into 4G! This is really bugging me. My phone is S-ON, bootloader unlocked, and running Viper Amaze 1.7.0.1. Oh yeah, and T-Mobile is my carrier!

You need to check your apns and put in the correct t-mobile apn so it will give you the proper hspa+ rather than edge.

Check and make sure your phone isn't set to GSM only under network settings.

Most likely you have gsm only on

Got it! You guys are right, it was on GSM only. I thought my radio got messed up. So is there anyway to get 4GLTE on this phone?
I usually set my phone to GSM Only when I go out, because it saves a lot of battery and still lets me stay connected to the internet.

There is no way to get lte on this phone it doesn't have lte. If it did people would have abysmal battery life because lte consumes too much battery.

HSPA+ is just fine for me. It's beaten my friend's Verizon LTE on many occasions.

Me too. :laugh: Your friend's Verizon LTE was slow likely due to tower congestion. That's when too many people are on the tower and the bandwidth becomes tiny and people get slow data. I hope it doesn't happen to future T-mobile LTE,
My galaxy S6 is stuck on Edge as network type and it refuses to get out of GSM Only even if I try to set preferred network type. I can see the other network types displayed but when I press them it switches back immediately to GSM Only

Am I getting LTE?

Hey guys, I just ported over my number and switched over from Verizon to the One on T-Mobile. As I'm typing this, I'm still on my Verizon Galaxy S4 since I currently only have a temporary T-Mobile number until the switch is complete.
Anyhow, I don't believe I have LTE right now. My coworker has the One and was pulling down almost 30mbps and I can't even hit 2mbps. Play Store downloads are slow, etc.
I live in San Diego which has LTE. I have attached a couple screen shots of what I'm seeing. Am I connected to LTE? Could it be that I won't get it until my switch is complete? Any help would be appreciated, thanks!

I work for T-Mobile and also have the One and no your not on LTE. You are on hspa+. Kind of like 4g lite. When you are in a 4g LTE area, you will a tiny 4g then below it the letters LTE. Hope that helps. Update to the newest software update to get better signal out of the One
