3G/4G Menu

Where is the hidden menu for the 4g preferred setting? Isn't there a hidden setting menu. My phone tried to stay on edge. My little brother has a blaze and is right next to me and his is on 4g and mine is on edge....
I still have IMEI so that isnt the issue. :good:

go to the play market and download phone info

Should it be set to gsm/cdma auto(Prl)?
It was on gsm auto (Prl).
It seems since I flashed a Rom and then did my Nan restore to stock rooted it preferred edge over 4g.

no if you want it to prefer 4g ovr edge then you have to have it set to wcdma preferred. that's tmobile's 4g! and then when it isn't available it will simply go to edge. that's definitely your best bet.

I did that now. It still was sticking on edge. I then switched it to wcdma only and it switched right to 4g. Thing is on edge it had full bars. 4g only two. I wonder if that's why it stayed on edge. Anyone know?

So I'm visiting family in Toms River NJ and I have full bars of Edge service, but no 4G service. Should I try switching network settings or what ??

try wcdma preferred. It helps stay on 4g. There may not be 4g where you are. Might want to check on that.

So I did this same thing and it's telling me I'm on 3G.
When I was on completely stock ROM out of the box, I was on "4G" all the time.
Now, every ROM I've flashed to test out which one I like, it displays 3G BUT whenever I click on a link it switches to H+. Then when that link is done loading it switches back to displaying 3G. Am I correct in assuming that it is supposed to do this?
Edit - After reading the NEXT post while I was doing my search, it seems that I was correct. :]

correct you are. while It's accessing data it goes to H+

I have my set to wcdma preferred. Keep in mind this setting might use more battery because it's constantly looking for four g signal rather than two g or three g

If I'm not mistaken, on stock it will always show 4G, even on 3G.
A lot of custom roms change this so it tells the truth. That's why you see 3G or H/H+.

4G and 3G are not actually different for Tmobile.
Wikipedia article on Evolved HSPA
So then, the question is how to turn off DC hspa. Which is probably not accessible through the maintenance menus.
But for many real world value metrics I don't know what you would gain.

Get the app called phone info

I think there's an app for that. I forgot what its called but I think the toggles are Edge or HSPA+ umts only

I'm wondering if the OP came from Sprint? Sprint's 4G was a separate (battery sucking) radio that you could turn on and off and needed to in order to protect the battery usage.

4g on TMo isn't like LTE, it's not a separate modem to turn off like AT&T, VZW, or sprint. It's really a hopped up version of 3G. Your choices are 3G/4G or Edge.

On T-Mobile, there is no real differentiation between 3G and 4G. Both operate on the same spectrum. The only difference is the speeds. However, that is controlled, not by your phone, but by the tower you're connected to. It's easier to look at it as the same exact technology. For the purpose of this conversation, there is no more T-Mobile 3G. It's all 4G, or HSPA+, service now. The 3G brand has been retired in favor of the 4G moniker.
To put it all simply, 3G is the same as 4G on T-Mobile. To turn off 4G, you would drop down to 2G, or EDGE/GPRS, service.

And if you still want to do it.....go to settings - more settings - mobile networks - network mode and you can select "GSM only".
Strangely enough....there are a couple areas around where i live that my phone will show a 4G connection and absolutely refuses to open anything. I've found that if i switch to the "GSM only" option in those areas that at least i can get it working... slowly, but better than nothing.
Had the same issue with my previous phone. (G2) weird phantom 4G zone. :-/

Mobile data not working

has anyone had the issue where their phone won't connect back to 3g data?
when I reboot my phone 3g will work until wifi kicks in. after I turn wifi off 3g comes back, I can call and text but will not download any data.
I have tried Odin back to stock. wiped everything including recovery. I have tried flashing every combination of modems and kernels. all same.
however one thing I will note. I have not been able to get a successful modem flashed in Odin. it keeps failing. so I flash in twrp.
I also wiped the activation data via ##732# or something like that. had sprint reactivate my phone too..
perhaps someone could shed some light on this?

I just got my Note 2 like 5 days ago and mine does the same thing. Its very annoying and its gonna be exchanged today for that and other reasons.
Sent from my SCH-I535 using xda premium

hmm. I wonder if it's network related..
is your phone stock?
-Wizzle

Okay here is the skinny. It is network related. My wife's stock s3 does the same thing. If you are in an area without lte and your phone under mobile settings is selected to lte/evdo/cdma it will connect to ephrd13. Which is enhanced 3g. When you come off wifi or a phone call sometime it will not reconnect. You can toggle data a few times and it will reconnect.
To solve this issue, under mobile settings I select evdo only setting being that I do not have lte in my area. There is no change in speed between the 2 3g networks.
This info is from self diagnosing the rooted note 2, a stock photon, and a stock s3.
I have had sprint reset the phones as well as the ##data# trick.

yeah I did the ## thing. however it came back. so someone from sprint called me to see if Iwas happy with the support and I told them I was still having data issues. He told me that he would put my ticket in priority and after an hour everything has been working better so far...
but we'll see

Yes changing to evdo so far has helped alot. I really appreciate the info. Thank you.

When I say evdo only I meant cdma only. Ehrpd13 is the handshaking 3g for lte. Some areas have lte in the towers but no ehrpd13 so the lte is not turned on yet. Basically ehrpd13 and lte are like cookies and cream lol.

The problem is my area does have it but at my house its very weak. My ohone wikl display 4g but it wont download anything untio it switches to 3g.
Sent from my SPH-L900 using xda premium

When the 4g network matures as it will the 4g will get better as the 3g.
You can always go to I think s4gru.com. That site shows when and where lte will become available. Plus they will be able to help you better there than xda.
As for sprint customer service, they are laughable at best. 4 people I spoke with didn't know what ehrpd13 was lol.

[Q] HSPA Problem

I have S2 and ever since I started using roms i don't get 4g anymore. It shows HSPA 10.

That is the 4g network for tmobile. You should see 4g or h+ in status bar and hspa 10 or 15 in settings

Yup. H+ on aosp roms is 4g. Its just a cosmetic difference.

So download speed shouldn't be any different than Stock Rom correct? oh yah btw does T-Mobile US or T-Mobile US LTE apn actually make a difference sorry new to this rom stuff and how come i'm only using 3g for calling? Cause Stock rom used 4g im pretty sure and it was much clearer

CarbonROM AT&T GS3 rotating between 3g and HSPA+

Recently flashed CarbonROM and now my phone rotates between 3G and HSPA+ when both are listed as full signal. Is this a ROM issue, Phone issue, or AT&T?

Its not an issue. AOSP based ROMs show 3g when data isn't active and H+ when it is. stock ROMs incorrectly label H+ as 4g.
Sent from my SGH-I747 using xda app-developers app

So it isn't a matter of me having signal or not? It's just going to say H+ when actually using data and 3g when im not?

H+ is not LTE that is correct. On AOSP ROMs LTE is displayed as 4g. If you are seeing H+ then you are either not in an LTE reception area or your APN is wrong.
