sprint ditching 4g and reverting back to evdo ? - Sprint LG Optimus G

Since I first turned on my LGOG in my neighborhood in Miami, I've been on the eHRPD network. This week, however, eHRPD is gone from my whole zip code and evdo_a is back.
While eHRPD gave me crappy signal and horrible data throughput, evdo_a at least gives me 1Mbps. But does that mean sprint is abandoning 4g LTE for my zip code?

maybe working on it or upgrading? doubt theyd go backwards lol

Maybe a dumb question but is your mobile network mode set to lte/cdma?

This doesn't even make any sense...

^ What he said
Wonder if the OP knows that eHRPD and EVDO-A are broadcast from the same tower on the same channel using the same technology and the same backhaul. It is one signal, not two different signals.

I'm seeing this in my area too. Looks like ehrpd was stopped from broadcasting, logcat shows its not even trying to authenticate or connect to ehrpd. but lte is still broadcast. Time to check s4gru.

I still have 4g, but I've noticed a difficulty in transition between 3g and 4g. Also, getting the IP errors like I did with Wimax. This has happened in the last day or 2.

Are u all on ota jelly bean? Jelly bean may be the culprit! I haven been having the same issue in chicago, and my text werent going through.I reverted back to ics now and the problems are gone.

Latest update, prl, and profile update? This is probably dumb question though. I can actually see the tower I'm connecting to. Last I heard, San Antonio is only about 25% complete.
Edit: I also disabled automatic connections under mobile networks. Not sure that has anything to do with it though.

Have you applied the latest OTA update (v L710VPLG8) to your phone? This update contains an important fix to optimize LTE connectivity.

I'm at San Pedro and 410, but the phone automatically connects to my home Wifi. I drive around town all day long and so far, compared to the Evo 3d I used to have, the speeds are ****ing great.

Your LTE experience may well improve after applying the LG8 update. It includes an important fix to the logic governing when the handset will connect and/or disconnect from an LTE tower. You and all the others trying to test LTE service in the newly "launched" LTE markets need to understand this. In several scattered but related threads in this forum, it is apparent that the commenters reporting their LTE experience are mostly ignorant.
Users in places such as San Antonio, Houston, DFW, Atlanta, etc. who are trying LTE with this phone have faced two problems:
The markets were officially "launched" July 15 with only a small fraction of their towers ready for LTE, although work continues on the build-out.
The new LTE handsets, including the GS3, needed OTA fixes to change the signal-strength threshold governing LTE connections. Without the fix, phones can only get or hold an LTE connection that is quite strong.
The second factor just multiplies the damage caused by the first.
I have tested my GS3 in a city that has its LTE network substantially built-out (Waco). Before applying the LG8 update, even where the LTE signal was very strong, the phone did not connect. After the update, I found LTE service all over town.
p.s. If you really want to understand and track the LTE rollout, go to S4GRU.com, which focuses on this matter exclusively and knowledgeably.

Tmobile Lg Nitro 3g/HSDPA Possible?

So i was walking along the road and then when i looked at my phone i saw a H above my signal bar and i screenshotted it. It switched between H and E, then 3g also appeared, but i couldnt get a shot of it because it disappeared quickly.
so now im wondering is 3g/hsdpa possible on a lg nitro using a tmobile sim because when i look around the forums people said only edge is available.
It's possible that you were roaming onto the AT&T network due to getting no T-Mobile signal for a brief period of time. The phone won't be able to get 3G on T-Mobile's network though.
It works!

That has to be why. The Nitro definitely doesnt support AWS bands for 3G/4G.
Just wanted to issue in case anyone wanted to save some money. I live in Kansas city and just started Wal-Mart family mobile service and I am getting 3g and hspa signal on my unlocked att p930. That being said, it does look like the data speed itself is throttled to 1mb/s up and down. I'm wondering if it's possible to change that by messing with the apn...
Sent from my LG-P930 using xda app-developers app
You definitley were in an area with 1900 band being utilized. It's been rolling out around Annapolis MD and Alexandria VA areas. Love it!
10mbps down.,
here is the map
http://www.airportal.de/
Yes it appears that it's deployed throughout Kansas city and even about an 80 mile plus radius of the city. My device picks it up but family mobile have the speeds throttled down to .9mbps up/down no matter what. Very frustrating seeing the H symbol and not being able to break 1mbps anyone have any ideas?

[Q] force 3g on GS3

I recently rooted my GS3 and i have been trying to figure out how to force 3g service on it any help? since i can only pick up 4g in certain areas im tired of the EDGE 2G.
Im pretty sure you cant, seeing as hspa+ is still technically 3G or WCDMA. So I think your stuck with Edge for now... Until T-Mobile does more service upgrades in your area... Don't worry, I get crappy service wherever I go, and I have the worst service here at home... Should have went with Sprint...

You could try, but AT&T uses the same thing "HSPA+" which is really 3G, but they still call it 4G, and that's what would show up on your status bar (it would still say 4G), so I don't know if that'll work... You can give it a try though. I'm actually going try it our right now, and see how it works. I'll keep you posted. :good:
Have that issue too and don't count on them upgrading anything anytime soon. Just wait till your contract is up and make that switch

I guess you can take the 4G plan off your phone and be throttled down to 3G speed... That's it.

New prl for sprint that allows 4g lte connection

I was reading this in a different place. I flashed the newest modem (ma4), which works well. I'm on prl 25010 but I believe the one mentioned was 25013. I show the 4g lte available but my phone has never connected. I was wondering if I have to update prl also to be able to connect to lte. Also heard the new airave (mine is on the way) broadcasts lte 800?
Sent from my SPH-L710 using xda premium
Airave doesn't broadcast lte I have one and it only does 3g sadly but if your not getting 4g lte when you are in an area where it is available then maybe you should go into settings then hit more settings then tap mobile networks and make sure you are on CDMA/LTE and if you already are toggle it back to CDMA reboot then change it back to CDMA/LTE and reboot again and see if you get LTE if no try updating your data profile since prl are associated with 3g internet and roaming only I believe it shouldn't matter but I would always update both just in case
Sent from my SPH-L710 using xda app-developers app
I'll give that a try after work tomorrow :thumbup:
Sent from my SPH-L710 using xda premium
Actually, the PRL can enable and disable LTE, but I don't think there's a single PRL for the GS3 with LTE disabled. 800MHz 1x is a different story. Each new PRL since about 25006 or so has been gradually adding more 800MHz markets.
Also, even if an airave did broadcast LTE, what's the point if it's still using your home internet connection? You may as well just connect to WiFi. And as for LTE 800 on an airave, that's even more useless because the GS3 doesn't support 800MHz LTE, only 800MHz 1x.
I have 25012 now from last night.

Since 25012 I cannot connect to LTE now. Was working great on 25010.
It is probably a limiting PRL to reduce data traffic in certain areas for maintenance issues or Sprint released the wrong PRL like when I had an evo 3d a year ago.

I'm on 25012 and connect perfectly to LTE and getting great reception and signal.

Technically the PRL does not effect your normal cell service with sprint towers only if sprint releases a bad PRL. Now if sprint has a local roaming agreement with another cell site company it would affect your service. This is my understanding I maybe wrong.

LTE makes it's way to Boston.

I started having problems with data this morning and noticed LTE 4G was popping up then dropping signal, in order to maintain coverage I had to deselect LTE in network settings but the point of the thread is to make it known that it is being implemented today for Boston.
