Why no 3G or LTE while in a phone call? - Sprint HTC One (M8)

If I remember correctly I could use Data while on the phone on my M7, why am I not able to on the M8? Running ViperRom and have full LTE service but can't talk and use data at the same time...

The same is happening in S5....

It's no fault of the phone, Rom or anything like that.

There are threads about this here already. A search should yield results.
The bottom line is that this is not currently possible on the Tri-Band LTE devices on Sprint's network.

[Q] When 4g comes out for Captivate will we have to get new phones?

Can we just flash the LTE Modem or will we have to get new phones?
our phones do not have the required hardware to go 4g. i could be wrong but i doubt it. but who cares, by the time at&t actually gets a real 4g, we should all be ready to upgrade.
LTE and HSPA are different. As long as HSPA is pushed then we can go to the max of the phones hardware.

Was your old EDGE speed phone capable of getting 3G speeds? X-(
Of course ypur going to need a new phone with a 4G sim card.

For 3G/4G you need to talk tech not blanket terms it would be easier to know what exactly you are asking.
HSPA+ LTE are the competeing tech one being a new tech (LTE) and one being an advancement of current tech (HSPA+).
Captivates can do um 7M using HSPA (double check gsm arena or the wiki or the manual for the numbers) so any upgrade to the network the device will top out at the max speed the device can support.
Sent from my SAMSUNG-SGH-I897 using XDA Premium App
Max speeds for HSPA are theoretical. TMO said they would push it up to and over the 50M level while currently upgrades to networks have it at 14-21M though because of the way it works you will not get those speeds real world.

Verizon 4g lte on Sprint!?

I know this doesn't sound possible hell I Dont believe it myself but I am in LittleRock Arkansas where Sprint has NO 4g, I'm up here at work bored so I flash the 1000 Verizon prl, I unlock my SIM card (don't think that mattered , I didn't put a SIM card in). I forced roaming on my phone and I about had a heart attack when the 4g showed in my notification bar!! I thought it may be wrong but I ran some speed test with and without it. The catch is I lost voice. How is this possible?

Highly doubt it... Verizon is operating LTE on 700 mhz (the latest article I saw was that in 2015 they will plan to shift some EVDO to LTE on 1900). The Sprint HTC One only supports LTE on 1900.
Just because Sprint hasn't officially announced LTE in that area doesn't mean they haven't been doing the update. They have a ton of location that have spotty (and even complete) LTE coverage that aren't even officially on the LTE list.
The n.ispsn is something new also.

Lol! Look I'm not saying it's undoubtedly Verizon's 4g, I'm just saying that normally I Dont get 4G even when forcing roam. I flash the modded Verizon Prl still no 4g. I force roaming and boom 4g and no voice.

I've played with some different PRL's some allow 4g, some don't. But on all the ones that allows it I can't download apps from the app store. Updating my profile loses 4g until the reboot.

Force roaming causing 4G detection isn't anything new, actually. If you put the device into LTE mode only, it achieves something similar. The device would much rather stay on Sprint service if at all possible and will take a weak LTE signal if it can (even if it would normally prefer a nearby Sprint tower providing 3G coverage).
The speeds you've posted are in-line with a Sprint 4G test/slow rollout and would frankly be rather laughable on Verizon's 4G network-- if we get around the obvious hurtle that it is not physically possible for your phone to pick up Verizon's LTE, full stop.
Eliminate what's impossible (by hardware) and we have a series of at least possible alternatives.

Oh, *that* one. I used to use it all the time until it stopped giving me Verizon 3G. Now all I get with it is 1x. I would try it, but I'm running 4.3 now and don't want to nandroid back to a Sense ROM just to confirm that it's not working.

Sprint 4G on initial release in an area or an a tower is very wonky. It's off and on, slow and only works at a short range. Just be patient and you will get it really soon. They just activated it in a couple areas where I live also. They tend to put them near Sprint Corp stores.

Why is it unbelievable that Sprint is bringing 4g to Arkansas... They HAVE TO do the NV update on every single tower that broadcasts Sprint Signal. It is cheap as dirt to just add the LTE hardware into the NV station once the NV upgrade is completed. This is a nation wide requirement since they are about to do some wonky ass things on the 1900 MHz PCS bands (when they start to reallocate their allowed bandwidth to different techs, it is an across the board FCC license).
I'm from Arkansas too and have been keeping up with the 4G there because that's where I travel to every chance I get. Jonesboro has sprint lte and it's been planned for little rock and Fayetteville to get it for months. It was only a matter of which day. I'm surprised it took them this long. But it was expected. I'm so happy to hear this wonderful news

[Q] 4G issue on HTC one

Dear All,
i had some issue with my HTC one device. i bought my HTC one model PN07120 and the seller said that it is supporting 4G LTE. in the setting of network i had found GSM / WCDMA / LTE i choose it and it is not working with the 4G LTE. i tried my sim card on other device and 4G working with out any problem. i had also do the APN setting and it is not working.
in my area the coverage is perfect and i use my sim card on another device which is supporting 4G LTE and it works. my provider is Omantel and they using frequency range in 18000 MHz.
however, i had tried some rom to upgrade my device to 4.2.2 jelly been and i successfully upgrade my device and still i had problem with 4G LTE.
i had use RUU to return my device as stock. now it is running on 4.1.2
is my device supporting 4G by knowing the model?
is it possible to have in the setting LTE option and the device not supporting 4G ?
if my device is supporting 4G ,how can i change the carrier frequency on my device?
our country's 4G frequency range is 18000 MHz
my device is making me crazy :crying:
please help me

I would hope not either. I love mine, but you could try rooting it and putting a custom Rom on it. There's s chance it could he an issue with your kernel too. And if that doesn't work you can unroot and just send it back.

IIRC Omantel is in the middle east. I'm not sure where you got the phone, but I believe you actually want a stock phone who's MID is PN0710000. This seems to be the appropriate model for Europe/Middle East which has LTE (4G) support for 800/1800/2600.
The PN0712000 supports LTE on 700/AWS. This the the current model I have over here in Canada.
Hope this helps.

no more simultaneous voice + LTE with Kit Kat

I updated to the latest OTA and I now don't have simultaneous voice + LTE. I know that the new tri band phones with Sprint Spark lost this feature but I didn't think the OTA would break an existing feature. Anyone else experience this??
First off, wrong section. Secondly, there is no way for that to be possible. When I was using the Sense 5.5 ports, the LTE signal would disappear on call, but the devs confirmed it was still working. We never found out why it happened, but data & voice on LTE will always work hence why everyone SVDO was dropped.

The EVO LTE & S3 generation of phones were the only SVDO phones. S4 until now CAN'T do voice over 3g. You'll only get voice/data on WiFi and/or LTE!
I have noticed that since the update every-time I end a call I get the no data message and it takes 20-30 seconds for it to come back, rather annoying actually.

Can get LTE and 3G but not H+

Hey, I ran a sense 6 telus nandroid on my bell phone so I could have sense 6 but since then I've been unable to get my H+ internet back. I imputed the apn info manually and was able to get lte back but it only switches between lte and 3g. Never get H+.

still haven't seen H+ come back on my phone. Seems like the signal isnt as good as it used to be either.
This is the radio i have: 4a.23.3263.28_10.38r.1157.04l
would changing the radio possibly bring H+ back.
Trying to go back to stock with hboot 1.56 has been nothing but problematic for me because i cant get S-off to work.
