Yeah, it seems like eCSFB is being ascribed here as the bogeyman to any LTE connection issue. If you don't have a CSFB connection on a Triband device, even toggling airplane mode will not get you back to LTE. If you are having CSFB problems on a Triband device, your only relief is LTE Only mode to get to LTE.

 

If you are constantly being pushed down to 3G from LTE where you can regain LTE with an airplane mode toggle, either it's the network deciding to push you off, you have a poor quality LTE signal or your device had an issue. CSFB is not the culprit if you can toggle airplane mode and get back on LTE.

 

I am an AT&T customer. When my LTE gets worse than -108 RSRP on my N5, I constantly get shoved down to WCDMA. I have to cycle airplane mode to get back. That's the network settings deciding that. In fact, I typically have to stream something to keep my LTE signal from shunting me down to WCDMA.

 

In many places, ATT WCDMA is fine as a backup. But at my office, it's not. B4 ATT LTE at -110 RSRP runs at 20Mbps. Whereas the WCDMA I will get handed off to will be 10-200kbps.

 

So I understand your frustration. But in my instance, and in most likely many of yours, the issue is not CSFB.

What about calls that simply never go to the phone? One of the reasons i moved one of my lines from sprint is that I would get a lot of calls going straight to voicemail. Have you seen issues where the phone won't hand off from LTE to CDMA? Thats the only thing I could think is the issue because my signal was usually good.

I haven't had seen this issue since moving one of my lines to AT&T. It rarely stays on hspa for more than a minute after coming into lte coverage.

Here in the DC area I see ATT sites with 4 antennas. Usually two large ones and two smaller ones. Haven't seen any that are all the same size yet.

Battery life has been horrible for me. Hard to cross 3.5hrs screen on

Where in the DC area are you that the service is unusable? I'm starting to see LTE all over the place. Get B41 at my home in Alexandria.

Best of luck at at&t. Hope you continue to follow Sprint and that it gets better for you in time.

Just ordered my G3. Moving from an S5 to G3. Decided to go to AT&T though, since sprint is unusable in my area

Not likely. The roaming limits are the same. They just now are enforcing them essentially. There are people on contracts affected now. I doubt Sprint will let them out because they want to roam more.

I guess it was smart to move away from contracts as this might've been a way to get out.

Well I'm over my limit and I have no text..

no mms on my s5 either

Are you using Google Voice integration?

I stayed in Arlington for a few days a couple months ago and b25 seemed to be humming along okay. 3G was slow as molasses during peak times, but I wasn't surprised there. I have a history of falling back to 1x when the 3G congestion was too bad, though I haven't needed that option since getting a tri-band LTE phone. I think band 41's capacity will probably definitely help ease congestion, though I didn't get any while I was there

Data isn't so much the issue, but it's the extremely late texts and calls that never come through. B41 is excellent in the city and parts of MD you can find it. B26 is there too but needs tuning.

I've seen att adding new antennas in my area recently. Glad they are because I may I have to move to them since my Sprint is still unbearable to use here.

I hope they can get it together because I'd return.

I would say the gain is greater than that. The free space path loss difference between Lower 700 MHz and SMR 800 MHz is right around 0.75 dB. In the real world RF environment, that difference probably gets elevated into the 2 dB range. Not a huge gain, but a measurable one.

How long has Wi-Fi calling been active on your account? Less than a few days, then you may want to do this from the dialer screen:

 

##72786#

And let your phone re provision itself.

Edit: still won't send

That's incorrect. MMS and SMS both work fine on Wi-Fi calling.

Just a heads up. watch out on Wi-Fi calling, you won't receive any MMS messages so if you use those a lot you may have to turn off Wi-Fi calling then turn it back on.

It is because your in washington dc, even in chicago the b26 isn't fully configured. Right now the 800 lte is on low power setting and will be turned up when all the other sites are turned on and not have interference from other towers

i doubt thats the case here simply because the signal is comparable to ATT's 700mhz signal from the same tower

I can't tell if its Sprint's 800 lte that seems very fragile or its a bad radio on my s5.

Here are some of my findings:

1. often my s5 will not handoff to b26 when the b25 signal is degrading; i will watch it get to about -115dbm then drop to 3g. An immediate airplane toggle in the same location will get me on b26 with a good signal coming from the same site (Verified by looking at the GCI). this gets frustrating because my phone ends up being on 3g a lot more than it should, when i have a substantial amount of b26 around me.

2. I compared my s5 to an s5 on ATT in my basement. ATT's 700mhz and b26 on sprint will make it to my basement. the signals are coming from the same site (ATT is one rack higher so i understand why it would be a few dBms higher). Anyway my s5 on b26 sits around -104 to -106 while the ATT s5 was at -102 to 104. I simply placed the phone on my lap and the sprint s5 immediately drops to 3g but the ATT one gets to about -108 to -110. It just seems like b26 shouldn't drop that easily

so far i haven't really been impressed by b26. i'm hoping my phone is the issue though. Have you guys seen anything similar?

Thanks for the responses guys. The camera still seems a tad slow with image stabilization off

 

As far as B41, I use Signal Check Pro to see which band I'm on. So far no B41 in Houston for me. How do i get to the engineering screen? Through ##DATA#?

yeah for me signal check doesnt show b41 on my s5

dial ##33284# then 777468 as the code

Do they ever plan on adding MMS support?

My guess would be Ericsson. They are horrible around here.

Why is the ecsfb handoff so unreliable? I missed a phone interview today because my phone never received the call. It happens a lot.

Thanks for the reply.  I've seen a lot of people complaining about it on the Sprint forums.  The Sprint replies are saying change the phone to be CDMA only until the issue is resolved.  I didn't know if it was a market thing or if it's like that everywhere.

I'm in a spark market as well and i get calls that never come through as well as late text messages. they've told me to put it in cdma mode too.
