I recently received my t8697 mozart purchased online, and happily tore my rogers sim from my blackberry and put it in. Configured everything, it all looked ok, it detects the 3g network, but for some reason if the connection meter in the corner says "3G", it cannot connect to the network, any data related activities stop, error messages pop up etc.
However, it occasionally ramps up to an "H" and everything flies! it seems to be if i'm using something like the web browser (where i'm assuming it has a couple of retry attempts), it automatically pushes it up to HSDPA after a minute or so, and as long as i continue to use data it will stay that way. if i stop, it falls back down to 3g, and i can't do anything. if i'm in the market place or an app where it may not retry, once it detects no data it just errors out and it never gets to HSDPA.
i've tried doing a hardware reset, configuring via the HTC connection setup app, but same issue. Any ideas? is this a hardware issue because it's switching between 850 and 2100 (not supported)? is it something i can call rogers about, or something i can configure on the phone?
i see my 7 Mozart switch to 3G when i'm in an area that doesn't have HSPA access, but i never have trouble connecting to the at&t network. mine has worked flawlessly from day on on the 850 mhZ band. don't know that this helps you. might be time to try another SIM card as well... good luck!
i picked up a new SIM from rogers today and same issues, is there a way to force 850mhz only? maybe it's just a radio issue, i'm wondering if one of the other roms with a newer radio revision might help, or if it's actually a hardware thing. it's pretty frustrating, my EDGE speeds are actually faster, at least it loads consistently.
download the htc connection wizard from marketplace and run the rogers setup, it sounds like your APN is not set. I had the same problem when I first got mine.

that definitely helped, when i did a hard reset, before i could download anything i had to disable 3g, download it on EDGE, and then run it before i could do anything :S. it's a lot better, still a bit off and i get random no data coverage, but i think maybe i'm just in a low 850 signal area. the bars seem to drop significantly as soon as i pick it up.
The telstra model in general seems to be really flaky, flickering images, random reboots and crashes. do all of the roms support all frequencies? ie. installing an asia/europe rom where it's all 900/2100 then disable my 850mhz access because the radio's not configured to support it?
Is it possible to change the frequency bands on the ASGS2? For some reason I am unable to get data connectivity on the 850MHz band in one part of Houston, while 1900MHz works fine. The phone likes to flip between the two, probably because the 850MHz signal is a bit stronger at that location (850MHz = 3 bars, 1900MHz = 2 bars). I'm not sure if it's an interference problem or if the tower is just overloaded / broken.
I tried the ServiceMode menu, but get a RAT selection option restricted message. The sim card removal / hot-insert workaround doesn't seem to work reliably.
I've contacted ATT multiple times in the past 2 weeks and they say it's impossible that there's a problem with the towers and that it must be my phone. I've tried three different Atrix's and an ASGS2 and they all have the same frequency band issue. ATT wants to swap the phone through their mail warranty service, but I'm almost certain it's not the phone based on my previous devices exhibiting the same issue.
Am I taking the right approach here? Would messing around with the band options even help?
You can do it....but only with an i9100 modem...

I couldn't find this info anywhere on xda but I wanted to share this with you all, as the xda community has always helped me and I've rarely had the opportunity to return the favor.
I'm a month into a new G3, and all was well until the last 3 days. About 10 days ago band 41 started showing up with great speeds. I only get about 105-110dBm (1-2 bars) but I was still getting around 20 mbs download speed and it worked great. 2 days ago, my G3 would lock onto band 41 at work and I couldn't get any data. Our wifi is sketchy and I need reliable LTE. After profile & PRL updates were no help, it would bounce from band 41, to 26 to 3G. Back and forth my phone was going band to band trying to lock onto a good signal but kept trying to hold onto the weak band 41 driving me nuts.
So after some research I found a way to disable band 41 & 26 for now until the network becomes more stable. If you are in an area where spark isn't fully baked and have trouble holding onto band 41 or even 26 you can do this. I now have a clean steady stable fast LTE connection at work where I need it the most.
To disable LTE bands:
1. Call or chat with a Sprint rep, ask for your MSL code, its a 6 digit number.
2. Go to you dialer and dial ##3282#, this enters you into a data menu.
3. Tap "LTE", then "edit"
4. Disable any LTE bands causing the issue. I started with 41 but ended up also disabling 26 as it was also spotty and fluctuating.
5. Then hit the back button and the phone will reboot.
You can the re-enable them using the same process at any time. I figure I'll check once a week to see if things are working. If they aren't I'll just disable them again. I would think this would also work on other spark capable devices like the M8, S5, N4, G2 but I don't know for sure.
Thanks, I hope this helps anyone that may be dealing with spotty spark LTE service until spark gets fully implemented.
Goodluck
What are you using to find out what bands your phone is using? Thanks.

You can also see it by using ##debug# and going into LTE Engineering option "Band" will show you. (This is likely only on LG software, not sure on CM/AOSP)
@Macguyver. THANK YOU so much for this!
I'm on the fringe of LTE/eHRPD and just by killing band 41, my reception is finally holding LTE. I've have to put my phone on CDMA just to keep data until now.
I still average 15% cell standby meaning searching for signal, but at least it holds and my battery has gotten better using LTE.
Thanks again.

Thanks for the bit of info. I turned off bands 41 and 25 to stay on band 26. Band 41 stayed between -115db and -123db and band 25 was a bit better but band 26 stays between -100db and -112db. Still not great but much better than band 41. On speed test for band 41 i was getting mostly 0's. On band 26 i am getting about 4megabit down and 2 megabit up. Never any 0's for download or upload. It does slow down but never 0's coming in on the throughput.
I recently purchased an Xiaomi Redmi Note 3 Pro phone (kenzo), it covers all the bands that rogers uses in my area in Canada, I believe.
https://en.wikipedia.org/wiki/Rogers_Wireless
I can connect with the phone on LTE, HSPA+ with no problem, if available. Sometimes, if I am in certain area's, the signal indicator drops to 3G .... it shows a decent signal, but no calls or data can go through.
In this example on the following chart, the first WCDMA connection,my phone only indicates 3G and I can not make a call or use data. When my call attempt is done, it goes back to LTE. Then I try again. Then for the second WCDMA connection on the chart, I am connected as H+, I can make a call and use data. Whenever this phone connects to CID 31072 the problem happens. When I connect to CID 31075, no problem. These are just examples of towers that I reach from my home. I get the same problem occuring other areas.
Any suggestions on what I need to change on my phone? Is my phone making a kind of 3G connection for some reason, which Rogers doesn't support? I have tried everything I can think of, Miui dev versions, CM13, LineageOS 14.1 etc, change Android Radio Menu settings, etc.
Nothing seems to fix this issue.
Any advice would be greatly appreciated!
I have been using Network Signal Guru, and have figured out that the phone will connect calls data on 3g if the band it finds is B5-850M .... if the tower tries to connect to is B2-PCS-1900 the call fails.
I tried to block the use of band 2 with Network Signal Guru, but it seems to still use it when it finds it.
I have since flashed a LineageOS rom and used the Network Signal Guru to disable band 2 WCDMA. The phone has not been experiencing the issue at all since. I am cautiously optimistic that I have found a solution. Still not sure why this band doesn't work here though.
My US model (XQBC62) is has having trouble with 5G on T-Mobile. 5G connects only intermittently in NSA mode.
Sony support says:
I'm asking you this because at this moment Verizon is currently the only U.S. carrier that supports 5G on the Xperia PRO model. The 5G network service is not currently available in the Xperia 1 III model and this is why you're getting that issue. In this particular case we recommend you to check with your phone carrier if there is a way for them either to provide a different network service or if there is a work around on their system for you to use your Xperia phone with their service
...
The Xperia 1 III phone does support 5G however at this moment the only phone carrier that provides 5G service on the Xperia phones in the USA is Verizon and at this moment they only support it on the Xperia Pro model. The phone carriers still working on providing the 5G service on all phone models they support and that depends on their coverage. I would like to give you a different solution however the phone service is covered by the phone's carrier and the best option you have is to contact T Mobile directly so they can further assist you with this issue
...
I would like to give you a different answer Kevin but at this moment the phone carriers don't support 5G service on the Xperia 1 III model and this function will be available through future updates by the phone carriers.
5G isn't all that great yet, maybe never.
More limited range and more obstacle intolerant than 4G. Average users see a 20% speed increase when in range.
Don't sweat it...
T-Mobile has 5G on the 600 MHz Band 71 so their 5G coverage is literally better than their LTE coverage where there's high signal attenuation (trees, mountains, stucco buildings).
It's disappointing to go from an LG Velvet 5G to an Xperia 1 III and start losing signal everywhere.
Does turning Airplane mode on/off get it to reacquire the 4G signal?
May be a firmware issue meaning the phone doesn't react to the signal conditions appropriately.
Maybe disabling 5G if it's possible would yield better results.
I just got a new 4G N10+ in part because of issues like this.

Like I said, coverage and performance is better if it can do SA 5G.
Releasing a NSA 5G phone was forgivable a year ago, but TODAY? It's probably sucking more power by constantly switching between LTE and LTE+NR constantly rather than just using NR all the time like other phones.

Pretty much why I decided to avoid this hornet's nest.
Have you tried switching NSA and SA to use SA only?

That was the first thing I tried after I noticed loss of connectivity without LTE. SA mode disables 5G. I even tried powering it off for a while then powering it back on. Only NSA + SA and NSA work.
I have 5G coverage in Europe (italy) on Xperia 1 III, but it's limited to some cities (not operator) then i switched to 4G only mode.
here operator have NO phone limited 5G, you only need to have coverage
Excuse my 5G ignorance but...I use T-Mobile here in the US. I have 5G all day long if I want it. I rarely use it though because even though speed tests show that 5G is faster than LTE it also uses more battery. Also, there are times that while using 5G web pages load slower and YouTube videos buffer whereas when using LTE I have none of those issues. So while I agree that 5G is more gimmick than anything (for me) I still can connect to 5G without any issues at all so I am not sure what to think about the so-called Sony support answers????

There are two types of 5G.
Early phones had "non standalone" meaning that NR was only a temporary booster. The phone shows "5G" all the time but it's only momentarily connecting and disconnecting NR while keeping LTE on. These phones don't know how to use NR by itself or for phone calls. This sucks battery life and it causes stalls in data transfer.
Modern phones have "standalone" 5G. This means that the phone can use any mix of NR and LTE together all the time, including only NR. There's no switching and the phone can use whatever works best.
My T-Mo Velvet 5G got a huge performance boost in cell data when it received the SA update. Lag and dropouts around town were 100% gone . When walking around town, it's on LTE 2 + LTE 66 + NR 71. It can lose any two of those bands and be fine. It beats any LTE phone in stability. (RF absorbing stucco houses around here)
My new Sony has a MUCH faster CPU but it's a step back in cell performance. It's using LTE 2 or 66 (not both) and switching NR 71 on and off for data transfer. I frequently take it out of my pocket and see that it has no cell reception. Signal Check says it has NR 71 and is trying to connect to LTE.
I'm hoping a software update eventually fixes this. Much like the fingerprint reader crashes, this is a shameful launch for Sony.

Well, assuming you know what you're talking about I appreciate your explanation of why I have stalls in data transfer and high battery use on 5G. Hopefully a software fix is possible and on Sony's radar. I have not experienced any fingerprint crashes nor have I heard anything about that. My fingerprint reader works great all the time. Anyway, thanks for the explanation!
Don't feel bad about "shameful" Sony launches.
Even Pixel's are dropping the ball as well as all the major brands. Too much, too fast...
Android 11 is the worst dropped ball of them all and that comes right from the top leaving the manufacturers with a mess they can't completely rectify. 2021 was a bad year for Androids. Google could have prevented much of this... Android, so secure it's unusable.
FWIW, the Pixel 6 seems to be swilling battery on 5G so most people are just disabling it. 5G was my original reservation on the 1 III, but now it seems less relevant so I'm considering returning my pixel and trying the sony.
Can anyone confirm that 5G radio can be shut down to save battery on the Sony? I'm pretty sure I'm reading that it can be, but want to be sure before I order. If it matters, I'll be on AT&T in the US.
Yes you can choose to NOT use 5G on this phone. I have turned it on/off several times and while speed tests show 5G as faster than LTE ... it uses more battery, and YouTube videos will buffer and web pages load more slowly??? Whereas on LTE none of those issues appear. So for now, at least on the 1 mark 3 - 5G is useless. Sad really but for me LTE runs everything just fine and fast!
Yes, well is any carrier on top of this?
Verizon's 5G rollout is going really... horrible.
T-mobile made this bold offer to boned AT&T and Verizon 5G users.
Anyone else contacted Sony about this? I posted a question here.
If this information is up-to-date, Sony disabled NR SA on all the bands used by T-Mobile.
Sony Xperia 1 III (US) (XQ-BC62) | 4G/5G Bands & Combos
4G & 5G Bands, Carrier Aggregation and Dual Connectivity Combinations for Sony Xperia 1 III (US) (XQ-BC62)
cacombos.com
This is weird because only T-Mobile has good NR SA coverage in the US.
I've tried to get customer service to forward this bug to engineering, but I don't think it happened (at least they provided no way for me to track it). And community support link I provided earlier just doing the typical finger pointing to blame the career.
I did a 5G comparison to a T-Mo LG Velvet 5G that does support SA 5G. The Velvet 5G has 10x the download performance but the Xperia 1 III has 10x the upload performance. When walking, the Velvet 5G produces a stable signal from carrier aggregation while the Xperial 1 III drops and reconnects frequently.
