[Q] 4G LTE will not work in Canada

I am using the 6603 model here in Canada, where most providers has 2600 Mhz LTE support. But I can only get 3G to work. This is what I found so far attempting with two different providers.
1) one of the providers cannot even find 4G when I do a network search, another can find it's 4G LTE access point, but cannot register to it
2) APN are set properly
3) LTE is selected as prefered already on phone
4) we have tried 4 different Xperia Z 6603 units and none of them will get 4G
Any thoughts on this, any additional info needed I can provide.
Thank you everyone :crying:

I'm interested in importing a 6603 myself. It could be that the radio software in the phone isn't set up to connect to just the 2600 LTE band. I know users of other phones have had to flash a different baseband in order to connect to their desired band frequency. But I have no clue. Just spitballin'. I hope someone figures it out soon though. It would make the decision to buy one much easier.

I know, but it doesn't mean the phone is natively ready to use that band on its own. For all I know the baseband on the Xperia Z connects to two band frequencies, one for upload and one for download. I have no idea why it's not working on Rogers LTE out of the box. Hopefully it's just a fairly simple software fix, but I can't say for sure.

I don't think Bell/Virgin uses the 2600 LTE band, so you're out of luck..

Wondering why if I leave my one set to lte only it holds it with no problems but once I change it to the regular settings is mostly on 3g?

I understand if set to LTE only that it "holds onto LTE better" I suppose, but is it usable? Once the LTE gets to around -120dbs on the One it is unusable I read. Sometimes at my work it will be on LTE but the minute I start using and significant data it drops to 3G.

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] No 4g/LTE

Hello. I have just bought a One with Sprint, I tried several Roms and never I Reached 4G in Spain. When I selected LTE or CDMA no data , If I put it in automatic I have 3G or H but never 4g.

Same issue. I know I can get 4G beause when I drive around, my phone has said 4G on it. With that being said, I only get 4G about .00001% of the time im using the network so it goes to 4G when i dont need it. i doubt its my phone its Sprints towers but that really sucks cuz 3G is sooooooo slow for me.

It's probably because your Spanish carrier does not use CDMA or Sprints LTE bands

Are you still getting LTE? If so, you may be on 2600 MHz, in which case your speed should still be great. I only get 1 bar while at work but I'm still pulling down 20 Mb/s. Conversely, I can someone get full bars on 1900 MHz but only get 3-6 Mb/s down because band 25 is so crowded.

On the stock ROM, the signal bars correlate with the LTE signal strength. The easiest way to check which frequency you’re on quickly is download SignalCheck Lite from the Play store. If you see something that says UCF and DCF (up/down center frequency) and the numbers next to them are in the 1900s, you’re on band 25 (1900 MHz). If you see neither of those, but instead see something that says TAC (tracking area code), you might be on band 41 (2600 MHz). I haven’t encountered band 26 (800 MHz) yet, I don’t know what it would say.
The other way is to use dialer option ##DEBUG# and go to the “LTE Engineering” menu to see which band you’re on.
As for your speed test result, that looks like it’s kind of low (assuming it's 2600), and that ping is really high. I use the Ookla app and found that running on the nearest Comcast server gets me the best results.

There's no normal speeds, it all depends on how good the sprint signal is in your area. Good ping number will be that of below 100. The lower the better.

It's all good! I didn't know much about it either, but someone made a thread in another forum to help explain it to me:
http://www.s4gru.com/index.php?/topic/2710-How-the-Internet-Works...--haha
Basically, ping/latency is the roundtrip time for a data packet to be sent from your phone to a server and back to your phone again. A good ping for me is somewhere in the 60 ms (millisecond) or less range.
The maximum theoretical speed for band 25 is limited to 37.5 Mb/s, and I could be wrong, but band 26 might be somewhere in the same range. However, don't expect to see anywhere near 37.5 given that band 25 is so loaded now. You'll likely see 3-20 Mb/s, which is still more than enough.
Band 41, on the other hand, will typically be much faster since it's less loaded and has much more spectrum than the other two. The drawback to band 41 is that 2600 MHz does not penetrate buildings as well. On this band, even with low signal, you should be getting at least 10 Mb/s unless you're in a really crowded area or your signal is really low (-115 dBm or lower).
