Evo 4G Always Digital Roaming and Slow Data (Help?)

Precursor: I recently purchased an EVO 4G online and had it shipped up here to Canada and after some phone calls/fiddling I managed to get it onto the Telus network. I can make and receive calls and send/receive sms with no difficulties. Data seems to be working (I get the 3g icon with up and down arrows and can surf the net), and mms seem to be sending.
Which brings me to the issues at hand:
1) My 3G speeds are super weak (between 100kbit and 140kbit down and 100-600kbit up). If I stand in the same place and use my Touch Pro 2 (they both show the same number of bars) I get 800-900kbit/sec.
2) My EVO 4g -ALWAYS- says "Digital Roaming". I've updated the PRL with the latest Telus one (off the internet) as well as the one off my Touch Pro 2 but see no difference. I don't incur any roaming charges, but the phone always thinks it's roaming.
3) Last but not least, I'll often get a pop-up that says Data Call Failure Error Code 67. Sometimes I'll go for hours without seeing it, and sometimes it'll pop up every 5 minutes.
Any input/insight is welcome!

P.S. If you want tips on how to get your EVO onto Telus, drop me a PM.

I will love to have feedback, as I get the "data fail" error often while roaming...

Update: It seems that when I force my phone to use only EVDO, the Data Call Failure Error Code 67 goes away. Perhaps related?

Just following up on my own thread: It seems the Error 67 is because my 1x data login details are incorrect (a side effect of the sprint radio).
Still wondering on the other questions, anyone?

Xan, how did you get HTC Evo to work on Telus? I'm almost at the point of returning this one that I got from Texas. I have tried for 24hours to no avail.
Please help!!

I just had the same issue. Luckily I downloaded an app off the market called 2g 3g switchand it resolve several issues I had including yours. There are three options one of them is the cdma NAM switch in which you could select NAM 1, another option is to leave in automatic, and third if you have any 2g and 3g switching issues you can select hybrid. Note after switching wait probably 5 minutes and sometimes try again,also you may have to reset.

[Q] Is there a way to set your Evo to run on Evdo(3g) (##3282#?)

My phone keeps going from 1xrrt to 3g(3g roaming area/rural) I've tried all PRLs same results. So I heard about the ##3282# settings. within this is there a way I can put Evdo only ? Kinda noob at this so I'll ask before going ahead

Update: I went ahead did the 3282 number and ESPT mode pops up. I choose Edit. Then i clicked on Evdo and HDR ONLY instead of Automatic. Now when I check to see what network I'm on it says Evdo_A wooo. but still it's only 1 or 2 bars. So I guess the reason why it drops from 1x to Evdo is because the weak signals? but Verizon map shows they have FULL 3g coverage here.(philadelphia MS) Owell I guess I'll play around with more settings and see what I come up with, if you have any help that would be great for me.

[Q] 4G Connects but "Service Not Available" ??

My home is well within the Sprint 4G coverage area shown on the coverage maps. When I turn on 4G (from the Settings screen) it connects to the "Sprint Network" and obtains an IP address (Signal strength = Good).
BUT:
None of the applications which require network access (browser, Market, email, YouTube, etc) can connect. They'll open up, but they can't access the network. If I uncheck Mobile networks in Settings > Wireless & Networks and then re-check it again, it reports "Service unavailable" despite the fact that the 4G Settings screen still reports Connected to Spring with "Good" signal strength and I still have an IP Address.
I should add that the phone has been doing this since I got the phone in November, but I figured it was due to the "unofficial/testing" status of the 4G coverage. I also installed the new 3.70.651.1 update hoping that it would fix the problem, but it had no effect.
After telephone support ran out of things to try they issued a Ticket # and sent me to a Sprint repair location this morning. That location couldn't test the phone on 4G because the store isn't in a 4G coverage area so they just replaced it with a brand new one (not a referb). So I get it home and try it on 4G before I make a single configuration change and the new phone does exactly the same thing as the old one: Good 4G connection but no service.
Has anyone else experienced this problem? Did you find an answer for it?
Thanks!
Pete
Note: All apps seem to work fine when I'm connected to 3G.

Additional info:
For the record, switching back to 3G after trying 4G results in the battery dropping like a stone. aLogcat reveals a flood of those damned <DC Connect> failures going on in the background. Thankfully, powering the phone off and on clears the problem until I try 4G again.
Two things of note:
It doesn't matter whether I use the 4G widget or the Wireless & networks screen.
Removing the 4G widget has no effect.

Why data connection lost and why reboot fixed it?

Hi,
Using GNex, stock JB 4.11, Wind Mobile Canada, $40 plan, unlimited data & Canada wide.
Please excuse in advance for the novice questions. I am not yet familiar with Wind Mobile. The customer support is too long and submitting a question to their website required around 5 days to get an answer which is generally irrelevant in my short experience. Hope some expert users here can share some of your knowledge.
Last week, suddenly during a phone conversation, the phone became totally disconnected voice & data. The next morning, the situation didn't improve, so I rebooted the phone (power off / on). Then the phone could connect to voice, but no data (gray icon instead of blue). I stayed with no data for 3 days. During that time, I tried a few reboots, changing various network settings (APN, Network Operators, Data roaming, etc.). None of that worked, then I made another reboot and suddenly everything is back to normal (no roaming and data OK).
Q1. Signal strength variation: what is the cause that makes a signal vary? For the same location, sometimes signal changes from 3 bars to 1 within a few minutes.
Q2. What caused a network to black out temporarily? That's what I got last week during the entire night. The reception icon is a black outline triangle (no voice, no data). I purposely disabled roaming, I admit a network could have some issues, but I have hard time to admit that a disruption could last 12 hours. May be the issue is my phone? It was not rebooted since 7 days.
Q3. How often should I reboot the phone? By reboot, I mean power off/on. I hope this is the correct term. Is it possible that a frequent reboot help the phone to be more responsive? I tend to think so because all the network issues I got were magically fixed by reboot.
Q4. Why would a reboot fix a data connection issue? In my case, a few reboots on day 1 didn't fix. Many network settings changes didn't reconnect data. Then finally another reboot on day 3 fixed data connection.
Thanks in advance for any help.

Welcome to the Nexus and its crap radio. Try turning off 4G, once I did that I never lost signal again. With 4G on I get disconnected from the network randomly throughout the day

How to turn off 4G? Wind Mobile operates on AWS network 1700/2100 MHz (UMTS band 4), and HSPA+ for data. I believe it is not 4G. On the phone Network Settings, there is only an option "Use only 2G Network" which is not a good option for me. If I enabled "Use only 2G Network" the phone shuts off data and changes to roaming mode.

just set ur nexus on airplane mode for a second..
then disable the airplane mode instantly..
u ll gain ur net working widout reboot... )

Oh wow, that's a cool tips.
I hope someone can answers my other questions, I like to understand the "how things works" side.

Any number of influences. A microwave, air ionization, temperature, humidity, output from the tower not consistant, and plus just the variations of the phone. Going by bars is a bad way to gauge anyways, it could have only dropped signal for a split second but it doesnt update the bars frequently so it would appear to be low signal longer than it could have actually been. Your phone works by line of sight, picture a tight wire from your phone to the tower, anything that crosses in that line reduces signal.
Q2. What caused a network to black out temporarily? That's what I got last week during the entire night. The reception icon is a black outline triangle (no voice, no data).

That actually is hard to answer, you would need to contact your provider to see if they have a log of an outage at that time before going into whether it was the phone or not.
Q3. How often should I reboot the phone? By reboot, I mean power off/on. I hope this is the correct term. Is it possible that a frequent reboot help the phone to be more responsive? I tend to think so because all the network issues I got were magically fixed by reboot.
Never unless things act funny. A reboot is usually healthy for operating systems (i know many do not). I personally don't intentionally reboot mine, it usually happens because I'm screwing with clock speeds
Q4. Why would a reboot fix a data connection issue? In my case, a few reboots on day 1 didn't fix. Many network settings changes didn't reconnect data. Then finally another reboot on day 3 fixed data connection.
Like any software there are chance of a 'glitch' where the modem and the driver have issues communicating. Toggling airplane mode off and then back on re-initializes this and in most cases fixes the communication problem. Rebooting will have the same effect. I would only worry if you are needing to do this often.

Hope this helps a little.
I would also contact your provider. They may have an issue with the tower you are connecting to.

Perfectly understood, appreciated very much your detailed answers. Can you please clarify below?

Makes sense. Indeed, when I said "For the same location, sometimes signal changes from 3 bars to 1 within a few minutes". Actually, I mean a room and I was walking/moving so may be the orientation of the phone explained why the reception was inconstant.
Regarding your answer above output from the tower not consistant. Is it possible that the tower reduces its signal strength when the number of users increases? Similar to users sharing a finite band width?

Yes, even orientation of the phone can have an affect, depends how the antenna is set up inside the phone, i havent seen it so i have no answer for that.
ya, as you move around you could have been what blocked the direct sight of the tower, signal passes through nonmetal objects but each time it does, it loses strength depending what it passes through

@OP I also have the same problem, I am also with Wind and had to do force reboot to make it reboot.

Flash the UGLC1 radio to your nexus. I'm with Wind as well and that radio gets me good service!

[Q] Note 2 not auto switching to 4G?

Hi guys, I'm plenty familiar with the Note II having had mine since October release. I'm having an issue where I will be in a solid 4G coverage area (at my home) and my phone will stay in 2G mode.
There is a problem with either the tower or the phone, I'm leaning toward tower because my wife has my old Sensation 4G which is also staying on 2G. Have any of you encountered/noticed that your phone stays in 2G even though you are in a 4G coverage area? For me either on the Sensation or Note II, I just pick WCDMA, 4G pops in and works great. The only problem is that I have to remember to put it back on auto when I leave the area. I looked up and attempted the cell codes for making the phone prefer 4G, but without success there. Also my phone picks up 4G automatically when I'm at work, so again leaning toward tower (but how and why the tower can control this I have no idea).
I also noticed some threads claiming wifi calling would detect wireless networks nearby and disable 4G. I'm leaning towards BS on that because 1. my wi-fi is almost always turned off (true unlimited 4G plan), and 2. when I disable wifi calling all together it still exhibits the same behavior.
I'm running out of ideas - any help is appreciated!

In settings>more settings>mobile networks>network mode:
You should ALWAYS be set to GSM/WCDMA (Auto mode)
This will automatically get you the best data signal available at your location. If you only get 2G in some locations, that's normal. You can try calling TMO support and have them check your address to see if you SHOULD have 4G at that location. If you really want to try to see what is going on, install an app called Open Signal Maps form the Play store. Among other useful things, it will geolocate the towers you are connected to complete with distance and mapped street address.
Where I live I only ever get 2 or 3 bars of 2G data. I use the TMO wifi calling app for all my calls and texting. This is only way I can get reliable service at home.

Thanks for replying vouty. When I switch from auto mode to WCDMA I have 4 full bars. That's the funny part. Speedtest is giving me around 12Mbps down 3 up on average (I live right by the tower - like .5 mile), so there is for sure something strange happening. If I keep wifi on it really isn't an issue, but I prefer to not mess with wifi and just keep it in 4G while at home, but as frustrating as this problem is, the phone refuses to switch from 2G on it's own. Once I toggle from AUTO to WCDMA, and then back to auto - it will stay on 4G. It's almost as if I am waking it up and causing the phone to re-detect the signal.

Cool app, very useful, appears I am on 3g at home. Turning off wifi to see if it changes to edge while using data.
