MT4G Connection Failure - myTouch 4G Q&A, Help & Troubleshooting

Greetings!
I have a Samsung Captivate, so I'm a less familiar with MT4G issues.
My sister (who lives 700 miles away from me) texted me today. TMobile has reset her phone twice in the 2 weeks she's owned the phone because of a "connection failure" message related to her data network. She says it doesn't work more than it does work. She says reception is a non-issue because she has pretty much full bars.
Anybody have similar experiences. I've checked pages of threads but can't find anyone else with the same problem.
My gut says she's having 4G connection issues related to either the antenna or (more likely) the modem/software.
I'm thinking she should just take it back and get a new one, but I figured I'd check for a simple fix first.

T-Mobile UK problems

Is anybody else having connection problems with T-Mobile today? I've had no reception for hours and my friends are experiencing the same issue. We're all in Glasgow so I wonder if it's a local problem or not.
When i scan for networks i get "your sim card does not allow connections to this network" when i choose t-mobile.
My friends have their reception back and i have only had it back once in the past few hours until i started getting the error again.
Bill has been paid etc so im not banned or anything.
Got connected with the 'Use only 2G' option. Have read on other forums that T-Mobile's 3G servers are having trouble today.
This sucks!
This happens all the time mate.
I'm in Greenock near the T-Mobile building with the big 3G transmitter, makes no difference, sometimes it just goes tits-up and only way make communication is to switch to 2G.
pain in the arse.
Had the same sort of issues as well, thought it was localised to the transmitter closest to me as it happened a few months ago and took T-Mo around a month to fix. Seems to be working OK now, though
just as a tip, you may want to consider using Twitter to search for any outages with your network provider.
i'm on O2, and live in an area where i'll get a decent connection in one room while getting a bad connection in another (usually my bedroom!)
When I get connection issues, I use Twitter to see if it's a UK-wide issue, or if it's just problem in my local area. I find it to be more informative in this situation than any kind of forum, since it's about as real-time as you can get.
And the best thing is, you don't even need an account to use the search! http://search.twitter.com

Rogers 3G network

Hey guys, I just wanted to see if anyone else is having a longer waiting period with the Rogers 3G network lately or if it is just me. I've been noticing that my phone has slowed down quite a bit when browsing the internet or using an application that requires data on the 3G network. My wi-fi is fine, just the 3G. It takes between 45 secs to 1 minute to retreive the information. I had called Rogers and asked them to reset or refresh or whatever they do down there, but didn't seem to help.
Now if it is just my phone, maybe it is some application that is using up the processor or data, but I don't have that many applications running in the background other than weatherbug that constantly uses data.
Any suggestions would be helpful.
Thanks
What happens if you run a speedtest? the app by Xtremelabs is good.
no issue here. i use mine on a daily basis between pickering and mississauga, and as long as i have at least 2 bars of signal strength my magic is very fast over 3g
Thanks guys for the quick response. I think I found the problem. I had called Rogers support again and they said that it is due to my sim card being a 2G one. I need to replace it with a 3G. Hopefully that will fix the problem.
Thanks
I too have been having internet/email issues since last Thursday using my Treo 750. The symbol toggles between 3G and H and usually does nothing but comes back with an error message saying something like 'cannot find this page...'. I travel between Oakville and Concord every day with the same issues. The phone worked perfectly in Brantford last night...so I don't think it's a hardware issue. The tech support guy grabbed a treo and tried and was able to connect on EDGE....not 3G.
I tried my sim card in my sons Motorola Risr and it works perfectly....on EDGE. They tech support guy said they were having issues with 3G last Thurs/Friday, so I'm wondering if whatever they did last week is affecting some older phone models (I've had mine for 1 1/2 years now). Not sure if I can (or if I want to) configure my treo to connect via EDGE instead of 3G...
Anyone having the same problem?
Very odd indeed. I got my new sim card but still doesn't fix my problem. At least I'm not the only one experiencing the same problem. As far as I know, the 3G and H symbol are he same thing according to rogers tech guy, correct me if I am wrong. I'm going to call again today to see if I come up with anything.
Just got off the phone with Tech Support again. They are sending me a new Sim Card, but from the sounds of it, that's probably not going to fix the problem. He WAS going to do a free hardware swap until he discovered the phone is out of warranty. Then it was basically "oh gee, three year contract, one year warranty...tough luck".
Yep, the G and H are the same thing. Since mine is switching back and forth, he said the phone is hunting for a signal.
When I asked why the phone worked perfectly in another city he couldn't give me a good answer. I have to go back to Brantford tonight, so I'll get a chance to repeat the experiment.
Listen folks. It has nothing to do with your SIM card, nor your phone. The reps at rogers, I for one, ASSUME it could be the sim card, but really, most of the reps cannot differentiate an incompatible SIM with a compatible one, so they send you out a new one anyways, just to get you off the phone because they really don't know what the cause is and they have no hands on the status of the networks and network problems other than what is posted in library by the actual IT department, which do not directly communicate with the centers.
To sum it up. Rogers 3G network is garbage! and that DNS issue is not isolated to the metro area, it's here too in Newfoundland. DNS resolution is extremely slow, even with OpenDNS, which means it's their switches that are garbage and most likely being bogged down. Rogers thinks they had solved the problem by throttling the 3G bandwidth to ~3Mbit and the upstream to less than 150K, (My assumption), however, that isn't working.
From my guess is that the request is sent to Rogers networks, which cache that request then caches the pages and sends it to your device, making it appear you have a fast connection.
Anyways, sometimes I find the EDGE network a lot faster..especially in the DNS resolution area.
"It has nothing to do with your SIM card, nor your phone"
My feeling exactly. It just seems a little too coincidental that everything was just fine until they had a network "issue" late last week.
So, being a mechanical guy with very little knowledge of how a these things actually work, is there a way for me force the treo750 to use the EDGE network?
Never mind, I got a hold of a guy at Rogers who seemed to know his stuff. He told me to get the latest OS from Palm and then how to go in and set it up for EDGE. We'll see how that works.

I love ripping on Rogers for being crap, they are, but the network is downtown Toronto is far from crap. And it is not throttled. I have had repeated speedtests reach 3900kb/s with the average around 3100kb/s. Thats not too bad considering the crap they put up with in the states on AT&T.

True, compared to the 3G in the U.S I would agree that Rogers has an edge, 3G here in Newfoundland is still in it's infancy, well still is everywhere. We just got 3G last winter I believe.
what newfoundland has 3G?
now hell really has frozen over (ha)

semi-random network disconnections

I have a mytouch currently running TheOfficial TMO US v1.7.1. It's been reflashed with the latest 32B radio. I've been having problems with the mobile network connection randomly dropping out, meaning it shows an "x" instead of any bars at the top. While in this state, it won't receive or make calls at all. I've tried unroooting, had the phone replaced by tmobile, gotten a new sim card, and still get this problem.
The most common time I see it is when I unplug the phone in the morning after leaving it charging all night. I'll glance at the screen, see it disconnected, and turn airplane mode on then off to reconnect. A few days ago, it happened in the evening and I'm guessing remained disconnected for about an hour, since I got a voicemail and didn't receive the notification until I did the airplane mode toggle later.
I don't know if this is a problem with the T-Mobile towers, but I don't think so since other phones don't seem to be running into this problem. Reception in this area is generally very good and I've never had this disconnection issue before over several different phones.
Is anyone else experiencing anything like this? Any suggestions?
ETA: Sometimes I've tried going into the mobile network settings and running the carriers search, and it gives me the message saying the SIM cannot be registered on the network, then the message stops appearing after a minute and the phone connects just fine.

Found the thread: http://forum.vodafone.co.uk/index.php?showtopic=25796&st=0
Most of these guys seem to be describing exactly the same problem I'm having. Are any other US T-Mobile users seeing anything like this? According to their coverage map I'm in a very solid voice + 3g data area.
In the meantime, I'm gonna turn off 3g for 3 or 4 days and see if these outages continue. I'll post an update in case other people run into this issue.
Another update:
After two days of trying "use only 2G networks" my phone didn't do this disconnection thing even once.
Something similar also seems to be posted as an android bugreport, although he doesn't go into the problem of "your sim card does not allow a connection to this network": http://code.google.com/p/android/issues/detail?id=2845
Another data point: a family member just purchased a mytouch today, on the same T-mobile plan but different line, and to try it out I set it up and watched it, and within 2 hours of being connected to the 3g network, it switched into the disconnected mode, and refused to register the sim card on the network.
So far, 3 phones, two different SIM Cards on two separate lines, and identical symptoms on each...
I will be trying an ./adb logcat at some point to see if I can catch the problem and complete that bug report.
For the record, I'm having this exact issue. Phone was fine for about 5 weeks, now I'm getting the same problem you describe. Any news or ideas?

Since I had my phone replaced for a faulty back plate, and the replacement phone having 0007 hboot fw - I haven't had this issue at all. Two weeks and counting.
Wife returned her phone under warranty for continuosly dropping signal and got supposedly reconditioned replacement handset back with 0007 hboot. This would seem to confirm this is the new default rom version.
Folks in U.S. on 0005 have confirmed they get the dropped signal issue, so I would also presume that between 0004 / 5 and 0007 a fix has been made.

Error Code 67 while roaming driving me nuts

First off, I have NOT made ANY attempt to use the phone as a WiFi hotspot, and I do NOT live in a 4G area, so don't tell me that's my problem and send me on my way
About 11am PDT today my phone started giving me Error Code 67 (Data Call Failure) whenever I try to access the internet or data services from my office (my office has an 850 MHz repeater so I roam in the office). When I am outside or not in my office and the phone picks up a Sprint signal, everything is fine. As soon as I come back inside and my phone switches to roaming, Error Code 67. I've had two calls with Sprint so far...They're updating the provisioning servers or some such thing at the moment and are going to call me back when that's completed.
Has anyone else experienced this today or recently and if so did you find a resolution? I can't easily take the phone back to where I bought it and have them fiddle with it in person as that's 100 mi away.
Thanks!
I've had the same issue too. See it mostly when traveling and the signal strength changes. Not to much when I'm in one spot.
It's quite annoying. I turn the display off and on hoping to pick the signal back up. Makes me think it is a Sprint network problem especially since I've now confirmed someone else has the problem too.

Well, they've got me fixed up again. Also while I was on the phone the gentleman helping me out received an interoffice message stating a server responsible for doing profile updates (Device Configuration message) on the EVO had gone down, so they're failing right now.
I have been getting it as well. I thought it was the roaming hack but I don't believe that is the case. Think it's just something on Sprints network.
I have gotten it too on both of my EVO's....I guess it's not just me

Yeah I read through that whole thread and it seems a fair amount of people have had this happen today. And as I wrote in that thread some service at Sprint related to sending out new PRLs and profiles to our phones went down as well.
I had the same problem yesterday my 3g suddenly went out with the 67 error but 4g still worked. I called sprint and they reset something on their end and after programming itself it w.ent away and my 3g data speed saw a nice speedbump
I've had this issue a few times with my Evo. Every time it has happened to me, I've had little or no signal.
What I think is happening is that the phone begins to authenticate itself with the data servers but then I lose reception, which causes the authentication to fail, hence the error message.
I _think_ I've had this happen on my Hero too.
yeah, (don't quote me on this, i may be wrong) i think error 67 is in regards to no data hookup, and if your phone is set to not get data during roaming, or to dilly dally about it (maybe roam guard?) (check settings > wireless and networks > mobile networks), it'll give you that error
I too had this issue for a while today. It was annoying the crap out of me.
same thing happened to me today, for some reason i wasn't able to get anything but a weak roaming signal at work all day. i called sprint, they wiped my phone and i still wasn't able to do the profile/prl update. i was able to do it once i left the building, of course i had to start with a blank slate on the phone. i'm hoping that after the updates i get a better signal in the building, otherwise i can't keep the phone and will have to return it for a (gag) iphone. after 3 days with a vastly superior OS that would be a tough thing to do.
Mine is def. not the Roam settings... That's the first thing I do is turn off Roam guard, call guard, special roam ring...etc. due to me having almost no signal at work.
I had this issue when I changed to the Alltel PRL. I rebooted, then ran the PRL update. It took a while to do, but once it got the Sprint PRL everything was fine.
-Midnigh7-
I had the same issue yesterday around the same time as the OP. Seems that maybe Sprint was having issues. Anyway, phone is back working and roaming today and even roaming 3G in the DC metro which is Verizon and was never Alltel AFAIK, so that's cool. Actually, some stations have Sprint in them, but others are Verizon and I had 3G Roaming in them today, so I was pleasently surprised, hope it sticks.

[Q] Orange UK - 3G does not work..

Hi all,
Wonder if you can help me as I'm beginning to lose it with this phone..
I've not had a decent connection since I bought the phone back in september. Basically a 3G signal means no connection. Nothing happens, no data. When its on the 'H' sign it works really well but it stays on H for like 10 seconds before switching back to 3G.
I've googled this problem and it seems I'm not the only one with this issue. I've changed the network settings, and even tried various radios to no avail. I have good 3G coverage in my area so there shouldn't be a problem at all. Even in central london it doesn't work. It's too unstable and virtually unusable..
Can anyone suggest any other possible solutions to this please?
Thanks
Talk to lennyuk about this
He got on well against orange and can tell you the story of what's wrong
I had this problem before! Orange just sent me a new SIM and it was all sorted !
Thanks chaps,
I've just PM'd Lenny!
alex: I'll ring them up and ask them to send me a new one if it still doesn't work. I'm sooo not looking forward to explaining to them what the issue is...haha
Ah, I had this problem, and it left me 4 months without data thanks to oranges stupidity.
Anyway a short term fix will be to dial *#*#4636#*#* and go phone options, then change your network in the drop down box to 2g only (or similar can't remember the phrase it uses)
2g still works all the time.
As for the long fix, you will need to speak to orange and demand to speak to "high tech" support they can fix it (well they did for me eventually). The problem they said was that my phone was connecting to both an old tower and a new "super tower" they orange UK are installing across the country, this confused the phone and messed up its data connection when on 3g, as it was trying to pull data from 2 towers at one time.
Orange eventually forced me onto one tower (or so they told me) and for a large part the problem was solved from there on in.
You do have to remember as well though the Hero has some 3g compatibility issues with Orange's existing network (again stupid orange), this is something that can never really be fixed.
Orange support can be very helpful if you speak to the right people, don't be afraid to tell them to put you through higher up straight away.
Hope this helps.
Thank you very much for the informative reply Lenny
I'll keep you all updated.
Just a quick update..
I had 2 weeks of stable connection up until a few days back! It had been fine ever since Orange fixed the 3g/gprs problem after it went down for everyone. Probably due to the low traffic? (see below)
So I phoned Orange yesterday and explained my problem and asked to be put through to the 'high tech' department. However, after a while being on hold, the 1st line support advisor said she'll call me back asap as the techies were busy. She called back about 20min later, just as I popped downstairs for 30 seconds! Anyway, she left a message explaining the problem. Turns out that my area has 2 masts both of which are running at full capacity, and there's not enough bandwidth for everyone, hence why my connection has been unstable. She also said that they're going to be upgrading the capacity on the 18th which should fix it.
Another thing she mentioned was that, next month when orange and tmobile merge there's going to be more masts for our phones to connect to - more coverage and bandwidth. You can sign-up to trial this on the orange website.
