Not sure whats going on, phone just lost internet connection...

Well for some reason my phone has just lost internet connection, still shows an H but doesnt sync with anything, cant send emails, cant go on the web, wont even download the correct time...hopefully its some sort of network issue or something but i doubt it...kind of frustrating, hopefully just a small hiccup
edit:
after 5 resets or so it finally came back at around 5pm yesterday
worked great through the night, then this morning no connection again, every once in a while it will connect for about 10 seconds but at speeds of about 100kbs, its been about 3 hrs since its gone down. Talked to my gf who also got the phone yesterday, hers works perfectly
Ill wait until the red one comes into a store and ill either replace this one with a red one or a black one

Just did a factory reset, still no connection, the guy forced me onto a new sim card, i wonder if that may be it

Yeah, I had to get a new SIM card too even though the one I had worked perfectly fine in my Nexus and then in my G2.
When the guy first put it in, I had no data connection at all. It took a few restarts and a bit of time on the charger until I had a solid data connection.

what wierd is mine was working perfectly for the first couple hrs but havent been able to get it to connect since, when it first turns on it says "limited service" and doesnt even find a phone signal for a while...i think this one is going back unless something happens in the next 2 hrs before i get out of work

On network provider click on apn and delete the one undwr t mobile ..start with a t I forgot. Lol. After that select the t mobile on top and done

yeah already did that a few times, ill let it just sit for a while and see if anything changes, sucks because i had almost everythign setup, linking fb contacts with normal contacts is a pain on this thing, it just suggests tmobile and gmail contacts but not facebook, at least not for me so it took forever

It's called telkila I think. Delete that one by pressing menu then delete. Then ofcourse select the t mobile one left

already did that a while ago, still no go when it does work its slower then edge, more liike gprs, too slow to even connect to google servers to let me log into my gmail

same problem here. it shows the "H", but there is no connection. hopefully the update that went out corrected it

I would definitely recommend using the new SIM card that came with the MT4G. I compared it to the one that was in my Vibrant, and there is alot more of the gold chip on the new one. I hope the update fixes your issues with the no data thing. I haven't really experienced this yet.

Same thing happened to me... Data was fine for the first day, woke up this morning and no data connection... Kinda pissed about that!! Will try a new sim card and see if that works...

What its that Telkila APN?

i think you guys misunderstood me, I did get a new sim card. started working around 5pm yesterday and worked until about now at 9:30am it stopped working again. I got the update so that definitely doesnt fix the problem. Im def not reformatting my phone again...this issue is annoying, still shows "H" for speeds yet i cant even go on google.com

I don't even get the H anymore... no sign of a data connection at all...

Well its more annoying that it says "H" yet doesnt connect, that seems like false advertising, i think mine actually may have data but its at the speed of maybe a 10th of GPRS because if i search something in google and put the phone down for 5 min the results will sometimes show up...awesome 4G speeds

did you call T-Mobile?

Have you run a speed test app on it to check (I am also assuming uyou have good 3G/H connections on another device)?

gfs mytouch doesnt have the issue
Havent called tmobile yet, my gfs mytouch had a scratch on it brand new but they were out of black ones, so they told us to come in when more come in stock and i originally wanted a red one, im going to go in there when they at least have more black ones

I am having the exact same issue. Started having problems earlier last week, intermittent at first. Then yesterday it was completely losing connection or saying it was connected but not doing anything. Went and got a new SIM, worked for most of today then stopped again.
I'm chalking it up to a defective phone, sending this one back. I was even lucky enough to get the good screen, don't really feel like rolling the dice again.

Your gf has the same phone, did you try your SIM card in her phone?

[fixed] Internet problem on sensation?

Hi,
To be clear: Internet is not the app, not over Wifi but over 4G/3G/H etc..
I got my sensation 3 days now and there seems to be a issue with the internet connection.
Mine keeps requesting data but it doesnt get any data back.
Apps like internet browser sometimes work and sometimes they dont (loading google), the weather app says there is no internet connection and manage to sometimes get the actual weather.
I tried restarting it serval times but no success..
Internet does work on my HTC Hero.
Edit:
Found the problem, had to enable data roaming..
Odd thing that it works sometimes without roaming tho..

4G internet issues
I am having the same problem with my internet, though enabling data roaming did not correct my problem. Internet and web based apps work fine over WIFI, but will randomly work over 4G. Is anyone else having a similar issue?

I get a severe lag now and then when connected to 4G - seems to take a while for the connection to initiate. I've tried the "fix" posted in another thread, but that only seemed to resolve the issue temporarily.

It seems like location may have something to do with it as well. The tower closest to my home is where I experience the most issues. Though my G2X or my fiance's vibrant work without any issues.

That could contribute to my issue. I seem to live near a cell dead zone.

Theres a few threads open on this issue. There doesnt seem to be a permanent fix yet, but it is extremely annoying.

Same here, my connection would send data but winter recieve sometimes. Kinda annoying. Hopefully, htc addresses this problem soon.

Same issue - across multiple handsets
Hi, it's been a while since I posted in XDA but this issue has been a regular one with my T-mobile service, across multiple devices. I have searched far and wide for anyone else seeing this exact problem, and finally here you are. I hope this helps other users:
1) Purchased the original myTouch 3G; approx 1 year with zero connectivity issues. Loved it, exceptional for its time.
2) Purchased (upgrade) myTouch 3G Slide at launch. Following 3-5 months saw This issue with outgoing data, but no incoming response. 60/40 the internet would respond or not in any application (web, streaming, podcasts), it was a real crapshoot. Assumed the problem was isolated and performed a few master resets. Zero apps installed and continued to see the same issue. Decided it was either software or radio related and called T-mo for advice. They suggested a replacement unit after standard troubleshooting (re-seat SIM, master reset, check that you have substantial signal).
3) New MT3G Slide, same outcome. Called back. Finally received a reasonable suggestion: get a new (free) SIM from T-mo as the one I currently had was slightly older. Was sure this was the issue as the rep sounded very confident when I explained the situation. Received new SIM!
4) No change, issue persisted. Following day called T-mo and had a 'ticket' escalated to engineering dept. Was assured I would receive a call from eng. dept, but no such luck. Bothered by this whole mess and lacking in answers from T-mo, I sold the Slide and upgraded to the G2X.
5) The issue once again reared its head! If the stars were aligned and I did get In/Out data, it was 11KB/s (90kbps) tops. Ex: 5MB podcast would take 0.5-1.5 min (30-90 sec) to download prior to issue, now 10-15 min. This was with no apps installed, 4 bars of signal, 4G status icon, across multiple geographical locations, and fingers on both hands crossed. It was about this time I suspected that somehow T-mo's network was throttling my account. But, I had never used more than 1GB in a month, and they assured me I was not being throttled. A serious WTF was had
6) Realizing there were bigger problems in the world and finally at wit's end, I returned the G2X and am waiting patiently for my contract to expire in July, while using an old Nokia candybar in the meantime for calls and text only.
7) July: move to new carrier or stay with T-mo (if we can figure out what this issue is). 8 year customer, need internet on a smartphone though.

I am having the same issue, and have gone through the same steps. New Sensation (exchnaged mine twice now) followed by new SIM, tried the *fix* posted, turned on data roaming, and still nothing. I have talked to Tmo several times, and they are supposed to be checking the towers in my area, an engineer is supposed to contact me in up to 72 hours. The Evo 3D comes out before my 14 day return period, so I may just jump ship if this problem persists. Hoping to find a fix though, as this phone is amazing when it's on Wifi

Some issues with the infuse

I have been going round and round with att on this issue. My infuse will bounce between hsdpa and umts signal every 30 seconds no matter where i am. They believed the issue was with the phone and replaced it issue still happening. Then advised that it was a network issue and opened a ticket with the "network department" who advised there were no issues in the area. They then removed and re added my data plan with the issue still occurring. Any ideas would be greatly appreciated

It's normal to be connected UMTS. You will only get HSPA when you are actively streaming data up or down.

Is that issue causing data connectivity issues?? On my first Infuse it would show me with 3-5 bars of signal, but when I tried accessing data on apps like the Market, Facebook, or stock Web Browser it wouldn't connect and would give me an error instead. AT&T doesn't know why that was happening. They eventually told me to exchange my phone.

It is and i get the same error it says network unavailable. This is the second "4g" phone this is occurring on

Wow, I had the Atrix and that was happening to me with it as well. I don't remember if it went away after I updated the firmware on it, but I had other minor issues with it as well so I returned it and got the Infuse.
I've been trying out my 2nd Infuse and it seems that it doesn't have network connectivity issues like my prior Infuse, but I've noticed it does start acting up when I use the stock web browser. Maybe the whole issue is being caused by the browser!

I am taking mine back today it cant sit on HSPA+ for more then 30 seconds at a time and this is where a cell tower is almost next to my house and i can see it.

Well that sucks, because they haven't flipped the switch in my area yet. So, I won't know if my phone has this issue till they do

I've been streaming on Pandora for 2 or 3 hours without an issue. My network type switches between UMTS and HSDPA constantly, is that normal?

After working with tech support they feel it is an issue with the phone as it is not locking on to a tower signal. I was also informed that it not a common issue but has been seen with a few of the infuses sounds like a bad batch of phones may be floating around

Man that sucks!! I started having network issues with my 2nd Infuse last night. Today I tried searching the Market and it just kept loading till it eventually gave me an error! I guess Best Buy has the bad batch. What sucks is that the rep at Best Buy almost gave me a hard time when I told her I wanted to exchange it due to network issues.

Spoke to AT&T again and the rep told me that the update isn't for any network issues and that she hasn't heard of any problems with the Infuse so she advised me to either get another Infuse or return it and get some other phone.

Hello,
I'm a new android user and I got the Infuse today. After reading this thread, I tried to see if my Infuse was having the same problem. I noticed when I'm not using data, it goes in to UMTS. However, if I start browsing then it'll go to HSDPA, would this be considered normal or defective?

Not sure if that makes it defective but it happens on mine. Does it have issues loading websites?? Every once in a while when I search for something on google or enter another website my phone won't even load the site and when that happens I try an app that uses internet, Market or FB, and it won't load and finally give a connection error. AT&T doesn't know what causes it.

Congrats on getting the Infuse and moving to Android!
You're really lucky to start your Android experience with such a great device.
Switching from UMTS to HSDPA is totally normal. The battery would die very quickly if the radio had to maintain a constant HSDPA connection. The default is UMTS, and when transferring large amounts of data, the phone should automatically switch to HSDPA.

I haven't had that problem yet, but I've really mostly been using wifi to surf, but I guess I should stop so I can figure out if my device is defective. I'll let you know if I have any issues.

As an experiment, try downloading the app "Net Ping" from the market and set it up to ping every 3 seconds or so in the background. Now if you check your status, it should maintain a constant HSDPA connection.
Hmm...now I'm wondering just how quickly the battery will die? Time to find out.

[Q] Is this the data issue everyone is having?

Is this the issue everyone else is having? Just got the sensation and am having data problems but no posts I've read describe exactly what I am seeing on my phone.
In the notifications bar, "Mobile Network" is constantly cycling between "On" (1 second) and "Turning on..." (5 seconds). It never stops and I get no data on my phone. I have not had any problems with wifi.
When I first got the phone, before porting in my number, it worked fine and speedtest showed 6Mb down. The first t-mo rep said they manually connected me to the tower and that worked for a few hours. I'm in the Baltimore area and the coverage where I am it really good.
Called T-Mo again today and they told me what I've read in the forums, it's a software issue and there is nothing that can be done until an OTA update. They had me run the cyphering fix, etc. but nothing works. They are at least crediting me the data cost until it is fixed...

When did you port your number? have you tried switching the "network operator" setting to GSM only and testing that? If it works better on GSM only, it may be an ssue with a tower near you. I know that tmo is having issues with data on roaming towers atm, are you in network?

I am in network with good coverage here in Baltimore. Got the phone on Monday, ported numbers that afternoon.
On GSM only the mobile network still cycles the same way, only 2G keeps popping on and off in the notifications bar instead of 4g.

[Q] mobile network disconnects and gets stuck "turning on"

Hello all, i have had my HTC sensation 4G (on Bell) for just over a month and a few days ago i started losing my connection to the network intermittently. Super annoying. Anyways i tried deleting some recent apps, figured that might be the issue but nope didnt help. It happened about 3 days in a row until i finally did a Factory Reset on the phone. It worked fine for a bit and then began stopping its connection to the network. Anyways super frustrating, i read some forums about tunring ciphering on and off, i tried that didnt work... needless to say im chapped.
Sorry for the length, but basically wondering if anyone knows how to fix this as its to late to return the phone and i have read through similiar forums on other phones

sorry to hear abt ur problem. i experienced the same thing but i think mine was triggered when i installed juice defender. it would turn off mobile data when the screen was off and when i went to use the phone, i didn't have a connection. i uninstalled the app and did a power cycle and that seemed to fix the problem after i went back into settings and checked the box to turn mobile data on.

This. The phone seems to have trouble (on the stock kernel at least) when switching data from wifi only to cell when cell is turned off. This happens to me when I use wifi calling. The solution I came up with was to connect to a wifi network then turn on mobile data in the quick settings manually. Works every time for me.
HTC really needs to fix this.

Under mobile network in wireless settings, enable always-on mobile data.
This somehow fix my connection whereby it hampers with JD app by not turning on when it needs to.

Thanks for the help guys. I did also recently install a "battery optimizer: in Droid Utilities or soemthing like that, although i did a factory reset. ill try and do a full battery cycle like you mentioned and see if that helps

so the phone worked fine on the weekend, and even friday and i thought it was cause i stopped using a non "htc" charger and got rid of Android Utilities. but now its Tuesday again and like clockwork at 1pm it just stops connecting, if i reset it i get network for a few minutes and then boom out again. Very frustrating mid work day to be without my phone for hours on end. Dont know what to do.

Are you using WiFi at the time it goes out?
Sent from my HTC Sensation 4G using XDA App

No i havent been, not allowed to use private phones on the corporate wireless, but so far i havent found a problem with it switching between wi-fi and H+ while at home.
I have a feeling that Bell Canada may be updating the network or something in the area but they havent said anything both times i called and i asked. so who knows. Its just to much like clockwork for me to think it would be the phone, but who knows.

So i believe i have this figured. I talked to tech support once again yesterday and i point blank asked if it was network problems he said no (3rd person from bell to tell me this) then reccomended i get a sim card change if that didnt work he said send the phone in for repair.
So i went to the downtown bell store talked to the girl, explained why i needed to replace a brand new sim, and she told me that it was because Bell doesnt have towers downtown they share the Telus towers, however because of network bottleneck bell users get less priority and thus i cant use my phone... Not only is this unnacceptable for a phone company to not provide service DOWNTOWN in a major city but having denied it multiple times forcing me to troubleshoot for hours and spend almost an hour talking to bell representatives...
NOT HAPPY. Bell - 5 in my books, lucky my contract is up in a few months and i can switch to telus where i will be able to get signal downtown...
