My Amaze is having some serious Mobile data (4g/2g) connectivity issues. The problem is this:
1. When turning the screen on, the notification bar shows no mobile data connection, regardless of how many bars I have. Mobile data connection is always enabled under quick settings, but for some reason the phone still can't establish a connection for quite some time, or until toggling mobile data on/off a few times.
2. After finally getting a connection, the phone has further problems connecting. Even though 4g/3g/2g icon is present on notification bar and mobile data is enabled in quick settings, using browser will return only "page not found" errors, and apps will not function properly due to them not having a network connection (foursquare and spotify most especially). Looking at the 4g icon on the notification bar, I can see the "up" arrow flashing as if the phone is sending data, but the "down arrow" is dead as a doornail, not lighting up or receiving anything back. This happens regardless of how many bars I have.
3. On the rare occasion that the phone's mobile data connection does work, it's super slow and acts more like 2g than 4g. Simple web pages take anywhere from around 30 seconds to a minute to load, and spotify cannot stream a song without having to buffer constantly.
Does anyone know how to fix this issue? Or had experience with it? Just in case your wondering, I haven't gone over my 5gb data plan yet (see attached image).
Issue resolved.
Apparently this problem is a combination of 2 glitches:
1. When upgrading to a new phone, despite how much data you used in your plan during the billing cycle, on the T-Mobile My Account website, the widget which shows how much data you've used will only reflect the data you've used on the currently activated device. Before I upgraded to the Amaze, I had exceeded my 5gb limit on my Nexus One and was being throttled by T-mobile to lower speeds. My next billing cycle doesn't start until Dec 27th, so despite the fact that I've only used about 70mb on my new Amaze, the 6 gb I already used on my Nexus One still counts for this month's billing cycle even though the T-Mobile website doesn't reflect it.
2. When throttling, the Amaze, which by default is set to WCDMA/GSM auto, is supposed to automatically switch itself off of 4g and only allow 3g/2g connections. It doesn't. For some reason, it stays with the 4g connection even though the connection is, at best, intermittent. This is the cause of the "page not found" errors and app network errors I was having.
So, for anyone else who is wondering how to remedy this, the fix is simple. Go into Settings>Wireless & Networks>Mobile Networks>Network Mode, then tap "GSM only". This will cut off the problematic 4g connection while still allowing for 3g/2g connections. While noticeably slower (especially where I live, since the Florida panhandle only has 2g and 4g, no 3g), the mobile data connection is solid. Have yet to have any connection errors or experience any intermittency. Still, can't wait until the 27th when I can test out the full power of the 4g connection.

Hi,
I just got this white Skyrocket phone with 200MB data plan.
I heard that when connected to 4G, the phone uses data allowance from the data package, whereas if connected to WIFI (like at home), the data usage doesn't come off my AT&T data allowance.
So I want to disconnect from 4G and connect to my WIFI when I am at home.
At the store, the just told me to make sure that WIFI is showing as on on the top bar (or when you swipe that bar down). They said if WIFI is showing on, it means that the phone is using WIFI connection.
However, I see that at the same time when WIFI is showing on, the "4G" icon is also showing on and looking active! So- they are both looking active! That's why I wonder which connection is my Skyrocket actually using?
It looks like the data I use on WIFI also comes out of my data plan because the data packet is on.
So I had an idea, went to settings-wireless-mobile networks and unchecked "Use Data Packet".
When the above was unchecked, 4G icon disappeared and I could see only WIFI icon on the top bar, which would be good - however, the problem is that now I cannot connect to internet. (I turned the phone on and off- no change)
Does it mean that there is no way on Skyrocket to bypass AT&T data allowance and whether I use 4G or my own WIFI, there is no free internet access on this phone?
Or is there something else I can do to make sure I am connected just to my WIFI and data is free?
I would appreciate your help.
Thank you
This isnt the skyrocket forum.
wrong forum.. don't know about Skyrocket.. this is Galaxy S II SGH-i777
But you can always check by running some speedtest if you know how fast your wifi is.. or just go to settings and make sure it says connected.. or turn off your data when you're not using it.
Grab a program like traffic monitor. It'll show where your apps are getting data from and how much they're using.

Sometimes apps like the market actually use your mobile data connection so both icons will show. From your phone dialer enter *3282# and hit call. It will send you a text letting you know how much data you've used.

I'm having an issue that has been bothering me. I run Etrade Pro with streaming data and charts, and when I leave my home, it does not automatically cut the wifi and switch to LTE or 4g. My app stops and says there is no data. This has happened a lot and I wonder if there are some settings that need to assure that mt cell signal automatically kicks in when Wifi cuts out.
ANother problem is that if I approach an area where there is wifi, the phone connects, and i usually get a data issue again.
I also got the same problem when i stream a video while on wifi and then leave the wifi zone, so I know it is not an Etrade app specific problem,
Any advice would be appreciated. What I am having to do is manually shut off wifi and then restart the app when the 4g kicks in, and I know the phone is designed to handle this for me.

I'm not sure this is something we have control over, I was reading over a white paper qualcomm wrote on the matter: http://www.qualcomm.com/media/documents/files/3g-wifi-seamless-offload.pdf
Our phone is 3GPP R8 however, I'm not sure at&t's network supports dual stack mobile IP, so therefor the handoff between wifi and 3g would have to interrupt data.
WHat bothers me is that I just came from an Iphone4 and the iPhone switched from wifi to cell, and my Etrade App kept running. There may have been a momentary lag, but i didn't have to close the app and start it again.
Let me look into it more when I get home. At work youtube is blocked on the company network so I can't test if a video continues between handover here.
WHen I leave my home and know that I am out of wifi range, I still see the wifi symbol on the home screen but it looks like there are no bars of strength. It's like the thing is still trying to draw data through wifi that is well out of range.
Frustrating.

So if the wifi symbol is on the status bar that means the phone is still connected to the wifi (or at least thinks it is).
I was not able to reproduce your problem with youtube when I was home. I started a video on wifi in my home, and then walked out the front door and down the hall until it lost the connection, the wifi symbol disappeared and it just had to re-buffer a little bit after it switched to LTE then the video continued.
Rooted stock ROM Verizon I605 running 4.1.2.
I was in Korea for the past 6 months and just got back the other day. Before I left, I never had any problems, but since returning, my wifi and data are on at the same time, and it's causing me problems. Here's what's going on:
If I just have mobile data on, everything works as it should. If I turn on Wifi, it will connect, but the data connection will also remain, and my internet speeds will become spotty. If I turn on mobile data and just try to use wifi, the Wifi icon appears (with the orange/green arrows indicating activity), but apps don't connect. Facebook automatically tells me "No Internet connection," Opera won't load pages, Google Talk can't sign in, etc. If I turn mobile data back on, things work again, albeit slowly.
The strange thing is if I turn on Airplane Mode and then turn it off, leaving data off, my wifi will work 100% normally. If I try to turn on mobile data again, I get the same issue.
While I was away, I replaced the SIM card so I could use my phone over there. I messed with some APN stuff thinking I would be able to get data on my phone in Korea, but that didn't work out so I returned my APN settings to default. I have a feeling that's the source of my problems, but I have no idea how to fix it. I tried restoring my APN settings to default through the settings, but that didn't fix it either.
Any help at all would be appreciated!
If it helps I have been seeing the same thing. I'm on CleanRom 3.5 (Verizon Rom base) and PB&J kernel. It seems to be hunting between them even when in strong wifi signal.
Interestingly enough it's not doing it right now.
I'll keep a closer eye on it now.

In my case, it's a constant problem (unless I manually go into airplane mode, like explained). It doesn't work sometimes and not work other times.
I'm trying to use wifi at home, so signal strength isn't an issue either.
Here's my problem, the data connection will periodically not work (3G & WiFi still show and strength is not a factor, also no 4G in my area). My current workaround is to enable airplane mode and then disable it, if this does not work then I restart the phone (rare, but it has been necessary).
I have a completely stock VM CDMA ROM, S-ON, not rooted, all system updates have been applied, etc, since up to this point I've been content with what I have. When I go on to the internet with an app (shows connected) and I'll get an extended blank screen from the app I'm using before it tells me there is no internet connection. I'm at a loss as to what is happening, though I have noticed that it frequently occurs when I unlock my screen.
If I go into developer settings and switch off Mobile data always active (in an attempt to save a little power when the phone is on Wifi), I find the phone often doesn't enable data when I leave Wifi. I have to cycle airplane mode to make it do it.
Anyone else finding the same bug? Or even using this setting?
I've had dropped connection issues since day 1, with airplane mode being the only way to restore my connection. And this was with Mobile Data always active set to on.
Who is your Carrier??
Have you noticed similar issues even with mobile data always active?
When I go to building with no cellular and come back outside. The phone doesn't automatically reconnect to cellular, leaving me with no service. What a strange bug.

EE in the UK. Works fine almost all the time so far if I keep mobile data active.
Vodafone Romania, toggled the setting off in dev options as soon as I got the phone. Data switching works fine still.
Try going into the testing menu (dialer code *#*#4636#*#*), select phone information, select 3dot menu on top right corner, try switching around between Europe and automatic. I'm my case ,selecting Europe presented various weird connection issues , biggest of which was that the phone refused to connect to LTE unless I used "automatic".
