Apparently there are issues with TB losing 4g or 3g, most commonly when power cycling or at random. A battery pull might help but the only temporary fix I have found is to do a factory data reset which will bring back data services however it is by no means a complete resolve from what I have found. Speaking with a verizon tech I know these issues have been lifted up to fix whatever on the network side is causing this issue. So if you find yourself without data and a reset is not to big of a deal (which for me its not) I would recommend just resetting the device and then refrain from powering down your device until it is fixed
Do a factory reset
That worked well for me.

I did a reset, pulled the battery, and then spent three hours on the phone with tech support. Eventually I ended up tethering to my Evo, connecting the market, and downloading an app called "restart connections." It works very well.
On the plus side, you don't even have to power down the device when you use it.
Just thought I'd let you know about it, as it's much easier and more convenient.
I just got my TB yesterday coming from an EVO and Sprint's nightmare of a network. Phone lost data after about 3 hours and I had to Hard reset. I don't get it. I tried everything else. Airplane mode, pull battery, turn data off and on... ect. Reset fixes it. Love the phone it's WAY faster then my rooted EVO with sprint lovers ROM!!! The power cord hookup on the side is an epic fail tho. You cant use the kickstand with it plugged in!!
I must be lucky, I live in a suburb of Chicago, and go all over the burbs and the city for work, and I have had no signal issues. Actually, I am in my office now on the 33rd floor downtown, my coworker stopped by to check out the Tbolt, and we did a speed test, I got 5800kbs down and 5600kbs up. On 3g, I barely had a signal in my office, and would get 200 -300 kbs down in my office. Win! Plus, I have 2-4 bars consistent up here. LTE is awesome.
It wasn't a loss of signal. It lost internet connection. It would talk and text fine but no data.

This is extremely amusing. Yesterday I spent the majority of the day trying to find people with the same issues I was having and I couldn't so this morning I woke up and I said screw it, its time to do a factory reset and that worked. Today I get online and there are about 10 different sites with people reporting the same thing lol. Anyway OP is right do a factory reset. I tried just about everything else and this was the only thing that worked. For those that don't want to have to setup their phone again don't be too worried about this. The device restores most applications and settings in said applications.
I did a factory reset and it did indeed get me data restored in my house. I'm still confused however because other people in my house have VZW and have full coverage all over the house including the basement which is where my room is. 1 has an HTC incredible, and the other a droid 2. 3-4 bars of 3G no problem. For me though i get mostly 1-2 bars without 1X and sometimes with, maybe 1 bar of 3G if i leave the phone still and dont move it. No 4G. I've tried changing the settings to 3G only, or 4G only and stuff like that. Nothing. I've also switched under settings ---> wireless and netorks ---> mobile networks ---> system select ---> changed it from automatic to home only which some people have said worked for them.
On top of all that my phone thinks im in queens LOL! Im just outside of washington dc. Ah the growing pains of a new phone! Now, when im outside my house... Thats night and day. Phone works perfectly! I get great 4G speeds all over my area. Never a problem. Hopefully VZW is aware of the issue and will resolve it shortly.
Hello i have a stock tbolt... I just rooted and clockwork my question is if I do a factory reset will I lose root or will I have any other issue thanks in advance

Settings > Wireless & Networks > Mobile Networks > Acces Point Names > "menu" Reset to Default. What really sucks is when you are on 4G Wifi hosting several devices and you loose Mobile Network. People look at you and think "looser" while they are mooching of your 4G radio....
Works like a charm. Had to do this on my previous AT&T HTC Inspire.
Im in Philly and had no problems today.......
what a bummer. got the phone in the mail this morning and spent all day setting it up. just had to factory reset to get my data back. tried all of the suggestions in this thread and the other one and nothing would bring it back.
Meh, I hate this. Just got this phone today and no data on it while moms iPhone has perfect 3g. I am just gonna wait for some fix though since don't want to reset my phone every time I turn it off.
At least I have wifi
This loss of data issue is really starting to piss me off. I just spent the last hour setting my phone up again after doing another factory reset. Has Verison even said that it's an issue they're working on?

Take it with a grain of salt but the guy at the VZW (official, not a fake store) store last night said he heard about an upcoming software update within the next few weeks. I highly doubt that, but the guy did actually seem to be on the up and up with what he knew about phones and technology, he didn't come across as one of those "dismissive, just trying to sell you everything under the sun" asswipes.
I sure do hope they get this resolved soon. I have no data in my own house, meanwhile other roomates, all on verizon have damn near perfect 3G coverage inside and hell 3G is good enough for me even though Verizon says im fully covered for 4G. I'll take 3G until they get all that fixed. Just give me something! Meanwhile my old G2 would get full service in house as well. I'm almost stuck having to still use that for a while and i probably will hold on to it for another month or two.
this is driving me crazy - I had 4G the first few days, but then kept getting the cycle 1x, 3g, 4g but with no data most of the time late last week (LA area). Then yesterday I had 4G but no data, and finally got it to connect to 4G after several reboots and cycles. Now it won't connect to 4G at all (in an area that had solid 4G early last week). I have done factory data resets, pulled battery, forced 3G, LTE and both in the service menu, pulled sim card several times, forced home and auto networks and data roaming on and off. I've about had it.
Either the 4G local towers have gone dark since Saturday morning, or my phone just won't connect to the LTE signal. At least with the EVO when I was stationary in a 4G tower area I would get and keep solid 4G and data all the time, and handoffs to 3G were quick and smooth. The radios and/or network in this phone are not ready for prime time.
Same story as everyone else (I've tried everything--phone isn't rooted). No 4g in my area, so I don't expect that. What I do expect is to get solid 3g when my friend next to me on his droid is getting solid 3g. I'm stuck with 1x, and even that goes in and out...
same here. I think it's more of a provisioning issue than an issue with the device.
I'm pretty sure restoring default doesn't fix problem as I tried going from one ROM to the next and all are getting the same thing.

^^
Had this same issue on my X. This is a network issue, IMO. Either that, or Qualcomm has some 'splainin' to do...
so!
got the samsung galaxy 4g the day it came out. i had actually gotten the g2 originally, and 13 days later, this phone came out and after holding it in my hands i had to have it. it was just... sexy.
so the day i got it i was so happy. i ended up paying nothing for it through a weird fluke situation on tmobiles part, which made it even better.
then the troubles started.
in getting the new phone i knew that although this phone boasts the speeds that it does there was no way i was going to get those speeds. i do a speed test. at the tmobile store (1/4 a mile away from a tower on a tuesday afternoon around 2 pm) i get ..... 0.03 down and 0 up.
....k.
so i give it some time to get used to my sim card and my usage. that's when i notice the battery. i had to charge my phone two times a day on light usage. i turn off all synching, including my google calendar and contacts to see if that helps the battery. meh, a little. but i'm still charging it at least halfway through the day, and i am not able to use my phone at work. that means from the time i unplug it ten minutes before i leave for work until 6 pm (11 hours later) my battery is at roughly 20% ... and i've done nothing on the phone whatsoever. i'm super sad about the battery life and still getting sad speed tests on my "4g".
then about a week after purchase more problems kick in.
pretty soon my picture messages aren't coming through. it's giving me messages i'm used to seeing on my iphone, something about the message size being too big to download (sorry, the wording has left my mind now that i am trying to document it all for you guys).
then i start getting no texts. and sending them is a joke. if i have less than three bars (i usually have two at home and my work building) i am not able to send. it will try and give me a failed message. pulling out the battery will usually fix it, but after a couple of weeks of that it gets used to that fix and doesn't work at all.
i go into the tmobile store.
they switch out my sim (which we had done once before) and at this point my phone doesn't recognize the new sim. the rep tells me i broke my phone (even though my phone at least recognized the previous sim) and tells me that i'll need a new phone, offering to sell me one for cheap. i leave, pretty irritated at the dude.
i go to work, call 611, they tell me my IMEI has never been active on my account. we activate it and lo and behold, my phone recognizes the sim (mmhmm). but still sending messages is still a joke. out of 10 messages i can usually get one to send. it's a sad ratio of sent to failed.
in addition, i am still charging my battery at least once to twice a day with hardly any usage whatsoever (what good is using a phone that never has service anyway?). i've turned off wifi at all times, 4g is off, everything synching is off. i'll take out the sim and put it in my iphone so that it's not constantly searching for service (which texting worked just fine on my iphone) and it STILL dies by the end of my work day - i am lucky if i get 12 hours of standby before having to charge it. i condition my battery with no luck.. it still sucks. i root it and set SetCPU to underclock down to 200mhz when idle just to see if that will help the battery. i get about 14 hours of standby on that.
so, after all of this and about two months later, i finally got a replacement phone today. after looking at the back of the new phone and the old one i discover something interesting...
my sim contacts have been broken this whole time! sad!
( i was going to link to the pic but can't since i'm a new user. )
now, has this new phone fixed my issue? well, for one i'm getting 4g speeds at my place (i live in downtown SLC, i should be getting them here!) for the first time ever and have yet to come across a "failed" message when sending texts. only time will tell but mostly i want to post this to let you know.. if you are having this issue this is NOT normal. talk to tmobile. troubleshoot what you need to and get that mother replaced!
(i'll report back on battery life tomorrow.)
Consider yourself lucky. I live in Murray, phone says 4G but my Vibrant pulls faster speeds on 3g. Lol

i need a new city
Vegas here. Even though they say we are one of the new turned up cities I'm still only getting 7mb down and 1.5 up on a typical day.
Here's something interesting though, when I upgraded from my G1 to my SGS4G they were supposed to update my data plan.
Logged into my TMO account and it still shows the G1 Unlimited data. Paying $25 instead of the $30.
My wife has a MT4G and her account did get upgraded to the 4G Unlimited data plan for $30 a month.
Possible my phone isn't going to get higher speeds based on the data plan still in my account? I'm doubting it, but I guess it's possible.

i still have the g1 data plan as well, i wonder if that does have anything to do with it. i kinda don't want to ask though, the 5 bucks a month is small but nice to not pay
p.s. for all interested, my battery is at 48% with pretty consistent usage and synching on all day. schweet!
I would have callers t mobile right away and gotten a new phone overnight. I am not too trusting of in store employees. Most don't know how to troubleshoot a phone.

You can have my city.... except I don't have a city.... it's just a trailer park in the middle of nowhere. But then I get better speed here than I can in the nearest two cities, a ripping 16KB/SEC on a good day, on "AMERICAS LARGEST 4G NETWORK" I spend almost as much time downloading as I do talking to tech support. Then that's another story.
Your data plan will not affect your data speeds in any way.
As for the phone showing 4G and having another 3G device pulling better speeds. The cause is that you are not in a true 4G area. The GS4G does not have an icon for 3G, even if it did, the phone cannot distinguish between 3G or 4G due to the fact that HSPA+ is still 3G hardware on the tower, but provides 4G speeds via software in the base station and the backhaul of the network.
I don't see how you are getting such bad speeds. I live in Kaysville, only 20 minutes from SLC and my average DL speed is usually around 5.0mb/s. The fastest I have gotten over 4g so far is 8.8mb/s.

If you are lucky enough to have a 3 or 4G tower in your area you will likely have good download speed. My download speed sucks. TMO's network is full of holes.... DEAD zones. Even in large areas like Los Angeles, CA. They have a long way to go before their network will catch up with the others.

I will have to do it Monday, cause it only happens when I leave my office building. When I am in my office building I will often go into data roaming through at&t. This may have something to do with why it shows up. But it is there.
If you truly doubt it. Go to the market and download ninja morph. Then use it to make a copy of your framework-res.APK. From there open the COPY that you made. Look in framework-res.apk\res\drawable-hdpi-v4
Do not try and look in the actual phones framework-res.apk. Because it will break a couple things and you will have to re-flash. But if you make the copy it will automatically extract the apk and you can view the files with your computer.

I get the 3G icon on my elevator everyday before and after work.
4g
I always get 4g in the missouri area and I get 13mbps
I don't have cable internet where i live due to the fact i travel to and from class way to much to use it. I tethered my phone via wireless or usb to my computer and run off of the 3g network speeds. I currently switch between CM7 and then new EVO Shift 2.3.3 leaked GB Test ROM. I noticed that i have 57% signal according to opensignal and when i download anything or load web pages they are very slow no matter how many bars i have. My download speeds are usually around 20kbps to 55kbps max Is there anything i can do to increase the net speed of my 3G connection? Or is there a app on the market place that i can use to improve or some how boost my 3g network speeds.
I've noticed a little bit slower speeds using the Gingerbread leak but nothing as slow as what you are experiencing. Have you tried the fix from this thread? [FIX] 3G Upload & Download Speeds
Sprints network for Michigan, Ohio and all its surrounding states flat out sucks I get them speeds daily and all Sprint keeps doing is knocking 20 and 50 off my bills, I don't care about money off they either need to fix their network or that roam controlling app is going to get me out of contract etf free I don't care to pay good money for good service but when I pay 160 a month for 2 lines I would expect to be getting the 3G Sprint lies and says I get,

Ah is that what it was. I flashed a new rom the other day with the sense 2.1 and everything was cool except the 3g data speed. It was taking 5-10 minutes to download a 1mb file so I had to restore my other rom lol. My normal 3g data speeds are over 1mbps which is super fast. I couldnt even browse the web with the leaked build, it was ridiculous.

hey
going to try what one do you guys do "1.17.651.1 RUU (Stock):" or 2.72.651.2 RUU: i dont have 4g here
i believe 1.17.651.1 ruu is the stock version that's already on your phone, for people that want to flash back to stock settings if the new radio fails to perform. you should flash to 2.72.651.2 if you want an attempt at an upgrade. personally, it did nothing on my end for the internet, but voice calls did slightly improve. i encountered problems too, where it would hang on the htc splash screen. i don't have an sd card adapter... so i had to put my micro in my old htc hero, run that as a mass storage unit, delete PG06IMG from the computer, boot into bootloader, delete everything, clean cache, davilk (i think that's what it's called), and re-load from nandroid backup. after that i saw 1.08... in about phone, baseband version so i guess i was successful lol. pain in the ass, but will further test it later outside and stuff... once the heat drops down over her in n.y. :]
Besides the fact that my 3G speeds crawl. My 4G is SLOWER on occaison than my 3G. Lol, why is this and how can I fix? It all started when I first flashed cm7

Sprint Mikshifted 2.1
I was wondering the number i had to enter to access the network settings for the mikshifted 2.1 mod. I tried to enter ##3282# and no luck with that . I noticed that my 3g speeds were 20kbps and its horrible lol. Have flashed the new radio on a previous version of CM7 and Kingdom 3.0 rom and didn't work so hot for me. Anyone have any recommendations?
So I have seen other people with network issues about the phone switching from 3G to 4G and so on and I had some of them but never to this extent.
Normally my house is on the fringe of 4G so my phone will usually stay on 3G most of the time. Yesterday while I was at home I was getting 4G, strong 4G and I was pretty happy about this. When I left and went into a 3G area I no longer get 3G, at all. But when I go back into a 4G area I get it just fine, and im at work right now and have perfect 3G on my galaxy tab but no data at all on my charge, not even 1X. Has anyone else experienced this? I have tried forcing 3G only but nothing happens, its as if somehow my phone is only allowing 4G.....
BTW im on stock EE4 not rooted or anything
EDIT: Forgot to mention that I have had a problem in the past where it wouldnt pick up any network, so I would reboot and all would be well. I have rebooted countless times and it doesnt fix anything....
Its your sim card 100%. Get a new one.
I have my phone forced to 3g as there isn't any 4G around here and several times a day it will just drop 3g for 5-10 minutes for no reason at all. I still have good service but drops the data.
I don't have any solutions, but you're not alone!

Ok I think ill go to verizon today to get a new sim card. Its been over 24 hours and now it has stopped connecting to 4G as well, I just went out to lunch to test it. Hopefully this will help!
I live in an area mostly covered by "4g" LTE. My charge will sometimes connect to LTE in my bedroom, but most of the time it can't. Every time it briefly connects to 4g in my home, however, it does not hand back off to 3g for a good 5 minutes or so. Instead, I lose all data connectivity. I've tried turning data mode off then back on, but it doesn't work. After about 5 minutes or so with no data signal, it'll reconnect to 3g. Does anyone know what could be causing this? Is there a way to fix it without just turning the LTE off (switching to CDMA only)? I get LTE in most areas around my house but apparently I live in a Faraday cage or black hole or something.
This is a 100% stock ROM, not rooted, never flashed any new ROMs or Modems.
Man, I have the same issue. I feel ur pain. I was downloading files on 4G and at around 34 percent, it cut out and went on 1x. Stayed there. And I was outside in a wide open spot. It happens man, I was told there's something wrong that causes the data signal cycling like that. I've tried what u tried also. If u can get a straight answer, let me know too lol. And to top it all off, HORRIBLE BATTERY LIFE.
Sent from deez nutts. Oh, and my Gummy'd up Charge!!!!
The handoff process from LTE to CDMA is still pretty cagey. Fortunately, it's mostly software, so updates should help this process.
I haven't done any research on whether EP1F or EP1H (the leaked Gingerbread builds) are any better at it, but I would have to assume that it's part of the process they're working on with modem updates, etc.

when i was with ep1f the radio worked better for me. i was able to connect more frequently to 4g and switching was hassle free (no time outs). it's possible that the problem is on verizon's side since my cousin, who's on stock, is having the same problems in an entirely 4g area.
You might have a ****ty SIM card.
When I first got my Charge it was very similar to your situation. I had poor 4G connectivity in my supposed "fringe" area. Then a week ago it was losing connectivity from 4G to 3G and eventually stopped getting 3G all together.
I got a new SIM and now I get 4G in places where I only get 1 to 2 bars of call signal.
And I also stay on 4G a lot longer. Almost never does it switch over on long downloads or streaming vid.
PS: HAHAHA "long downloads". Sometimes a 300MB download will take much less than a minute depending on where it's coming from.
It must suck to make believe you have fast data. Right, AT&T? HAHAHAHA WiMax!!!
