TMo: web and talk simultaneously?

Can you browse and talk simultaneously with the myTouch 4G?
In strong 3G and 4G environments, I'm unable to browse the web and talk simultaneously on my MT4G.
This was never a problem on my G1 in 3G settings, oddly enough.
Should I be able to browse and talk at the same time on the MT4G when I have a good 3G or 4G connection?
Has anyone noticed this problem? Any fixes available?
I'm running Ice Glacier 1.1.6.
UPDATE: This dual use is working at the moment. Perhaps I've been in Edge networks or weak 3G for previous attempts.

ANY GSM phone connect to 3G+ connections should be able to talk on the phone and surf the web at the same time.

I have noticed the same issue... hmm was thinking it was a issue with my settings. May have to look into it.

I've personally had mixed results with this... sometimes (in E, 3G and H) i can talk and browse at the same time, sometimes no dice, but anytime I am using the stock Wi-Fi Hotspot all my calls come through and it never breaks my tether.

anyone have any update on this? I can't find anything to fix it.

I recently bumped an old thread from early dec abbot the same issue. It seems many ppl are having the same problem. I too am having mixed results. I will have 3g fine when not in a call, but once I'm in a call, data along with mms function gets killed. However, a few times I moved closer to a window and I would get the 3g icon back. So I can only chalk it up to reception. it seems being on a call somehow effects 3g reception. I don't have a technical explanation for that though.

I had this issue back in late 2009, using a G1 then. TMO was only giving the Orlando area about 800 kbps down, but voice + data should still work. My actual 3g icon would vanish as soon as I got on a call.
TMO opened a ticket to have a field tech check towers, but I never heard anything back.
A coupla weeks later, Orlando had an outage. I went into a TMO store to see what was up and to gripe about the outage. We were given two, free CliqXTs. Shhhh, I said they were GIVEN to us. (and I will stick with HTC devices from here on out.)
Well, same issue. We then put in the NEW SIM, as opposed to using the one I got with my G1 in 2008, voila! My fiancee had the same issue. Swapped her old SIM, voila!
So for me, it was an issue with how the old SIM worked on the network (or didn't work).
Nonetheless, on a GSM network, concurrent voice/data should be possible, so if it's not a matter of just poor coverage in your area, I would go to a TMO store and/or call customer care.

It works for me, even when I use it as a wifi hotspot at Starbucks (Because it's better than their free wifi . I'm able to call and txt and browse the net and receive calls while I am browsing on the laptop. It's very nice IMO

It's weird because it didn't work for me on the stock ROM but it works fine on CM7.

Do you still have a backup of your stock ROM before you went to CM7? If it's "something inside the ROM," then it should be an easy test.
Since the hardware obviously didn't change, it almost sounds like a APN or Mobile Network settings issue. Can you compare your stock to CM7 and see if there's any difference?

Sometimes if you're on a voice call for a while, you'll drop down to 2G. When that happens, your ability to do simultaneous voice and data goes away. If you're mobile data indicator goes away while on a call then this is what's going on. You can verify under the the "Network" part of the "About Phone" screen.
You can mitigate this somewhat by setting your phone to 3G only mode but this can cause it's own set of issues. If your phone wants to move to 2G because of signal quality issues but can't because you have it set to 3G only mode, your call might end up dropping altogether.

So new sim cards solved your issues? Did your data speed/coverage improve at all?
Sent from my HTC Glacier using XDA App

@Phate - In that particular incident, yes, the new SIM resolved my issue. I had the issue on my G1 and then TMO gave us two free CliqXTs to retain us. We used the same SIMs from our G1s and the issue persisted. I called back in to TMO and they recommended using the new SIMs, as they said they'd seen issues with certain "older" ones.
From that point on, we could browse and talk. Prior to that, you'd see the 3G icon vanish while you were on a call. As soon as you ended the call, the 3G icon would come back.
Our speed then was around 800 kbps down, which isn't blazing fast but it's definitely more than EDGE. Once we got the new SIMs, the speed was still at 800 kbps down in the general Downtown Orlando area (keep in mind, this is early 2010). Over the next few months, the speeds got better and better and then we ultimately ditched our CliqXTs when the Glacier became available.
So in my case, Phate, the SIM resolved our simultaneous voice/data - it did not increase our speed, not explicitly.
Hope this helps!

It does help, thanks. I've been using the same sim since my Samsung e315 flip phone.
Maybe it's time for a new one, lol.

Nah, service hasn't been bad, was just curious if it would get better. Never followed up on it.

I tried everything I could think of then broke down and went to the store today. The guy restarted the phone insisting that would fix it. Even when I told him I do it all the time. Thats when he blamed it on the custom rom due to the boot animation I have on it. I reassured him that its still the same rom, so he wanted to wipe it. Told him I tried it and no go. I had already told him I just wanted a new sim and he refused to even look at it. So at this point I asked for the manager. First they I told the manager was I could not get data and voice at the same time and I wanted a new sim. He popped the sim card and said it was only a 3g sim (kinda odd cause its a sim from a wing and could get H.)
Long store short he gave me a new sim and it works fine. So make sure you don't let anyone know you have a rooted phone... the idiots like to think thats the reason for all the problems.

With all due respect I wouldn't even walk into a T-mobile store with a rooted phone.
At the bare minimum I would nandroid back to stock rooted rom before going in.

I never had that problem back in the day with my g1

yeah I know... I kinda was just hopping he would look at the sim. Even before he rebooted and found it was rooted he insisted it was something else. Its all good phone works great now!

[Q] Fringe 4g data drop - wtf?

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!!!

[Q] Connection probs?

I just did the OTA update. Worked fine and sustained root. Brought my phone back to the way I like it and then, it said my phone was not connected. Just on WiFi. the 4G was gone(even though we don't have 4G here(Iowa)). So from like 11:30PM - 12:30AM I was without service. Anyone else too? Want to make sure it isn't a problem with the OS or whatever.
PS: Verizon is all over Des Moines, IA with LTE... AT&T 3G and EDGE in Des Moines... Stupid Stupid Stupid!! (this was a rant)

Hspa + is in design Moines too

same here
It is the same here. Working fine before update. After the recent update, problems with cell signal started all around. The phone works fine if it is static, as it keeps connected to the same cell. But once the movement starts and the phone needs to jump to a different cell, it loses signal.
Doing some research with the "network" app, seems like the phone is no seeing neighbor cells.

No issues after I updated (and sustained root).
And I have 4g just about everywhere here in Atlanta

You're right... I browse and text more than I call but it's still noticeable...
However I have had 1 bar of service for the past couple days, now that I'm home I'll see if it still happens.

No issues here either, and I have been travelling 800 miles by car each week this year for work. I don't ever lose signal...I lose data connectivity sometimes when I go in and out of roaming areas, but that has happened on every Android, CDMA or GSM, that I have ever owned.

I'm on 2.3.5 and sometimes cell signal is dissapear after some period (3-4 hours on connection).
I doubt to update it to 2.3.6 that it will makes my cell signals even worse.
Could someone enlighten me about update?
Thx

Have to turn off mobile data 2-3 times a day

I have had internet connectivity issues that get cleared up immediatley after i disable mobile data and then re-enable.
It happens when i am in a solid 4g area sitting in the same place surfing the web and my data will just die. and it comes back right up after i disable and re-enable my mobile data.
it also happens when im on the bus going back and forth between 3g and 4g.
is this a normal droid charge issue?
seems like it craps out after about 10 min of surfing every time i remember it happening.
i had this happen when i was stock, after i rooted stock, and now on tweek 2.0

Had that issue yesterday on 4G, and it cleared up the same evening. Occasionally will lose data connectivity on 4G, even with it's still showing the connection. It's not very frequent or consistent, and it seems to have gotten better over time. There is definitely some flakiness on the radios on the Charge. A friend was sitting right next to me on his Spectrum yesterday and wasn't having any issues. I think it's likely related to Verizon network, but I think some phones are more sensitive to it than others.

Yeah, happens to me too. I had to disable/re-enable data at least twice today. :/

This happened to me the first couple of days I had the phone. I went to Verizon and they swapped the SIM. Worked fine after then.

hmm.. i did have a few sim issues when i got the phone a week ago, after loading a rom the phone said there was no sim inserted or there was a sim error cant remember which.
maybe swap the sim tomorrow to see if that helps.
sounds like it might be a charge radio issue... i am getting what ever killer phone comes out in a few months anyway. Galaxy s3? HTC one X ? Galaxy Journal ?
Motorola hd ?

re
So i got a new sim..
Nothing has changed.
I have netflix and live in a great 4g area and still have to toggle off data 2-3 times a morning on my bus trip into seattle.
It seems like the radio has a hard time figuring out wtf to do once it comes in and out of 4g. I can be sitting at in traffic for 5 min with no signal and flipping the data on and then off... BAM 4g is back.
This makes for annoying netflix / IT Crowd, viewing.
I am glad that i got this phone as a temp solution cheap from craigslist. Motorola Droid fighter or Galaxy S3 will be putting this lump of mediocre electronics to rest in the next month or so.

What radio is installed on your phone? To find this out go to settings/about phone. The baseband version would be your radio. If it says i510.06V.FP1, that means you are on the most up to date radio. I had similar issues before I updated to FP1 but since then, the 3 or 4G has been very quick to connect and stays reliable all day.

One of my buds works for Vzw and he told me that the 4g network is great when it works. In some places vzw is activating 4g network before the network is ready to be deployed. They are doing this because competition has more 4g coverage.
One solution is to set your phone to 3g only and accept reliable slow sppeds or deal with crappy 4g. Eventually vzw will get it right. Wjen though, is anybody's guess.

[Q] Serious signal strength issues on Stock TouchWiz

Picked up my SGS3 on Friday after my Bionic finally keeled over in a few fairly critical ways. This was always my planned upgrade, got lucky on a Sam's Club special for 96 cents. Phone is so new it squeaks, as is the SIM. I first noticed that calls were dropping out some in certain spots at my house and near my work. I then realized I had zero 4G signal in the house, and didn't seem to be able to get any in my yard. My Bionic was always able to pull 1-2 bars, with only occasional drops to 3G in a couple of spots in the house. 3G was giving me max bars at all times.
Grabbed a handy app - Advanced Signal Status - that gives me detailed readouts on signal strength. I installed it on my (now inactive) Bionic, and where my GS3 is getting about -95dB for voice and -107dB for EVDO data, my Bionic is getting -90dB voice and -45dB EVDO data. Even my old HTC Droid Incredible 2, with one of the worst antenna designs ever, is sitting about -95 voice and -80 data. I even tried it on my wife's LG Spectrum 2. No valid data reading for 3G/EVDO because she's got a consistent 2-3 bars of 4G everywhere in the house. Same thing with work, everyone with a Samsung product on Verizon (no SGS3s unfortunately, but a couple of Note 2s) are getting a couple of bars of 4G, and my Bionic used to do the same.
I've tried flashing back from MF1 to MB1 firmware/tz/modem AIO packages, swapped from Global to LTE/CDMA, battery reseat, SIM reseat, and I'm contemplating doing a rain dance to see if that will bring the signal up to something decent, because nothing else is working. I called Verizon, got past front-line support, started throwing numbers at Tier 2, and they escalated to the network team to rule out a "network problem in my area". Given that NOBODY ELSE is seeing this craptastic signal, I doubt it's that.
I've done a couple of searches but haven't come up with anything worth mentioning yet, either here or on the net in general. I'm still within my grace period and I may be able to bypass having to go back to the Sam's Club I bought it at if VZ wants me changing the phone out, but I want as much time as I can get to test a second one if I need it, before giving up and going with a Razr HD or something. If anyone can suggest something that I might be missing that I can try, I'd appreciate it.

Take off the back of your S3, take out the battery, and tighten the screw's on the phone. This is usually the case for bad GPS and signal issues.

I am in the same boat. But mine will be 2 bars then it crashes to no service. Can't even send texts! I am lucky to have a call for 1-2 min before it drops. They sent me a new sim and as I suspected it didn't fix anything so now I get to waste more time calling them tomorrow. I will literally have signal, unlock the phone, type a message, hit send then get the "No mobiles signal found". Wtf lol
I tried tightening my screws. They weren't lose and it didn't help. Lol

My first s3 had signal issues like what you are experiencing. I had to go through two weeks of stupid waiting for Verizon to test the local network before they agreed it was a problem with the phone. Sent it back and got my replacement. Replacement worked fine.
