Anyone try out wifi calling/messaging yet? I just sent an mms and the "G" appeared even though the cell signal is off and it's supposed to be through wifi. It took longer than when I'm on 3G too...

i think the mms goes through a diff system when get home ill try it
I believe MMS always goes through cellular data.
This is to prevent an exploit of sending free messages over Wi-fi

Something came up for crackberry users that stopped them from using UMA and since WIFI calling hits the same servers as UMA, i.e... they are the same thing, I suspect that your issue might be the same as what they were having. Your ISP's DNS is blocking the service. If you can change your DNS settings to OpenDNS.com and give it another try. This may not fix your issue, but I know it did for a whole lot of crackberry users.

I get the same error message. Just got off the phone with a tmo rep and she said that there's a signal outage(?) around Atlanta and that's why I can't get ANY cellular connection whatsoever. But I remain skeptical, as my friends on TMO are having no problems and the "outage" just so happened to affect me right after the OTA was installed. My fingers are crossed that everything gets fixed though.
Mines works fine, it depends on what kind of network your on. On my campus it would not work, but when I got to my gf apt it worked perfectly. So check the wifi settings that you haveto make sure there isn't a firewall or something else set up.

Mine works on my college campus great. I have terrible coverage here. This may be a stupid question but, it only uses minutes when I'm actually calling someone right? Not however long it is enabled? I'm only asking because I'm tired of getting screwed over in ways that I logically shouldn't be.
Yea it only uses minutes when you are calling. Also I don't know what college you go but I go to umiami, so our networks are really strict with regard to using them for gaming or any kind of tethering. So I'm guessing they haven't allowed us access to do that here. But on any other networks like a home network it works perfect.

I go to Westfield State in MA. I had to get my phone registered on the resnet net work to use the wifi. Can you use wifi at all at school with your phone?

Crap. I just sorted out my issues with things draining the battery and now Wifi calling is running rampant. It stays running in the foreground even when it is turned off and logcat shows that it is constantly active even when the phone is asleep. Is anyone else seeing anything like this?
well i would like to know why its wifi calling if tmobile still use the mins from your plan thats like stealling it helps tmo they use less data but still charge us for it
Yea genius on their part...even still its not like they're not doing anything. It its still being runs through their network just not through their towers.

yea, what he said. Cellular towers are like a gateway to the Tmobile internet. The still pay for all the fiber and backhaul that gets your calls and data where ever it is that you want them to go.
i just updated and i opened up wifi calling and configured it. i dont understand how its wifi calling when it still uses our minutes? whats the point of having it then? what benefit is there to having this app?
Yea we can but we are literally forced to just web browse lol

T-mobile has had the "charging for minutes via wifi" policy now for YEARS going back to the first Blackberrys that supported UMA. Minutes were deducted unless a customer paid for the @home service per month. You can complain all you want, but if you consider the other carriers and their options---T-Mobile does NOT charge for HSPA+ (4G) access while other carriers do, and some charge even if there isn't 4G in that city just based on the phone! Wifi calling can also prevent you from incurring roaming charges by allowing you to make calls from almost anywhere you can get wifi access a feature that other providers just don't have. T-Mobile gives more minutes for less money, offers more data download than other carriers, and offers some truly awesome features that others just can't compare to.
Although WiFi calling uses up our plans minutes, if we have unlimted weekend minutes, use it on the weekends, is it free or does it take away from the anytime minutes?

Notification bar icons (Wi-Fi, network coverage bars, etc.): Turn green when you have an uninhibited connection to Google, white when you don't. Hint: if you're in a hotel or airport using Wi-Fi, the bars won't turn green until you launch the browser and get past the captive portal.
Click to expand...

But why Google do that?
Why it is waiting the browser to launch?
Or is it just the tips to make it turn to green faster?
hospitals, and airports usually have you agree to some terms before you can full access the net with their connection. That's why. I was on a bus last weekend which blocked many websites, including Googles. So I had an internet connection but YouTube, and other websites were block, and my phone couldn't access the Google servers.
That is a neat feature. Often times my school wifi will do this until I login with my password and username
I was driving and had full bars w/ 3G but could not get any data... no email refresh, no maps update, no web... I turned on and off airplane mode to reset the connection and then the bars turned full w/ 3G but Green and emails and data started flowing...
I think when it is greyed out you have no data connection but there is a connection available... you just arent on it...

That is not correct.
When you have any bars, white or green, you have a data connection. When you have green bars, you have a data connection that's working with Google's sync servers.
I can get websites with white bars, but email and google voice don't sync unless they're green.
This is the only phone I have that behaves like this...I do not like it.

Do you make your calls through Google Voice? I wonder if you have to have a data connection to do that. I don't think it works that way, but might be the issue.
Okay guys, I had an opportunity to test the data-works-with-white-bars situation I mentioned earlier today.
I've uploaded an unedited youtube video showing the phone has white bars and I am able to browse to a website still.
Data definitely works for non-Google-SYNCed services on my phone, even Google sites.
My S seems to display grey/white indicators at times and will not return green unless I reboot. Does anyone else have this issue?
It seems to happen on mine once or twice a day.
Thanks!

It might have happened to me once. I think I rebooted like you did, but in hindsight, I think just going to Settings, Wireless, and turning on/off airplane mode would be just as effective and a little quicker.
This is a very annoying new "feature" of Android and the Nexus S.
This is an awesome feature. Showing that you are "connected" to Wifi or a Cell network is of little value unless you know that the connection is able to get to the internet. Saves you if the internet connection goes down or if the connection needs a login to work, etc.

The phone is able to get to the internet with grey bars. Go back a couple of posts and you'll see a link to a video I made showing that grey bars didn't keep me from opening a web page in the browser. The green/gray doesn't tell you that your connection is down, it tells you that you're not logged in with Google services.
I like the green/white in terms of it telling you your status, what I meant was that the logging out of google services is annoying. I've not seen this kind of behavior (having to wait for green bars or reboot the phone to get to Google) on any of my four prior Android phones.
I wonder if this has anything to do with the tzone/web2go blocking going on.

Agreed, for the last two years my G1 would show a connection and I would try and use a wifi signal to no avail. In the end I knew it was because I needed to agree to some terms but couldn't with my phone's browser or all the things I wanted to use were blocked.
It is also good for troubleshooting. Like if there is something wrong with it connecting to GTalk.
It's funny that it has become such a big item of discussion when it should be there to make life better for us.
I think the discussion is because a lot of people who on prior devices never had issues connecting to GTalk or the Market, or Gmail, or [insert Google app here] all of a sudden are finding that they can't get to them until the bars turn green.
I've certainly never noticed issues on my four prior Androids with this. Power up the screen, open a Google service and it's live.
With the Nexus S (or Gingerbread), power up the screen and wait some random amount of time before the bars turn green. No Google services until the bars turn green.
There's also a lot of confusion over what the green means. Many, many posts out there with people saying that they can't get any data services from any source (ie., browse the web) when the bars are grey. My own test (demonstrated in a video on an early post in this thread) shows that I am able to surf the web to a site with grey bars. At least on my phone, grey does not mean connected but no data...it means connected to working data, but not logged in with Google.

Well that still makes sense, because say your network data connection went down in your area for whatever reason. Your icons would turn white cause obviously you can't ping the Google servers, but at the same time its just a larger issue of totally no data in that particular instance.
But white icons does mean no contact to Google servers only, but regular data should still work.
When I'm using wifi at home, every couple of minutes the HSDPA and HSUPA arrows appear between the wifi and signal strength bars. As far as I know they shouldn't appear when wifi is connected. The problem is that when the arrows appear, I loose all data connection until they go away.
Anyone else experiencing this?
Thanks
So basically when you connect to wifi, then you still have the H+ icon at the top of the screen, however, there isn't suppose to be any data arrows there?
I was wondering about this because on the Evo once you connect to wifi, the 3G icon goes disappears.

Right. I see that H+ on mine too, even after connecting to wifi. It shouldn't be there!!! And I think this is one possible reason why I keep losing my wifi on this phone every other minute, and keeps switching to H.

I am also experiencing this. It is frustrating because it is the only issue that I am having with the phone, but I am on wifi for probably 90% of the day. It is annoying when it happens. Usually turning wifi off and then on again fixes it. Still, I should not have to do this.
Yeah the H shouldn't be there either I think, but the problem is when you see the arrows under the H. Like the phone is trying to download data through HSPA while on wifi but fails at both.
BTW, as many have said, the phone is working flawlessly. This is the only issue I'm having. Probably DG can fix this!
Just got off the phone with ATT and they told me that even though you're on wifi, some data is still carried over where it goes towards your data plan...wtf! I definitely don't like this one bit.
I called them because I was connected to wifi but on my att online account, I noticed that my data usage had increased.
I'm about to get off work so I had to rush while I was on the phone with them. When I get home I'm going to give them another call so that I can better understand this crap. I have no clue why our wifi usage should count towards our data plans.

Not to mention, even if I accepted the fact that they were still putting some amount of data over my data plan even while on wifi... why am I losing all network connection to my phone while this data transfer occurs... Something is definitely not right here.
It seems to be a common issue, there are a ton of threads about this on the Motorola support forums for this phone. I'm having the same issue, it's horribly worse if you are on a call. Whenever I am on a call and phone phone is on wifi and I try to do anything web related it take a long time to load any data, most of the time it won't and it will kick off my wifi and go back to 3g data.
I'm giving it a few more days to see if Motorola replies about this issue, otherwise I'm gonna have to take both atrix's back... this is a pretty big deal breaker for me.

I love these posts because it is also my situation. Check your data and make sure it's not being hemorrhaged like mine was (50MB/DAY!!).
Here is how to stop all data: go into wifi settings, then hit that menu button and settings, change it to never sleep. then go into all your programs and hit never update, manual, whatever. PAIN IN THE ASS but hey...thats the Atrix for you. I returned mine.
When I'm on wifi it shows the H but the arrows don't light up, if I lose the wifi connection it won't load webpages or the market so I think its been working for me
Every once in a while I go to use the phone and my WiFi and Phone signal will have exclamation points beside them. I have to disconnect and reconnect on the WiFi to fix the issue. Is anyone else having this issue?
I only see the exclamation point after boot or when I turn on WiFi: the antenna is in the process of connecting to the network / wireless router. Otherwise, I don't see the ! again.
I had it this morning. Turned off Wifi, and the cell exclamation point went away.

Same here. My phone was sitting beside me and had been getting calls and text messages all day long. I picked it up to look for something on Google Play and it would not connect. I was getting it on my cell signal but that was before I turned on Advanced calling. I was out of town for a conference and would see it while I was on the phone and email was trying to sync. Things that make you go hmmmm.
This happened to me tonight for about an hour. I tried everything but eventually it came back on it's own but only on 3g.

The exclamation point means that the WiFi or cellular signal aren't getting connectivity. The reason that turning signals on/off works is because you force them to reconnect.
You're getting these indicators because for some reason, your WiFi and cell signal are dropping out. If you were at a conference for a few days, then it makes sense you would see that on WiFi (since conference centers notoriously have horrible WiFi; especially when you have a few hundred people all trying to use the WiFi at once). If you saw it on your cell signal, then for whatever reason the cell connectivity dropped out for a moment.
This also happens on other phones. Have you ever tried to use internet connectivity on another phone, only to have it not work? You see full signal strength; you see the data indicator look like it's trying to push / receive data; but for whatever reason, you're not getting data for the moment. This isn't new to the Moto X Pure. It happens on other phones as well. The only difference is that the Moto X Pure tells you its happening.
Honestly, I really don't remember it happening on my previous phones. I'm not saying it did not happen but if it did it was not on a regular basis like here. My business is in my home. I have a wireless router downstairs and upstairs. It has already happened twice today.
I regularly get connection timeouts when browsing the play store, surfing the web, and using xda. On both WiFi and cellular data. I'm assuming its a software issue.
I believe that the cell bars with an exclamation point means that you have voice but no data connectivity. That's the way it has tested out for me over the years on various Android phones. So, you can make and receive calls, but not data.
I think, but am not sure, that the exclamation point with the WiFi icon means that the OS connected to the WiFi access point but not the Internet. That would indicate a handshake issue between the phone and the access point/router, maybe resulting in the phone not receiving an IP address or something. Though I've only seen this happen once or twice over many years, disconnecting and reconnecting the WiFi (turning it off then on on the phone) usually clears the problem.
Just sent mine back as my signal issues really hindered use of phone. Was hoping for ROM before return deadline to see if it would fix it. But that has been slower than I thought. Tried everything in the book to fix this issue. Doesn't matter if I'm in excellent coverage or not. Screen off phone goes 1x then screen on stays until I play around with settings or hidden menu. This is on Verizon. Tried new sims. Wonder if Verizon is doing something to limit these unlocked phones.

That was a given. New nano sim not trimmed down micro. At first I had trimmed my g2 micro sim which I thought was reason for issues at first. I have a friend at local Verizon store who is more knowledgeable than usual CS agents. Still couldn't get anything to stick. Hidden menu setting for network always switches back to lte ,gsm CDMA auto prl. Phone was purchased through amazon. Hope its just hardware related. Gonna go to best buy and pick one up there. Easier to deal with them.

Liked the phone so much. I decided to reorder. Will have today. Here's to hoping it fixes my issue. Lots of signal issues with the custom ROMs right now. Especially Verizon users. Hope it gets ironed out soon. This really makes me think Verizon is doing something even though its not a carrier phone.
It's not necessarily a phone issue. My wife's Moto X 2013 and my Moto X 2015 had this come up on both phones at the same time, exclamation mark by both wifi and lte signal icons. Rebooting phone didn't help. Calling still worked, data did not. I went in and rebooted my router, and the exclamation marks went away on both phones.
I gotta try that.My fiance's X 2013 always gets it in the apartment.Maybe I should try to get her a new sim as well?

I had this happen to me today. I had installed an app that was burning through my cell data, used 90% and I have two weeks left on my billing cycle. I turned of cell data because even with just routine phone useage I did not see the 10% lasting. However after doing this I could not connect to wifi. I have full strength signal and it says it is connected but there is an exclamation mark by the wifi meter and nothing will connect to the internet. I turned cell data back on, and it connects, but wifi will not. I found that by running my vpn it connects and now I get data via wifi through the vpn. If I shut the vpn off, no more wifi data. WTF??? I've researched and this seems to be a lollipop issue on several different phones. I've tried every solution I could, (except for those that require root). Has no one found a solution for this? Motorola?

i have sprint, so yes im without data sometimes and the exclamation point comes up when there is no data on the bars
So when I first got my V20 (VS996), when wifi was connected the mobile data went inactive- at least I'm presuming so, the '4G' was grayed out, not crossed out, and when there's simply no 4G signal it entirely disappears (or drops to 3G etc). But now it ALMOST never does this anymore... every once in a while it will, but there's nothing specific about times it does.
I'm pretty sure that's what it's supposed to be doing, as there's even an option 'Cellular data always active - Always keep mobile data active, even when Wi-Fi is active [...]' (not enabled). I've searched high and low for a setting that could be causing it not to work right, and information about this, but have come up dry. Is anyone familiar with this? Really didn't want to have to reset and track it that way.
Thanks.
Bad WiFi signal bro. Disable your gsm data and see if you can still watch YouTube.

keep mobile data always on
as well as agressive wifi to cellular handoff
as well as under advanced for wifi, you can tell it to switch more agressively off wifi under poor conditions etc

Bad WiFi doesn't seem to be the issue. It's showing max strength and is 2 feet away from the wireless router under my desk, and the issue still persists. (yes, youtube plays fine in HD)

I'm trying to get it to turn mobile data off, not hand off to it even easier. Are you saying that these options will make it disable mobile data when wifi is good, when it's not even doing that without them? Tried that just in case, it's still not deactivating mobile data (still at my desk, wifi router for 100mbps symmetric fiber showing full strength 2' away, so unlikely bad signal)
Edit: I may have found the issue. It appears one of the Verizon apps was forcing the cell connection to stay alive. I tried killing a bunch of the ones I wasn't using after recalling how their voicemail app only runs over cellular, and now mobile data is deactivated. I'll need more trial and error to confirm which one was doing it.. I killed 4 of them.. and it stayed off after re-launch so was clearly some kind of bug. Although it's odd as it did persist through reboots.
Edit: Confirmed; it's the 'Caller Name ID' app. Ending that single process restores the normal mobile data deactivation when wi-fi is good.
So another cause of this problem has popped up. After a reboot, 4G was becoming active after 15-30 minutes despite not touching the phone at all since the reboot, and there were no apps that could be killed to get it to switch off this time. But after a lot of trial and error, the cause was finally isolated: The My Verizon data meter widget. Once it refreshes, it forces cellular data to stay on, even when Wi-Fi is connected and strong. Once the widget was removed from the home screen, 4G never came back on while using WiFi.
Is there any way to disallow an app from using 4G but still allow it to use WiFi? I really would like a better solution than just not being able to use the widget. It would be fine if it just connected, got its update, then disconnected... but no, it's on permanently after a refresh.
