Whenever my friend is connected to net on a laptop using a WM6.1 machine with Internet sharing on a USB link and GPRS/Edge Internet connection she gets a Voicemail reply to any callers? Is this a problem with the phone or GSM provider.
It´s a network thing. Some providers set higher priorities to voice calls, so an active GPRS data connection is interrupted, others (like the one I have) unfortunately send incoming calls to voicemail and hold the data connection active.
Thought as much, thanks for the heads up.
Hello,
I have my phone for few weeks already and today i noticed one major issue. I will try to explain everything as clear as it is possible.
While i am on 3g network, there are no problems at all. I can make a call, i can receive a call, i can receive SMS etc... Everything works as it should be.
When i switch to 2g that's when the problem comes in. In the first 15 seconds after switching to 2g, i can operate my phone as in 3g - i can send and receive calls, i can send and receive SMS'es. After 15 seconds there is no ability to receive any call. The caller alway hears the same song: "the phone you are trying to reach is either turned off or out of radio coverage...". Also no SMS'es can reach my phone. Despite of this, i can send a call any time i want...
There's one thing i've noticed. When i turn my mobile data on - everything works just fine (you should be familiar with turning off mobile data function), but this is unacceptable to my mind. It seems that when i want to receive a call, i should be on 3g (doesn't matter if mobile data is turned off or on), or on 2g but with mobile data turned on...
I did one test - changed the APN's entry to a messy one, and left the mobile data on. Still wasn't able to receive any calls. Thats leads to a statement: while on to 2g, i have to be connected to the internet to receive a call, while on 3g, i can disconnect form the internet and still be able to receive all calls.
Additional info: HTC Desire - unbranded, non-rooted, stock ROM.
Can anyone help me to solve this issue?
It seems this problem only appears at home. At work (15 miles away form home) i can be on 2G and still able to receive incoming calls... Any ideas?
Sometimes at home can't get damn 3g signal. So I got wifi how do I send messages using wifi???? ****'s very annoying.
Text is a voice service it doesn't use data at all. If you can't text making/receiving phone calls must be hard at your home as well. Over wifi Google voice or a similar app from the play store would be your best bet
Yes, you can. The best way to do it would be Google Voice, but there are other apps out there capable of it. The way the carriers handle it (in this case Sprint) is over the network... GSM or CDMA. 3g is always an extension of the mobile voice network... this is why you typically cannot make calls and browse the web while on 3g (although Sprint has found a way to defeat this with the Viper and the Evo LTE, though a second chipset). 4g runs on a different band than 3g does, which means it doesn't affect your calling / text capabilities.
I know that is more info than you asked for. The long and short of it is that you need an app designed to run on Wifi, rather than mobile data, but it is possible.
+1 for google voice. I even use it to text from my Nook which doesn't even have 3g.

G voice.. or complain to sprint and get a airave and hook it up to your wireless router and have signal in your house .. or get roam control (assuming your rooted) and roam when your home and use your wifi for your data needs and sure youll be fine since wont need to worry about sprint and data roaming

I have to use roam control and wifi at my house. I spend most my time in my game room in the basement and.my sprint service sucks down there. But I get perfect signal roaming.

Uh, slvrap1 already stated this in so many words above. We're discussing workarounds now. And yes, Google Voice is the easiest way to go if you're using an Android phone.
A lot of the information in this thread is wrong...
SMS is actually a function over 1xRTT (just like voice calls) not EVDO (3g)... This is why you can recieve sms messages while on a phone call but not get other data services at the same time...
You never make a phone call or transmit SMS messages over EVDO, it is a data only connection protocol..
This is why SMS are limited to a certain number of characters, because they are actually a hack of the control channel in 1xRTT communications...
Simplified version:
REAL SMS is a hack of the control channel between cell phone and tower. It has nothing to do with a data connection so it can not be transmitted via EVDO, WIFI or any other data connection...
Note: When I state REAL SMS that is because services like google voice and others are all VOIP connections that use data connections to transmit messages and phone conversations... There is character limit in VOIP texting but they impose it because you can send it to a REAL SMS and that has character limitations built in..

Correct. Texting has nothing to do with 3g. You can find an app that can use 3g or wifi to text o stead of the network. This is what my friend uses on AT&T so they don't have to pay for text messages. They use the network.

That actually just sends the message via the data connection to a server, which then relays that into the carrier's system and is then transmitted to the recievers phone via the 1xRTT control channel... They aren't actually texting a phone, they are sending an instant message to a server that then knows how to convert and relay that into a text message.
Note: I use 1xRTT because we are on a CDMA2000 system... for AT&T, T-Mobile and other GSM it works on their *2g* voice connection... I forgot what it is called at this moment...
Use roam control at home, Verizon probably covers you better. 1x roaming is free other than your minutes

Well let me say this. I was at a music festival in March. Had some signal bars but could not make calls or texts. Incoming or outgoing.
When I was in a certain stage I tried again (text) they all failed. I tried to turn on wifi and found an open network! Tried to text. Success!
So in my experience I say yes! Anywhere else I could not text. So when I needed to text I would return to that stage and connect to wifi.

More likely when you moved you connected to a less loaded tower, being connected to wifi was just a coincidence.

Well if you are connected to WiMAX or Wifi.. yes you can make a phone call and surf the web at the same time.. If you are on EVDO, the only way that is possible is if you have 2 cell phones... One to surf the web and one to make calls

Your experience is only coincidental... It is physically impossible because the SMS system is built on the 1xRTT control channel... It has nothing to do with the data connection in any way shape or form... It is a hack on the tower identification and protocol transmission channel.
It is like if you take out a frozen piece of meat, turn on the microwave and leave the piece of meat outside the microwave (never put it in the microwave) and claim the microwave is defrosting the meat...

Are you reading? He obviously cant text at home.. he did say 3g but probably doesnt know what HES talking about.. i think its safe to say hes getting NO signal since he is unable to send text messages.. thus want other options to send text messages which people are giving.. he doesnt care how the network works and how it uses 1xrtt and not his 3g radio.. he just wants optiong to improve him sending messages at home which no matter how we put it, theres only a few options we've already determine which is 1: google voice or other voip messaging app. 2: using roam control to make sure he has signal to send it regularly while roaming. 3: can get airrave and hook up to his wifi at home to bost his signal inside of the house. 4: leave his house and go walk around til he can send one lol 5: someone said theres apps which allow you to send it over data which then gets converted in the tower and sent as normal.. good luck OP! Probably already found a way just wanted to try and get the thread back on topic for ya lol

Google voice will only allow you to text over your google voice phone number... If you use google voice to manage your SMS and text using your phone number, it will still send it via SMS (1xRTT control channel) and will fail There is no alternative when you want to use your actual phone number except for utilizing the sprint web tool.. log into your account and send a text message from the web tool.\
Note: I am one of those people that will correct wrong information if i see it, even if it doesn't 100% pertain to the original post. IMHO it is the only way to ensure people don't start repeating the wrong information and exponentially make it harder to teach people the correct answer.
I am not able to send/receive MMS while on WiFi Calling. It only works when connected to T-Mobile Mobile Data (Edge/3G/4G). Are you guys able to send/receive MMS on WiFi Calling? Is there some network/messaging settings I need to change on my phone?
Anybody else have any issues with MMS while on WiFi calling? Or does it only work when connected Edge/4g?
Only works connected to network, because how is set up, I believe you can get it to work with other apps tho, I'm not sure might want to try, when you have wifi calling on it turns Off the radio, btw this is for tmobile

I can send and receive SMS, but not MMS. Text messages work, but if someone tries to send me a picture, I get a Download button that does nothing.
To get the picture I have to turn off WiFi and download it via HSPA+ or Edge.
Yeah that's how it works

Hey guys, I was using my phone fine all day, but then a text didn't send. Tried again and nope. I tried calling someone but I never heard a ring. I tried putting in airplane mode and turning it off and on. I even installed a new ROM (clean flash) and still the same problems. I can receive SMS fine but most of my SMS won't send. And my data works just fine .any suggestions? I live right in front of a tower and get full bars BTW.

Perhaps your roam settings got jacked. Make sure it is set to "Automatic" and not "Sprint Only"
It could be Sprint, they may be doing updates if your are is set for Vision Network upgrades.
