[Q] Can you start wifi while in a call? I can't...

Am I the only one who needs to have wifi connected before a phone call in order to use the wifi while talking? Is this the norm?

I turn wifi on all the time during phone calls.

So while you are in a conversation and wifi is turned off. You can turn it on and it starts? For some reason it won't for me.

I've noticed the same issue wifi nor tether works during a call, I think this is normal but I may be wrong as I am fully rooted NAND unlocked.

Wifi only & Disable GSM?

Guys I am going away with work for four months somewhere which will cost me fortune to use my phone. That said I want to take it with me use it as a tablet of sorts as I have access to wifi.
I know I can turn off mobile data, but can I disable the GSM modem too. Basically I want airplane mode but with wifi enabled. That way there is no chance of any costs been incurred.
Thanks

Don't know if it works for you, but I just tested like this:
- Go to Settings/Wireless & Networks/Mobile networks/Network operators
- Just select an operator different from the sim card you have
Wifi should still work.

I use a free app from market called airplane settings that allows you to select which radios to keep active when turning on airplane mode. It works with latest Runny v4 so should work for you.

Turn on Airplane mode, then turn on WiFi. Wifi should be turned on and gsm is still off
I do what i want, because I can.

Never thought to try that as figured airplane mode would have killed the wifi entirely. It seems to work so thanks!

What about just removing the SIM Card?

Would perfer to keep it in, there is the availability to use my phone where I am going, just is very expensive, if need be I can then just turn it back on and make a quick call/send a text. Just dont want it standby all the time with the ability to cost me a fortune to recieve calls!

I must than be doing something wrong here. The moment I go into Airplane mode, my WiFi gets turned off and won't turn on untill I disable airplane mode. So what's the catch here.

What you want is very easy just go to setting> wireless. And then take the mark away by data connection.
And if you want airplane mode with wifi enabled that's easy to: First put airplane mode on and after that switch wifi back on.

Yep, switch to Airplane-Mode and turn on Wifi.
I did that some weeks ago when I went to Israel and gonna do it again when i'll be in England this weekend.

Remember to turn off your voicemail (you may have to talk to your provider), or youll be paying international rates for any calls you miss.

Yes indeed or else you will be charged if people speak into your voicemail. Well I already disabled it for a long time, I don't see the use off voicemail, people can better send an e-mail or text message.

Are you guys running stock ROM's or costom ones.
I tested it yesterday several times, but when I go into Airplane mode, I can enable WiFi but it does not connect to known AccessPoints.
Also does not give me a list of found AccessPoints.
[edit]
Just because I wouldn't instantly disbelieve you guyes I tried it one more time, and a miracle happend.
It connected to the WiFi access point on Airplane mode.
So what you were saying is the correct way

Had forgotten about the voicemail part, thankfully I can phone it myself before i leave and disable it from the options menu so thats easy enough. Will just place a new message on it from me saying I am away and to contact me by email.
Thanks for the help though, I knew you guys would have a solution to this!

*#*#4636#*#*
1. Put *#*#4636#*#* into the Dialer (or use any application available on the Market like 4636 — takes you to the same service screen)
2. Choose Phone Information
3. Press Turn off radio

Thanks

Turning ON Airplane and Switching ON WiFi works like a charm.
Thanks..

I know its old thread but good for googlers. Airplane mode will not disable internal modem as you can still see its active under battery details straight red bar = weak or searching for signal. Its draining battery and its still able send/receive data. I read about flashing a script to completely turn it off and cut its power but it shows pie security error in terminal -.- I deleted dialer&related stuff from phone as its only used with VoiP so I can't access service menu. Do you still get red line in battery details and does the modem stays off after a reboot? Some devices you can actually physically remove the modem.

[Q] E4GT & International Travel

Is there a way to keep the E4GT on Internationally without worrying about coming home to a big Sprint bill?
I'm going out of the country for the first time and want to keep my phone on for the alarm clock function but want to prevent any data from being used (e.g.: apps using the 4G/3G signal in the background) that I could be billed for. Are there any settings I should be aware of besides turning off options related to roaming (settings>wireless & network>roaming)?
Also, to prevent apps from running in the background, how do you stop them from running? Do you force close them manually in Applications (not sure if they'll boot themselves back up after a certain time automatically)? Or could I just turn on Airplane mode and stop all Internet functions?
Any advice from seasoned travelers would be appreciated, thanks!

Where are u going?

You can just leave it on. The odds that you are going to have any cdma service to roam on internationally, to even receive data charges are slim to none. I was just in Chile and had absolutely no service at all. None in Panama either.

No. I was on a business trip. But in Bermuda you might have a chance of a signal. Your best bet is to call Sprint and see. Or airplane mode it. Just remember to set the time to compensate for the time difference if any, I'd you're going to use your alarm clock.

You can do airplane mode or just go in to settings and turn off just the 3G data and set your voice roaming to "Sprint Only". 4G would obviously not work outside the US so no worries there. The above will still let you access wifi where airplane mode will turn all radios off.

I figured as much, just checked a map and noticed how close it is from the States. As prior answers go, I guess the safest choice is to Airplane mode it.

Happens to me too I believe my frined.
It only happens with mobile data though.
If you are on Wifi, the wifi should NOT disconnect right?

ya if it is on wifi then it is ok. not data connection though

I believe that the phone switches to 2g during calls, and not sure whether this is a telco setting that they do not allow calls through 3g, or a software feature of the phone with the reasoning that 2g signals are generally stronger in most parts of the world compared to 3g.

Just fyi i had the same issue on my "old" Desire HD.

It might be carrier specific. I have no trouble getting (and keeping) HSPA data when I'm in a call.

which version do u have Barry? I am using the international version on rogers. Are you using the at&t version?

Then I believe it to be carrier specific then since the software governing these kinda things should be standard across the board

A UK international version on AT&T.

Ok that is so strange. I have the Hong kong version on rogers network. It never happened to me before and I have used a lot of HTC and unlocked phones before.

ok so i dont think its the carrier cuz i reset the phone and it works sometimes now. if i make a call and browse right away then it will work but if i leave it for too long then it wont work.

guys its because the phone calls you make are on a 2g bandwidth unless its a video call, that's why if you have 2g connection or EDGE active it will get disabled as soon as you make a call.
to clarify, force your network settings to wcdma and then connect to 3g, after that make a call and your 3g will not be disconnected

Hi Marktang... I saw your post from Google as I lost data connection during phone call with my Galaxy S2.
May I know is it after configure the Network Mode inside the setting to use WCDMA only, then the problem will be solved?
Thank you...

App idea 2g when screen off

Does any sort of app exist? I'm rooted and for battery saving purposes, would it not be a good idea to switch to 2g automatically when the screen is off for more than a minute? Then when the phone is woken up switch back to 3g?
I'm not talking about turning data off completely as this would stop whatsapp messages coming through.

Not sure if that's what you need though.
It uses mobile data though... For 2g and 3g I'll try to create a new app for that
But for now yeah that's what I have

Would Tasker not be able to do that?
(I've only used it a few times recently but sounds within its capabilities)

It is built using tasker.

I tried to use Tasker for this but not sure how to configure it. Anyone successfully configure please share the steps..

if you turn off the 3g while the screen is off, you wont receive any emails is this correct?

2g... Data is data. Psst, you can watch Youtube without 3g!

It's not that simple and probably not worthwhile. 2G and 3G on standby are pretty close in terms of power usage, the only time you usually find an advantage with 2G is where the 3G signal is weaker, so less power is used keeping in touch with the 2G tower. If you fix the phone to 2G, you also save some power if moving around as the phone is only talking/listening to 2G cells, and less likely to be swapping about. When you have "auto" selected and you are moving around the phone has to monitor both 2G and 3G cells to be ready to make a handover decision, so that is extra power.
If you have the phone constantly dropping 2G to go to 3G when you turn on the screen, then back again, that all takes extra power to negotiate with the cells. Also if you get a phone call and the phone switches to 3G, this will drop all connections when the setting is changed, as you can only have a smooth handover when the phone is in "auto" mode and has already established a handover strategy.
Then you need to factor in data usage. When any applications sync while your phone is in standby (screen off) if on 2G that sync is going to take longer, and the longer it takes the longer your phone has to stay awake to wait for it to happen, and the radio is on longer transmitting, so more power is used than there might have been on 3G.
The net effect of such a setting is likely to use more power overall.
