[Q] Does Mobile Data affect call quality? - T-Mobile Samsung Galaxy S II SGH-T989

I keep mobile data off most of the time.
Just wondering if it makes any difference in call quality.
Also between:
Gprs vs Edge vs 3G vs Hspa+
is there any noticeable call quality difference?
Hercules on TMo.
Thanks.

Nope. Data is data, phone and texts are handled separately.

No it doesn't affect data

That's what I thought, but then, why are calling times rated by 3g vs 2g?
Like 16 hours of talk time on 3G and 30 hours on 2G.
What's that all about?

3g uses more battery than 2g, obviously. You don't need data on at all to make phone calls.

There is a lot of free apps on the Play Store for wifi calling.. But some do need ROOT access for it to work.. [my preference - most of the good ones will need root access ]

Is there any real difference between 2.3.5 and 2.3.6?

I see that some of the roms are made using both but I was curious if theres any real difference between these two other than the search bug was fixed. Are there any other advantages to using one over the other? Thanks in advance

Better battery Life
Plus in my experience using WiFi over T-mobile's data is better for battery life because WiFi is more consistent.
HuGE diff between them. . . Home button lag removed, better scrolling, smoother transitions, better battery life, wifi calling, other bug fixes.

It seems right the battery is better for me.
Calling over WiFi is not important for me since I have unlimited calling.

Don't forget that you can use wifi calling to make calls or send sms/mms when there's weak or no cell phone signal.

[Q] What is Enhanced 3G?

So while I wait for LTE service and a phone that can use it, I keep hearing about Sprint upgrading to "Enhanced 3G.
But what do they mean? Faster download speeds? Voice and data at the same time? Is it simply marketing BS?
I'm not finding an explanation of it anywhere.

I don't think is voice and data at the same time because CORRECT ME if I'm wrong someone BUT I believe that's a cdma issue BUT to answer your question......Enhanced 3G is just that, is better 3G! Improved 3G speeds....NOTHING more, NOTHING less!
I believe its the new HD voice service recently announced.

Not to worry... it is a new compression algorithm to get more data packets into the same bandwidth. It should improve the speed of 3G data networks.
It is about 50/50 improvement vs marketing.
See ya'

No, that's only LTE.
Voice does not transmit over 3g, wimax or LTE HD voice is sent over 1x-Advanced. 3g. WiMax and LTE all are used for data and MMs only, voice and SMS go over the 1x channel, CDMA limits the use of 1x or 3g/wimax to one or the other at a time, once LTE is available when using it you will be able to simultaneously use voice and data, theoretically, since LTE will be using a SIM card for its activation, much the same way VZW LTE works.

Correct.
wait is sprint finally jumping ship to the much better evdo rev b.? or is it still rev a but updated slightly to make it not as slow?
Its rev.a but with better compression and abackhaul that will allow for about 5x the current bandwidth per tower giving off higher aand more consistent speeds

I've only used wimax 2 or 3x, but it would make sense since it is a separate radio and wimax doesn't handle voice. The biggest benefit to LTE is its going out everywhere 3g is now and should have same or similar building penetration. Hell I live in the country 20 miles from town and 40 from a real city and my towers are scheduled for LTE in phase 2 this year which I was surprised but the whole southwest of my state is getting covered in the same rollout something like 200 towers from Sarasota/bradenton to Naples

Being that Boost Mobile runs on the Sprint CDMA network, do any of you think that this new compression will also improve Boost Mobile data speeds or does Boost have their own network filters to regulate the speeds? Add Virgin mobile to that question too. Just curious.

Side Note at att store yesterday: I was at a ATT store checking out the Salaxy Note and a customer came in to exchange his old blackberry because ATT sent him a letter that ATT is getting rid of their 1x or 2x services. Found that interesting kind of how Sprint is going to upgrade all their iDen NextTel network to LTE.

You said you have no LTE in your area. Why are you trying to turn something off that you can't even connect to? You are not getting LTE drain since you don't have the service.

You should give "Juice defender" a try. It's free on google play. It's default mode is to turn off all cell data (and that probably mean SMS too) while the screen is off and then it turns on to sync emails/other data stuff every 15 minutes while the screen is off. When you turn the screen on the data is back in seconds. My battery life is amazing so I don't use this app but it's pretty popular so XDA threads probably have a lot about any bugs this app would cause.

I might give it a shot, so if there is no lte in my area, I won't get the battery drain its automatically off?

[Q] Simultaneous Voice and Data GS3 T-Mobile

I have a GS3 with T-Mobile prepaid (60 a month) my Simultaneous Voice and Data is not working? is this a problem with the prepaid service? the Simultaneous Voice and Data will work for a few min's then cut off and i cant get data back until i end the call im on.
I'm running Cm10 Nightlights
I was on Simple mobile and had the same problem.
is this a phone problem, service problem, ROM problem? i thought T-Mobile supported Simultaneous Voice and Data?
Works great for me but makes sure you have 3g or better.

Voice calls while on LTE?

When you make or get a voice call on LTE, does your phone disconnect from LTE and switch to 3g/H? Just wondering if this is normal?

Yes perfectly normal.
I believe its due to either LTE being Data only or LTE not being able to do Data and voice at the same time. I forget which one it is.
I think it's only data for now

It's actually because lte is being used as HD voice. I'm trying to disable HD voice to see if it changes the behavior.

That doesn't make sense though. If LTE is data only, then it would use LTE for data, and use 4G or anything else for voice, allowing you to have both voice and data.. Unless the radio can only support one frequency at a time then it would force it to use 4G or the next available frequency.
http://m.computerworld.com/s/articl...telephony_apps?mm_ref=https://www.google.com/
VoLTE will enable that... Right now the phones have to have two radios enabled at the same time... One for data and one got voice.
