It does not. Its only over lte.

 

I can check my Gmail (data?) while on the phone (voice?) simultaneously...

Is that what you're asking?

 

If you have a DC why not call your voicemail and then surf the internet and see if it works.

 

My understanding is you can do data and voice simultaneously with Droid Charge as long as you're in a 4G (LTE) area but not if its transmitting over 3G.

 

That's my understanding. The limitation with 3G voice and data is because of the CDMA network as opposed to the GSM 3G network which does allow simultaneous voice and data.
I am skeptical of the TB actually being able to do both on 3G. Im not saying its not truth, but no Verizon phones before have done this.

 

The Thunderbolt can do it over 3g. I have owned both phones and tested it out. The Charge can only do it over lte.

 

Yup it does it over 3G and LTE.

 

With the new 4g LTE they are also installing a NEW 3G network. the Tbolt can do voice and data over 3G (LTE off). Not sure about the charge... sorry.

and the newer 3G does not work with our older 3g phones.......

 

Hi,

I had the thunderbolt in a 3G only market, and it definitely did simultaneous voice and data. I exchange for the Charge, believing that it would also work, as it is 4G LTE, but it doesn't seem to work . Anyone figure out how to make it work? I'm sure it must be possible, probably a software hack/update would make it work. Anyone up for the task?

 

I was told but a Verizon Store employee that the TB can do simultaneous over 3G because it has 2 seperate radios in it (one for voice and one for data) and the Charge doesn't

 

This is what I've heard in the past as well - and the TB was the only phone with those two radios to support this.

 

The Charge will never be able to place a call and do data at the same time on 3G, only while LTE is running or wifi is on. Only the Thunderbolt has a 1x advanced radio.
The Revolution has a chip capable to VoLTE (voice over LTE, not yet used), which the tbolt and charge do not have.

 

Does that mean all voice on dc and tbolt are over the 3g radio and data over the other (lte radio)?

 

Voice on all three phones, the Thunderbolt Charge and Revolution do voice over the CDMA 1x network. Data on these phones can either be over the CDMA 1x/EVDO network, or the LTE network.
