this phone probaly has what it takes to handle such function but i know was of now metro does not provide us with such service ,i might be wrong dont quote me but i dont know for now if cdma phones can do talk and data at same time i mean the reason i say that is beacause at&t have always rubbed that against verizon's face even though verizon is has the fastest network and the most coverage but they have yet to have establish that service so im assuming those cell phone companies that deal with gsm phones or aka sim card phone have the ability to do such things. but i also just read in the forum about 5g and how researchers have been able to broad cast high speed broadband with phone signal on normal spectrum so who knows metro might take a poke at it as well.

Do you mean like be on the phone with someone and at the same time browse the internet? if so then yes because i've done it. In fact i was just on the phone with my cousin the other day when he asked me something i didn't know much to and so i put him on speaker and googled.

Right now with LTE, it's only data. There is no voice on LTE, on the carrier's spectrum. Yes, you can use Google Voice on LTE, accessing the internet, but that's a workaround.

With LTE phones -- ALL LTE phones, even Verizon -- for voice you use the carrier's other technology. In the case of Verizon and MetroPCS, that would be CDMA. So, you are talking on CDMA and browsing/downloading email/facebooking on LTE. Thus, you are using two radios at the same time, and battery usage sucks.

Or when you were on the phone with your cousin, might have even been on wi-fi rather than LTE.

It's just with CDMA-only phones like the Optimus, you can't talk and browse the same time while using CDMA. If you are on a wi-fi network, with a phone like the Optimus you can talk on CDMA and be on the internet at the same time.

But with VoLTE, you will be able to talk and browse on LTE at the same time -- thus using only one radio and your battery life will be so much better.

I stand corrected then because you're right, i was connected via wi-fi.

If you are asking how do GSM (3G) phones do it and CDMA (3G) does not, it's because GSM is a different technology than CDMA. CDMA gives you better voice quality (that's why Verizon sounds so much better than AT&T in head-to-head tests),

Due to CDMA's military roots, it was designed to withstand interference
