Help 3G Capable?

[XxHaimBondxX]

I wonder if this phone has 3G capability. I noticed that in the event I have poor signal, 4G drops down to 2G and then back to 4G. Gsmarena says it has all three. Did anyone notice 3G on their t-mobile F3?

You have to select in the preferred phone menu . you have just 4g I think its number 2 for the 3g
Go to mobile data and preferred network .

 

[XxHaimBondxX]

You mean enabling it through the secret menu? I've dialed 3845#*659# and got in, but don't see an option you're referring to.

 

[BRAINZ2013]

No this is on the phone settings without putting in any numbers to the pad . just enter the menu>settings>mobile data

 

[XxHaimBondxX]

This just brings me to the data usage/limit screen and the list of apps that use data. There is no option to choose the data speed.

 

[BRAINZ2013]

Where is the box to activate the data for your device

 

[XxHaimBondxX]

Here are screenshots of my screens. Settings, followed by the Mobile Data. There aren't any additional options.

Try
System settings --> More --> Mobile Settings

One of the options allows you to select network

 

[BRAINZ2013]

Try the app in the play store called quick setting this is a toggle that will allow you to disable and enable the 2g,3g and 4g .
Quick setting can be used with any ROM and os

 

[XxHaimBondxX]

It disables WiFi and turns on data, nothing special about the 3G. It seems Tmobile simply doesn't support it for this phone.

 

[BRAINZ2013]

I Dont know which one u are using try this

[XxHaimBondxX]

That's the one.

I Dont know why any cut was removed but if u can find that's the best tool to have and keep a copy in a safe spot .

 

[XxHaimBondxX]

Looks like just a shortcut to the Mobile Networks settings, doesn't really do anything.

 

[BRAINZ2013]

Did it take you to the 2g EV if not that say that u maybe rooted running a mod or custom ROM .

 

[XxHaimBondxX]

I'm able to pick 2G, but not EV. The phone is rooted, but has stock Tmobile ROM.

 

[BRAINZ2013]

The EV is greyed out

 

[XxHaimBondxX]

No, I mean there is no EV option at all. Same thing happening on my wive's identical F3. There is no 3G option at all. It simply jumps from 4G to 2G.

 

[BRAINZ2013]

Is your other device rooted

 

[XxHaimBondxX]

It is, should I try unrooting it?

 

[BRAINZ2013]

So both devices are rooted .

 

[BRAINZ2013]

So both devices are rooted .

If both are rooted u may have either a update or maybe try unrooting and see if u can enable the EV aka 3g then if it stay try to reroot but make sure its no update if it is update before rooting and make a BACKUP before you root .

Okay... It looks like there is some confusion in this thread. I will do my best to clear it up and answer the question.

It looks like the OP has a T-mobile version of the F3. Keep in mind that the T-mobile version is a GSM version of the F3. There is no EV (EV-DO) mode within the chipset. If there is it is not enabled because EV is CDMA technology, which T-mobile does not use.

Now that we have that settled, we also have to understand another thing when it comes to T-mobile phones, which now carries over to MetroPCS and is also duplicated with at&t phones. The phone's notification bar lists the data generation (2G, 3G, 4G, 4G LTE, etc.) next to the status bars. This is a representation of the data speeds the phone has access to (and not the actual broadcast generation, just to keep in mind).

Now T-mobile has decided to change the landscape of the generation types based on the speed of the downlink rather than the actual generation of the technology used. They decided that if the speed of the downlink is high enough it can be considered to be equal to the latest generation, which is currently 4G LTE. So T-mobile lists "4G" while the phone is connected to any WCDMA connection, which upgrades to HSPA or HSPA+ on demand to achieve fast downlinks.

WCDMA is theoretically a 3G technology but because speeds can match those of 4G they opted to just advertise these speeds as 4G.

So while on T-mobile if you see the status bar listing simply "4G" then the phone is actually on a fast 3G connection. "4G" is actually 3G and is not 4G LTE.

So your phone is indeed 3G capable. It just doesn't list it as 3G.

Also, when it comes to newer CDMA Android phones on Sprint and Virgin Mobile (and maybe Verizon), 3G is listed whenever the phone is connected to EVDO or not. So even when the phone is only connected to 1x it will still list the phone being connected to 3G. Just a heads up.
