What happens if no 3g is available? Does this apply to the uk as well?

at&t
two questions:
1. Will this enable 3g use on at&t's network?
2. Is it possible to revert?

1. No
2. Yes, just tap in the same code and switch it back.

You can switch back by using the same code.
If you do not have 3G while this is set to 3G only you will not have any data service, unless you switch it back.
It will not make 3G work on ATT (different frequency)

for those who weren't paying attention when they did this, the default setting is "WCDMA Preferred".

i dont understand why you wouldn't leave it as that????

Well, because if you are out of 3G coverage area, you don't have and data coverage any more, no web, no email, no syncs, no map. nothing.

Wow, Thank you for the trick, after I did the trick, I tested my 3G speed 4 times to make sure it, My 3G speed is increased greatly. Before this trick I only got about 480 kbit/s, now I tested 4 time I get average 780 kbit/s. That is cool!
Thank again.

TMobile Edge to H signal???

I live on the borderline Edge and G3/H signal towers. When it switches to Edge, the G2 is EXTREMELY slow on the data.
Is there anyway to force the G2 to maintain the G3/H signal and cut out the edge? I live in Rancho Cucamonga, CA and seems that its always on edge instead of the faster speeds. Please help!

Try going to settings> mobile networks
Then make sure that "use only 2g networks" is off
Then go to access points name and select "tmobile data" if that doesn't work go to a tmo store and complain

Dont need to reboot. Also note that if your not in a 3g/4g area it will give you no signal

It's *#*#4636#*#*
GSM/Auto (PRL) seems to hold onto UMTS/HSPA longer than WCDMA (Preferred).

http://forum.xda-developers.com/showpost.php?p=6591742&postcount=2

tried to force the setting but it will go back to the wcdma preferred setting afterwards...anyone see the same?
is the Gsm/AUTO only better?

Not sure. Sometimes it seems like if I back out instead of hitting home it defaults back.

According to "T-Mobile" they said there upgrading their towers for the HSPA+ network thats why calls and text messages are not going thru sometimes........Lol!!

I just pressed back after changing the setting on mine and it's sticking.
I set it to GSM Auto (PRL) and it does seem to make a big difference in battery life (3G coverage is kinda funny in my area).

You have the # and * transposed.
Try *#*#4636#*#*. You shouldn't have to try dialing, it should immediately jump into testing mode

[Q] HSPA+ or 3g or 2g setting

hi i came from a mytouch slide and i was able to set the network to 2g or 3g or even both at the same time. is there a way to turn off 2g on the g2? or even turn off HSPA+ and only use 3g? i've been looking around and can't seem to find anything on this. i'm not rooted but if i need to be that will be fine.

Have you tried dialing#*#*4636*#*#?
Sent from my CyanogenMod powered G2.

Yes. The easiest way is to go to the phone dialer and type in:
*#*#4636#*#*
This will take you to a menu.
1) Choose "Phone Information"
2) Scroll down and there is a drop down menu.
Default is "WCDMA Preferred" --- Which is 3G/2G with 3G preferred.
You may choose WCDMA only for 3G only or Edge for 2G only.

I don't think you can turn off hspa+ but you can just go to settings ---- wireless--- mobile networks--- and just check 2g only for edge and leave it off for 3g/H+

... hspa+ ***IS*** 3g.... so you apparently want to choose between 3g and 3g? Can't happen.

it can be done but requires a reboot. You will need to add/change the setting "hsxpa=0" in the build.prop. this will remove the "4g" also you may need to change lines that referance the ril libraries to remove the reference to "rilswitch". But that might just be with cm6...

4G not connecting

Hi,
i experience a problem on note 4 where despite LTE/WCDMA/GSM (auto connect) is selected, the phone reports only H+ instead of 4G. is there any suggestion on how to make it connect to 4G?
some hints:
- the phone is running stock rom , not rooted.
- no issue with 4G coverage. other phones in the same area are registered on 4G network just fine.
- same carrier between phones.
waiting for your input and thank you for your time.
Thnx

Your SIM card is already a 4G SIM Card?
My phone could get a 4G in the 4G area, but I don't have the option LTE/WCDMA/GSM (Auto Connect).
But in a non 4G area.. it changes to H+

Try dialling *#*#4636#*#* and select the first entry (Telephone information). You can set your preferred network type there. On my phone there are a lot of options to choose from, including LTE only, WCDMA only, etc.
