[Q] Force 3G connection - Xperia Play Q&A, Help & Troubleshooting

I have a AT&T Play 4G. I was wondering if it would be possible to force a 3g connection on the phone? My Play is rooted and has the bootloader unlocked. I am currently running DarkForest's 3.1 rom. I know you can force 2g. To me my phone switches 4g to 2g alot and thought maybe 3g would be a better way to go.
Thanks in advance Andy.

You force 2g by selecting ' GSM only' and 3g by selecting 'WCDMA only' afaik on a stock rom. No idea about darkforest.

I know how to force WCDMA. But it has H in the signal. I was try to get just 3g.

WCDMA refers to 3g. The H symbol stands for High-Speed Downlink Packet Access (HSDPA). Both are indicative of 3g itself.

Froyo - no HSDPA

I have an HTC Desire.
When I install any Froyo-ROM (I am currently running Modaco r20, based on frf85b) i lose my HSDPA, and I can only run 3g.
Can anyone help me activate HSDPA in Froyo?
I believe that FroYo does not show the H symbol, even though you may have H speeds. To check, go into your settings and Status. Look under Mobile Network Type.

[Q] No 3g Download, only HSDPA or EDGE

Various apps (Facebook, Market, Head to Head & Internet Browser) will only download data when there is a connection to the HSDPA signal.
The 3G signal has shown as 3 or 4 bars but will consistently not download any data. Once the HSDPA signal is found, then the download starts. This can be frustrating as there isnt always a HSDPA signal.
i tried to insert another network provider sim card and it showed 3G and when i tried to launch for example browser it instantly changed to HSDPA icon and loaded pages so i didnt check anything... (i couldnt recreate a situation when only 3g was available, no HSDPA)
I currently am on DHD by baadnewz 1.7b but this also happend on Stock Desire Froyo.
any advices ?

It's difficult to comment. If you're rooted, try another custom rom with an updated radio.
i have the newest radio

If the "3G" signe appears in your phone, this means that it's trying to connect to your carrier's network. Once you're identified your can start to use data connection, then you get "H" "E" or another depending on the technology used by your carrier.
H goes for HSDPA, E Edge and so on...
So the lagg time is when your carrier tries to search whether you've got acces to a data plan or not.

Can you change how the phone switches from 2G/3G

I have problems getting a 3G reception at work. My desire displays the H symbol but just doesn't connect to internet at times. If I manually switch to 2G I can connect. It's really slow but better than nothing! I can leave it on 2g all day but as the H signal works intermittently I like to try the 3g signal first before switching back to 2g.
What I would like to know is if there is there a way to change the minimum H signal the phone has to have before it goes down to E. My phone seems to prefer H even if the signal is too low to connect.
Can this be changed?
Yes.
Go to to the secret menu *#*#4636#*#* and select phone information.
Scroll down to the bottom and change
set preferred network type to GSM only.
I think this is a good idea to put through for the already excellent "Toggle2G" app. Thanks for bringing it up

Thanks, didnt know about the secret menu!
Going by the word preferred it sounds like it is what I am looking for but 'GSM only' makes me think it wont switch to 3G.
Does this mean it disables 3G completely? Couldnt I do that just by going into settings and selecting use 2g networks only?
Edit
Just searched GSM only and found this thread http://forum.xda-developers.com/showthread.php?t=688492. A good explanation of each setting, think GSM auto (PRL) is what I am looking for as GSM only is just 2G but I can usually get a 3G signal so I'll give this a try.

[Q] 3g vs. H designator

Im on tmobile usa and the indicator regularly changes back and forth between 3g and H although im in a strong area for hspa+. Anyone having similar issues? Anyway to 'force' H signal?
i agree
i am seeing the same issue
It's not an issue. This is the way it works. When idle the phone is connected to UMTS and displayed as 3G. When it is pulling or pushing data it switches to HSPA ("4G") its displayed as H.
Most carrier builds hide this change and display the icon as "4G" all of the time.
Nothing to be concerned about.
this is normal. any carrier. saves power. only switches to H when you are actively sending/recieving data.
If the 3G to H transition bugs you, I believe the XXKK6 radio maintains the static H when data is not currently in use.

I am on XXKK6 and i assure you that it does not maintain a static H.

This is not the case.
If H stands for 4G, then why does my GSM Nexus display it all the time?? Basicly, it shows up H most of the time.
If it is using data, then the 3G sympol comes on... Is this perhaps a bug? Using 4.0.2 stock, the radio is XXKK6...

H isn't 4G. this it what mobile connections are (in a nutshell)
GPRS (G)
EDGE (E)
3G (3G)
HSDPA (H) (you can call it 3G+ also)
4G (4G)
3G is normally active in a good reception area, but when you are using your internet it uses HSDPA because it is quicker, but also uses more battery. When your are not using internet (say in idle), the phone uses 3G to save battery.

HSPA+ on the A70?

Is there a way to activate HSPA+ on the A70?
If I have two bars on LTE, then three or more bars on 3g will actually give me more speed. The practical difference is that videos on app such as Instagram, load up really slow, or, if on 3g, load fast and is seamless.
But there's also such a thing as 3G with HSPA+, which is supposed to be faster than regular 3g.
Is there a way to activate this on the Samsung?
Thanks.
Open Settings, go to Connections>Mobile Networks. Tap Network Mode. Select 3G/2G instead of LTE/3G/2G.

That just gives 3G or 2G. I'm looking for HSPA+ 3G.
Well anyway I downloaded an app called HSPA+ Tweaker, and I seem to be getting faster 3G speeds. (7mbps). The "H" often turns into an "H+," which I didn't see before the app.

3G includes hspa+ (h+). and hspa (h) means 3g. I don't recommend using 3rd party apps for such basic things.

When you set your device to 3G from settings, it will automatically switch to H+ depending on what you're doing on the device.
A 3rd party app is not needed for this.
