Way to force which phone network to use?

All,
I have a micro cell from AT&T at my house because I was getting dropped calls. So when at home my phone network is AT&T MicroCell (which goes through my home internet). But on occasion when I am at home I would like to switch to good old 3G because everyone in my home is using the internet and it is slow. Currently I have to go upstairs and unplug the microcell. Is there a way to force it use one or the other when I want from my phone?
Thanks.
Steve

Press *#*#4636#*#* and then go to phone information and scroll down to Set prefered network type and choose your liking.

Awesome.. Thanks. I will give that a shot

I attempted the #*... and although it gave me those options none of the options got me off of the at&t microcell. Any other ideas?

I'd be interested in a solution as well.

Completely didnt read the last two sentences. Nothing to see here.
You could always give qos priority to the cell data and bypass the need to disabled the microcell.
Of course I am assuming you have a router capable of doing so and you have the required skill.

[Q] Nexus S 4G - DATA DROPS

I have been having this problem with both of my Nexus S 4G ever since I got them 2 months ago.
My data drops out frequently and takes a while to get back up. If I have 4G enabled, then I have to manually reconnect it as it will not do it on it's own. This happens inside AND outside. Driving down the road or just standing in one spot.
I've tried all of the radios (basebands) and about 7 different ROMs and versions.
I've refreshed the data profile, PRL, and even tried the roaming Verizon PRL and Hybrid PRL.
Gone back to stock and tried everything from scratch. Still the same problem.
Dallas/Fort Worth Area
Network: Sprint
Baseband: D720SPRKE1
PRL Version: P:40447
I contacted Sprint and they just told me to update the profile & PRL.....
Any suggestions?

I'm not familiar with the CDMA nexus s, but are you able to change APN's? At one point I'd be able to connect to 3g (I have an I9020A), but every minute or so it would drop, so I fixed up the APN's for my carrier.

iv had a few data issues
forcing PRL and account updates has fixed it a couple of times
i'v bought used phones that iv had
to have sprint force update
im on LC1
[altho i cant tell any significant difference here]
and my prl is 61086
[a business account]
im currently on slim
make sure your mobile network
is set to roam
is not set to home only

Am I the only one with this problem? As I'm typing this I lost data but still had 3 bars. I never drop calls but only data.
Help please. This is driving me nuts.

no
i go thru periods of it acting bizarre
try disabling wifi and reboot
this USUALLY fixes mine till wifi is re-enabled
and i drop the sprint connection a few times
riding around
it then fails to re-acquire the IP address.
look in your status and see if you still have an IP
when your data fails
fwiw

I never use Wi-Fi. Ever.
Happens while using both 3G and 4G.

4G is worthless here...
i dont even bother with the switch
does it do the same thing if you disable 4G?

I almost always have to use 4G (if possible) since 3G speeds are slower than dial-up.
I've tried rebooting and leaving 4G off, and still the same. Even tried going back to Gingerbread.

If going back to GB doesnt help, maybe it is hardware related?

In the original post, I stated that was one of the things I've done.

have you checked to see if you have an IP address
when data fails?
mine shows "unavailable" when it's wonky
and wont re-aquire till i reboot.
i'v seen this on 2 phones
off and on including on oem 2.3.7
fwiw

I have the same problems. From what I understand, its a problem with the hardware. I can confirm that's probably the case, because I've tried many different ROMs (stock, cm, etc...) and they all have the same radio issues (3g/4g and wifi)...

I have an NS4G in the DFW area and haven't seen the issues you're reporting. I'm currently on 4.0.4 with D720SPRLC1 baseband. Maybe I'm just lucky and have a good signal at work and home. It's very rare that I find an area of DFW where I don't get any data signal at all. Not sure what to suggest.

I get random drops too and i hate it. My 3g speeds are fairly good even above 1 mbps. Highest i ever got on 3g was 1.51 mbps

Mine will lose data if I'm in a coverage free area for an extended period of time, when I'm back in range 3g icon will show up just never reconnect. A reboot fixes it

Certain Areas
There are certain areas where I live that data just disappears. Although this is just a network thing I believe. It's weird though when I am driving it's like a 10 second drop and then all is good. Hope you get a solid fix!:victory:

Backup 4g Partition
REMOVED - was a bad idea.

I've actually replaced BOTH of the phones with brand new NS4Gs and they shipped with ICS.
Still the same problem.
This is driving me nuts. I was driving and trying to download Maps for the new phone from the Play Store and it took 6 tries. Kept saying RETRY.
What I've come to believe is happening is:
When 4G connects, 3G disconnects. When 4G drops (which is does frequently), 3G has to reconnect.
***Is there a way to keep 3G "on" in the background while 4G is connected?*** Maybe a way for the radio to transition back and forth?

hi has anyonr else eperiance this same issue. whenever I go to an area that has little signal or turn the wifi off and on my phone resets to 3g. I have to keep going into the apn settings and change it from EHRPD to 4GLTE and then restart my phone. I cant change any of the settings oe delete extra APN's so I posted a screenshot and im hoping someone can help me out. Thanks

not that it helps much, but this is an issue seeming to affect alot of us. I havent been able to correct it yet however. If I find anything out I'll post it.

Just put on airplane mode and turn it back off. Boom your done.

Is that an app you use to change those settings or is that buried somewhere?

I just checked as I haven't seen it yet either. Settings, More settings, mobile network, access point names
Kind of cool. Mine showed the first option chosen but it hope between 3G and 4G as usual. Choosing LTE made no difference for me. I have virtually no 4g signal where I love

Airplane mode is a feature of the phone and turns off all radios. You can hold the power button and choose airplane mode or use the quick toggle in the notification window. Since it sounds like you may be in an area with weak 4G, you can also use an app called Phone Info to set it to CDMA auto (PRL) under Device Information. You can also change it back to LTE/CDMA/EvDO if you want it to switch as normal.

With the Verizon S3, is there the need to do *228 (or *22899) ? I did this every so often on my old HTC Incredible.

Doesn't work on LTE devices. A reboot essentially does the same thing. Some have recommended pulling the battery with the phone on, removing the sim card for about 30sec and then putting everything back in.

Thanks, I know what airplane mode is, wasn't sure where the APN setting was. I will look in to phone info though.

Are you guys also experiencing the "No Sim Card" and "No Network Connection" issues?
Or is this an entirely different issue?

When this phone goes to 3g, it does seem extra bad on how long it takes to switch back to 4g. i have areas where i live where it goes to 3g when going in between hill (less than a 50 foot stretch) and it will not go back to 4g for over 10 minutes if i dont manually do it. Not to mention my LTE never goes above 10 mbps on the best days

Somewhat related...If you use Anycut to create a shortcut to IOTHiddenMenu, enter the ##DATA# Menu, edit. Under "Advanced", there is an LTE toggle, under "Other" > "HDR/1X" you can set the phone mode, and then under "Other" > "LTE APN Settings" you can somewhat modify the APN settings, reset and discard. If it asks for a password, it's 000000.

I gave these a try. I'm trying to find a way for my phone to favor 4G when there's a 4G signal, no matter how weak.
Yesterday I did a test, 3G with 3 bars vs 4G with 0 to 1 and 4G had consistently faster download speeds and shorter ping times. The upload varied from similar to 3G to slower.

probably easier said than done. The phone info app can force LTE but you lose voice and text.

Ya I found that out yesterday when testing speeds. I went to send a text then make a call and no luck
Otherwise 4G service where I live could be excellent at one spot then a mile away no service. If I had excellent 4G consistently I'd consider GoSMS which I believe has the option for data text and also a separate VoIP app
Ah well hopefully something will be figured out eventually. With a strong 4G signal 4G is considerably faster and more consistent than my 20mbps home broadband

send it back
I've had similar issues with my network. I had no 4G in 4G areas, but mainly my wifi would disconnect randomly and 3G also dropped to 1X a lot. I ended up having to send it back and get another one. So far no issues. Also the new ones have an "Updated" sticker on them. I think it was just a software update they applied, but I never got the OTA on my old phone.

Your new phone came with an already updated firmware version I535VRALG1 instead of the original version I535VRALF2.

I'm having the same issue with my second replacement phone... My first one was replaced for an entirely different issue (loose home button).
Did you get the "No Sim Card" notification and "No Network Connection" message?
I think I might have to return this one as well...

Not sure if anyone will have the same luck I have with the "Phone Info" app, but with it I was able to get my 4g service back and my phone is functioning normally again. Just open the app, select Device Information and scroll down to "Set preferred network type" and select "LTE/CDMA/EvDo" then get out of the app.. 4g should return shortly there after. When I looked at it, my device was set to "GSM/CDMA auto (PRL)"

Telstra One xl download problems

Hi all. I've had a search but can't find much on this. A friend has a bog stock Telstra one xl running stock jb. The data connection works fine except written she's trying actually download a file like a pdf attached to an email or an app from the market. When the download starts, the phone switches to hspa mode, as you would expect and then the download pauses before and data is downloaded and the phone switches back to 3g mode. The download never resumes. It works fine on wifi.
I've tried force closing the download and google play apps as well as clearing their data and cache. I've reset the apns to default. I've tried creating a new apn as directed by Telstra's config site. I've tried using different google accounts.
Apart from doing a hard reset, does anyone have any other suggestions?
Thanks heaps

Curiously, will it download on WiFi?
If so, I suspect an Apn setting or perhaps carrier side issue maybe, will phone surf net on data side of things?

Sounds like it could be one of two things.
It could be that when the phone sleeps (screen times out) it switches to a low-power mode to save on battery. (check settings)
Also, If the setting for WiFi sleep is set to always, it will hold a connection even when the phone has timed out.
Or, it could be your friends location. It could be right on the edge of having HSPA+ on the coverage map, thus the phone gets a low HSPA+ signal and switches to WCDMA.

Yes, the phone will surf fine on mobile data just won't download actual files. Everything works fine on wifi.
I've checked the apns against my razr hd on the same network. Some were slightly different so i changed them to match. No difference. I reset the apns to default. No difference. I setup the apns to the carriers specifications including a proxy. No difference.
I think she may have to do a hard reset...

The location makes no difference. I'm sure it's not that.
As for the sleep thing. That would affect all mobile data. But you can be surfing on the internet, find a file to download but then the download will pause straight away. So i don't think it's that...
Thanks for the replies guys.

Just as a further note. I just tried forcing it use the 2g network only and the same problem persists. It uses EDGE to surf but any download instantly pauses...
Strange. Is there any chance an app could be causing it?
Sent from my XT925 using xda app-developers app

Yes, even in its own settings you can set a limit. But I'd expect a toast notification to alert you of that an not be able to surf.
Sounds like something missing in the apn yet to me but that's my feelings on it. My telus uses two, only carrier that does that I know of, I get ok speed on one but with second I get very fast speeds.

I've had a very similar thing happen to me as well. It's not restricted to downloading though, it happens while surfing too. So I initiate a download or load a web page or load a page on the XDA app, it switches to HSPA, then it will drop back to 3g and the download goes nowhere. Usually opening a web page (or initiating some other kind of data transfer) will switch it up to HSPA again and the download/web page will resume. It's not a constant thing, only sometimes.
I happen to live in a house with terrible Telstra signal and it happens mostly here. Like I said it's only every now and then for me though. Is the signal strength ok where your friend is?
Sent from my One XL using XDA Premium

No definitely nothing to do with location. You can have full coverage at the problem persists. My Razr hd works perfectly beside it and the one xl supposedly has better reception (blue tick) although I'm yet to see any evidence that the Razr actually has worse reception. It seems very good. Must have come very very close to getting blue tick too...

[Q] Signal drop

Hi all
I bought a Nexus 5 yesterday. All good but today, the signal (that is, mobile signal) dropped and even with a flight mode on/off and re-scan for networks it did not pick up. In the end, I had to reboot.
It is completely stock 4.4.2 and I'm just wondering if this sort of thing is a common issue. The only thing I can think is I was definitely in a no signal "black spot" for maybe 15 minutes prior to the drop so it's almost like it "froze" and didn't want to pick up the network when it returned.
Thanks
James

Same exact issue, Sir.
It seems to be common, but I have minimized it by installing a custom ROM (I'm using the Cyanogen Nightlies) It is a known issue though from what I have heard.

I think Google will fix this issue on the next update,so don't worry,it's known issue,and enjoy your device!

set your "preferred network type" to 2G (even if "data enabled" is not enabled), you will notice that signal will be stronger

Thanks for the advice, guys. Like you say - as long as it's a known issue then hopefully a future update will resolve it.
For the "set to 2g only" advice - I only get the option of 3g or 4g? I already set this set to 3g only as I don't have a 4g data contract anyway.

Try flashing a different radio. It makes tons of difference on signal quality.
