Hi everyone, I searched for a solution for my problem for a very long time, but found nothing. HOX has many issues with gsm network or signal, but mine HOX has a very strange issue with network mode switching. For example, I'm on 3G now and I set the WCDMA prefered in *#*#4636#*#* menu. When 3G becomes unavailable, HOX tries to switch to 2G network. But instead of switching to 2G, I get "No Sim card" icon and after ~30 second network icon disappears. I have to reboot the phone to recover the network. I made some tests and found, that this is not the hardware fault. I tried to change the radio RIL to any available and there is no difference. For now I don't know what to do, what else can I do... I will really appreciate any suggestions.
I can record a video to get things more understandable.

Hello guys,
I´m a happy Desire owner since 2 weeks now and have a little question.
I noticed the following:
In areas with bad network coverage, signal shows (E)dge, or if it´s even mor bad it shows (G)PRS. That OK.
But in areas with good coverage it shows 3G (UMTS) all the time, and only if I transfer data, eg syncing email, it´s showing (H)SDPA, and switches back to 3G.
Is that normal?
I wonder as this is my first android device, and all my older WiMo phones where showing (H)SDPA all the time.
I´ve read else where, that often changing networks need a lot of battery power.
Oh, I´m using T-Mobile in germany with an unbraded Desire running 2.2.
I noticed this also with 2.1
Thank you!
Perhaps the question was´nt clear enough ... sorry.
I mean, I this the same at your phones, or do they show (H) all the time?
Thank you again!
Mine does this too.
If you want to lock to a single network type *#*#info#*#* in the dialer.
In the UK mine shows hsdpa most of the time, sometimes gprs when roaming. It does not show anything when on WiFi, just shows the bars. If you press from home screen the menu - settings - about phone - network, then you see the signal strength and type of signal .

Thats what I thought it should do ... so it seems my SIM is having a problem.
Yesterday I put a friend´s SIM in it (also using T-Mobile) and it shows H all the time and never 3G. If Network is bad it switches to E and then back to H.
Now I´ve ordered a new SIM, so lets see ...
OK my SIM is around 12 years now ... 1998 ...
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.
Hello all, I'm hoping somebody will be able to help. I've got a desire HD on 3 UK (I haven't contacted them coz tech support is useless and I don't want them to know I'm on a custom rom), running LordClock's ICS 8.6.1, My data works fine on 3.5g but as soon as phone switches to 3g I get no data at all. I've tried various roms I've Googled for hours and found no solution. I've checked APNs and tried various versions found on web, I've tried changing the WCDMA preferred option in hidden menu, I've cleaned and reseated the sim, and tried turning airplane mode off and on The annoying thing is data has worked on 3g on Ice cold sandwich in the past, I think v7.3. I was wondering if it had anything to do with build prop and have changed and added various lines but with no success. Any advice or suggestions would be greatly appreciated and thanks will be given to anyone who contributes. Thanks.
What do you mean by switching from 3G to 3.5G? There's only a toggle to switch between 2G and Automatic mode (2G/3G) in ICS right? How are you switching between the 2? Also what is this hidden menu where you switch to WCDMA preferred? (Just for my knowledge. I don't know about it). Does it work for you with different ROMs?

Hi sashank, I meant just that when I lose a 3.5g signal and it automatically drops down to a 3g signal I'm not switching it myself, and if u go into the dialer and type *#*#4636#*#* u get a hidden menu called Testing with gives u info bout network or battery, check it out, the WCDMA option is in Phone info.
Hi, I have exactly the same problem. just to clarify, I am on the 3 network too, and when I have H (HSDPA) signal, the internet works..and works well. however as soon as it changes to 3G..the internet doesn't work at all
you should consider flashing other radios
hey all,
I have att on my fire phone , and every now then(atleast once a day) I lose service. It would say searching on the signal bar and it never finds it lol. I would have to restart the phone and then it reverts back to normal. is anyone else having this issue?
I'm guessing it's the fact that LTE has lower signal quality than 3G and
once you force the phone to 3G (once per reboot) it will never disconnect.
LTE is used only for data, when you make calls it will switch to 3G anyways,
so call your phone while it's in LTE and you should notice signal improve ...
To switch do this:
Same as dialing *#*#4636#*#* but this is easier to use:
play.google.com /store/apps/details?id=diewland.testing.phone
Go under Phone Info, then select 3G auto I believe, 4th down from top.
Also, contact Amazon support (right from help on your phone) if the above fixes it.
Tell them you want settings for disabling LTE added to the phone,- I did that and they
said they've submitted to developers, but I guess it's best if more people request this ...
I just changed my SIM Card from a 3G SIM to a 4G SIM recently. However I met an issue, whenever I use the 4G Mobile Network for too long (like 1-2 hours), the phone will suddenly lost all signal for 5-10 minute before recovering the signal. The signal bar is empty, and it appears the "Emergency Call Only" stuff. Is it just me or everyone is encountering this problem?
I have no problem at all when restrict the phone to connect 3G/H+ network only, it only occurs when I connect to the 4G network for a period of time.
My friend that uses the same telco with me doesn't have such problem (disconnecting/no signal at all) when connecting to 4G network, and it doesn't seems to be the antenna problem since the problem does not happen when I connect to 3G/H+ networks.
What might likely be the cause? Is there any solution to this?
Sorry for bad English, not my native language
(I live in Malaysia, and using UMobile Telco. )
Now that you mention it, I have pretty much the same issue of losing signals, and the problem hasn't occurred ever since I stopped using 4g. I didn't notice it was because of that, because I changed the phone too while changing the sim. I have marshmallow by the way. Don't know if that might be linked to the problem.
