So, i have bugged folks on this forum about getting 3G to work on other carriers, and it turns out - it does work! At first i found out my settings were set to GSM only, but now i also found this weird inconsistency possibly a bug.
If i have Data Off after using 3G or GPRS for some time, when i turn it back on, phone would not connect to data service. After enabling it will simply time out.
I found that if i switch from GSM to WCDMA, and than back, 3G network would connect and work.
I don't know if it's specifically my phone, or a bug, so i'm just throwing it out there.

What carrier are you getting 3G to work? I doubt its working if its anything that doesn't run on tmobiles bands..the icon will come up and stuff but your either getting edge speeds or not getting any connection. I've had this phone show me 3G with full bars and just time out.. I can eveven put in a sim with a sidekick plan or other data plan and it shows 3G but it does not work
Well, i'm overseas and i have used it on Russian carrier Beeline and carriers in two other countries. Now, i do set my connection to WCDMA only, which gives me 3G icon. When i set it to GSM only, i see GPRS icon show up.
So, it does work, i use fring, online radio, google maps. But as far as speed concerned, i have not tested it.
Just ran a speed test using Speedtest.net tool, I get 3951kbps download, and 655 upload
thats 3G
Hey there, I enjoy reading this forum but I had little to contribute with as I am an android noob. So unfortunately my first post is a question forced by the fact that something is wrong with my DHD Thank you in advance for your advices!
The problem is - when in areas with low 3G coverage the phone keeps on searching for 3G for too long instant of seamlessly switching to 2G, which often has full signal bars. This way the phone acts as if there was no signal and sends incoming calls to the voicemail even though all it has to do is to switch to 2G as soon as 3G gets too weak.
My previous phones had no problem with this. In my city the 3G quality varies from area to area but the 2G coverage is perfect almost everywhere. So I used to be sure that my phone never really disconnects from the network, it only might have dropped the 3G signal in favor of 2G while keeping the calls and everything.
I know I can disable the 3G and stick to 2G and EDGE but this way using full data capabilities of the phone turns into pain instead of pleasure.
Just to make sure and to show I did my homework, this is NOT:
- the death grip case
- a network related problem /I suppose.../
- a problem with data connection /I have never run into any problems with this/
My questions are:
- is anyone of you experiencing this?
- is there a way to force the phone to hand over the connection from 3G to 2G quicker without "blind spots"?
- does any custom ROM improve this? /I am running the latest stock HTC DHD android 2.2 with Sense/
- is there any hint that android 2.3 gingerbread should fix this issue?
Thank you, hope to find a piece of good advice here!
I`ve found this service menu and I switched the preffered network from WCDMA preferred to GSM AUTO PRL. will see if it helps.
I havent noticed any more problems since I did the switch. I think it helped. I cannot be 100% sure but I think it did the thing for me. I forgot to mention that I also switched networks mode from Auto to European but I think this has nothing to do with the issue.
fortuneman had my answer. To access the service menu on the soft phone keypad enter *#*#4636#*#* and its under Phone Information.
Switching from 2g to 3g works seamlessly. But the other way around doesn't work that well. Nothing to do with the phone. Just the net tech that has its flaws. If your in a call and switch to 2g, the call will most certainly be disconnected.

I'm on the Three network, have an unlocked HTC desire HD with 17 m2 radio.
Normally I get terrible signal in the flat that i live in, its a granite building in Aberdeen. Occasional the signal is around 1 bar, sometimes grey, and most of the time its X.. (no service), but i still manage to get 3G or H. When looking at the APN settings and specifically at available networks when doing a manual search, next to 3 is a green star which I assume means it's connected to 3 mobile network. But sometimes i get amazing signal, full bars, which puzzled me! so I looked at the available networks and next to 3, there was no star, so i tried calling a number and it rang and came through. I also tried using mobile internet when in this "good coverage" state, and google would not load (G is displayed in the notifications bar). After a while, the bars would drop to 1 or grey, and i would then get H or 3G, and google loads again. What's going on? and how can i take advantage of this when i have no signal.
try and find the app called open signal maps
that can be used to see where the signal-towers are
and how good the signal is
or use this site and search your adress

The antenna is really wierd.
Normally I only get 2G connection.
But if I completly take my hand off the lower cover and lift the phone up a bit for a better signal, I get a 3Mbps connection, though as soon as I lower my phone back to normal the 3G signal is completly gone or gets really bad (zero bars and lower than EDGE speed)!
The antenna in this phone sucks really bad, my old Nokia phone atleast had a stable connection.
This is very bad news... I was considering DHD, but if there are isseus with gsm signal than I am really worried... Is it also happening on the stock ROM?
As long as network coverege is good you should be okay.
I swaped my SIM card with a friends and with better coverege, 3.5G worked good (solid 2Mbps), only slight drop if SIM cover is completly covered, which doesn't happen in normal use.
I just can't understand how I can get such high speeds with my SIM while on a badly covered area. haven't tested how well other devices pick up the 3G signal (my old phone wasn't 3G yet)
I'm still using stock ROM btw.
Have you tried a different radio?
People are reporting different results with them, so might be an idea to play around and see if anyone of them works better for you
I've tried the new Orange radio and I'm getting better signal, although threes coverage isn't great I would expect the device to seamlessly change between 3.5g and gprs but it doesn't it'll get stuck on hsdpa network until the x appears and sometimes it'll go to gprs and go back to three bars. Before it would be on x all the time and that's probably why the battery was quite ****. 3g doesnt penetrate buildings very well and I live in a granite building so would explain why I get better gprs signal. I just wish the antenna was smart and changed seamlessly.

Hi,
Using a N910F with T-Mobile UK, default APN settings for EE. The phone was sold by O2.
I'm having a hard time maintaining a connection to the HSDPA network when out and about, far more so than with my previous phone with the same carrier in the same places. The signal will often show as full whereas the connection isn't established (based on having the 2 arrows highlighted) under the H icon. Once the connection is dropped it takes a long time to re-establish.
I've searched and read about other users having poor reception quality but this seems to be a different issue to the one I'm trying to resolve.
I haven't seen any alternative radios available for this phone yet so not sure if I just need to wait a while. If anyone has working APN settings for T-Mobile UK and can share them that would be really helpful.
Thanks for your advice!
Hi Everyone,
I'm usually just a reader on XDA, but I have found a problem that appears not to have been solved and wondered if anyone had any insight.
Problem Summary
When in an area (or network) with only HSPA and UMTS (strong HSPA/UMTS signal, but with no LTE or 2G available), the phone will drop from H+ to 3G erratically, always dropping the data connection. Traditional phone calls are not affected.
Detailed Description
I have a OnePlus Two and have 2 SIM cards. My first SIM Card is with Bell Canada (Virgin), and the second SIM Card is with WIND Mobile Canada.
Neither Bell nor WIND operate a 2G network, so the lowest the service can fall to is UMTS/3G.
Initially, I didn't notice the problem because Bell also operates an LTE network, and there is no problem with dropping the data connections when on LTE.
When I switched to the WIND SIM card (which only operates HSPA and UMTS), I noticed a problem where the phone would initially connect to H+, begin downloading whatever is needed (say, streaming music), but then part way through the download, the connection would switch to 3G, and the data would effectively stop. Within a minute, the service would jump back to H+ and download some more, but this cycle would continue (H+ --> 3G --> H+ --> 3G... ), with no way of knowing 1) how long the H+ connection would last before dropping to 3G (usually less than 30 seconds), and 2) after dropping to 3G, how long before going back to H+. This problem makes the phone almost useless when there is no LTE.
The most obvious troubleshooting I did was move to locations of better signal but I quickly ruled that out, as nothing seems to remove this problem. Other things I tried was to: move locations in the city, reboot phone, hard reset phone, flash most updated version of Oxygen, unlock bootloader, root, try the HSPA Keepalive app, swap SIM1 to SIM2, and many other things.
I originally thought this was a network issue, but I put this WIND SIM in another phone and there was no problem in any way that resembled this problem.
I also ruled out this being a network-specific problem, as I have taken a trip with the Bell SIM to an area where Bell does not have any LTE coverage (only HSPA and UMTS) and the same problem occurs on Bell as with the WIND SIM.
I have found people who had this problem on the OnePlus One tend to recommend using 2G to stabilize the connection, but this is not possible on Bell or WIND. That solution also would not provide adequate data speeds.
Remember this problem only affects data connectivity, as 3G traditional phone calls have no problems.
Question
Does anyone know if there is a way to adjust the conditions when the OnePlus Two will choose to switch from H+ to 3G?
Does anyone have any easier suggestions?
Thank you all in advance, because this rendering this phone almost useless when there is no LTE coverage.
I believe your problem is that phone it's dualsim standby, that means only one modem that alternates signal for both sims, I think normal would be alternating from faster network to slower network on sim without data.
Having to change to g3 between sims theres something stoped in the modem and data connection is also stopped.
You have no problem with voice calls because other sim is automatically turned off and unreachable.
There's nothing you can do if you're forced to only 3g on both sims
By 3g I mean 3g or h+ which to my knowledge are the same
Hope I was helpful and not wrong or more confusing

Thanks, I will try disabling the second SIM to see if there is a bug with the dual-sim...
What it currently does with the second SIM is it either shows "R" for roaming or just emergency only, but perhaps there is a software issue so I'll see if disabling the second SIM makes a difference.

Though strange, this workaround fixes the issue. Thank you to fburgos for the suggestion!
So just in case anyone ever finds this issue creeps up on them, the solution is to DISABLE the SIM you are not using. It's not the most convenient workaround to swap SIMs, but the other SIM will be in Emergency Mode, so it really makes no functional difference.
On the technical side, it does appear that there is actually a bug in Android for a very uncommon network configuration. It will only appear in this exact configuration:
SIM1: Network has HSPA/3G only, no LTE or 2G to move to
SIM2: Network also only has HSPA/3G with no LTE or 2G
The non-data SIM does NOT connect to a roaming network (connects with "Emergency Only") - if it connects to a roaming 2G network, this problem does not happen.
The data SIM connects to HSPA/3G
Both SIMs are active
I'm not sure if this will happen anywhere else in the world other than having a WIND Mobile Canada SIM and Bell or TELUS Canada SIM
If anyone has insight on how to report this to Google, or someone else who can confirm my theory, that would be great!
Try this:
1. You need to make sure you have the correct LTE APN selected in mobile networks and LTE as preferred type.
2. Go to dialer and type in this: *#*#4636#*#*
3. Phone Information
4. Set Preferred Network Type to: LTE/GSM (PRL) - you an play with which one you wanna use but the one I said works for sure. on other roms I have" TD-SCDMA, GSM/WCDMA and LTE"
5. Now click TURN OFF RADIO and wait WAIT few secs. will that button turns to Turn Radio ON
6. Now TURN ON RADIO and wait
7. when u see the triangle for the signal is back, at least black , go down and lick SMSC REFRESH then UPDATE.
8. now just go back to APN settings and go into your LTE APN
9. Change Bearer to LTE

I have the same problem. Do you already have solved it?
I use only one SIM card so it is not a problem two cards.
really you do not have this problem? if no one knows the solution?
compared with my htc butterfly 2 and another low-end android, one plus 2 running latest Oxygen OS has serious connectivity issues. I compared the signals strength using same sim card in same location (including being connected to the same tower) and One Plus 2 keeps dropping the connection and has really poor signal strength. I have tried the *#*#4636#*#* and tried different network modes, but none of them are helping. Its a real disappointment that the basic feature of this phone is screwed up.
I have tried with CM13 as well. Any ideas if this is a modem version issue?
