Hi,
I am unable to use 3G on htc desire. I have set the correct APN. The problem is that when I choose "WCDMA" as the network mode, it automatically switches back to "GSM only". The place where I live has no problem with 3G availability. I feel the problem lies more with my handset. Can someone please help ? Is there anything that I can do to get rid of this problem. My phone has lost its warranty since I unlocked it.
Have you tried any other operator sim card? It's a good troubleshooting to do when this kind of problems happen...
Had problems like that before and it was an incorrect APN setup.
Thanks for getting back. I tried with a different sim and a different operator. They were also not successful. APN setting is perfectly right for the current sim. The APN settings were given by the operator.

Are you using any kind of widget to switch APN on / off, 2G/3g ?... I noticed that for example, Widgetsoid can mess with 3g connection so much that sometimes you need to remove it and reboot the phone so you can get things working again.
Try using another SIM card too. It may give you a clue on what's going on: wrong settings / card with no data activated / etc ...
I am not using any widget to turn on/off the 3g. EDGE services work on my mobile while 3G is not working. If I use the sim card on to a different mobile, 3G works fine without any problem. Tried using another sim card with 3G data activated and that also did not work fine for me on HTC Desire.
Need help guys. Hopefully this is okay since I'm using the S6 regular Dual-sim Philippines model. I'm using 2 sims (Globe and Sun network) and I always use my Globe network for mobile internet since it's faster. Now, when I use the LTE capable network for mobile internet for a couple of minutes (possibly hours as well), both of my sim cards would suddenly shut down (their mobile icon turns hollow, mobile internet disconnects. Sorry I can't provide the screenshot since i forgot while making this post). After a while, both networks will have their signal back and I can resume browsing again. This usually becomes a problem when i play online games since the game constantly checks for a working internet connection and it cuts me off the server if i'd lose my internet for a few seconds. What i've tried is that I'd turn off the other sim card (Sun sim card) but since I also use this sim for communicating with people, I can't turn the sim off permanently. Can someone please enlighten me on what to do or what might be the problem? Is this supposed to happen to the dual-sim variant of the S6? Hope you can help me out guys.. Sorry for the long post though.
TLDR: Using dual-sim variant of S6 (Philippines). Using two sim card networks (one for internet, one for texting/calling). When using mobile internet (LTE mode) for a couple of minutes or hours, both sim networks would suddenly shut down and I would lose my internet connection. Turning the non-internet network/sim off somehow fixes the issue but I need both networks on since people would call me at the non-internet network sometimes. Is this expected from a dual-sim variant or is there anything i could do to fix this. Thanks guys!
Is VoLTE activated?
a few days ago I switched from cm to AEX 7.1.2 on my moto g. Whether that has anything to do with it I don't know.
Anyway last night the phone was working fine then this morning I see that the cell network is disconnected and the phone doesn't see the simcard. However when I put in another simcard from a different network it works normally. I switch back to my sim and it works for about 20 seconds where I can make a call or text then it shuts down again and dowsn't recognize the sim then does again once I have switched the sims but only for 20 seconds. I don't understand what is happening to the phone and why it is doing this. I need help. I have tried picking different network modes from the list after inserting this code #*#*4636#*#* nothing has worked so far. I haven't systematically gone through each one at a time yet and the list is quite long. I haven't seen a list of modes that long before there are over 10 of them from auto prl to scdma etc... Some of them I have never heard of like the scdma one. wif and bluetooth are working ok if that means anything. Thanks for any help
Also when I go into settings the network section is greyed out and under prefered network type it says Invalid Network Mode (-1) Ignore. I only tried changing the modes when this problem arose my changing these modes was not the cause
i've had similar issues, when i skipped using mobile data for a long time, my non-data SIM would dropout intermittently. i changed SIM slots didn't solve it either. other SIM was fine in either slot. just before replacing what i thought was a faulty SIM, without turning mobile data on, i just set the problematic SIM for data. that solved mys issue. however, running mobile data on back on the original setting didnt cause any more issues either.
I was traveling to and from US and India. 2 Days back when I entered London airport for US, my mobile did not show any signal what so ever. It was no service. It was working fine when i boarded the flight in US.
Now following things I have tried according to my knowledge
1. I tried disabling the sim card, changing from 2g-3g- 4g. No improvements.
2. I went to menu by *#*#4636#*#*, and trying radio on and radio off. Nothing
3. I suspected that antenna is damanged and it hardware problem.
4. But then this wired thing happend, while playing around when both the sim are active, I turn of the sim one, the mobile data is switched back to second sim. Then when i again switch back the sim 1, it is automatically configured for 2g. It gets signal, I can make calls and it works good. Moment I switch the mobile data to that sim the network vanishes and back to no service/emergency calls.
5. I figured that there is some problem with the sim, so I inserted that sim into old samsung grand mobile which 3G phone. It works flawlessly.
6. Tried other sims in the moto G, 4g dosent work for some sim cards.
7. By reading on I found that lot of people have this problem and have solved it by flashing firmware. I tried that too. Tried stock rom, new osprey 7.* Nothing seems to be working.
Any thoughts and comments are welcome. I am kind of frustrated by this small bug. Might be lapse on motolora part. If someone is still active in this community please help, reply.
For those on dual sim, does data on the secondary sim ever get used. In Sim Card Mgr there is a toggle to use it during a phone call but other than that , say my primary data sim is poor, I wish it would use the one with the better connection automatically but I do not think this is an option

I have a Samsung Galaxy Note, SM-N986B/DS.
No, my experience is, you can't set data usage to automatically,
But why don't you just choose Sim2, for data usage.?
While back i had 2 x Sims in my device.
(One Sim is a just a data Sim, loaded with 10 gigs data each month )
The other Sim only had 1 gig data on it, each month .)
I set my preferences as follow in Sim Manager ......
Calls.... Sim 1
SMS.... Sim1
Data ( mobile)... Sim 2
Worked fine.
No issues.
If i switched my mobile data on it would
use Sim 2 data.
However,
I have since changed my setup.
Took second Sim out of phone,
as i experience
"more battery drain" (overnight )
than when i was using
only one sim and/or sd card.
Good luck.

Yes ,it's was just the opposite situation for me ,where i had more data on Sim 2 .
However,overall i guess it never worried me, as i am 90% on wifi .
I also noticed ,more battery use age of keeping mobile data on ,than wifi.
I guess the only option left ,would be to manually, change to preferred data Sim .
As far as i can remember the best option ,
( when i had 2 Sims in my phone )
i would swipe down to expand phone quick settings
and my Sim preferences , showed ,just under the phone ,quick settings icons .
I would then long press on the preferred data Sim choice and change it there.
It was better than going all the way to Sim Manager .
Good luck

Hmmm, the battery thing is interesting. I've tried so hard to get dual sim, flashing TMB onto Unlocked but now the battery thing is a bummer. If that is what causing it. I just turned off 120 refresh rate to see if that improves battery
In Quick Settings I see where I can click on one of the sims on the top and it takes me to the sim card menu but I wish it were just a toggle instead of taking to the menu

Firstly,
Yes, only thing you can do
is "toggle" it manually, like you described.
Secondly,
with 2 x Sims in my phone
i found that my average "sleep" over night
was example......
+- 12 % battery drainage, over period of +-8/10 hours (sleep.)
Further the way i see it,
is that even with phone in
sleep mode, it still trying to get better signal reception.... x 2...? whilst
This i checked via Betterbattery app.
Secondly,
I am back on one sim.
My average sleep overnight is
8 % for 10/12 hours sleep.!
Bottom line,
It's your phone.
That battery diffs, is no big deal...
For me it was an irritating issue. thats all
If you happy with 2x sims
keep it that way!
Good luck

Previously, say I had Sim 1 for data and Sim 2 for calls and i got a call on Sim 2, then Sim 1 was unable to access data but this has now changed with N20U
If I understood this correctly then I think my device is different cos regardless of which Sim is primary or secondary, I have an option under settings>connections>mobile networks> allow all Sims to use data in calls, which I can toggle on or off. I have found selecting this allows the other sim to use data which was not possible in some earlier android versions.

But not when I'm in a call. I needed to use data from my secondary sim because I was in a dead spot for first sim. I had to go to sim card menu in settings and change primary sim and then change it back eventually. I did use the shortcut from the pull down menu but I wish I had a toggle , ideally from Nova Launcher
I am interested to purchase a SM-N986B DS for my dual sim work/personal cell in the US near NYC. I have metro PCS and Verizon. Will this phone allow verizon to operate as the second sim? It would be a non-data sim. I know it is a GSM phone and not CDMA but also read that the LTE bands may be compatible at 4g/5g. Curious before I take the dip to buy and find out it won't work...
