I think i have a faulty unit because i can not connect to the internet at all (although it worked last sat morning when i got the unit but i did not try again until my number got ported)i have tried it on GSM only and checked all the settings over with the guy from T-Mobile and they are ok but if i put my sim in my Jam i get a connection with no problems.
The guy from T-Mobile says it may be beacuse i am on the fringe for UMTS reception but i get the U symbol and 4 bars on the strength meter but surely it should go on to GPRS if it can not get reception on UMTS as it would do for phone calls anyone any ideas ?
Start>Settings>Personal Tab>Phone>Band>"Select Network Type" and change to GSM (it's probably on Auto), then ok it all.
If you now connect over GPRS (which is what the above is to do - force it not to use UMTS at all), then you're ok.
Next thing is to go to a UMTS strong area, and do the settings but set back to Auto and see if u get 3G connection.
Hope it helps.
i just get the message ''warning:unable to change GSM/UMTS Band, please try again later''
thanks anyway
hey all
i've got a problem with my droid pro in eu on gsm/umts network.
when i'm roaming and use gsm only (no umts) my mic and speaker are dead. i can make a call and receive it, but i cant hear anything and caller doesnt hear me. display shows seconds have past so line is opened. i can even receive sms and mms just fine and send them, only cals dont work.
if i change from gsm to umts only, then calls work fine. when im on home network everything is ok.
funny thing is, that if i make a call on roaming in umts only and then change to gsm only i can receive first call, then it's all blank again.
i have stock rom
tnx
teva
probably the problem was with the network where you was located. did you tried another network?
my droid pro works nice in roaming, in both gsm and umts.
I am facing a similar issue.
2G 900/1800 Mhz -- Voice & Data Work fine.
3G 1900 Mhz --- No Voice, Phone re-boots. Data works.
So I have to use the phone in GSM only mode.
I am on 2.3.3 / Verizon 4.6.4 update.
My new operator have same issue! (no with the old operator!!)
In a specific location i can't make/receive a call in only 2g (i can send/receive sms and data traffic is ok)... But if I switch in 3g i can do everything...
For my operator it is an issue between sim (by ORGA) and droid pro and so I'll replace my sim...
I didn't find non ORGA sim, but i have bought a dualsim adaptor, for seeing... Nothing...!
On my operator (TIM), when i'm on edge in only same locations, i can't make/recivie calls... Not with my ex operator (wind)..
But... you can try to compose on your dialer ##7764726 then call, then password 000000
verify
06 test mode
next
next
service option switch to 13k, or others, then back...
Make a call, or try this configuration
if you restart your phone you must reselect this...
Tomorrow i'll try...
My new LG G2 D802 seems to only want to conect to GSM, if I have it set to any other setting like GSM/Wcda auto, or LTE etc it wont even connect to GSM let alone the other networks? To be clear i can use the phone set to GSM, but not when set to the other settings, just keeps searching for network
I am in New Zealand on Vodafone network which is
2G - 900/ 1800 MHz GSM, GPRS
3G - 900/ 2100 MHz UMTS, HSPA, HSPA+, DC-HSPA+
4G - 1800 MHz LTE
so I think the phone should connect shouldnt it? I am in 3G/WCDA coverage (not in 4g currently to try)
Any ideas?
the phone is stock rom, rooted, Xposed etc, Kitkat 4.4.2
Thanks
Edit, I just clicked network operators and searched and it came up with Vodafone Gsm which i have selected. So i take it my phone cant see a 3g network?
I think I have solved it. I went into the hidden menu and changed the modem settings to my carriers frequency instead of auto. So fingers crossed. II havedone a reboot and it is still working too.
So I had 3g for the day or so and then its gone again, I tried my wifes sim card which is on a different network and seemed to work, so i will get a new sim card for myself and hopefully be ok. my current sim card works ok in her phone, it just struggles to find 3g in mine for some reason.
Got a new sim card now but it still struggle to find 3g maybe because I'm not in a main town centre but I should still have service here as I am in there coverage area and my wife gets coverage on her phone
Tried updating to lollipop but problemremains. It is disconnecting maybe because of poor 3g reception but then struggles to connect to 2g again. Only solution to have working phone is ro have it set on gsm only all the time. Not good
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?
