So when I leave all the band settings to auto on the phone, it immediately connects to AT&T's 3G network and shows the "H" in the title bar it worked for a little while then calls stopped coming through, after a hard reset it works again with calls for a few hours, then it begins to fail.
If I switch the bands to GSM and manually select the frequencies (850 + 1900, according to wm) then it connects to the EDGE network, and I can make and receive calls as I please, no problems, except for the crappy network speed.
So someone help me out here please, is the phone defective, or is it not working as it should because of the lack of the 850 band? I know that AT&T works on either or but this problem has me stumped.
Other than this rather huge problem (phone that cant make calls), I absolutely love the Xperia and would hate to return and wait for another.
did you try to use the connection wizard to let the phone config itself?
after I put my iphone sim in it shows the H/3G icon on anf off all the time, while I can receive call I was unable to go online.... after someone suggested me to call att to update the imei on my account to the x1, I found that I still have to go to connection and change the setting myself b4 it can go online. you will have to remove the user name and pw in media net setting and uncheck the proxy server.
I guess my case is a little different than yours but I guess you can give it a try... good luck =)
Thanks, I actually haven't tried that since i figured it would be the same as what happens when you turn the phone on for the first time, when it autoconfigs.
if it say it detect a new sim and ask if you want to do the auto config then I guess its the same... but again I did need to change some settings inside the network config to make it work too... so I am guessing the "auto config" has some flaw in it
No problem with my X1i when I venture in a1900mhz area close to my home. I live in a small town in Ca. only 850mhz here. But in the larger Metro area around me... No Problems with calls or hspeed data access...
Stuart
Thanks for the replies, It looks like the Configuration wizard in the settings menu did the trick. It do something else that the autoconfig doesnt. The phone seems to work now just fine, although it doesnt hang on to the signal as well as my old k790a. The office I work in is an ATT dead zone and I could make calls using the K790a with only one bar, with the Xperia it either doesnt go through or drops the call.
Again this is better as it works now, just not as well as my old phone.
Also, scl_electronics, so you are saying the X1i has both 850 and 1900mhz bands? I had a feeling mine did too, but I thought it was put to rest that that wasnt the case with the X1i....
Sorry Aaron J,
i should have been more specific!! Where I live, 3G is only on 850mhz band so I don't get access..Just The edge network. When I venture about 10 mile away toward the major Metro areas..The 1900mhz band are used. So the H is displayed, but I don't have those access problems for calls or data!!
But i am waiting to see if they can crack the rom for 850mhz-3G access!!

Oh ok thats kind of makes, sense although I thought the X1i didnt have an 850 band at all, so what frequency does it work off then?
Anyways, back to my problem....I spoke too soon, it dont work on 3G switched to EDGE. I might just try getting a new sim card, mine is a Cingular one from 2005, that has been in at least 4 different phones now including the X1i.

Well out here in Ca... 850mhz gsm/edge is used ..So I quad band gsm phone is handy!!!
Stuart
Yes it is! My little problem is a little confusing though as one thing I just realized that I didnt say before is that the phone has no problem connecting to the 3G network using HSDPA. I get full bars with the H icon pretty much everywhere in my area and my data speeds are very good. So I can surf the net, download programs, watch high quality youtube videos using the app in touchflo and even send and receive texts just fine.....just no calls when on 3G. I'm hoping its just setting somewhere and not a faulty device.
I live in Raleigh NC by the way so maybe it could be a faulty tower?
Well when venture into Stockton Ca. my phone switches to 3G-HSDPA:1900MHZ Without a connection hitch....
Have you tried a soft reset......
But when all else fails Hard Reset to the Rescue!!!
Btw... in several of my ppc-wm units when restoring to OEM setting(hard reset) there has been many time the process had a problem. So something would be screwed up!! So when You don't succeed, try another hard reset!!
Good luck,
Stuart
hey i was wonder if your problem is HSDPA/HSUPA being on, i have at&t also and it worked for the first few weeks fine with it being on then all of a sudden it stopped and couldn't connect to the internet, before i had the H/Edge showing up and also my email never updated when it was set to do it every 15minutes. Now that i disable the HSDPA/HSUPA i see 3G/Edge and email update all the time on the X1i. Just wonder if that might fix it, I'm all kinda still new to all this but i had my X1i for 2 1/2 weeks now.
Hello thanks for all the suggestions, Experiaenjoy, no I haven't tried mainly because I can connect to the data network just fine and get awesome speeds with full bars pretty much everywhere, all of my data related activities and programs work just fine (aka murder my battery life ). I just cant make calls while on 3G.
I talked to a coworker today who used to be a regional manager at AT&T hee said that he saw many cases of people who were having problems where it was due to the SIM card. He said they all had the older orange Cingular card and that an update to the new blue AT&T card solved all problems. So right now I'm trying to see if I can get mine updated (I do have an older Cingular SIM). Once I get that, I will do a hard reset (3rd one also done about 20 soft resets since I 've had it-I've installed a bunch of programs and tweaks) and skip the auto config and go straight to the connection wizard.
I have an unlocked Defy from T-Mobile USA that I'm using with my AT&T service, but I'm only getting EDGE wherever I go, no UMTS at all, and I've even heard of people getting it to run on HSPA bands. I know already that HSPA is available everywhere from my home to my workplace, thanks to my Atrix 4G. I've rooted the Defy and it's running Cyanogenmod 7 latest. Any help would be greatly appreciated, as I can find nothing on this forum or on Google to remedy the issue.
You should try to change the freq via baseband switcher.And restart.
Maybe you got the "2g only" checked in networks settings..uncheck that.
Settings >Wireless & networks > Mobile networks
You can also put automatic(2G and 3G) mode in GSM/UMTS network preferences.
Thanks for the reply Viper. I just noticed the baseband is set to some central Europe nonsense. Should I change it to one of the T-Mobile USA band settings? There's nothing there for AT&T.
Edit: I changed the baseband to US T-Mobile 3.Something, whichever was latest. 2G only was not checked. I'm still getting 2G only. Could it be my APN settings? Could I copy the APNs from my Atrix?
I'm having a problem with my AT&T connection as well, but I've been using my phone unlocked on the network since March with no problem. I'm new to modding, but OCD about streamlining my electronics. My friend suggested rooting my device and flashing a new ROM. I decided on stock Nordic Froyo, and it makes me so happy not to see all the T-mobile crap in my apps tray.
BUT the collateral damage is not so hot. I have no 3g or even 2g connection anymore. I tried the fix in this thread http://forum.xda-developers.com/showthread.php?t=944258 and was able to get a signal with 4 bars instead of the previous state of emergency calls only, but no letters like E or 3g and no ability to use the internet/transfer data. I also installed the broadband switcher in this thread http://forum.xda-developers.com/showthread.php?t=1052745 and tried all of the T-mobile US bands. No luck. I did rest the APN to default. No change. I've been using wifi, but will have to go back to work soon. Not having access to the smart part of my smartphone will feel sort of like having an arm cut off.
I'm not sure what to do next. I could try flashing another ROM, but from what I've read in the forums, that's no guarantee.
If anyone has any suggestions to help a noob, I'd be forever grateful.
Thanks in advance!
Thanks for the link, halah. Do I apply this as an update.zip from recovery? Or install?
Never mind, it won't work for me, for whatever reason.
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?

Did It.. But it seems like it didn't solve my problem..
Hi,
did anyone using Umi Super have any problems with using 4G at 800MHz? Im on giffgaff and even though Umi Super is supposed to work at 4G under 800MHz (thats what the specification states) i cant manage to make it work. I have perfect 4G coverage, 4G sim, 4G tariff, even gave my sim to a friend with S7 edge and it worked on his phone. Maybe new update will fix that? I tried with different sim from different operator (LYCA) and it works but 4G in LYCA is at 2100MHz so I didnt really check the 800. I tried everything and still nothing. Did anyone have similar problem?
I actually bought 2 phones of the same model so I decided to check if 4G worked on the other one and as I put the sim card in I just remembered something and realized same thing happened with my phone. When I put the SIM card in for the first time it DID automatically go to 4G, ok, when I looked for available networks it found O2 4G, granted BUT!!! when i got to "preferred network type" there is only 3G to pick, and THE MOMENT I PICK IT there is not possible to go back. Every network I find from that moment is only 2G or 3G. Now i reckon that a software problem right? See attachments
It is a software bug and I think I sort it out after flashing the phone. For now I sorted out the problem using Networks app by Philipp Mangalov and switching network to LTE/GSM auto
Well it seems the data part of the UMI SUPER is not so super, is it? I face a similar problem but worse. The 4G band of 800 doesn't work(despite being advertized by UMI as supported) but luckily the band of 2100 works without any issues. The problem comes when I'm out of 2100 band coverage and phone must switch to 3G - then I lose all data connectivity completely. So basically whenever I'm out of 4G 2100 coverage(which is often) I am without any connectivity! Anyone facing the same? Solution?

I don't have this issue at all. My UMi Super connects perfectly to my 4g network under 800MHz without an issue here in Uganda. You can install the MTK Engineering app from the play store and check the band compatibility on ur device and you can also set the mode using the same app under android settings.
You could also try updating to the latest OTA which is 20160810 or the one before it by downloading the files from forum post here and saving them to ur phone and updating manually if you don't have the current OTA

same problem
This is indeed a software issue, one I have come accross many times - using an app to toggle between the service types is the best workaround!
There are many apps that work to resolve this, some great ones have already been mentioned.

You need Giff Gaff settings in access point name. If you try and use O2 4g it doesn't work even though Giff Gaff uses O2 network. Settings are really easy to input but MUST be Giff Gaff not O2.

All that's needed is GiffGaff settings inputing manually. Very easy to do. O2 settings that the phone recognises when a GiffGaff sim is used WILL NOT WORK. The Network is O2 but the APN settings for GiffGaff are totally different.
All you guys that think you know what you're doing obviously don't.
No need to Root or use GravityBox or any other App.

Well said. I just shake my head in despair when I see how totally clueless people try to be teachers and Internet gurus with very limited knowledge about the task at hand. These comments should come with warning stickers.
For those who want to be able to switch between 3G/4G and LTE only, use this nifty little APK that I've attached below. It will allow you to enter engineer mode without using the dial code.
Hi
This is a bug implemented in Android 7.0.
I had the same.
1 Just force in your parameters 2G/3G networks
2 wait for network authentification (no more excalamtion mark)
3 go back to 4G
Every thing will be OK to next switch off or plane mode.
Rgds,
LTE band 7 (2600) not working
I recently received my new Umi Super and updated to the last firmware V7.01_20170413, everything works fine except for the 4G. I live in an area where band 7 (2600) is available but the phone can't connect to it. Of course, my preferred network type is set to 4G/3G/2G (auto).
I read a lot about the issue on the internet but I can't find a solution.
I checked the BandMode on the phone by dialing *#*#3646633#*#*, band 7 is included and checked. However, when I tried to remove the other LTE bands and keep only band 7, I got a message explaining that the list can't be empty ("Failed. The band is changed from not null to null, it is illegal"), though the list was not completely empty because band 7 was still selected.
Also, I tried to change the radio band by dialing *#*#4636#*#*, but process com.android.phone stopped working when I pressed "select radio band", even after I cleared cache in phone and sim apps.
Can anyone tell me how to fix the problem and get connected to 4G.
BTW, Network by Philipp Mangelow is not available anymore. Switching between 3G/2G and 4G/3G/2G settings doesn't fix the issue. I tried the giffgaff settings, but the APN gets deleted as soon as I try to save it.
Thanks

The band is changed from not null to null, it is illegal"), though the list was not completely empty because band 7 was still selected.
Also, I tried to change the radio band by dialing *#*#4636#*#*, but process com.android.phone stopped working when I pressed "select radio band", even after I cleared cache in phone and sim apps.
Can anyone tell me how to fix the problem and get connected to 4G.
BTW, Network by Philipp Mangelow is not available anymore. Switching between 3G/2G and 4G/3G/2G settings doesn't fix the issue. I tried the giffgaff settings, but the APN gets deleted as soon as I try to save it.
Thanks

You may try to force 3G and then try to force 4G
You may try to user another IMEI number from a UMI device with 2600 support (of course backup/write down the original one before just in case)
http://www.ucc.co.ug/data/imei/2
After the update to Nougat 7.x how long does it take to do a full recharge?
Do you still have fast charge feature (< 1 hour) or do you lost it like all users reported so far?
What about your GPS? Do you have a fast fix after cleaning history and is it reliable (not losing signal often?).

Is it safe to change the IMEI number? and where can I find another number for a UMI device?
GPS is working fine, it fixes pretty fast, but I'm not sure about interruption in the signal because I haven't used it enough yet
Hi everyone. I have a Leeco Pro 3 X727. I am on Firmware 20s I am having issues to get 4G/LTE signal.
First thing, In my City there is 4G signal, even a couple a days ago I went to my carrier and change my Sim for the newset, just in case.
The last Rom where I had LTE signal IICR was AEX5.4 around May's days. After I changed to CDroid, then to DotsOS... Whatever all I can get its H+ signal. Couple a days ago I change to Carbon Rom 6.1 (Oreos) and the first install, in the configuration I get LTE, but after change to Wifi for finish install all apps, I cant get LTE again. I flashed back Dots, Cdroid and I am now and AEX5.7 and I I have the same issue, just 3G/H+, not LTE or 4G. Also, after flashing firmware 20S I get LTE signal for a While so I think that is not the problem...
I tried almost all APN setting and Nothing. Chang Rom, change Recovery, change Kernel... Nothing just 3g/H+.... My friends with same Carrier have LTE signal...
So, is there anything I can do...? Flash any app, setting?
Help please.

Only use the X7272 5.8.20s firmware - Then you should be able to get it with the correct APN and setting
Don't choose Global, you want the LTE/GSM/UMTS/CDMA setting. If you are still having issues, use the program LTE Discovery or Network Guru.
There are Magsisk
What network are you trying to connect to? What country are you in?
Go to Settings -> Backup & reset -> Network settings reset -> RESET SETTINGS

Nothing. Still "Orange 3G" and conexión icon show H+.
Honestly, I'd say something is wrong with your phone or wrong with your cell towers. The only LTE Band that Orange/Altice supports in DR is B3 (sorta strange that there's only one band, but for a relatively small country I suppose it doesn't matter) and the LEX727 and LEX720 both have band 3, as well as the only GSM(3g)/UMTS(4g) bands that Orange/Altice supports (that being GSM:1800/1900 and UMTS B8 (900GSM)) At first my assumption was that Orange/Altice was a CDMA network, but as far as I can see, there are no CDMA networks in DR!
Edit: download the speedtest app, and see if you're getting the same speeds as a phone that shows it's connected to LTE. If you are, there's no issue besides the phone reporting the connection wrong. If you're slower, though...

Maybe the problem is Orange Altice. The 4G coverage its very new in my city. I al ready tested speed and its 3G 5mb/3mb
Thanks for answering!

Oh! I think I know the issue! When I looked at Orange's website (trying to find network specs, which strangely for a network that supports BYOD, they don't have listed, or at least I couldn't find it) I saw that they have subscribers pay for data, as is standard practice in the US (where I live). But the thing that caught my eye is that you also pay for speed.
So... Let me take a guess here. You pay either RD$1499 Or RD$1349 for their 5mbps unlimited plan?
Basically, my assumption is that if you're paying for one of their lower speed tiers, they put you on a 4g or 3g network to save LTE bandwidth for the people who pay more than you.
Tell me if any of this sounds familiar... I feel like I may've found your problem!

Mmmmm suspect ... actually I have an even lower plan, RD $ 580 (USD$12) and I only use the data when I buy additional packages ... Most times I use Wi-Fi and just use Data when I am not at home/job and the 3G its veeeery looooow speed... Thank bro, that could be the problem.
