Can’t change network and roam with Att tilt

Hi,
I have an Att tilt (stock) and at work I loose phone signal.
I had a similar issue with my sprint phone and phone service. When the setting for “roaming or sprint network” was set to “automatic” I would loose signal all the time. Instead for the phone locking into the roaming stronger signal (Alltel) would try to lock into the sprint weak signal all day (going in and out resulting in lost calls). When I had that setting to “roaming only” it would lock into alltell (the stronger signal) with 5 bars.
On the tilt when I go to phone/settings/network the only option is “find network” and that option looks for att and not anything else. Is there a way to force my att tilt to roam only and therefore lock to the alltel network (very strong signal)? Or expose all the available networks and choose which one I want to lock in?
Thanks for all the help, this is a great forum

cannot locate different networks
im having the same problem. phone has bad at&t signal. I cannot locate a diferent network.

Forcing roaming with tilt
I guess the question is…Is there a way to force roaming only in a stock att tilt?
Thanks,

Bump
Anyone?
Thanks for the help

Bump again....I want to know the same thing. I have free roaming, but I can't get it to roam.

PRL file
Bump
Does the phrase “PRL file” provide any help?
Is this an editable file that can solve the issue?
Thanks

I'd like manual n etwork selection as well, but you may be roaming and not know it. AT&T sets up all their phones so it looks like you are on your native network, even when you're not. I had bypassed this and enabled manual network search on all my Motorola phones, I'd like to do the same here with my Tilt.

i suggest setting the band in settings/phone to wcdma. Try it.

I don't have that setting. AT&T removed it. In 3G mode the field test doesn't do much. In GSM mode it seems to work well.

The stock HTC ROM allows this, but it didn't seem to do anything. I know because the ATT HSDPA network is available at my house (barely), and when I lose it it switches to a full signal Edge.
But! If I switch to GSM it seems to lock to the much better Edge signal at my house instead of the HSDPA. That works for me, but will it limit my signal elsewhere?

I had the same problem....the network found was AT&T all the time and no signal, so I place the Sim in a friends Nokia with manual network selection and choose T-MOBILE, place it back in my tilt...problem solved !!
Note: I'm an international user, only use roaming when in USA. But this may help you guys !

Desperatly need help getting 3G instead of E

Hi guys,
I brought my first xperia from my phone serivce provider, and it always had the "3g" symbol at the top. However, when my xperia broke, I had to buy another one and got one of ebay. Since I brought the new one, my phone always has the 3 on top. I'm currently using the firestorm valkyrie rom which as the htc interface. When I go to the data connections it says an option (3g) "change to gsm mode" and on is selected. Even when I toggle that, it still always has the E symbol. What do I need to do? I know my sim card is cabable of getting the 3g. But this is a real pain because every now and then my phone just doesnt receive service, so I constantly go onto the comm manager and then it seems to just click that there's service and shows 2-3 bars. Then all of a sudden again after a while there'll be no service. So I'm guessing that's because of the E thing. It shouldn't be my current location as I've never experienced this before.
Is there a setting I can go to to get the 3g symbol? Or a patch I might need for the phone?
Please help
Kindest regards.

You need to change while the connection is not active, I believe. Or... you got the Xperia version incompatible with your network... Or... the ROM is buggy, try another.

sorry, I need to change specificially what when the connection is not active? Say you mean, turn off my phone settings and not connect to the network and then adjust something? It is not the rom. and the seller on ebay has stated that it is a 3g phone - many others have brought it as well with no complaints.

3G settings on x1
Hi
For some reason your phone is only camping on the GSM network (G or E indication depending if your carrier provide GPRS or EDGE on the GSM) instead of the 3G network (which you have been using before).
In settings, communications you should be able to set "3G change to automode" to on,
When this is set your network provider will tell your phone to use the 3G as preffered network, but when coverage is not good enough it will drop you back to 2G (which has a better reach due to lower frequency band).
If it does not happen automatically there might be another setting that is wrong,
goto settings, all settings, personal (tab), Phone.. then choose the "band" tab (need to go to the left with the arrows) , then you have the dropdwn lists to set:
select you network type (need to set auto or wcdma to get 3G)
select your GSM/UMTS band (need to set 900+1800 for europe, 1900+850 for us, dont know who is using 2100+800)
once changed the phone will restart the phone part and search for your carrier in the right band.
good luck

Hi,
Thanks for your reply. I had changed the automode to on. But still had the E.
I went to the setings, and band tab, and i had selected:
Select your network type:
(blank)
Select your GSM/UMTS band:
Auto.
I changed the first oen to auto, and as for the last, here in Australia I'm with Tesltra which is 850 UMTS? I think I read online. Anyway it didn't have the option in there, so I went through them all but wouldnt get service at all except for the first: GSM (900+1800)+UMTS(2100+900). and Auto. I think my last experia might have had auto for all of those too. Anyway with those only two options working, I still get the E icon. Even tried setting aeroplane mode on and then off to see if it might register, but it didn't.

I see , Telstra is one of very few networks that use 850 for WCDMA so they might be using a different RADIO ROM than the rest of us
I saw in the thread below that there is a TELSTRA AUSTRALIA (1.03.841.8) R2AA008 version..
http://forum.xda-developers.com/showthread.php?t=477801&highlight=telstra
you probably need to flash that one to get the 3G working on telstra..
3 is using the normal 2100 so you could also try with their SIM just to check that there is nothing wrong with your hardware..

Sorry for the late reply.
I have realised that i'm in an area that doesn't support 3g. however my last xperia phone which I brought from telstra was the x1a, which had the next g network - hence I got the 3g symbol. However I have found that that I have the x1i, which doesn't list that network. I rang up telstra, and they transferred me to the sony erricson call centre, and they said you can try and do an update but it is not gaurenteed to get the next g service. I have already flashed a htc rom and don't particluarly want to change it back, unless i'm certain that I will get the next g service.
With the rom you have provided, do you think it will have the UMTS 850 band on there, and my x1i would be able to connect to it? I would have thought that it would be a hardware preference, not a software. In which case, even if I updated the rom because there is say no "chip" that allows for connecting to that band, it wont connec to it even though I may have selected the 850 UMTS band.
Sorry if that seems all over the place, but yeah... I'm not sure.

[Q] HELP UK model with serious signal issues on ATT in the USA

Hi all, well my One arrived from the UK today.. As I feared it does not have the ATT LTE bands that PDAbd.net suggested it had, bummer, but I can live with HSDPA... Set up the phone, it asks me to select the operator I am unsing, with ATT as the first choice... all goes well.. I load it up and initial impressions... WOW.. what a great phone.
BUT and and very BIG BUT.... the signal is terrible... bouncing from no signal to 2 bars and displaying H one minute, 3G the next and then E...
Driving down a notorious road it drops the call at least half a mile before typical and doesn't pick it up again until even later..
Does anyone know if there are any setting I can adjust to optimize to ATT?
I really do not want to put it is back in the box, but unless someone has a suggestion for me, I have no choice...
Help!!
Many thanks,
Nick

A quick question. Where did you get your HTC One? And have you used any other HTC Phones before and got good signal with it?

Hi There,
I bought it in the UK. It was a legitimate HTC supplier and an unlocked model 801n.
I have used a couple HTC phones in the past:
ATT 8X - worked well (at least as far as signal was concerned, but that was the ATT model)
I also had a Verizon Incredible, but since that is a different provider, I am ignoring it.
Other phones I have right now adn tested in the same location with the same SIM:
1. ATT - Galaxy note 2 - good signal no issues
2. ATT LG Optimus G - Good signal no issues
3. ATT Iphone 5 Good signal no issues
4. ATT Nokia 920 - good signal no issues
5. Blackberry Z10 - unbelievably good signal - no issues - Unlocked ATT bands, not ATT branded (Purchased from Expansys USA)
This is why I am wondering whether it is some kind of optimization issue. I cannot believe HTC could have made such a mistake in design. Also, if I switch to GSM only, I have full bars.... It is only on 3G and HSDPA that the signal is poor and the display oscillates between 3G and H
Any advice?
Many thanks,
Nick

Are you rooted? The solution is disabling fast dormancy on HTC One. New HTC devices enables fast dormancy by default which affects & weakens signal strength on networks that doesn't support it yet. If not I am not aware of any ways to disable it without root yet. I'll update you if I find one.
On UK almost all networks do support fast dormancy already except for Three UK so that maybe the reason why it's enabled by default in the US however I am not aware of the implementation of network carriers there sorry.

No I am not rooted - what will I lose if I root it? Do you know of a link to a simple thread with rooting instructions and how to disable the fast dormancy? I am not super experienced with Android yet
Does anyone know whether ATT supports fast dormancy of not?
Also, I have been led to believe that the One supports a number of carrier frequencies, but they only enable those for the specific region it is sold in. Do you know if there is a way to enable the other frequencies? Or is this just an unfounded rumor? Also, do you know if there is a way to check which LTE band the phone I have is equipped with - Not an on-line reference, but a way to find it on the phone?
Many thanks!!

Your warranty if you mess something in the software's side like bricking your phone & OTA updates. But you'll be able to update anyways just by directly flashing on the phone.
Anyways here's a noob proof app to rooting. Please do some research first before going so you'll not mess this up.

Check this regarding what is Fast Dormancy and tell us if it works(probably NOT (it works only to samsung phones) but it is easy to try) http://androidforums.com/samsung-galaxy-s2-international/674208-fast-dormancy-in-nutshell.html
"To turn FD on/off enter *#9900# in the dialler to get into the SysDump screen then select the Fast Dormancy option"

You mind sharing the link if they have stock? Good luck with the signal issue.

I had a friend with an international GS2 with the same problem. Constantly bounced from HSPA+ to 3G to EDGE to no signal. I'm 99% sure that the issue is network settings, you likely need to check SIM card, data plan provisioning, APNs, etc.

Hey, thanks - Do you know what settings I should use? I have an LTE provisioned SIM card...I assume that should be ok, since the phone is LTE enabled, just wrong bands? I have tried with Auto LTE on and of - I currently have it on GSM/WCDMA - it has been working better the past day, but it is still not right..
The SIM works perfectly in the Note 2, Optimus G etc. So I am wondering whether I need to look at the APN or something like that, but I do not know what the best settings should be. Anyone have this info?
Many thanks,
Nick

APN shouldn't affect your mobile signal reception. It's just made for cellular data profiling. So you are able to connect to the internet.
How about try setting your network selection mode to manual and just select the top most usable network there?

Interesting... I am in Korea right now and have great signal... no issues at all. However, my data indicator is still bouncing between H and 3G, so that is very strange...
Despite the indicated low signal and bouncing data connection type indicator, the phone is working well, have not dropped a call recently and excellent phone call quality...
NO LTE connection in Korea though.. I assume that is probably due to ATT not having a LTE roaming data service agreement here? I believe my phone has at least one LTE band that it supported here.
Have fun..

I think u should talk to att people may be they can help? With the signal issue or the data connection issues!

I can't really help you but as far as I know LTE is already unlocked and working on all international S4 Actives. Mine certainly worked perfectly out of the box - although I turned it off promptly because I have ****ty 4G coverage where I live so it was nothing but a battery drain for me.
Are you sure you have a 4G sim card, and that you are in an area where 4G has coverage?
If you go in under settings > connections > more networks > mobile networks > network mode don't you have the LTE option at the top?

Well then I really have no idea - the only thing I can think of is that you might need to replace your sim card if your provider didn't already do so in advance of the 4G rollout. Hopefully someone with more information might step in here, but the international version is LTE capable out of the box. If you don't hear anything else I'd suggest to try and contact vodafone and get a clear answer from them first.

If you check the mobile networks in your area and don't see anything that supports LTE, you may just live in an area that doesn't have it yet (people get 4G and LTE somewhat mixed up - 4G is the overall identifier for a whole class of technologies with "4th generation cellular networks" basically while LTE is technically one of those technologies so, it should rightfully be classified as 4G in most respects.
Having said that, the only way I got my GS4A to function in LTE mode - meaning it actually shows LTE in the notification bar under the 4 with a small G and LTE underneath it - was to go into the service menu (*#*#4636#*#*) and change the preferred network type to either LTE only or LTE/GSM auto (PRL). Once I did that the radio would reset and connect and then it would be in proper LTE mode. Doing a speedtest with the Speedtest.net app shows LTE as the connection whereas with my standard setting which is WCDMA Preferred (T-Mobile AWS) it'll just show as "4G."
I've had no luck making alterations in the Settings/Mobile Networks section, I have to change it in the service menu to get LTE functional. I don't use it because here in Vegas where I live (specifically my home location) the LTE mode gets me about 1-2 bars of signal (about 8-12Mbps) whereas the WCDMA Preferred setting pulls in 5 bars rock solid and 25-35Mbps.
Can't do screenshots or I'd add them, I'm running the pre-release MI2 ROM presently and that aspect is borked.

That would be because you're on the i537 from ATT, rather than the i9295 that this discussion is about. I checked google and vodafone holland does indeed use LTE on the right bands in its brand new rollout, so it isn't that - most likely it's his sim that needs replacing or it's just not activated on his account yet.

How to force 4g LTE on sim 1 or sim 2 as needed?

I am using the dual sim Exynos version of Note 9 and want to be able to force 4g LTE on either of the two sims as needed.
Can someone please advise how to do this on an unrooted phone? Thanks

Anyone?
I also found no solution. I think it's possible without root but no one is updating the Phone Information Apps. We need to get access at phone information 2 and not only on 1

Mine are both 4G / LTE. Inever need to switch the Sims around. Whichever I choose for days gets LTE. this is different from what I had in the Note 8. I was pleasantly surprised. Therefore it may be a settings issue for you. I have the Note 960F/D

you may try quickshortcutmaker app on exynis version and follow instructions in video
https://youtu.be/AdGAB4qRvYA

I feel like the Tasker App could handle this easily.

I dont understand the actual need.
Simply changing preferred network mode from LTE to 3G shall do to stop LTE on any sim.
I use LTE on both sims for calls
I use LTE for data on specific sim by making it as preferred sim for data.
Settings -- Networks -- Sim card manager shall help in these settings.
I am on exynos N960F Indian firmware.

You don't understand the actual need ??
So i will tell you
On my work i am located in a big Hall underground. The Provider i need down there is only coming in with -110 dB and less which is one LTE Bar. If i leave Automatic Mode it switches always in 2g Mode because of much higher Signal. So to get a nice experience and have LTE always available there is no other solution. The same kind of problem is on my other LTE Sim when on different Locations during the Day ! So i have no time to always switch sim cards so that sim2 is forcing lte !
And off course no one else knows this and so i benefit of this extremely fast connection where all others are crying because of no 4g connection

OK understood.
Did not you get one UI already which has option of LTE only selection too for network mode.

Negative. Here the German Rom (dbt csc unbranded)
Has never got LTE Only mode in the menu. This is also for all European Roms. I have had this only when using Root and Custom Roms.
Because i use many banking and streaming apps it's not possible to root this time. Even with Magisk Hide they will not work.
If i could i would have rooted long time ago. This is getting me Crazy really

Sorry but are you reading my Post?
I am talking LTE Only on Sim Slot 2 of any Samsung Phone out today. All the LTE Only Apps or the Phone Info Menu where they lead you is only working on Sim Slot 1.
I am sure there is a dial code like the one it gets you to the Phone1 Information Screen where you can change the bands. But only for Sim 2 (Phone info 2) on Samsung.
So again LTE Only on sim Slot 2 on Samsung Duos Versions is not Possible @ the moment without Root!
If there is any Dev out there you would be the first One to create an app where Phone INFO 2 is possible to change! Or just find the right hidden code for that i know it's there like the Phone Information 1

Hi,
There's an option to force the selected APN to LTE only but I don't know if it will behave like you want to.
What's great is that it's per SIM so you can try any combinaisons.
Deselect "undefined" and select only the "LTE" one (screenshots).
I expect that if it find any other bands getting a better signal than LTE, it will just let the phone loss the signal and not trying to catch the LTE one, but you can try.

There's an option to force the selected APN to LTE only but I don't know if it will behave like you want to.
What's great is that it's per SIM so you can try any combinaisons.
Deselect "undefined" and select only the "LTE" one (screenshots).
I expect that if it find any other bands getting a better signal than LTE, it will just let the phone loss the signal and not trying to catch the LTE one, but you can try.

Hey thanks for that. I really was in hope this could work but that would have bean to easy. Unfortunately it's not changing bands after deselecting undefined and than choose some network mode it remains to the same band but it looses the mobile data symbol (but still remains in same band).

This code and all Codes are not working on European Samsung Devices with Android 9 .
I Even Rooted my Galaxy Note 9 and all the hidden codes are Not working ! Even Samsung Phone Info App or other Apps are not working with Latest Android 9.
Only way is Root and Custom Rom like Alex Dev Rom where the CSC is Modified. There it was possible to change both Sim to LTE Only ! But as told before with Root
i loose to many services which are detected even with Magisk . So my next Phone will not be Samsung anymore because of that.
