Problem with automatic gsm nework settings

Hi to all,
i live on the border between switzerland and france, which means that if i don't control roaming i am dead!
on the QTEK 9100 (rom 2.8.7.1) i can set my preferred networks (SET NETWORKS) in automatic mode, but every time i soft reset this information is lost. does the same happen to you? do you understand why?

yes often happens to me and dont know why. these settings should be stored with the network provider not on the handset so maybe its a network problem!?

As far as I know they should be stored on the SIM. There is a problem with some devices either ignoring the preferred networks list entirely, or loosing the settings (as they are SIM-locked by the provider so the saving to SIm fails silently).
Check with your SIM/Network provider - they will be able to tell you if you can change the settings or not. On some networks, and with some SIMS you just can't.

Disable Data Connection?- Think I've done it!!

Hey there folks.
I'm going away to australia tomorrow and don't want to pay £7.50 a mb!
I think I have managed to disable the data connection by going into the settings:
Menu> Settings> Wireless Controls> Mobile Networks> Access Point names
And then geting rid of all except the T-mobile UK settings and then renaming the APN to general.t-mobile.uks (just added an "s").
The little data arrows have dissapeared from the top of the screen and nothing internet based is working but I can still send MMS and connect to and use wifi!!
Anyone else want to try this and confirm that it does actually totally disable the data connection?
Thanks

its very easy, change the name of you APN server, if you do it the phone can't stablish a data connection and force the data connection to 3G.
The phone dont use more the 2g or 3g.
If you want to do it better maybe you need to configure any iptables for deny connections or something

I agree. Easiest way to be to change the APN so it can't be used.

Not sure to what extent this would apply to you as you're apparently from the UK, but this is not good news for traveling abroad w/the G1, at least if you're from the states :/

It's been tested and proven that disabling the APN (e..g by misconfiguring it as the 2nd poster has mentioned) would prevent any data consumption, period. If you have an understanding of how telco network systems work, you would understand as well that this is not specific to any telecoms service provider -- if the data APN is incorrect, it simply cannot authenticate against the home data network, and hence data would not work. If roaming, incorrect login credentials would prevent the SIM from logging onto the roaming partner's data network and thus data service is unavailable.

if you download droidsan tweak lite, you can try to activate various apns until you see no 3g or 2g icon then you know you aren't receiving data
let me know how it goes!

Could very well be; I'm not versed in wireless tech enough to argue one way or the other. Someone in that thread specifically said changing the APN did not work for them however. Whether that's because they did it incorrectly or something else entirely, I have no idea.
From the thread I linked to:
by patuf4e
Actually I tried to change my APN settings to something incorrect. However, the phone keeps connecting to internet, apprently using some internally stored configuration by the time I initially synchronized with my google account. Is anybody experiencing the same?

[Q] unlocked/Europe: cannot send/receive MMS

Hi,
I bought a Droid Pro in the US, unlocked it and I am now using it in Switzerland with my local Swisscom GSM SIM.
I can't send nor receive MMS.
I have setup APNs correctly for internet (works) and for mms. When I look at the message details on the MMS I try to send, I see "Cause code: National access coverage not available". I have tried with Handcent and ChompSMS, but still doesn't work as I guess they rely on native messaging app to send MMS. Unfortunately CompSMS doesn't support sending MMS through their network.
Any ideas on this could be fixed? Any workaround?
Thanks
Happy Holidays
Fred

Make sure you entered the settings exactly and try again. If you are using a GSM or HSPA network you should disable global mode and put the phone into GSM/UMTS mode only.

@Class: thank you for your response. I confirm the Network Mode is set to GSM/UMTS and that the APN parameters are correct for Swisscom.
What is interesting is that in settings->About Phone->Status->My phone number I see the US phone number that I got when the phone was activated with a Verizon prepaid plan.
Anybody is able to send/receive MMS on GSM, with or without prior US activation on Verizon?
Thanks

I also bought from the US and activated, and unlocked in Kuwait on a Kuwaiti SIM card. I confirm not having any data connection whatsoever! I've defined the APN settings correctly (works on a Samsung Spica & A Motorola Defy) with no luck.
Could you please check for me (*#*#4636#*#* --> Phone Info --> Menu --> Select radio band) what are the radio bands available for you to choose from?

I'm also on Swisscom and my MMS doesn't work either.
Did you set up two APN's, one for GPRS and one for MMS?
What happens if you send a MMS to yourself? I just get the SMS from Swisscom, that i received a MMS and i should look it up in the internet.

@rafeee2: I also see "USA Band", but if I click on it I loose connectivity to Swisscom and have to do factory reset to re-connect...
@ThiloH: I can't even send MMS. I get "National access coverage not available", both before and after factory reset. I tried factory reset as I thought the MMS problem could be related to the fact that my phone was initially activated on Verizon.

I heard on another forum that flashing with the newly released SBF solved the issue to one guy. If I flash, will I need to re-activate via Verizon?

My understanding is that you don't need to re-activate unless you want to use the phone in the US with Verizon/CDMA. I can still use my unlocked phone on GSM with my Swisscom SIM after a factory reset. I guess that flashing with the new SBF will have the same effect.

i can confirm that, i flashed yesterday with the SBF-File and the Verizon-Activation showed up, but i could skip it and it worked after it.

OK so I SBFd yesterday. Is it normal to have all you contacts, apps & widgets intact afterwards? The only thing that changed was that the network mode changes from GSM/UMTS to Global, and still no data.

As far as i know, the data you have on the SD-Card doesn't get removed when flashing.

You've already SBFed, what did you find after the phone restarted? What I'm saying is that EVERYTHING was intact, as if nothing has happened at ALL.

I did a factory reset before SBF, but after it it was like fresh out of the box.

Hmmm.. So we're still stuck here then. I think that unless the "select radio" menu shows other bands, we won't get data.

mmmmh. I also have only "USA Band" listed in there but when I click it stops working here in Europe and I need to factory reset. So I guess the hardware capabilities of the phone are different from what you can select in this test application.
What do you see in the "GSM disconnects" section of *#*#4636#*#* --> Phone Info ?

It's always DcActivatingState this or DcActivatingState that, and after some time it turns into:
DcInactiveState disconnected with last try at XX:XX fail because Unknown Data Error
What's an unknown data error supposed to be!

I just got my Droid Pro and can receive MMSes here in Australia, but can't send. I get either the National access coverage not available or service not activated messages.
It happens on both Telstra and Virgin. I can receive MMSes on both networks, just can't send.
I tried sending a short text message as an MMS and that won't go through either, so it isn't a size problem. Flight mode on/off doesn't help, and the phone is already in UMTS mode only with wifi off.
Has anyone found a solution?

[Q] unlocked tmobile hd2 no data connection??? please help

i have a tmobile hd2 and its carrier unlocked i am using it with ATT and i just recently lost all data connection to my phone. i have an unlimited data plan that was working perfect until just recently. no internet or mms not even weather!! only can use wifi. can anyone help? thanks

Have you tried
*#*#4636#*#*
dial this and then go to phone information.
Have you run the ping test?
Checked what Current Network says?
Checked to see if there is anything listed under =======DATA======= ?
Have you tried to put a friend's TMO sim in the phone to see if data is restored?
All the data you can provide could help solve your problem. As is, the problem might be a little ill defined.

If you are running Windows Mobile on your HD2 from the home screen touch onvStart Menu/Settings/Menu/All Settings/Connections/Connections. Then tiuch on the adcanced tab and then touch on Select Networks and make sure AT&T is the selected network. Also tiuch on the Task tab and select Manage Existing Connections. While on the Modem tab make sure AT&T is selected and under the Proxy Settings make sure the box beside "This network connects to the internet" is checked.
Ok if you are running Androud then go to Settings/Wirless & Networks make sure allow data connections box is checked. Also go to Networks/Vertualy private networks (VPN) and make sure your AT&T VPN is corrwct.

i have fixed the problem! i was running the tmobile 3.14 rom udate which sucked and i just flashed an energy rom and alll is working again thanks for the suggestions

Same Problem
Someone please help and know that I know little to nothing of technical terms! I have the same problem. I have a T-mobile Hd2 and had Android put on it. Right at first I had a data connection then all of a sudden-NO DATA. I'm so frustrated! I checked the setting for using the phone as data connection SEVERAL time. I can get wifi but no data otherwise. PLEASE HELP

Try:
Menu - Settings - Wireless and networks - Mobile network - Access Point Names - menu button - restore to defaults, and follow the simple instructions
This should place the latest APN from your carrier on to the phone - may need a soft reboot

Hi, I'm currently trying to get my T-Mobile HD2 to work properly on NTT docomo, a Japanese cell carrier. I moved here at the end of May and have been using a data-only SIM through bmobile, a provider that uses the same towers as NTT docomo and it worked perfectly, however I switched to a voice and data plan and now I have no data connection. Voice works fine though.
I followed nenol's steps and under =======DATA======= it says, "State: DcInactiveState disconnected with last try at 9:49PM fail because Activation Reject GGSN" What now? Ha

How can i force the OnePlus 6T to an specific network?

Okay, so I am on Verizon and I purchased the OnePlus 6T straight from OnePlus website. I have the 8gb ram and 256gb storage model. I have unlocked the bootloader but haven't installed a custom recovery or rooted yet. Just wanted to unlocked bootloader since it requires a wipe of device storage in case for the future.
Anyways, the phone works amassing, battery life is great, I had a pixel XL before this, screen is fantastic and is plenty fast but I have ran into an issue. The phone was activated on Verizon using Sim 1. Signal is not an issue, always have LTE from Verizon and way better signal than pixel XL ever had.
My issue is I live in a border town with Mexico and I just noticed that when I am close to the border, like within a mile the phone switches to Movistar cell provider. Movistar is a Mexican cell phone provider. Is not that I lost signal because my pixel XL had signal all over there before and the OnePlus 6T is stronger, is just that apparently the Movistar provider has a stronger signal on that area and the phone is choosing to pick up the stronger signal, even if it means going off and switching to roaming.
It doesn't cost me any $$ and speed is wicked fast while roaming but Verizon will only allow 0.5gb of roaming per day which limits the usability of the phone. Anyways, thanks for reading my long post, just wanted to give some context to the question and hopefully find an answer. Like i said, I did search and didn't find anything. If I have to root to install an add-on or an app that lets me pick my signal please advise. Also I know that I still have a strong Verizon signal because I used ltediscovery app to check and it shows the signal strength of whatever many signal phone is picking up.
Thanks in advance for reading and for answers.

One option might be Network Signal Guru in the Play Store (requires root). It's the only app I've found that allows the user to lock the phone to a specific band - which might help with your situation.

Outstanding sir. Thanks for the information. I guess time to root then for me. Been waiting for a stable recovery for OnePlus 6T but I supposed no harm so far using current version of twrp, as far as I have read.

have you tried going to settings, internet, sim, sim1, network provider, disabling the automatic option and selecting your preferred provider manually? this way you will stick to that selection

Either I do not have that option or I couldn't follow the steps.
When I go to settings, wifi & internet, Sim, sim1 then I see what is on the attached screenshot.

it seems you are missing some options
it should look like this: network operator
try to search for operator or network on the main options screen at the search bar on top.
if still no luck than maybe there is something wrong with your sim card or apn settings. you should try to contact OnePlus support than.

Mine does have network operator anywhere.
I look through all the settings and nowhere to be found. I am on Verizon network and only sim1 has a card in it.
Sim2 is empty.
I can get to the special settings through *#*#4636#*#* and even there changing different LTE settings keeps reconnecting to roaming network since the tower is like a stone through away.
Any other options would be greatly appreciated. Also the app that was suggested in 2nd post, rooted phone to try it and that option if it works is behind pay part and that app fee is $50/m. A bit steep for me so looking for options still.
Thanks in advance

Couldn't you just disable roaming?

I could but I only have an option for disabling data roaming, not roaming all together. I tried it in the past and all it did was kept me connected to the roaming network and turned off the data off of the roaming network connection. Meaning I had zero data connectivity.
I wonder if putting a Sim in sim2 slot would open up more settings ?
If anyone is using 6T on Verizon could you please go to wifi & network, sim1 and see if you get any more options than what I posted on previous ss about 3 post ago.
Thanks in advance

do you have a carrier locked device? that might prevent you from doing changes to your sim.

I don't believe this is carrier locked since I bought straight from OnePlus website. Hell, I was even charge a currency conversion fee by my credit card cause the purchased was in foreign currency.

you should try another sim (family or friends) and check if the missing option appears. maybe try your sim in another phone too.
lastly you could try a full factory reset (deletes all data)
at the end if it still does not work you really should call OnePlus for help.
also I found this app here: https://play.google.com/store/apps/details?id=com.pomo.android.networkoperators
open it and select "available networks"
that should open the missing menu to toggle operator selection...
