HELP????? i cant seem to get my phone working on gsm?

Dear friends
i have a unlocked HTC 8525 !! i am in brazil and can't get the sim card here working with my phone. i can see the sim menu and everything but the phone only says no service . i try'd to change the network under phone/menu/option
but i couldn't get it working , and the closest suppor for HTC is in Sao Paulo and im 600 miles away
Help me please

Hi DJFuscao,
I have an HTC Tytn that I regularly use in Brazil (Sao Paulo) since oct 2006.
I´m not sure if I will be really able to help you, but I´ll try to give you at least some information about my experience.
I believe that sometimes autodetect network does not work properly. You may try to change these settings:
- Settings-->(Personal Tab)-->Phone-->(Band tab)--> Select your Network type: change this to GSM
- Settings-->(Personal Tab)-->Phone-->(Band tab)--> Select your GSM/UMTS band: GSM(900+1800)+UMTS(2100)
I have also experienced some problems some months ago when VIVO activated their GSM network. It simply stopped working, kept searching but did not find TIM´s network.
What I have done then:
- I have changed from Automatic Network Selection to Manual (you will find this option on "Settings-->(Personal Tab)-->Phone-->(Network tab)--> Network Selection".
- then I tried to click on Find Network on the same screen
- I chose TIM from the list
It has not worked at the first atempt because there were some different options for TIM on the list but it has eventually worked.
Another thing I would check is if it works with any other GSM carrier from Brazil. If you can borrow a SIM from some friend this could also give you some clue.
You may also find some specific information about HTC 8525 phones in Brazil on the link below:

[Q] Imagio on TMobile

Has anyone been able to get the Imagio to work on any other carrier other than Verizon? I just bought one that is unlocked put my SIM in it but it still wants to dial Verizon, instead of T Mobile. What do I need to do to get it to use T Mobile as a carrier?

Have you changed the phone mode to GSM only?
Send key >> Menu >> Options >> Network -- select "GSM/UMTS only"
See if it works then.

[Q] Manual operator selection on RAZR M (unlocked for GSM)

Really strange case:
I got a RAZR M that I hacked to work with US GSM carriers using this method: http://forum.xda-developers.com/showthread.php?t=2166542
I am using my corporate ATnT card with it.
I am currently in roaming (Russia first, now Kazakhstan). Only GSM/UMTS networks here.
I have another simcard with me which is from Russian operator (Beeline). This network is present in Kazakhstan, however simcard is Russian, so in Kazakhstan this Beeline simcard is also in roaming.
Status:
On ATnT card, my RAZR wont connect properly to local cellphone networks. To explain better - it will occasionally connect to one of local operators (KCELL, MCC/MNC 40102), but it takes A LONG time to connect, easily disconnects, and it is very unreliable and erratic.
Moreover, in Mobile Network Settings menu there is NO OPTION to select operator (i do have GSM/UMTS mode enabled, not global).
On BeeLine card, my RAZR happily connects to any of chosen networks, AND operator selection option is available in Mobile Network settings.
I have another phone in my pocket - old Nokia S40 based. This one works perfectly with Beeline simcard. With ATnT simcard it wont automatically connect to a network, but manual operator selection dialog is accessible, and I can select any network and connect to it.
So, for some reason, with ATnT simcard in my RAZR, mobile networks settings menu disbles (completely removes!) operator selection dialog.
Any way to get around this? I have scraped around every possible search criteria, but I cant find any way to force that menu item to appear!
However, I accidentally stumbled upon a weird workaround:
I put Beeline card in
Manually select operator (Beeline)
Turn off the phone
Put in ATnT simcard
Turn the phone on
In this case on startup phone throws in notification (from motorola phone app) saying "selected preferred network not available".
If i click that notification, it takes me directly to network scanning menu, happily displays available networks and allows me to connect. From that point on, it stays fixed to the network I chose.
This means that this is not a problem of simcard or radio or ROM directly. It is some weird trigger built into ROM that reacts to ATnT simcard and removes "operator selection" option from setting.
Any idea how to force Operator Selection option to appear, or invoke it otherwise? Or maybe solve the issue alltogether? My workaround is really inconvenient.

[Q] HELP,Won't Register on GSM networks

hello i bought one galaxy note 3 (my second one)
i'm having one issue,the first one i bought and i ended up selling had a Bad esn but let me to conect to other networks
such as telcel on mexico,movistar,iusacell and other ones
i bought another one but i don't know why i can't use it on other networks
i tried with the service mode codes but i can't enter to something like the UMTS option on the s4 to turn off the perso sha 256
also i tried installing again the firmware with odin and it continues without signal
when it starts it shows some "sim icon" notification on the status bar and says "phone activation" the sim card is from an unknow source
it 's didn't surprise since i know the verizon phones come GSM unlocked.
maybe if someone knows other form to flash the firmware could help.
i read about some galaxy devices loosing the imei after one update ,if i dial *#06# it shows my device .
if i go to settings and mobile networks and try to select the network(telcel) i won't let me register on the network.
i hope everyone have a nice day and maybe someone could help me.

Access to SIM toolkit or SIM settings?

Hi all
I'm running Pure Nexus with an Israeli provider (Golan) that provides free roaming + data in many countries.
Phone works perfectly in Israel and the US, but has problems in Europe.
On any other phone, I can solve these problems by enabling roaming in SIM toolkit.
The 6p doesn't have SIM toolkit (it has it in the system apps, but you can't open it).
Nothing I do adds SIM toolkit to the avaialble apps.
Other android phones have SIM and Network settings where you can change the settings, but the 6p doesn't (also tried reverting back to stock).
I can't register on ANY network outside of Israel / US, although once in a while it will work (it worked in Germany, but didn't work in Holland and Turkey, go figure...).
I can't downgrade at all to 3g / 2g (it won't even find any cellular networks). When trying to connect manually to networks it will immediately show me a "network unavailable" alert.
I really love this phone, but this issue is driving me nuts, as I travel quite often..
Any help appreciated

Is your device the International model (H1512)? Did you enable data roaming under System>>More>>Cellular Networks ? Lastly, dial " *#*#4636#*#* " and see if there are any toggles under Phone Info that will help you.
