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:

Hi there.
I have a friend who has an X1. He is reporting that the X1 is working with his O2 sim card and working on Vodafone however it isnt working with his Latvian sim card (in the UK) (i.e. Tele2 and LMT). Are there any settings you need to change in order to enable roaming? Is it possible for a phone to be country-locked?
Thanks,
Lawrence
It might be the phone is locked..then again it might not be.
What does he see when he puts in the card? How long do you wait while it searches for a signal? (Sometimes when I'm roaming it takes a few moments -in egypt I think I waited 2 minutes - it might take longer for Latvia to register for one or other reason).
thanks for your quick reply!
I dont think it is locked because it works on both O2 and Vodafone fine. I bought the phone from vodafone and all of their phones come unlocked.
its more likely that the phone isnt using the correct setting for the service provider... usually when the phone detect a new sim it will ask you if you want to change your settings... your friend may have missed it and didnt change the setting so it didnt work
Roaming is enabled by the origin network, not by the phone.
There is a chance that some of the UK networks don't allow those SIMs to roam on their network, but you would need all 4 for them not to work.
another reason could be too old incompatible sim card
people have from time to time reported rather old sim cards being
incompatible and solved it by getting newer sim card from their operator
Hello friends...
I am from SPAIN, and I just switched mobile company from good-old VODAFONE, which for some reason have been losing coverage where I live, and now I am on this new company called "SIMYO" who´s service is simply great, with awesome coverage troughout Spain (uses Orange Antennas and repeaters) and probably the best tarifs also in Spain (we are the MOST EXPENSIVE mobile-tarifs European country... ).
Here is my request.... Do you guys know if we will be able to get a "connection manager" tool so that my HD will not show "roaming" all the time, as it does not detect SIMYO as a local carrier?.... I always get the "roaming icon" when calling, and obiously if I try "connection wizard" I don´t have the option to chose SIMYO, as I can only chose Telefonica, Orange, Vodafone, even Yoigo, Carrefour Movil, Bankinter Movil, Euskaltel, etc..... but no SIMYO, and I had to enter Internet parameters and MMS setting manualy...
Hope anyone can gimme a hand over here .
Thanks folks!
MOD EDIT
Move to general discussion forum as not relevent to ROM development forum
Anyone?.... I am surprised that noone is having the same problem, as I think SIMYO is also existing in other countries...
same problem here
Hi again,
Now I've managed to unlock my Orange branded OSF and flash the SwedishSpring rom, I've been trying out different UK SIM cards.
Orange and T-Mobile work fine. Problem comes with 2 of the SIM cards I've tried from smaller networks:
TalkMobile - use Vodafone network
Tesco Mobile - use O2 network
For first 5 minutes there is a weak signal and then signal is lost completely only to come back weakly very intermittently.
Going into settings>network providers and trying to connect automatically to a network generates a message saying something like 'the network cannot register this SIM'. There is a list of the big networks (O2, Orange, T-Mobile, Vodafone and 3) and trying to connect to the 'parent' network fails.
The only thing in common with Talk Mobile and Tesco Mobile is that they 'piggyback' onto another network. There is no problem with the Orange and T-Mobile SIMs as I presume being in the list of providers means those SIMs connect without difficulty. The Talk Mobile and Tesco Mobile SIMs presumably try to connect to thier respective 'parent' network and fail once network recognises it isn't an O2 or Vodafone SIM?
The Talk Mobile and Tesco Mobile SIMs work fine in other phones, so not quite sure what's going on. Technical support at Tesco were useless saying, you have unlocked your phone in a non-legitimate way, therefore you can't expect our SIM to work properly (despite the T-Mobile and Orange ones working OK!)
I'm sure one of the tech/gurus/wizards here can provide more useful suggestions and help compared to the Tesco technical support department
Look forward to hearing your thoughts and if anyone else has experienced similar problems and how they solved them.
Thanks
PS. same problem exists even with the original stock Orange ROM prior to flashing FroYo rom.
From what you've mentioned, it sounds like your blade may not be unlocked.
I say this because since Orange & T-mobile merged as Everything Everywhere, their sims can be used to switch on to each others networks on locked devices.
Which method did you use to unlock your blade if I may ask?
Hi guys and girls,
Today, i'm writing my first post on this wonderfull forum. I have a problem.
I have very bad network sensivity on every Android phone i have. I'm kinda new to android but i know at least a minimum.
The questions:
If i buy a phone in a country and then take it to another country, can it lead to bad network?
Can the baseband version of a phone be good in one country and bad in another?
Are the OTA updates specific to a country (scandinavian android updated in a non scandinavian country) or are they different from a country to another?
The actual situation:
I live in Belgium but i'm norwegian and i'm used to Norwegian keyboards with Æ, Ø, Å characters) so I have bought my a SE Xperia X10 Mini Pro in Norway, but i think after i did the 2.1 update in Belgium i got bad network. Now i got a HTC Desire Z also bought in Norway and had perfect network in norway, i updated to the 1.72 still in norway and still had perfect network. Then i came back in belgium and had bad network. Then i updated to 1.82 and then to 2.42 (the gingerbread version 2.3.3) and i still have thebad network problems in Belgium. The rom is still the scandinavian/nordic and i was wondering if there is a different baseband version in the ota update from norway and the one from belgium eventhough its still the scandinavian sense rom.
If this is the answer to my problem.
Since i'm on a gingerbread Desire Z, how can i change the baseband version?
I guess i'll have to root, Is there a easy way to root a GB DZ?
Info:
Android: 2.3.3
Baseband version 12.56.60.25U_26.10.04.03_m
Kernel: 2.6.35.10-g7b95729
Software number 2.42.405.2
If you need more info or anything, just ask me. I really want to solve my problem and help others maybe find an answer to theirs.
Thanks in advance,
Bendik
Anybody? Please?
I really need help on this one.
define "bad network" are you sure the carriers in each country use the same bands? Radio loads and RILs will make all the difference. Have you tried locking to 2G?
Well, by saying bad network i mean i have between 0 and 3 bars most of the time. Even with nice weather.
I have no idea if my countries carriers use the same bands. But what i discovered was that if i use my norwegian sim card in belgium (roaming or something) and i use Mobistar (another network carrier) then i have 4 bars allways. I couldn't try to roam on base (my actual carrier) or proximus (wich is the lands monopol carrier).
The thing about radio loads and RIL's i didnt understand anything.
And locking in 2G doesn't change anything.
There are three carriers in belgium: Base (my actual carrier), mobistar, and Proximus (the countrys main carrier)
I ordered free SIM cards from the other belgian carriers.
I got one from mobistar and it worked perfectly.
I haven't tried proximus yet.
Base is the one i have problems with.
So no i have another question: Is there any differences between sim cards from one carrier to another one? Except that they dont allow me to connect to other carriers than the card carrier?
I know i may be spamming a little bit but this is kinda important to me.
So please, if anyone could give answers or help me i would be thankfull.
I think that not all carriers have the same signal strength in a specific location .
In my country there is three mobile networks and in my home they are not equal in signal strength .
one with zero signal , the second with moderate signal and the last one with perfect signal even though they are equal in the street which is 10 meters away from home !!!
You said that mobistar works perfectly so maybe you should stick with them and ignore the one you use right now .
Thanks for answering me.
I really liked base because i had so really cheap bills. Instead of paying 25€ for free texts and ringing and some internet im paying 10€ with my actual one.
I mailed base in case they could help me, and after about 2 weeks i finally got an answer. Theyre working on it...
Maybe it is the 3g band. Look, here in my city, if I use 2g, it works OK but in some areas i have no signal. If I turn on the 3G, I have a very good signal in almost every corner of the city. Verifiy that.
Hello,
-The easiest way might be to contact your actual operator, they should check the 2G/3G coverage in your area. But i guess you can do this yourself, somewhere on their website they should have a map with their signal strenght.
-Change your mobile phone; try the sim card in a different phone. Does it get the same signal strenght? - With this you will determine if the problem is in your mobile phone. If you get better signal in a different phone, you may have a broken anthena in your device or you've messed up something in the settings.
-Ask someone around you with your carrier what strenght does he get. If it is higher than yours and you got the same strenght in more than one phone you may have a wrong sim card. The carrier should change it for you.
Check this and let me know the result I'll try to help.

I am very interested to find out what Base does as I am in a similar situation to you though I bought my Xperia 10 mini pro here in Belgium.
When I use my Base sim card I have problems with the signal on either of the tree network settings.
When I use my Slovenian one, I don't have any problems roaming on Base, Mobistar or Proximus.
I always get a good signal when I use my Base card in a different phone though.
Sounds like the frequency for me! Check the frequency of the 3G band for your 3 operators and then check if your cell phones can handle that.
I saw that Mobistar (/the only carrier i get good network on has another band if i understood right)
Im still contacting my actual operator about the issue and they will need another 2 weeks before they can answer me... Of course...
SIM Card in another phone, in a 2G phone SE k550 i have full network. When i lock to 2G on my Android phone, it still has sucky network.
I have a friend (OMG) on the same carrier i had network problems with. he has allways full network, i'll try to see if i can make him come over and test the network with his android phone (acer liquid metal or something)
Ok, let us know how that goes
yes,you may lead to bad network.but the chances are little
Are you on 3g only?
In belgium, Proximus and Mobistar have the best networks.
Base has 97%coverage of edge, but their 3g network sucks.
Are you certain that its everywhere in belgium that base has a bad reception?
I contacted my operator, they told me to try to lock to 2G, i tried it for an hour and still no succes. I restarted my phone after i locked to 2G juste to be sure. Still no success.
I've allready tried in another phone, in my old SE k550 i have full network allmost all the time. I've had the same problem in my x10 mini pro even after a fresh original reset. I really dont think its the phone since i have perfect network when i'm on Mobistar (another carrier that is expensive).
I have a friend that has an Acer Liquid Metal (?) and i'll try to make him come over to test his network.
I have allready changed sim card but they made me pay 10€ for that... --'
Now i'm waiting about a week for another answer from my carrier.
I hope they can do something.
I have bad network everywhere except in the subway (underground :O )
I have this bad network with Proximus and BASE.
I'm was in auto HDSPA/GSM and than tried the 2G only, and now back to auto.
When i'm in auto, i think i noticed that in the moments i have Edge i tend to get better network. But when i lock to edge/2G i still have bad network...
I tried again to lock 2G and it works with full network. Still contacting the operator.
From a quick search of the internet it appears all the providers listed use the same frequencies, 2100 for 3G & 900,1800 for 2G.
As well as selecting 2G only I would also select the mobile operator manually, instead of automatically which I believe is the default. It is also a possibility that the Android phones sold locally have a different radio version then yours that works better on the Base network, I've run into this in the past with Windows Mobile on HTC phones.
