[Q] Baseband Switcher and Radio region how to - Defy Q&A, Help & Troubleshooting

hi there i put an Etisalat sim in my defy (CM7) but no signal , so after searching n asking i knew i have to use Baseband Switcher and change something in my radio? would you please tell me what to do im newbie thanks alot

it all depends on your country and network.
In Australia we have 3 networks.
Telstra, Optus and vodaphone I think the other is.
Now there are heaps of mobile carriers but they will use one of these networks. Telstra is the easiest as they wont off sell there network to any other carrier. Optus and vodafone how ever they will sell them off to all the other carriers and what carrier uses what is up to them.
Your best bet is to ring your carrier ask what network they use and you should be able to find it in the baseband switcher.
If that fails google the carriers for your country and try them all in the switcher one is sure to work

You may also need to Carrier unlock (CID) your phone in order to use the new SIM card on another provider.

blocked phone

i have recently bought an xda exec that is blocked to uk networks.
will a three network sim work in it?,has anyone tried?
If it's blocked to UK networks, it's ALL UK networks sorry...
When you say "blocked" do you mean that it is IMEI blacklisted or that there is a network lock on the phone that stops you using UK SIMs?
If it is IMEI blocked you're stuck. I haven't read of an IMEI change solution for the Universal yet, but that is illegal anyway (prison sentence illegal, not just a smack on the wrist).
If your phone is SIMlocked you can use the unlocking tool on Buzz's site to disable all locks.
the phone is unlocked,but says no sevice,if i put in a virgin sim it has a signal but you cant make calls.
Thats good then,, its unlocked but Virgin doesnt have settings for the Universal yet so your a little stuck other then that try flashing it with Tmobiles ROM that may help as Virgin is a sub group of Tmobile

please don't post answers like this when you don't know what you're saying to be 100% true.
a) ROMs don't affect gsm service - it's all contained in the SIM (that's what SIMs are specifically for). every rom of a particular version of wm has the same phone program - just different skins.
b) gsm communication is standard across all handsets - there are no "settings for universal" other than for MMS and a few other things (which are not the subject here)
c) virgin rent bandwidth from a number of companies including t-mobile (i.e. they are a virtual provider)

How to flash HD2 to Cricket?

I tried searching everywhere and still no answers.
Does anyone know if it is possible to flash the Htc Hd2 to cricket or metropcs.
they are network providers, so i assume you mean unlock the phone to use them?
no flashing will not do that. you would need the network unlock code, however isn't metre cdma? if it then the hd2 cannot work on it.
Yes as long as the network uses GSM (sim cards )
So theres no way htc hd2 can be turned into cdma and be flashed to metro or cricket?
you cannot flash a phone to unlock it. as stated above you need the unlock code, you can get this from your network provider for approximately £15 just tell them you are leaving the country for a holiday and want to change your sim card to a local network sim card in the other country (to get a better rate). If you would prefer you can easily unlock your phone on the internet, again for aground £15-£20, just search on Google.
as for your other question about cdma im not to sure.
re: cdma i'm only 95% sure but i think you're out of luck, i think its a whole different hardware.

[Q] Is my phone sim unlocked?

Hello everyone. I recently moved overseas and I'm new to the GSM market. I purchased a HTC Magic from a friend who says that it's SIM Unlocked. I've been using it in Italy (where I currently am now) with no problems, but soon I will be moving to Turkey. I would really like to know if there is some way to tell if the phone is unlocked before I go to Turkey to make sure I don't have any downtime. If I go to Wireless & Networks/Mobile Networks/Network operators, I can see other local networks, but can't select them because I'm assuming the SIM I have will only work with one provider.
I've done some searching, but didn't see any answers for the Magic specifically.
Anyways, is there anyway to tell if this phone is unlocked?
Thanks in advance.
Put in a sim from a different provider (borrow from a friend?) And if it works then it's unlocked

[Q] Bad Network On Android Phones

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.

Hi guys
I have got a Galaxy S4 i9505 with a label that it's a European model and will works with sims in the europe. Could someone please help me on what does that mean? I have tried searching and reading but it's all conflicting statements.
1) Do I activate it with my UK sim card and then it can be used anywhere in the world?
2) Do I take my UK sim card everywhere I travel around the world and first switch on the device with UK sim and then later on swap the sim with local to use the phone?
3) Can I use the phone normally and then use a software which can enable the phone to use any sim in the world?
Thanks
