My blackberry curve 8520 have a network problem... edge isn't working

Hello sir,
am facing a serious problem with my blackberry curve 8520. My mobile network is based on edge. And since 2 days GSM is shown at the place of edge and if I make a out going call, it shows " the call is Failed" and even messages can't be sent. And I get a incoming calls with out any problem, when I get a incoming cal GSM is changing to EDGE and then I can make a outgoing cal..In order to make a out going cal from my mobile I should receive a incoming cal first to change GSM to EDGE. And some times edge changes to SOS and no network is activated. Please solve my problem.

The first thing I'd do is to get a free SIM card swap from Airtel.

How to download Thai Font to Blackberry curve 8520

My blackberry curve 8520, T-mobile network, ver 5.0.0.681 hasn't got Thai Font on it. I would like to download Thai font for reading and input (writing).please explain how to do it step by step because I do have not much knowledge about computer or software. I have read some topics says that I have to download and choose the network provider which mine is T-mobile and it provides only Muli-language (not All Languages) which I can't write it (only reading). I am not too sure it is correct or not.I believe I need to download Blackberry desktop software as well. please also give advice on these software.

Hi and Welcome to the Community!
The simplest way is to, on a PC (you cannot do this on MAC):
1) Uninstall, from your PC, any BB OS packages (add/remove programs, Uninstall a Program -- it depends on your Windows OS level)
2) Make sure you have the BB Desktop Software already installed
http://us.blackberry.com/apps-software/desktop/?lid=us:bboftwareesktopSoftware&lpos=us:bboftware
3) Download and install, to your PC, the BB OS package you desire:
http://us.blackberry.com/support/downloads/download_sites.jsp
If your carrier only provides a "Multi Language" package, then you may need to look at other carriers OS packages, and find some that have "East Asia" or "All Languages" ("Multi Language" indeed does not have Thai, as per this KB).
4) If that OS package is from a carrier other than the carrier for which your BB was originally manufactured, then delete, on your PC, all copies of VENDOR.XML...there will be at least one, and perhaps 2, and they will be located in or similarly to (it changes based on your Windows version) these folders:
C:\Program Files (x86)\Common Files\Research In Motion\AppLoader
C:\Users\(your Windows UserName)\AppData\Roaming\Research In Motion\BlackBerry\Loader XML
5) Now launch the Desktop Software and connect your BB...the software should offer you the OS package you installed to your PC, and you should be able to select the languages you desire If, during the process, your BB presents a "507" error, simply unplug the USB cord from the BB and re-insert it...don't do anything else...this should allow the install to continue.
Don't forget to backup.
If you are on MAC, you are limited to only your carriers sanctioned OS packages...but can still use any levels that they currently sanction. See this procedure:

Hi and Welcome to the Community!!
There's pretty much no diagnosing those -- they are the equivalent of the random errors in Windows for which tracing the root cause is fruitless. Basically, these are the last out in the programming code -- some event occurred for which there is no handler in the code. The fix is a code update that handles the event...but, again, knowing what the event is is pretty much impossible. So, there are a few things to try:
Sometimes, the code simply becomes corrupt and needs to be refreshed -- just like a reboot:
Anytime random strange behavior or sluggishness creeps in, the first thing to do is a battery pop reboot. With power ON, remove the back cover and pull out the battery. Wait about a minute then replace the battery and cover. Power up and wait patiently through the long reboot -- ~5 minutes. See if things have returned to good operation. Like all computing devices, BB's suffer from memory leaks and such...with a hard reboot being the best cure.
If it won't boot up cleanly, then you may need to try Safe Mode:
KB17877 How to start a BlackBerry smartphone in safe mode
There might be an updated code set from the carrier -- check them via this portal:
http://na.blackberry.com/eng/support/downloads/download_sites.jsp
The toughest possible cause is a badly behaving app. To find it, there are a couple of options. One is to see if you can read the log file:
Go to the home screen. Hold down the "alt" key and type 'lglg'. (You will not see anything while you type).This will bring up the log file. Scroll down (probably many pages) untill you see a line that says 'uncaught execption'. Click on this line. The name of the app will be in the info. Alternative methods for bringing up the logs are in this KB:
KB05349How to enable, access, and extract the event logs on a BlackBerry smartphone
The other method is to remove apps one at a time, waiting a while in between (I usually recommend a week), until the problem ceases...thereby discovering the offending app. Still another method is to reload the BB OS cleanly, leaving some time between adding other apps onto the BB so as to be able to determine exactly which one is the cause.
Good luck and let us know!

Blackberry Curve 8520 MMS problem

Hello!
Is anyone out there having this problem with a Blackberry Curve 8520?
My carrier is T-Mobile
Unlimited TEXT MESSAGING and MMS.
We upgraded to 2 Blackberry curve 8520 and had old MOTOROLA RAZR phone before.
With the Motorola and UNLIMITED TEXT MESSAGING with MMS, we were able to send pictures to other people via MMS. After upgrading to the Blackberry Curve 8520, we can no longer send pictures via MMS. When sending a picture via MMS, it sits there with the CLOCK and gets an X after a while. I even called T-Mobile and Blackberry and they have opened up a ticket. We were able to send pictures with the Motorola phones without a DATA PLAN and just with the UNLIMITED TEXT MESSAGING and MMS. There's gotta be others out there with this problem. I don't believe it that Blackberry opened up a ticket and don't have a fix for it.
Thank you!

This sounds like a provisioning issue on tmobile's end.

Blackberry curve 8520 wifi problem

Hi, I just got a Blackberry curve 8520 with T-mobile. I dont have the data plan iI think, since I thought I have wifi at home.
I connected the wifi but just the phone cant get access to internet, my computer can, also my other phone. So I went to the Options, Browsers, to change the setting, yet it only has 2 options: web2go (which cost money), and hotspot browswer (Which i don't think I have in my area). Helps, please.
Do I have to pay to have web access? Even if I have wifi at home?

Yes the 8520 is WiFi capable with UMA. Without a data plan you will need to set the browse up for Hotspots.

Appworld on Blackberry Curve 8520?

I have a Blackberry Curve 8520 and am trying to get appworld on it, but when I try to download, It says it is not supported on my phone.
Anyone know why this is?
Thanks

i have the same problem!
wat network are u on and where did u get it from?

Youtube on Blackberry Curve 8520 only working in 1 certain place.......why???

I can never get youtube to work on my blackberry curve 8520 (orange) except when im at my workplace.
At my work im connected to their wireless network, but im also connected to a wireless newtwork at home yet it doesnt work at home.
It also doesnt work anywhere outside.
Why would it only work in my workplace, something to do with my broadband provider at work? I cant seem to think why that should make a difference?
any help would be great.

It would have been great for you to mention what error you get when trying at home or anywhere outside of your work WIFI. I also have a Curve and I cannot play Youtube on Vodacom, problem is to do with bandwidth allocation by service provider, at work you might have higher bandwidth speed allowing video streaming, check if someone with similar phone on Orange is able to playback Youtube videos. The networks are not willing to release bandwidth for video streaming unless you will be billed extra like some networks do. Hope this solves the issue.

Right now i am using 2g plan but except browser nothing is working not a single application nor a wifi.
please help me I wanted to use these app on 2g plan not on BB plan or airtel.
So kindly provide me a proper resolution regarding my query.
I am requesting with warm warm warm regards

Do you have a BlackBerry Data Plan enabled on your account with your carrier or mobile provider?
You must, in order to get the RIM push email functions you are looking for, as well as additional BlackBerry data services such as the internet browser, Facebook for BlackBerry, BlackBerry Messenger, and much more.
So, call your carrier and inquire about having the BlackBerry Data Plan added to your account.
Good luck.

Do you have a media card installed? If so, remove the battery while the phone is powered on, remove the media card (leave it out), then reinsert the battery and let the phone fully reboot. See if that makes a difference or not.
