So, I recently bought an unlocked Blackberry Curve 8520 from Newegg. Before I put in the SIM, I tried out the WIFI feature and it worked awesome. When I put the SIM card in, that's when my WIFI stopped working. I have T-Mobile and whenever I use the browser it always transfers me to the Home Page, telling me I have to purchase the web2go plan. Currently for my old phone, I don't have any data plans except for unlimited texting. WIFI is supposed to be free no matter what from what I understand like if you are connecting to your own router from home. I don't understand why it doesn't work anymore once I insert my SIM card. Does any one here know how to fix this problem? Sorry, I am new to Blackberry and the forums itself. Any help would be greatly appreciated.

Nevermind, I answered my own question. For anybody else having this problem, all you have to do is follow this very useful guide here: Complete WiFi How-To - BlackBerry Forums at CrackBerry.com

Not working for me - 8520 using AT&T prepaid sim :(

Ok just paid the $49 to talk to a BB techie and he confirmed that AT&T blocks wifi usage even though the cell is unlocked and even though I have wifi. I turned on the phone w/o the SIM and voila, internet worked. So, from a physical standpoint it seems that:

with sim = no wifi
without sim = wifi

Any way to program the SIM so it doesn't enable blocking of wifi w/o paying $30 a month for data?

nope

Yeah this sucks - I guess I'll have to return it. Really don't want to get locked into a contract.

Hi, I also new for this forum, and just bought bb 8520, is there any way to connect to wifi ?

I've tried to connect to AP with WEB encryption, but the message is could not get the IP even the password correct.

Hi Guys, After ugrade to new OS, now I can connect to wifi, and get an IP from my AP smoothly, but when I open the bb browser the browser wont allow me to connect to Internet, is there any way to baypass this things ?

Looks sucks, since I stay in ASIA region, there is no such thing wifi service plan.

make sure the browser is set to HOTSPOT BROWSER

Yep, its done, and I enable the data in network setting.

You're best bet is to either change the encyption on your BB Router (from WPA to WEP possibly) and/or once you are connected to your WiFi network go to Manage Connections, then Set Up Wi-Fi Network then you should have a 4th option saying Wi-Fi Hotspot Login.

That "should" tell your BB to use the Wi-Fi connection over the GSM connection for data etc

Have you used opera?

bb browser is the best for me

i want the bb browser, but tmobile just gives the web2go, which only gives me access if i purchas e a plan. i tried the hotspot thing, doesn't work.

i just got a curve 8520 and sad to say, but im starting to hate it! at first it was connecting to the internet using EDGE then by the end of the day i saw that it said gprs on top, which made my browsing much much slower. now i cant even log on to any website. what is wrong with the phone? could it be the phone or the server? my server's Globe since its the usual around here where I live.
