[Q] Problem: WIFI vs Mobile data connetion

---

I have a question regarding internet connections:

When I use WIFI connection, I can use all internet applications; Internet, Gmail, Daily Briefing, ....

When I use Mobile Data connection (GPRS), all Samsung applications says that there is a connection problem. For example; I cannot update the weather on Daily Briefing, etc.
However, all android application (like Internet, Gmail, FB) work without problems.

I thought that this is a problem with stock room, however, currently I am using JP3 and the problem is still here.

Any idea why is this happening?

Seems to me that your internet mobile provider is blocking some ports


Sent from my GT-I9000 using XDA App

Is there generally anything I can do to open those ports?

nope, they are blacklisted by your mobile provider

check if your APN is set correctly
Home screen -> Menu-> Settings -> Wireless and network -> Mobile network -> Access Point Names

Maybe "internet" is missing?

@freshko:
If I followed Irt01's steps and I have:
Planet internet and a green radio button.

I only used "Samsung Apps" once and it didn't want to work over 3G, when I enabled WiFi it worked flawlessly. I don't use any other Samsung's apps because there are better alternatives on Android Market.

Hej Yanni.

I sent you a private message. Did you get it?

1. make sure you have a data plan.
2. make sure your APN is configured properly
3. check that you are able to browse the net
4. try to sync with your gmail account on GPRS/3G
if that works, you should be able to run other applications, unless those ports are black listed by your cell phone provider, like for example FTP, IRC, Skype, MSN and other stuff like that

Probably they are blocked because as I said. I can browse internet, checking gmail, however, I cannot update weather from Daily Briefing. My data connection notifications goes from H to 3G, than back to H, and then I get: data connection error.
