[Q] 3G don't work in my xperia mini pro - Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A

Hi, I have a xperia mini pro(sk17a) and my problem is that the 3G don't work in my cell phone, I was reading ont the internet and maybe my cell phone doesn't support 850Mz band(I am from Peru and 3G works in 850mz).
Is there any solution? or maybe there is any way(software) that my cell phone can work with 850MZ

Settings - wireless and networks - mobile networks and check if there is 3G chosen. If yes and phone doesn't use it, then maybe no 3g in your area.

The question is, if topic starter means internet connection or 3G signal.
Which phone do you have, Sk17i or Sk17a? Both are Xperia Mini Pro, but have different 3G bands. You can check it in Settings - About phone and there is model number.

the problem is that when I activate the enable data in my cell phone(to use the mobile network to connect to internet) I only see the letter "E" that means 2G(Edge) and never appear "3G" or "H"(HSPA), and I Know that the problem is in my cell phone , because I have other cell phone that can connect to 3G without any problem but my xperia mini pro "SK17a" cannot.
for this reason I think that the problem is my cell phone don't support 850 band
I know some samsung galaxy phone have the same probleme ,don't support 850 band , and they can change their modems to make the the cell phone could support 850 band. but I don't find a modem for the sk17a with android 2.3.4.
features of my cell phone

Sk17a supports 3G 850 MHz band, so it has to be another problem.
Settings-Wireless and Networks-Mobile Networks - Mobile operators
Can it find your operator's 3G network? If yes, try to manually register it, just click on it. If not, then your phone cannot find it. My LWW doesn't always connect to 3G, if it isnt strong enough.

I have same problem(sk17a). My other device working 3G.
What the defference between "3G" and "E"DGE?
Just speed only?

Did you find a solution?

Flashing sk17i baseband might solve your problem

You might need to fix your APN settings, which are located at Settings- More- Mobile networks- Access Point Names. Google your carrier and APN (for example, "ATT APN"). I came up with a couple of different configurations which I saved in separate APN names and played with them until I figured out what worked best for me. Hope that helps you out.
