Hi all, having a long term phone problem here! When i got my k800i to replace my k750i, it was an o2 phone so i just popped my current o2 sim into it and all was fine, including 3g, for which there was constantly an icon at the top of my screen. Anyway, one day i wanted to see if i could get rid of the icon, so i went into my settings and changed it to 'GSM data only' and obviously it turned off 3g and got rid of the icon,etc. But now i want to have 3g back, and everytime i select '3g and gsm', it spends a few seconds configuring, resetting the network, and sure enough, the 3g icon does come back, but then 1 of 2 things happens: it will either just disappear again after a few seconds, or a new icon will appear next to it, a phone with a line through it, and my status changes to 'Emerg. Calls only' - then, both icons will disappear, and the 'normal' o2 network returns. I am at a loss! It's nothing to do with my area, as the blue 3G icon was ALWAYS there wherever i went when i first got the phone. Any ideas people? Any special settings i need to use? Would be awesome if you could get this working for me!
thanks

Of course when you swicth from 'GSM' to 'GSM & 3G', the phone will first search and connect to the GSM network as default. After that it will try to search for the 3g. A little waiting will do it.
Or perhaps you should go Connectivity - Mobile Networks - Select Network and from there you can search for the 3g network and select it manually.

So as long as you hav'nt switched sim cards (from o2 3g sim card to o2 normal sim) you should be ok with the mini tut @yea g told ya

So I need a special sim card do I?
Cos my SIM i got about 3 years ago...but when I got my K800i phone, like I said, it was an o2 phone so I just popped my current o2 sim in there and it worked fine and I had the 3G.
I haven't changed sim or anything since, the only thing I changed was the GSM option (which I now wish I hadn't!) and now the 3G won't stay enabled when I select it! Grrr!
What's this mini tutorial you mention?
Thanks

@alex-ncfc, i think that you operator has a problem with its network,... Because when the phone appear with a red barre...... This means that it's no signal...you cant make a call or connect to the net.......
Anyway ask your service provider for good informations...
