3G not working

[YXD]

I'm having major trouble with my phone and need some help.

I've got a standard Vario III no flashed roms etc..

When I'm on standard GPRS network the phone works fine, calls internet etc..

However whenever it switches to a 3G or H network I cant make or receive calls or use the internet. The funny thing is that when it tries to access the internet it looks like it connects but when you click on the 3G (with the arrows) it says there are no sessions active.

Help!!

maybe I have the same problem, I can't make calls, when I make a call it do a sound alert and end the communication.

The line is ok, I was using it with other phone without problems. I spend today 5 hours with the mobile service provider (CLARO ARGENTINA) tech service and they finally say this must be a problem with the pda, not with the service (after testing all possible alternatives)

The phone is almost new! I can connect to EDGE and navigate the internet, H or 3G appear "some times" but it get EDGE 99% of the time.

When somebody call me the phone ring and then then lost connection. When people call me they receive a "network error".

1 of 20 times I CAN do a call.

Do you think is the phone? or there is some update ? I'm downloading a 6.1 rom to test with it.

it is not the phone. Assuming your are using T-Mobile, Edge network coverage is almost 100% complete, while T-Mobile's 3G network is in the early stages. So you will usually get Edge until 3G is nearing completion - T-Mobile is slow :P

Well I use Claro AR (in Argentina). EDGE is 100% and 3G is quite well in my city, but what do you think about my phone calls are closed after 5/6 seconds with error and then it lose phone coverage. Never happened with other phone, same provider, same line, other phone.

Now I have updated to a duttys Rom with a newer radio version (1.65.x, my phone comes with 1.21.x) and still happening. Now I will test another rom :(

It IS the phone.
If you do a search on this board lots of people are having that problem, as I found when encountering it myself. It's a hardware fault in the radio part, that requires sending the device back to HTC. They actually replace the whole mainboard to cure it, so it's a serious issue.
Awaiting to receive mine back, it's been there for a month now :(

Here's a large thread about it: http://forum.xda-developers.com/showthread.php?t=335074

thank you :(
I force the phone to run under GSM network (not WCDMA) and the phone works perfect, internet too (only EDGE). But I can't use 3G because if I set it to WCDMA or AUTO in the phone network section, it's unusable.

That's the one. I'm receiving my Kaiser back from repair tomorrow, can't wait, and hope it will be fine this time... It's been at the service center for 6 weeks now :mad:

[mblendinger]

hello, any news ?

[kilrah]

Yep, received it back like 3 weeks ago, everything works flawlessly. They replaced the whole mainboard just like for the other people with the same issue.

:( Ok I'm dead. Sending the devide to north america from Argentina? now way.

[kilrah]

Why? I had to send it to the UK, not much of a problem...

[mblendinger]

Ok I will call tomorrow the seller to ask the guarantee. let's see what happen.
