[bviijay]

Hello,

I bought two Nokia E71 mobiles with BSNL 3G connection. My service provider(BSNL) providing 3G service. E71 is connected to PC there i dialed to another phone which is conneted to other PC. when i dialed from hyperterminal in winxp by using ATD commnad with out semicolon. I am getting connection error messge on my phone. NO CARRIER on hyper terminal.
I don't know what the problem is i tried with all commands no use. Is there any setting required for NOKIA E71. How to make data call (CSD call) by using Nokia E71.

You help is very much appreciated..

As a first check, you could visit Settings/Connection/Access points, and see if you can set Data call as bearer when creating a new access point. If yes, that would indicate that you have chances with data call.
An other thing you may want to check is if your mobile operator assigns separate phone numbers for data calls. At least when I used CSD, I had a separate number for that.

Thank you for the reply.
I have the following accesspoints by default...
bsnlnet
bsnl mms
bsnl stream
bsnl wap
bsnl live

I checked with the service provider the CSD service is activated and there is no separate number for data call.
When i am trying to create new access point there is no search for bearer so how to create new access point for Data call.

In technical specification E71 is supporting CSD and HSCSD both.
I am searching for documents but didnot find any clue. Is there any AT commands need to execute before ATD command.

Please help..

Thank you

When i am trying to crate new access point in the data bearer field only two options are there packet data and wireless lan.
But in the Nokia E71 technical specification CSD and HSCSD are there.

Unfortunately I have no clues. Searching for atd in the Wiki ('Community' panel, top-right corner) reveals two articles, and they do not see to apply any special initialization sequence.

Hi
After ATD9540234123
I am getting NOCARRIER on the Hyperteminal(on PC)

then
AT+CEER?
+CEER: Incompatible destination

Wat's that mean is there any problem with E71?

Thanks
