I have a laptop- HP dm4 1203TU. It has a built in 3G module. The problem is I don't know how to use it. When I insert a 3G SIM inside the slot. It just tries to search the signal provider and after a couple of minutes, without a msg or report simply stops searching for network. Can anyone please let me know how to use the inbuilt modem in my laptop?.
I have an Acer laptop with built-in 3G. It came with some software called Acer 3G Coonection manager. Apparently the drivers provide a COM3 which is used by Windows built-in Dialup networking. It also provides a utility 'Acer 3G Connection Manager', which has a status line which tells me network type (WCDMA/HSPA etc) and network name.
I use Telenor in Sweden, and I had to confirm multiple times that I did not want a dongle when I ordered it. Apparently that was unusual. Then I had to call support at one time, and I managed to be connected to somebody who told me to change my APN setting.
It works reasonably well. Sometimes I can connect the network menu, but sometimes I have to use the Acer Connection Manager to connect. Only occasionally do I need to restart my computer.
If your providers support tells you that they only support their own dongle, look for drivers/software on HP:s web site. You could also try the manufacturer of the 3G module.
