Connection Failed : airtel 3G USB Modem

Hi,

I'm currently in India and I've bought an airtel 3G USB modem, but I can't make it work.

Bus 001 Device 045: ID 12d1:1436 Huawei Technologies Co., Ltd.

1) Sakis3G
Connexion fails (juste after giving username/password)

2) Networkmanager (with modemmanager)
A broadband menu is successfully created in the NM applet. But when I click on "airtel", I get a connexion fail

3) Wvdial

[Dialer Defaults]
Modem = /dev/ttyUSB0
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
INIT3 = AT+CGDCONT=1,"IP","airtelgprs.com"
Stupid Mode = 1
Modem Type = USB Modem
New PPPD=yes
Phone = *99***1#
ISDN = 0
Username = a
Password = b
Baud = 460800

I get

CONNECT
--> Carrier detected.  Starting PPP immediately.
--> Starting pppd at Wed Jan  4 16:30:45 2012
--> Pid of pppd: 22965
--> Using interface ppp0
--> pppd: ~[7f]
--> pppd: ~[7f]
--> pppd: ~[7f]
--> pppd: ~[7f]
--> pppd: ~[7f]
--> pppd: ~[7f]
--> Disconnecting at Wed Jan  4 16:30:51 2012
--> The PPP daemon has died: A modem hung up the phone (exit code = 16)
--> man pppd explains pppd error codes in more detail.
--> Try again and look into /var/log/messages and the wvdial and pppd man pages for more information.

I've been Googling for an hour without solving anything. Could you help me please ?
