This is very strange.
Have you the possibility to try to use the TP-LINK modem under Windows in your or an other computer?

yes i did it and it work perfectly


wvdialconf on your Linux does detect the modem /dev/ttyS0
yes it detect it i saw it, and it is detected fine

Can you switch off the power on the modem and check that wvdialconf does NOT detect /dev/ttyS0 when there is no power on the modem?
i did it too and it is detected when is powered on, and when it is powered off is not detected by the wvdialconf, and i probe with the smartlink too and do the same thing

Is the cable with which you conect the modem to the PC the original TP-LINK cable?

yes, it came with the original box with all  the modem staff

Do you have an ohm meter to verify that the cable is not broken?

Are you using the same phone cable to connect the internal modem and the TP-LINK modem to the wall?

yes, i have only one cable i to the modem conection and i use it with the 2 modems
I cannot think of any other issue than a bad cable or connector.
hey i think,why whe i do a tail -f /var/log/message with the smartlink modem it show various information about the process but with the tp-link y show nothing, think about it, is very strange

Having two configurations in one file makes life more complicated.

I have seen your file with two sections as below:


[Dialer Defaults]

Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0&C1&D2 +FCLASS=0
#Stupid Mode = yes
Modem Type = Analog Modem
ISDN = 0

Modem = /dev/ttyS0
Username = islanis@xxxxxxxxxxxxxx
#Carrier Check = no

[Dialer interno]
Init = ATZ
Init2 = ATQ0 V1 E1 S0=0 X3&C1&D2 +MS=90
Stupid Mode = yes
Modem Type = Analog Modem
ISDN = 0
Phone = 060110
Modem = /dev/ttySL0

This model can work if you start the SL modem  with command     wvdial
interno
or the TP-LINK modem with command      wvdial

If this is what you do then the problem comes from the TP-LINK version
trying to use the modem as   /dev/modem   which is no more than a link
to /dev/ttySL0   not connected to the wall.

Just remove the link /dev/modem   with  command      rm /dev/modem
and try again, first the TP-LINK and then the SL modem.
If you ever need /dev/modem again, the command is         ln  -s
/dev/ttySL0   /dev/modem
(or ttyS0  if you want the TP-LINK to be /dev/modem  ).
Do not forget the    -s   option in the link  (ln)   command.

Be aware  that other dialers than   wvdial   define their own
/dev/modem   (example kppp, qinternet). All that depends on which
version of Linux you use.
i made all that and nothing, is still without conection, i ma in my home
now and the 2 configuration are these


[Dialer Defaults]
Init = ATZ
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0&C1&D2 +FCLASS=0
Modem Type = Analog Modem
ISDN = 0
Phone = 060110
Modem = /dev/ttyS0
Username = islanis@xxxxxxxxxxxxxx
Password = **********
Baud = 115200

[Dialer interno]
Init = ATZ
Init2 = ATQ0 V1 E1 S0=0 X3&C1&D2 +MS=90
Stupid Mode = yes
Modem Type = Analog Modem
ISDN = 0
Phone = 060110
