echo -e "AT+CGDCONT?\r" > /dev/ttyUSB0
+CGDCONT: 1,"IP","gprsinternet","",0,0
+CGDCONT: 2,"IP","business.gprsinternet","",0,0
from the info
+COPS: 0,0,"T-Mobile Austria",2 ( T-Mobile Austria is the registered provider )
+COPS: (2,"T-Mobile Austria","TMA","23203",2),(1,"3 AT","3 AT","23210",2),(3,"A1","A1","23201",2),(1,"T-Mobile Austria","TMA","23203",0),(3,"one","one","23205",0 ),(3,"A1","A1","23201",0),(3,"one","one","23205",2 ),,(0,1,2,3,4),(0,1,2)
the above shows T-Mobile have two connections available
+CGDCONT: 1,"IP","gprsinternet","",0,0
+CGDCONT: 2,"IP","business.gprsinternet","",0,0
the above shows two APN's on the device ("gprsinternet" and "business.gprsinternet")
The two plans may have different billing so from here it is important to select the correct APN , as
you could pay more or denied a connection if the wrong APN is selected , and also some plans have what is called
priority connections " I am assuming if your plan is "Business" then you may have special "Priorities",
one of those could be, when, trying to get a connection then you may have a higher priority over someone
who does not have special priorities,IE someone on a lesser plan may get bumped to give you the connection, since you
have a Business plan , notable at times of heavy traffic on the Internet(on specific servers)
one data-base of serviceproviders used by NM shows the below
so did you have to manualy set the APN
<name>T-Mobile</name>
−
<gsm>
<network-id mcc="232" mnc="07"/>
<network-id mcc="232" mnc="03"/>
−
<apn value="gprsinternet">
<username>t-mobile</username>
<password>tm</password>
</apn>
−
<apn value="web">
<name>T-Mobile (formerly tele.ring)</name>
<username>web@telering.at</username>
<password>web</password>
<dns>212.95.31.167</dns>
<dns>212.95.31.168</dns>
from the another data-base, info shows
APN "gprsinternet" = Plan "internet" and "Username = t-mobile , Password = tm "
APN "business.gprsinternet" = Plan "Buisiness Internet" and "Username = t-mobile , Password = tm "
So on to the connection
device dialing <cid> = "*99# = default *99***1#" = +CGDCONT: 1,"IP","gprsinternet","",0,0
which is not your plan
could indicate wrong APN may have been used at some stage "see details from first data-base"
other device dialing <cid> = "*99***2#" = +CGDCONT: 2,"IP","business.gprsinternet","",0,0
which is correct for your plan
open up the first terminal and enter this code
Code:
tr -s "\n" < /dev/ttyUSB0
open up second terminal and enter the following codes
Codes:
echo -e "ATZ\r" > /dev/ttyUSB0
echo -e "AT+CGDCONT=1,\"IP\" \"business.gprsinternet\"\r" > /dev/ttyUSB0
echo -e "ATDT*99#\r" > /dev/ttyUSB0
wait a second to ensure the "No carrier" message does not appear , if it does redial the number
at this point you may see in the first terminal "Connect" or "Connect <number>"
also note it is possible to dial the <cid> with this command " ATDT*99***2# " and avoid loading the CGDCONT=1 IE :the Line could be omitted
assuming there is a "Connect" message
enter this code in the second terminal
Code:
sudo pppd ttyUSB0 115200 nodetach defaultroute noipdefault noauth lock usepeerdns
enter your system password
what does the terminal show
to exit the pppd ,focus on the terminal window ,type Ctrl + C
