Hi Devindrappa,
1.Could you please post new ppp-log. It would have changed for sure.
2.As venkat suggests remove rild startup from init.rc and re run and see
what happens. Comment out the rild service.
3.I will look into the error but ril has very little influence, if not
none, in establishing a data connection. The ril is doing everything it is
supposed to do. It is for telephony services only.
4.I'm not sure but i think "the preffered network type" has to do with a AT
command which sets whether to look for a 2G or 3G network first {or} the
network scan order to register in the specific network. It sets its order
to scan for networks. It is for 3G modems. I had experience with it when i
was working with a huawei modem. It may not apply in your case because your
modem doesn't support 3G and hence it's AT command is not accepted. I will
look into it and get back to you with confirm answer.
5.IF you think it is a sim lock for the time being you can simply replace
the sim and go ahead. A lock is sim specific. A modem won't report a lock
unless sim states so.On Wed, Jan 18, 2012 at 8:27 PM, Devindrappa Handraki < devindrapp...@gmail.com> wrote: > Hi Chaitanya, > > 1.
