your ISp dial up number is set in windows not on the phone.
on port map data you will set your connection cable or Bluetooth
you can dial your your current HOME ISP but the connection will be slow
the best way is to use the 1x back door, the number to dial is #777, your ID is your cellphone number number@vzw3g.com
PW is vzw
follow these instructions in this post, it is the same for the enV as for the lg8100 in the post
so many people are getting NEW phones ( Vcast capable phones ) and want to use the 1x network connection, here are some directions, these are detailed for the lg 8100 on verizon, will work for the 8300 and 9800 and possibly the 5200
this works for my LG vx8100 and should work for your LG from verizon
press MENU
now press the number 0
the screen will say enter service code
now press 0 6 times
a new secret menu list will appear
look for NETWORK SELECT ( on my phone it is number 3 in the list )
choose NETWORK SELECT and press OK
another menu choose 'Mode Preference' press 1 or OK
another menu
with 4 choices
choose '1X Only'
press OK
this will lock the phone to 1x mode
now press END
it should work for you
If you need to setup the phones PC connection and DUN ( dialup networking )
that is also in the service menu
selection #4 'Data'
nothing about this will change your voice phone calls
VOICE calls do NOT use EvDo ( digital hybrid ) mode that you turned off
all you have done so far is , set the phone to act like older phones that did not have Ev-Do broadband data speed capability,
in the service menu under data, scroll down to PC connection and choose 'cable DUN' and choose enable and OK
all you need to do now is make sure the PW & ID are correct in your dialup connection settings
or create a new dialup connection
PW is VZW the ID is cellphonenumber@vzw3g.com
example 5551235656@vzw3g.com
the number to dial is #777
Create your connection
when you go to connect for the first time, click Properties, go to the "Security" Tab, then under security options, you need to select the radio button next to "Advanced (custom settings)" then click the settings button just to the right of the radio button..
when that dialog box comes up, under the "Allow These Protocols" section, you need to uncheck everything but the "Unencrypted Password (PAP)" option. Hit "OK" on the bottom, a dialog will come up saying something about if the connection uses one of the protocols that you just un-selected it wont work, just press "OK", then press "OK" again.. then you will be back at the login screen for the DUN connection.. Press "Connect" it should work from there..
I hope these directions help
