We recently have been getting a bunch of these Pantech UML290’s in, and some users have experienced disconnects in 3G areas.
Fix :
Open up VZAccess
With VZAccess selected type CTRL + D
That should open up a window asking for a password, which is diagvzw
At the next screen, hit settings
Change Mobile IP to OFF
Set connection to Auto CDMA
Save settings and exit the VZAccess application
Shut down, remove aircard
restart, reinsert aircard with VZAccess already opened
This has reportedly boosted 3G and 4G performance, and much more sustainable speeds.
Wow, thanks…this actually fixed it!
