I have an LG VK815 tablet that I purchased from Verizon and used it several years on Verizon's 4G LTE. When I upgraded my smartphone to an iPhone with Verizon I decided to remove the tablet from my Verizon account and use it only on WiFi. Now when I use the tablet it keeps trying to initiate an app that attempts connecting to Verizon cell which it cannot because Its cell number is no longer active. This occurs on initial bootup with a message that says it is setting up an app. which holds for a while and than an alert appears that says "sorry we're having trouble connecting......." with an option to close the alert. When I close the alert the tablet begins working properly on WiFi but every once in a while the same message and alert randomly reapears and interrupts whatever I may be doing. I cannot identify the app that is being set up and suspect it is something Verizon built into the software that doesn't appear in the app list to make the tablet almost unuseable without a cell account. Is this something I can correct?
