but these are my personal devices bought directly from a retail store, for example tmobile. brand new. and i dont own any company devices and have no association with a university. is this something that coms with my tmobile plan or something, i just have a basic magenta plan? personal plan. i ask because a while back, while update my iphone 13 it seemed like it crashed half way through the update and then seemed to have fixed itself but then it restored itself back to the way it was, then updated again and then seemed to be back to "normal" but it wasnt. in fact after updating, it actualy reverted back to what seemed like 3 or 4 updates agao because all of my text messages and voicemails from months and months ago that i had permanently deleted had been restored. i had never logged in to any account on my phone or ever backed up anything. so i thought maybe the phone might have to be wiped in order to update, so i took it to apple and they did a full factoryDf wipe but everything still got restored an now theres something that says managed configuration on my phone
