So I spent an hour and a half on the phone with technical support yesterday, couldn't get the issue resolved and they told me to get a new SIM card. Went to my local store and got a new SIM card, still having the same problem.
Called tech support again today and was on the phone with them for 2 hours, still no resolution. They just told me to do a factory reset and see if that helps. Such a pain in the butt!!
Now I am finding out that my mom has also been having problems with calls constantly dropping since the recent software update, so it has to be related to this.
