I am not receiving half of the texts/calls sent to my Nokia 6 on ATT, but I can send them without issue. This started about a month ago after an update. The recent security patch did not fix the problem. I find it very frustrating that Nokia has allowed this problem to go on for a month. The phone can't do the basic features that a phone of 15 years ago could do. I do not recommend this phone to anyone reading this.
