I upgraded to the Note 8 a few weeks back and noticed that I have not been receiving some texts from people. Its not limited to one person and not one particular provider. Its random. I have talked to customer care a few times and they say that on the system it shows the texts being delivered but they are not going to my phone. They are saying its the phone. I have seen similar instances now surfacing in the USA with Verizon. Is this a handset issue?
