When I activated my Verizon Message , old messages (30 days ) appear, but none since May 1, 2015; I had several dozen on my old Samsung Galaxy S4. Any suggestions how to retrieve these newer messages? I was useing Samsung's messaging service on my Galaxy S4, but I decided to switch to Verizon's Messaging on this new phone. Since that doesn't work well, I tried using Samsung's messaging service on my S6. The same problem occurs. I cannot retrieve messages for the month of May 2015. I'd greatly appreciate any suggestions. Thanks.
