Text recipients getting duplicate or more texts from me

[marlow02]

Hi, I am on the Rogers network in Canada. Have had two other phones(huawei and samsung galaxy core lte) with this sim card and never had this issue a single time. But since day one of using my asus zenfone 2 my text recipients keep asking me why I am sending the same texts over and over. I have noticed sometimes when I am sending a text it doesn't send right away, and it says "sending" for quite a few minutes. I believe this is when it is firing off duplicate or more texts. I have even gotten replies to texts that still said "sending" so it was obviously already sent. This issue is driving me crazy. Any ideas what to look for to fix? I am confident it is phone related and not carrier related issue.
