Hello. The delay ranges from about 10-12 hours to as much as 30+ hours. It started while I was with Straight Talk (using Verizon towers). I thought that switching to actual Verizon would solve the issue, but it hasn't. I haven't ruled out bad actors like man in the middle attacks or SIM hijacking, because when I did get a break from this problem, it was after I switched to Verizon (new SIM, no message issues for about 2 months), and when I changed a Sim recently (no texting delays for about one month). Anyway since someone might say MITM or SIM hacks are crazy, I am just wondering if I can get any help to solve this issue, or if someone could actually verify that my device is the only device attached to my phone number. I use Google's messaging app. For some reason, when I tried Message+, it would not get all of my texts.
