retrieve text messages lost phone

All I want to do I receive any messages I may have gotten today since I left my phone far far away at my mom's home. I don't care about any old messages just new ones. I thought ATT should have been able to help me but they were useless. I also downloaded imazing with no luck. its an iPhone 4s and the pc I'm using right now is windows 10. No iTunes on this pc and I don't want to install it on my buddy's computer. I can manage my icloud and att accound but cannot find a way to see any new texts. I desparately need them because I use 2-step email authentication....so not I cant get my email!
