Error that iPhone 6s Plus is not activated?

priyapam

    I’ve had my T-Mobile phone over two years and never had any issues. Now I suddenly keep getting the error that my iPhone 6s plus is not activated, and my phone tells me to contact my carrier. Texts to non-iphones  won’t go through. T-Mobile gave me a new SIM card but that didn’t fix the issue. Any thoughts?
