I started getting text messages on my ATT phone from email addresses that couldn’t be blocked.
I switched to straight talk.
I'm glad you were able to find a plan that allowed you to block texts. I have had Verizon Wireless for many years. When I had to switch from a 3G phone to a 4G phone, I went with the cheapest iPhone they had, because I've only owned Apple computers. I don't sync my phone with anything on my computer. Basically, all I use my cell phone for are calls, Bing Search points, and the occasional text message for doctor appointments and prescriptions. The iPhone allows you to block text messages by clicking on the individual sending the text, then clicking on "info." By scrolling down that page, I can block the senders, then delete their message.
