Why did I receive a text saying I’m not getting important messages?

We noticed there’s a setting on your account which blocks all commercial SMS messages. These messages include communications like one-time PINs, security codes, promotional codes, appointment reminders, fraud alerts and more. We sent you a text to let you know we’ve removed this block so you can receive these important messages.

I’m getting a lot of these messages, and I don’t want to block these messages one at a time. Can’t I just block them all? What’s the risk if I do?

In order to ensure you receive important messages—including communications like one-time PINs, security codes, promotional codes, appointment reminders, fraud alerts and more—we do not recommend blocking all messages. You can reply to any unwanted messages with STOP, END, CANCEL, UNSUBSCRIBE, or QUIT. If unwanted messages continue, forward the message to 7726 (SPAM).

I’m not receiving security code texts from my bank. What’s the deal?

If you are not receiving important messages, a block may be be enabled on the number(s) that the specific business uses. Please contact Customer Care to check whether a block was applied to your account.
