In the past week, for the first time in the four years I’ve used a smartphone, I’ve received several spam text messages from “Blocked” and “9999999”.
I was annoyed, and puzzled about how to get this to stop.
After some exploring, this is what I discovered.
Canada’s major cellphone companies have mechanisms to stop spam from reaching you. But sometimes the spam slips through. You can alert your phone company by forwarding the text to 7726, with SPAM in the subject or body.
This won’t necessarily stop the spam immediately, but it can help the phone company block future spam from the same source. Forwarding the alert to 7726 can also cancel the text message fee if you are not on an unlimited texting plan.
(On an iPhone running iOS7, you can forward a text by putting a finger on the message for a second or two; select More, you will get a forward arrow. Touch that arrow, and fill in the blanks. For spam arriving in Apple's iMessage system, see below.)
Complaining to the phone company isn’t all that satisfying because you’re relying on someone else to solve your problem, who might not.
What has worked for me is a change to the notification settings on my iPhone. (Similar functions are available for other smartphones.)
Unwanted texts are at their most annoying when they trigger a ring or a buzz. You can change the notification settings to prevent those messages from bothering you. The message will still come through, but your phone won’t buzz and won’t display a text notification.
On an iPhone running iOS7 (this feature is not available in earlier versions) go to Settings —> Notification Center. Scroll down to Messages. Scroll to the bottom and activate Show Alerts from My Contacts. That disables Show Alerts from Everyone, which is the default.
Only messages from someone in your Contact list will trigger a notification. This means you’ll need to add notification-worthy people to your Contact list.
To set up a block, the spam sender needs to reveal a phone number or email address. That’s unlikely to happen, and even if it does, the spammer likely uses numerous numbers and addresses. So, you’re at the mercy of the phone company when it comes to blocking spam from unknown sources.
On the iPhone, running iOS7, set up a block with these steps: Go to Settings —> Messages (or Phone, or Facetime) —> Blocked (which is at the bottom of the window) —> Add New, and then select the contact you want blocked. This assumes that you’ve created a contact for the offending number.
You can also do it this way: With the unwanted message on the screen, touch Contact at the upper right of the screen, then on the next screen, touch the I-symbol-in-a-circle at the upper right, then scroll to the bottom and select Block this Caller.
Other platforms, such as Android, have similar features. See below.
At some phone companies, there may be options to block certain types of text messages when you log into your account on the web. For example, you could reject all text messages that don’t originate from a phone number.
Calling the phone company on a voice line to register your spam concern might be worth a shot. I haven’t tried that.

Apple’s iMessage system is separate from the phone company’s texting service. If you get spam through iMessage, you can follow these instructions from Apple.

Third party apps are promoted as spam blockers. I haven’t tried any of them. Some charge a fee. The reviews are not particularly effusive. Do a search for “text blocking apps”.
