TPO.. how to block spam text

TPO.. how to block spam texts?

9999 block (number)

Does not seem to work. Failed


Just wondering... are you on TPO with Sprint (CDMA) or T-Mobile (GSM)? If it's the latter, you might want to check the T-Mo website for tips on blocking.

If you're on Sprint, here's the latest info I could find re: 9999 commands: Be part of the in-crowd. | T-Mobile Community

One other suggestion: I downloaded the "Hiya" app on my phone, and it does a fantastic job of blocking spam calls. Not sure about texts, though.

EDIT: In the interests of full disclosure, my phone is on Twigby, not TPO... so as they say, YMMV.

Tpo gsm.

9999 did not work. Now I understand why
