How do you block a number with tmobile?

Answer 1

Presently you cannot block phone numbers under T-Mobile unless you are using the Family Allowances plan and there is a fee ($2 per month at the time of this writing) for its use.

It will not block anonymous nor private callers and there is a limitation for up to 10 numbers only.

Old Answer:

It all depends on the phone now... I know on my HTC HD2, I can go into settings and block a number if I really wanted too.

Also, you might want to see if it is in your plan to do so, because I know select services like Call Waiting, Voicemail, etc. are apart of you plan. I have an unlimited everything plan, so I have every service available.

Answer 2

ring up customer services to find out about it.

Answer 3

*67 to block you number, in other words, the person receiving your call will not be able to see your number.
