CLEAR STEPS. VERIFIED CONTACTS.

Stop the harm. Find help.

If money is at risk, call your bank first. Do not wait for an email reply. There is no shame in asking for help.

End a suspicious call. Do not approve anything else. Do not transfer money to a supposed “safe account”. For immediate danger in Czechia call 158, or 112.

I have an unwanted SMS subscription

PREVENT FURTHER CHARGES

Protection through your mobile carrier

Premium SMS are paid messages. Audiotex means premium-rate calls, including Czech 900, 906 and 909 numbers. Cancel the subscription, then block further payments. A payment block alone does not cancel a subscription.

T-Mobile ↗

You can ask: “Please block Premium SMS, mobile payments including Apple and Google billing, and premium-rate calls. Help me find recurring charges.”

O2
  1. On O2’s website, select your plan and open settings for SMS payments. Configure the service and block everything.
  2. Also block internet payments. This includes Apple, Google and Microsoft purchases.
  3. For payment by calling, keep the service active and select the option to block everything. Making the service inactive alone does not block premium calls.
  4. Cancel subscriptions with the provider. O2 commonly specifies STOP ALL to the first five digits of the service number. Help: 800 02 02 02.
