How to block a number on your phone
Blocking numbers on iPhone and in Phone by Google, questions for your operator and the limits of blocking.
Block the specific number
Blocking can help with repeated unwanted calls. It does not identify the owner or stop calls from other or spoofed numbers. Keep the call time and messages if you intend to report what happened.

iPhone
In Phone, open recent calls and the number’s details, then select blocking. In iOS 26, manage the list in Settings → Privacy & Security → Blocked Contacts. Older versions use different menus; voicemail may remain available.
Android with Phone by Google
Open call history, select the call and choose Block / report spam. Unknown blocks hidden numbers, not every number outside your contacts. Other manufacturers’ apps may use different steps.
What to ask your operator
Describe the situation to LMT, Tele2 or Bite support. Ask about available restrictions, costs and device requirements.
If you suspect fraud
Blocking alone is insufficient if you have disclosed data or funds are at risk. Read the response guide; report incidents through CERT.LV’s official channels.
Did you get a call from an unfamiliar number?
See what information is available about the number. Caller ID can be spoofed; an absence of reports does not prove a call is safe.
