      Your calls – your choice!

      The Call Filter is your chance to avoid unwanted conversations if necessary. In different life situations, another Call Filter list may be useful for you.

      • White List – only those people whose numbers you have included in this list will be able to call you. Other callers will not disturb you.

      • Black List – those people whose numbers you have included in this list will not be able to call you.

      • White List+ will be useful if you want to avoid unnecessary spending in foreign countries, where you also have to pay for received calls – only those people whose numbers you have included in this list will be able to call you.


      Welcome to the nearest LMT Customer Centre.


      The White List and Black List of the Call Filter can be used very simply – activate or cancel the filter, create lists of numbers and make changes to them via text messages.

      If you administer the White List, send text messages with the corresponding keyword to the number 29319920,

      if the Black List – to the number 29319910.
