1. Check whether you have inserted the SIM card correctly. 
  2. Then turn your smartphone completely off and on again.
  3. Now everything should work properly.

If you kept your phone number when you switched to Teleboy Mobile, please check the date and time of activation of your SIM card. 

We have informed you of both by e-mail. Your Teleboy SIM card will not work before this date.

If it still does not work, please contact our support.
