If you do not need to keep your current mobile number, you can request a STAC from spusu and give it to LycaMobile.
You should receive a STAC code and information about any account charges.
LycaMobile will use this to close your old service without transferring your old number.
Your old number will not move across. Only choose this route if you are happy to lose or stop using your current number.
When you are ready, visit LycaMobile to continue your switch.
