If you have an international number that you wish to use with your Sim Local SIM card, you cannot keep your existing phone number.

If your existing number belongs to the same network SIM card that you are purchasing with Sim Local, you can transfer your existing phone number by contacting the network provider directly and ask them to transfer your number to the new SIM card, as long as you have a PUK code.

When it comes to using any Apps associated with your existing number, you can continue to do so with your new Sim Local SIM card. Your Apps will remain associated with your existing phone number.
