Will my phone number remain the same after transferring from another network? And how can I check what my phone number is?"

It should do, @Krzyszt_2630876. The procedure for keeping your number is explained online at:

You can check your mobile number by looking at your SMARTY account's "Dashboard" online. 
Do this at https://smarty.co.uk/dashboard.

@Krzyszt_2630876  When you first activate a Smarty sim, it is allocated a random number.

If you then complete the request to port in your number, you need a PAC from the old network and smarty can arrange to move your number onto your new sim.

Sometimes, you need to change the number manually in your phone.

You can log into you account dashboard and it always shows the number that is associated with your account.
