Activation of a replacement SIM card only takes a few hours to activate. However, activation of a new service with a new number will be completed in 1 working day (In most cases the service will connect instantly and you'll simply need to insert the SIM into your device).
If you're looking to transfer an existing number to SpinTel, your SIM will become active once the transfer process is complete. Most transfers will become active within a few hours but the process can take up to 24 hours to complete.
During the transfer you can continue to use your current provider's SIM. Once it stops working, that’ll mean your SpinTel SIM is ready to go.
