  1. Check Your Current Contract: Before making any changes, ensure your current contract is up for renewal or free from obligations.
  2. Choose Your New Mobile Network: Research and select a mobile network provider that best suits your needs in terms of coverage, plans, and pricing.
  3. Order a New SIM Card: Place an order for a SIM card from your chosen provider, either online or by visiting a local store.
  4. Back Up Your Data: Ensure all your contacts, photos, and important data are backed up to avoid losing anything during the switch.
  5. Receive and Activate Your New SIM: Once your new SIM arrives, follow the activation instructions provided by your new network provider.
  6. Test Your New SIM: Insert your new SIM card into your phone and ensure everything is working as expected.
  7. Request a PAC Code: If you want to keep your existing phone number, contact your current provider and request a Porting Authorisation Code (PAC).
  8. Provide PAC Code to New Provider: Share the PAC code with your new provider to initiate the number transfer process.
  9. Wait for the Switch: Your new SIM will be activated, and your old one deactivated. This usually takes a few hours to complete.
  10. Test Your New SIM again after your old number has transferred: Insert your new SIM card into your phone and ensure everything is working as expected.

If you did not request a PAC code, you should inform contacts of your new number.
