We’re sorry to see you go! To ensure a smooth closure and avoid any unexpected charges or loss of data, please review the requirements below before submitting your request.
⚠️ Critical Pre-Cancellation Checklist
30-Day Notice Period: All SIM services are subject to a 30-day notice period. This begins the day we receive your formal request.
B2B Contract Terms: As ONSIM provides Business-to-Business (B2B) services, please note there is no 14-day "cooling-off" period.
Keep Your Number (Porting): If you want to keep your phone number, you must port it to your new provider before your cancellation date. Once the account is closed, numbers are released back to the regulator and cannot be recovered.
Account Balance: Your account must be settled in full before a deactivation request can be finalised.
Broadband & Fixed Services: If you have broadband or other fixed-line services, our team will review your specific contract and advise on any remaining terms or early termination fees.

Note: Your service will remain active and billable until your confirmed cancellation date.
