OCCOM sim-only mobile plans are all postpaid, featuring an ongoing auto-renew that renews on a month-to-month basis. Every month you’ll receive a bill, and at the end of that billing cycle, your plan inclusions will automatically refresh, making it simple for customers to pick a mobile phone plan that suits both their wallet and usage habits. The bill will have a fixed amount at the end of each month. If you exceed your data limit or SMS allowance, the services will continue; however, excess charges will be added to your next monthly bill.
