How Much Money Can You Really Make Promoting Carrier SIM Cards?

According to the policy of a certain operator in a specific province

Commission structure: Below 300 users: 40% commission.
300–3,000 users: First-month recharge equals one cycle of the package plan, 40% commission.
3,000–4,000 users (exclusive): First-month recharge equals one cycle of the package plan, 50% commission.
4,000–5,000 users (exclusive): First-month recharge equals one cycle of the package plan, 55% commission.
Above 5,000 users: First-month recharge equals one cycle of the package plan, 60% commission.
7,000 users and above: First-month recharge equals one cycle of the package plan, 70% commission.
All commissions are paid out over 24 months.

In other words, for each SIM card—excluding the first-month recharge which we don't count—using the most basic user package at ¥30/month, the commission is spread over 24 months. If a user stays for the full two years, that's ¥720 in billed phone recharges. The minimum commission is 40%, meaning each user yields nearly ¥300 in commissions, while at the top tier, it can reach ¥500.

Promoting to this many users means tens of thousands of dollars in earnings. (This is also how many franchised carrier stores make their money.)
