Is it legal to charge telecom in advance?

Whether the mandatory prepayment of telecommunications is legal or not depends on the laws and regulations of specific countries and regions and the specific operation mode of telecommunications companies.

In some countries and regions, telecom companies may require users to deposit a certain amount before purchasing their mobile phone numbers, so as to pay for future telephone charges, SMS charges, internet charges, etc. This practice is allowed in some places, but it may be banned in others.

In addition, if the telecommunications company takes unreasonable measures such as compulsory consumption to require users to pre-recharge, then this practice is likely to be illegal. For example, if a telecom company forces users to pay a certain amount in advance, and users do not explicitly agree, then this behavior may be regarded as compulsory consumption, which is illegal.

Therefore, if you think that the compulsory prepayment behavior of telecom companies is illegal, you can consult the local communication management department or consumer protection agency to understand the specific legal requirements and complaint channels.
