If you have signed a loan contract with SimTrade or other financial institutions, you need to fulfill the repayment obligation according to the contract. If you violate the repayment agreement, you will face certain legal risks and extra expenses such as interest and late fees.
If it is really impossible to repay according to the repayment method and time limit agreed in the contract, it is recommended to contact SimTrade or other financial institutions as soon as possible to discuss the repayment plan. You can ask to extend the loan term or reduce the monthly repayment amount to better adapt to your repayment ability.
