How to check whether your Unicom number is a contracted user through SMS or online business hall?

To check whether the number participates in the contract plan, you can first check whether the number is refunded or given away.

You can log in to the online business hall/click Query Phone Charge > Phone Charge Query > Account Balance; Check the frozen amount, which is the remaining total amount authorized by your contract. Just divide the frozen amount by your monthly appropriation, which is the term of your contract.

For the specific number to participate in the contract plan, you can log in to Unicom's online business hall for online shopping guide consultation.
