If prepaid users don't recharge all the time, our company will automatically take back the number after the deadline; If the post-paid user owes more than 3 months (the number is frozen for 90 days), our company will recover the number. You should also pay the fees you owe, otherwise you will become a blacklisted user and cannot handle Unicom business. If you don't need to use them, please cancel your account in the local business hall.
