Yes, you can terminate your service anytime but there will be charges involved.
You are required to pay back the remainder of the contract using the rateplan’s promo price and it is calculated as per below:
Balance charges = RM50 x remaining number of months of contract
The remaining number of months will be deemed to include the month during which you terminated the phone package.
Example: If you terminate in Month 5, the U Mobile U Biz 98 Promo Price is RM50, you are required to pay U Mobile RM50 x 20 = RM1,000 per line.
