CellOne has expanded its customer care service to 24 hours a day, seven days a week.Customers will now be able to inquire about billing, make rate plan changes, troubleshoot problems, or make bill payments at any time following the soft launch before Cup Match.“We understand that it’s hard for our customers to call in or get to our stores for help within normal business hours,” said Frank Amaral, CellOne’s chief operating officer. “Now that we offer 24/7 customer care, our clients can be more flexible and talk to agents whenever their schedules permit.”This follows the launch of CellOne’s 4G network, merger with M3 Wireless, new flagship store opening and brand changes earlier this year.The CellOne customer care number is 700-7000 or 611 from any CellOne phone.
