"The import duties on CDMA handsets are not fair. Mobile handsets using the same technology comes in duty free. We need a level playing field," Suntel's Chief Executive Jerry Huxtable told reporters.

However, the BOI last week wrote to Suntel and Lanka Bell (the other WLL operator) asking the firms to pay up with retrospective effect.
Huxtable says the import duty on CDMA stands at around 18 percent, but the overall tax on each unit now goes up to 33 percent with immediate effect.
