Fixed-line giant may end its reseller relationship with former mobile unit PCCW and its newly acquired mobile arm, Sunday Communications, began cross-selling services at their respective shops yesterday, prompting speculation that the fixed-line provider will quit its reseller relationship with mobile service operator CSL. PCCW sales staff were selling the company's fixed-line telephony, broadband internet and Now Broadband TV services at all the 26 shops of Sunday Communications yesterday. Meanwhile, staff at PCCW's 14 shop outlets were selling Sunday's mobile service plans. Spokeswomen at both firms confirmed that a cross-selling arrangement had begun yesterday. PCCW completed its $1.16 billion acquisition of a 60 per cent stake in Sunday last week. 'As a first step, only our mobile service packages will be sold at PCCW shops,' said Sunday spokeswoman Stella Wong. Alex Arena, PCCW's chief financial officer, previously said that it planned to bundle Sunday mobile services with its fixed-line telecoms services such as broadband internet and sell it as a package. PCCW has also been reselling mobile services of CSL - its former mobile unit - at its shops after it sold the mobile operator to Telstra Corp in 2002. The new parent-subsidiary relationship with Sunday might put the arrangement with CSL into doubt, analysts said. 'Both sides would be unlikely to renew their reselling contract this year, as PCCW is already realising the benefits of enhancing its distribution channel from the acquisition of Sunday,' said CSFB telecommunications analyst Edison Lee. 'The number of new CSL subscribers recruited at PCCW shop fronts is insignificant anyway.' A CSL spokeswoman said the firm would review its contract with PCCW every year. The current contract is understood to expire within the next two months.
