Under this partnership, both parties will offer applications and digital services to customers of SingTel Group companies, including Advanced Info Service (Thailand), Airtel, Globe Telecom (Philippines), Optus (Australia), SingTel (Singapore) and Telkomsel (Indonesia).
It will also allow the two companies to leverage each others' distribution channels to extend their retail reach.
