The Bestie pack will enable friends and families to keep in touch during this festive period at low call rates.
Chief marketing manager Parag Panjwani said: “December has always been about family and celebration.
“So the Bestie pack is our way of bringing the spirit alive through our products and services.
“This December, anyone can buy one SIM card and get the other for free.
“People can choose to give the second SIM to their friends or wantoks.
“This gift could help them save money by making the most of the affordable call rates and the unlimited voice bundles.
“We have consistently been working on delivering the best value for money to the people of Papua New Guinea and will continue to do so.”
Group chief executive officer Sundar Ramamurthy said: “With our growing presence in Papua New Guinea, both in network reach and retail availability, we are confident that more and more people will be able to make the most of this offer.
“You can now walk into any shop to buy bmobile-vodafone products.
“The retail price for the Bestie pack is K5 and is written on the front of the pack.
“This is to let all the customers know of the price and to prevent other retailers from selling it at a higher price.”
