To take advantage of this Summer SIM offer, customers need to order NodeMobile and bundle their ADSL service and telephone line on a new 24-month contract with Internode. The offer also applies for new 24-month Naked ADSL contracts.

Internode's $20 SIM plan, called the NodeMobile Value plan, includes a monthly quota of $450 standard calls and text; $1000 of calls to other NodeMobiles; 1.5 GB of 3G Data; and 150 GB of social media data.

Existing Internode customers can also re-contract for 24 months to take advantage of this offer if they are uncontracted now or have less than six months to go on their existing contract.

Internode Product Manager, Jim Kellett, said the Summer SIM campaign highlighted the benefits for customers buying multiple services from Internode.

"This is a great incentive that rewards customers who bring their phone to NodeMobile and commit to a 24-month broadband service," he said.

"The generous call quotas and large data allowances of NodeMobile Value ensures this plan lives up to its name - especially when customers get free setup and six month in NodeMobile Value credits for free."
