Internode has increased data allowances for its NodeMobile Data service, first launched in April.

NodeMobile Data provides 3G wireless broadband access to Internode’s national network, making it an alternative to mobile broadband from the four main Australian telcos (Telstra, Optus, Vodafone and 3 Mobile).

Internode will charge $14.95 for 500MB of data per month and $39.95 for 5GB, a boost from 250MB and 3GB, respectively.

Internode product manager Jim Kellett said the increased quotas come as the first month of NodeMobile Data has demonstrated that the service "works seamlessly". "We’ve increased quotas to put out the welcome mat for even more customers," he said.

Internode confirmed that all existing NodeMobile Data customers will automatically receive the increased data allowances.

The NodeMobile Data offers customers the option not to be tied into an ongoing contract, and the doesn't charge excess data fees should users exceed their monthly data limit.

NodeMobile Data uses a Huawei E169 3G USB modem — the same hardware used by the the Virgin Mobile Broadband and Optus Wireless Broadband.

The NodeMobile Data service can be purchased for $199 without a contract, but is free when tied to a 24-month contract.
