Telecom has upped the number of megabytes JetStream users can use per month without incurring further charges, giving residential JetStream 600 clients a boost to 1000MB and those with JetStream 400 an upgrade to 500.
The increase comes into effect this month, with subscribers becoming eligible for the upgrade on the date their March-April usage cycle ends.
The 20c per MB excess charge remains and the offer doesn't extend to business users.
Telecom residential group marketing manager Sandra Geange says the change was made to differentiate the 400 and 600MB plans, which, according to customer feedback, were perceived to be too similar.
"We wanted to provide [two services] which were significantly different and 500 or 1000 is a good distinction."
Providing more megabytes at no extra cost means greater costs to Telecom, but Geange says the company is banking on increased uptake compensating for the cost-of-service rise.
Approximately 15,000 residential customers now use JetStream packages, which all come under the JetStream label, now that JetStart has been re-branded "JetStream starter pack."
Geange says Telecom "would like to see that number rise substantially" and that more initiatives will follow.
