Telstra will change its 365-day prepaid mobile broadband offering next week, adding up to 2GB in data allowance but charging an extra $30 for the recharge.
The carrier accidentally leaked details of the change in a summary pdf document on its website, which was noticed by a Whirlpool user.
The document revealed that the current $150 recharge that offered up to 10GB of data with a 365-day expiry had been replaced by a $180 recharge option offering up to 12GB of data allowance instead.
The document was retracted late last night after questions by CRN sister site iTnews.
However, a spokesman for the telco confirmed the impending change.
"Next Tuesday we're introducing a new 12GB recharge for prepaid mobile broadband customers that's valid for 365 days. This replaces our current 365 day recharge," the spokesman said.
"We've found many of our customers on the 10GB plan are using their allowance within the 12 month period."
The new 365-day prepaid plan is proportionally no more expensive than the plan it replaces.
"The cost per MB is marginally better than the outgoing 365-day option - 1.46c per MB v 1.47 per MB," the spokesman said.
The plan change comes into effect on June 12.
