Australia’s largest telco, Telstra has unveiled a new range of plans called Go Mobile that will allow families to share data allowances and unify new phones and devices to a single account, according to reports.

According to a report on Gizmodo, Telstra’s Go Mobile plans will be available from May 12.

On any Go Mobile plan, customers can add a new phone by getting a AU$40 per month companion SIM that offers unlimited voice, SMS and MMS while sharing data from the original plan, reports CNET. Customers can also add new SIM enabled devices like tablets that can be included by purchasing the Data Sharing SIM for AU$5/month. The Go Mobile plan also features Telstra's Extra Data service that will add extra 1GB of data, incase users surpass their allowance but for this, users will have to pay a flat fee of AU$10, as reported by CNET.

The consumer plan starts at AU$55 a month for 1GB of Data and AU$550 of included calls and ascend to AU$195 a month for 16GB of data that will offer unlimited calls and SMS, as per the CNET report.

The Go Mobile Casual plans will also be offered with no lock –in contract. The casual plans starts at AU$35 a month for 500MB up to AU$70 for 6GB and besides that both data SIMs and companion SIMs can be added to Casual plans, reported CNET.

In order to cater to both business and consumer customers, Telstra has also come up with a Premium offering that features 16GB of data and built-in roaming with calls and 1.5GB of data per month, which will be available in eligible countries, CNET reports. The telco is also offering Go Mobile contracts with a 6-month subscription to either AFL Live, NRL live or Presto, as per CNET.

According to a report on Lifehacker Australia, the Go Mobile sharing plan will allow users to save some cash, if it is compared and calculated carefully. Telstra is charging heavy premium for sharing in comparison to its rivals. While Telstra charges $5 a month (ongoing) only for data sharing, Optus only charges a one-time $5 setup fee, reports Lifehacker Australia.
