According to the article, (http://www.smh.com.au/business/the-economy/tpp-points-the-way-for-cheaper-global-roaming-20151006-gk2hxp.html), Australians could enjoy much cheaper calls when travelling overseas thanks to global roaming provisions in the TPP agreement. One of the provisions of the TPP could slash the exorbitant fees that many mobile providers charge for Australians when using their phones abroad.

The TPP agreement states that “If a Party chooses to regulate rates for wholesale international mobile roaming services, that Party shall permit operators from the TPP countries that do not regulate such rates the opportunity to also benefit from the lower rates.” This means that, for example, if mobile regulators in Japan sign a deal to slash roaming fees for their citizens, then Australians travelling in Japan will also benefit from the same low prices.

Still, mobile customers may have to wait some time for these provisions to kick in, as a roaming agreement between Australia and New Zealand regulators has already been in negotiations for years.
