Cannot make international calls from my mobile,it says that it is service not available

if you have a package then land line and mobile charges are included in the package and are not separated
There is a package the Telstra sell that is for 2 land lines , net connection, land line hire and 25 gig of data for around $120.00 a month and all calls local, national and international are free except for 1300 numbers
however if the land line is inoperative you are entitled to a refund on that rent cost for the period it is not available and if incoming calls are redirected to your mobile , that cost is on the caller
ring accounts and make your point or contact the ombudsman and make a complaint or shift service provider

FIXYA unpaid volunteers cannot arrange your cellphone or credit cards.

It appears you are asking about cell phone calling but I may have misunderstood your question.

https://www.consumercellular.com/Help/international-rates/roaming
You can use your Consumer Cellular service when traveling outside the U.S. by enabling international roaming. The countries where our service can be used are listed here.
Consumer Cellular utilizes multiple network providers. The network provider your specific cellular service uses determines international roaming availability. To confirm your international roaming options, contact Customer Support at (888) 345-5509. We recommend doing so at least two weeks before leaving the U.S.
On some networks with Consumer Cellular, usage incurred from the countries listed will be billed at international roaming rates of $0.30 per talk minute, $0.10 per text message, and $0.25 per MB of data usage. On other networks with Consumer Cellular, those costs can be much higher, or international roaming may not be available. Be aware that when using your phone internationally, charges can add up, so it is always best to use on a more limited basis. For your protection, service will be disabled once we have received billing records showing $50 in international roaming charges has been incurred on your account during a billing period (this includes calls, text messages, and web data). Due to delays in receiving billing records, your charges will likely have exceeded $50 when international access is disabled.
