JumpySIM uses parts of the Telstra Mobile Network that covers more than 98.8% of the population with 3G* and 97.9% of the population with 4G.
Please note, even if you are living in an area that has coverage, connectivity via a mobile network can be impacted by a variety of factors. Please ensure you check the coverage in your area. JumpySIM Australia does not offer refunds on credit purchased due to a lack of coverage. * Telstra’s 3G Network (850Mhz band) will close in mid-2024.
