If you find that the Australian 4G card you are using has poor reception, try using a non-domestic brand of mobile phone. Australia has a total of 5-6 4G spectrum bands available, while domestic all-network mobile phones only have 3 spectrum bands suitable for Australia, half of which are not used.

It's said that they are almost the same.
