The practical reality of an online outage is that if the problem is with the mobile network and not with your phone, then unless you also moonlight as a network engineer for the affected telco, there’s not so much you can do to get the actual service back up and running.
What you can do is get back online in the meantime, especially so if there’s pressing work or study to do. Or even just to finish out that Netflix binge while you wait for your phone to go back online, we won’t judge.
Here you’ve got a few options. The cheapest would be to check local businesses and services that might offer free Wi-Fi; your local public library is often an excellent place to start, but you could also opt for the free Wi-Fi that many shopping centres or shopping districts offer as well. Bear in mind that some of these services do require sign-ins with emails that may be used for marketing purposes, and many will also have their own strict data usage and/or time limits. Public payphones – if they’ve got the distinctive pink top – also offer Telstra-based Wi-Fi for free to all consumers even if you’re not a Telstra customer, though this won’t be much use if it’s Telstra having the network outage of course!
Your other option – and especially well worth considering if you’re constantly seeing outages or suffering through poor connectivity – is to consider switching both provider and network.
There is generally little point in staying with a given network and just switching who your billing is coming from; if you went from one Optus MVNO to another you’re still going to be hit by any Optus network issues, and the same is true for either Telstra or Vodafone.
Here’s a range of affordable phone plans across all three networks for you to choose from:
