Boost Mobile vs amaysim compared

In the battle of the big-name budget telcos, whose prepaid deals offer superior value?

Last updated:

Both Boost Mobile and amaysim have been offering prepaid plans to Australian mobile consumers for many years now. But what are the primary differences between these prepaid competitors?

Plan comparison

What to consider

Boost Mobile and amaysim both offer plans with unlimited standard national calls as the default. However, this doesn't cover every single call you might make, since some premium services still attract additional charges.

Where amaysim and Boost Mobile differ is in the range of offered plans. amaysim keeps its plans simple, offering five standard options that operate on a 28-day expiry period plus a pay-as-you-go plan that lasts for 365 days.

Boost Mobile, meanwhile, provides a wider range of options spanning 7-day, 28-day, 6-month and 12-month expiry periods. It does not offer a pay-as-you-go plan.

Low-cost plan comparison

While amaysim's $10 As You Go Plan doesn't include unlimited calls, it benefits from a very long expiry of 365 days. This could be a good fit for someone who wants a phone number as a contact point and doesn't need to make many calls or use much data. Plus, you can always top it up if you need to.

Boost Mobile's $10 plan does include unlimited calls and texts as well as 1GB of data usage, but its expiry is only a scant 7 days. That makes it a better match for tourists who just need short-term simplicity more than anything else.

Still, the main point of comparison for these plans is the data inclusions you get with them. We're all using a lot more data than we used to, so making the most out of your prepaid spend in data terms is vital.

Network coverage

Boost Mobile and amaysim operate on different mobile networks in Australia. Boost Mobile uses Telstra's full 3G and 4G networks, while amaysim operates on the Optus 4G network. This gives you slightly different coverage profiles with each plan, although for the majority of city and town-dwelling Australians there's arguably not that much of a difference. If you travel regionally or rurally a lot, Telstra's network is hard to beat, but if you're more metropolitan, the extra data you get on many of amaysim's Optus-backed plans is hard to beat.

Still, a little research can go a long way, so if you're weighing up Boost Mobile or amaysim, it pays to check your particular location against their expected coverage maps. Coverage maps are only a guideline, not a guarantee, but they're a good first step.

While Telstra's full "4GX" network can deliver blistering speeds of up to 1Gbps (at least in theory), Boost Mobile's access to the network is the same as any other Telstra MVNO. This means that your download speeds are limited to a maximum of 100Mbps. In near-identical fashion, the speeds you'll get on amaysim through the Optus 4G network also top out at 100Mbps.

In real-world testing, you're not likely to hit that 100Mbps point all that frequently, with speeds in the 20-50Mbps range far more likely. For all but the most demanding applications, that should be plenty.

International calls

If you frequently call overseas (or want to), then having the ability to do so at a low cost is an ideal inclusion. Boost Mobile gets a high score for its upper-tier plans which provide unlimited standard calls to a wide selection of countries plus an amount of calling minutes for other countries bundled into your prepaid deal.

amaysim likewise bundles in unlimited calls and texts to selected countries in its upper-tier plans, though these inclusions are applicable in fewer countries than Boost Mobile offers.
