$50 aloSIM Mobile Data Traveler eSIM Credit(opens in a new tab) for just $25 — that's 50% in savings for a limited time
Credit does not expire, and be used to buy data packages from any available country
e-SIM does not expire and can be recharged with Data packs
Data do expire — check website and country for data packages (Example: The $4.50 data package will last 7 days)
The data DOES expire, and you WILL NOT have any leftover data for your next trip unless it takes place within the validity period. While the eSIM never expires, the actual data package is only valid for the length of time stated at purchase (i.e. seven days after activation, 30 days after activation, etc.) So if you buy a seven-day package and only use a tiny bit, that package is still going to expire after seven days.
Because they charge in USD and there's a 10% GST (which the deal poster didn't take into account), it may be cheaper to buy it from an Aussie reseller (depending on your card exchange rate). Note that News.com.au gets a commission from the sale (as does Mashable)
