Per the title, I'm planning to buy a fall alert / help monitor pendant for a family member, but it requires a SIM. I don't think it uses data (but need to check), just uses it's GPS module and initiates a phone call & text messages if the alarm is activated.
Like this model, which includes a Telstra SIM & is locked to Telstra 850MHz:

Are there any 365-day annual plans or prepaid SIMs out there? if so, who's the best?
Aldimobile $5 will last you a year on AYG.
