amaysim runs on the Optus network, so its voicemail works just like Optus's — everything happens through 321. When your voicemail service is activated, amaysim texts you a PIN; call 321, enter it, and record your greeting. From then on it's press 3 to update your greeting and press 8 for user options like changing your PIN. Below is the full walkthrough, including roaming access and how to get a professionally produced recording onto your amaysim line.
Once your voicemail service is active, amaysim sends you a voicemail PIN by SMS. Open the phone app, call 321, and enter that PIN when prompted.
The prompts take you straight to recording your greeting. The maximum length is 180 seconds, but keep it short and catchy — 15 to 25 seconds is the sweet spot for keeping callers on the line.
Once your greeting is recorded, change your voicemail PIN to something personal you'll remember: press 8 on the main menu. Your PIN can be any combination of 4 to 9 digits — avoid repeated numbers like 1111 for security.
Your mailbox is now live. From now on, dial 321 to listen to messages, press 3 to update your greeting, or press 8 for user options including group lists and PIN changes.
Already have a greeting and want to replace it? Dial 321, press 3, and record a new greeting — it overwrites the old one as soon as you save. You can change it as often as you like, which is handy for annual leave or public holiday messages. One tip: on amaysim, a system prompt plays after your greeting, so don't say "leave a message after the tone" yourself.
From any other Australian phone or landline, dial 133 321, enter your mailbox number (your mobile number), press #, enter your PIN, and press # again. From overseas, dial +61 411 000 321 and do the same. If you're roaming, the easiest option is to text the letter A to 321 — within 30 seconds the service calls your mobile back with your messages.
amaysim voicemail is a prepaid-friendly service with no extra monthly charge on current plans — check your plan's inclusions for call rates to 321. All the day-to-day controls live in the 321 menu: 3 for greetings and 8 for user options (PIN, group lists, notifications). If calls aren't diverting to voicemail, check your handset's call forwarding settings or the amaysim app, and make sure your voicemail service is activated on your account.
amaysim records greetings through the handset, so there's no upload button — but there's a reliable workaround used by thousands of businesses:
Phone lines compress audio heavily, so a well-mastered recording captured this way sounds virtually identical to a direct upload.

"Hi, you've reached [Your Name]. I can't take your call right now, but I check my messages regularly and I'll get back to you as soon as I can. Thanks for calling."

The amaysim voicemail number is 321. Dial it from your amaysim mobile to set up and access voicemail. From another Australian phone, dial 133 321; from overseas, dial +61 411 000 321 and enter your mobile number and PIN.
Dial 321 from your amaysim mobile and press 3 to update your greeting. Record the new greeting after the tone and follow the prompts to save it. Greetings can be up to 180 seconds long, but 15–25 seconds works best.
When your amaysim voicemail service is activated, a voicemail PIN is sent to you by SMS. Enter it the first time you call 321, then change it to something memorable by pressing 8 on the main menu. Your PIN can be 4 to 9 digits — avoid repeated numbers like 1111.
amaysim doesn't offer a direct file upload for personal voicemail greetings. The reliable workaround is to play a professionally produced MP3 from a second device close to your phone's microphone while recording your greeting via 321. Phone lines compress audio heavily, so a well-mastered recording captured this way sounds virtually identical to a direct upload.
Either text the letter A to 321 and the service will call your roaming mobile back within 30 seconds, or dial +61 411 000 321, enter your mailbox number (your mobile number in Australian format), then your PIN, and follow the prompts.
