## Mobile Shared Data Pack (Optional Account Add-On for Crazy 5G Voice SIMs)

**Share one flexible data pool across your team's 5G mobile SIMs**

Add 50 GB to 1,000 GB of shared backup data to your CrazyTel account for **$0.275 per GB a month (inc GST)** ($0.25/GB ex GST). Each SIM uses 100% of its own monthly plan first, then automatically draws from your shared pool - with **$0 overage charges, ever**.

- **Only $0.275 / GB per month (inc GST)**: Choose any pool size from **50 GB ($13.75/mo)** up to **1,000 GB ($275.00/mo)**. Add or remove eligible SIMs for **$0.00**.
- **Own Plan First, Shared Pool Second**: Your SIMs always use 100% of their own included monthly data before touching a single megabyte of your Shared Data Pack.
- **Zero Bill Shock & Instant Data Restore**: Never pay surprise per-GB overage fees. If a SIM is data-paused for hitting its plan limit, adding it to your pool or upgrading your pack restores mobile data automatically within **1-2 minutes**.

### How the Mobile Shared Data Pack Works (4 Simple Steps)

1. **Choose your monthly pool size (50 GB to 1,000 GB)**: Pick the pool size that suits your business or family in the CrazyTel MyAccount portal (`Optus SIM-Cards -> Shared Data Pack`). Your pack activates immediately.
2. **Select which Crazy 5G Voice SIMs can share the pool ($0 per SIM)**: Add any active SIM on a **Crazy 5G Voice plan** (20 GB, 50 GB, or 100 GB 5G Voice) at no extra per-SIM cost.
3. **SIMs use their own plan allowance first**: Every SIM uses its own monthly data allowance as normal. Only when a member SIM reaches **100%** of its individual plan does it begin drawing from the Shared Data Pack.
4. **Protected against overage charges**: If your Shared Data Pack reaches 100%, mobile data on over-limit SIMs simply pauses until the 1st of next month - or turns back on within 1-2 minutes if you upgrade your pool size. Voice calls and SMS continue working normally.

### Plain-English Billing, Upgrades, Downgrades & Turn-Off Rules

| Action | Charged Today | When It Takes Effect | What Happens to Your Data & SIMs |
|---|---|---|---|
| **Create a Pack** | `Pool GB x $0.275` (inc GST) from your prepaid balance (no pro-rata) | **Immediately** | Your pool is active straight away. Any selected data-paused 5G Voice SIM has its mobile data restored within 1-2 minutes. |
| **Upgrade Pool Size** | `(New GB - Current GB) x $0.275` (inc GST) for the extra GB added | **Immediately** | Your pool grows right away and renews at the new size on the 1st of each month. Any data-paused member SIMs have their data restored within 1-2 minutes. |
| **Downgrade Pool Size** | **$0.00 today** (no charge today, no refund) | **12:00 AM AEST on the 1st of next month** | Nothing changes this month - you keep your full current paid pool until the end of the month. On the 1st of next month, your pool resets to the smaller size and lower monthly price. |
| **Cancel a Scheduled Downgrade** | **$0.00 today** | **Immediately** | Cancels your scheduled reduction so your pack stays at its current size on the 1st of next month. |
| **Turn Off Pack** | **$0.00 today** (stops all future monthly renewals) | **12:00 AM AEST on the 1st of next month** | Because you already paid for this month, your SIMs keep using your remaining pool until the 1st of next month. You can turn your pack back on anytime before the 1st for **$0.00**. |
| **Add a SIM to Pool** | **$0.00** | **Immediately** | Any data the SIM used above its plan limit *before* joining is not counted against your pool. If the SIM was data-paused, its data turns back on within 1-2 minutes. |
| **Remove a SIM from Pool** | **$0.00** | **Immediately** | If the SIM is over 100% of its own plan, its mobile data pauses on the next usage check (~2 minutes). Any pool data it already consumed this month stays counted against this month's pool until the 1st reset. |

### Shared Data Pack FAQ

- **Does unused Shared Data Pack data roll over to the next month?** No. At **12:00 AM AEST on the 1st of each calendar month**, your Shared Data Pack resets to its full monthly allowance and renews from your prepaid account balance. Unused pool data does not roll over.
- **Is the first month pro-rated if I create or upgrade a pack mid-month?** No. Creating or upgrading a Shared Data Pack charges the flat rate of **$0.275 per GB (inc GST)** immediately so that the full data allowance is available to your SIMs straight away. If you create or upgrade within the last 24 hours of the calendar month (AEST), the portal will ask you to confirm that you understand the pack resets and renews on the 1st of the upcoming month.
- **If one of my SIMs is already data-paused because it used 100% of its plan, will adding a Shared Data Pack turn its data back on?** Yes. As soon as you add that Crazy 5G Voice SIM to an active Shared Data Pack (or upgrade a full pack), CrazyTel automatically queues a mobile data restore with the network. Mobile data is typically back online within **1 to 2 minutes**.
- **What happens if I remove a SIM after it has already used data from the shared pool?** Removing a SIM is free (`$0.00`) and takes effect immediately. Any pool data that SIM already used during the current calendar month remains counted against this month's pool until the 1st of next month so your pool usage stays accurate.
- **What happens if my Shared Data Pack reaches 100%?** We never bill excess data charges. When the Shared Data Pack reaches 100%, any member SIM that has also used 100% of its own monthly plan will have its mobile data paused until the 1st of next month - or you can upgrade your Shared Data Pack size at any time in MyAccount to restore data immediately. Voice calls and SMS remain active.
