- Pools are for one end organisation only — cannot be aggregated across multiple customers
- No data banking or rollover — pool resets to zero at the start of each billing cycle (28th)
- Plan changes take effect on the 27th of each month
- Services that leave a pool lose their contributed data and must change to a non-pooling plan
- Bolt-ons apply to the pool as a whole, not to individual services

How does the data bank work on standalone plans?
On standalone plans, unused data rolls over into a data bank each billing cycle:
- 4G plans: data bank limit up to 500 GB
- 5G plans: data bank limit up to 1000 GB (D-5G-XXXL excluded)
⚠️ Pooling plans do not have a data bank. The pool resets to zero at the start of each billing cycle — unused data does not carry over.
⚠️ When downgrading a plan, the existing data bank is cleared. Always confirm with the customer before proceeding.
What data top-up options are available when a customer runs out of data?
Once a customer exhausts their plan data and data bank, top-up bolt-ons apply:
- Auto Top-Up: 2 GB per pack at $9.09 — activates automatically. Maximum 5 auto top-up packs per billing cycle
- Manual Top-Up: 1 GB per pack at $9.09 — ordered manually. Available after the auto top-up limit is reached
How do I upgrade or downgrade a customer's plan?
In the Comms Portal: Services → select service → Advanced tab → Change Plan. Plans available are shown as cards — the current plan is marked with a Current Plan badge. Click Select Plan on the desired plan and confirm.
- Plan changes take effect on the 27th of each month to align with the billing cycle (28th–27th)
- Upgrading: data bank remains intact
- Downgrading: existing data bank is cleared — always confirm with the customer first
- Only 2.0 plans are shown for 2.0 services
What is the billing cycle?
- Billing cycle: charges and inclusions are metered from the 28th to the 27th of each month. Your CommsChannel bill is issued at the start of the following month
- Plan activation: prorated according to remaining days in the billing cycle
- Plan disconnection: not prorated — no credit applies for remaining days
- Plan changes: take effect on the 27th of each month
- Data bank renewals: roll over amounts are also metered from the 28th to 27th
Which countries are included for unlimited IDD calls, SMS & MMS?

Portal & Services
What does the Partner Dashboard show?
The Partner Dashboard gives a real-time summary of your customer base and service activity, including: total customers, active services, orders generated, active Travel Packs, plan distribution, activation types (new vs port-in), SIM type distribution (Physical vs eSIM), and a Service Trend section covering activations, churn rate, port-outs, and cancellations.
How do I check order status and service activity?
Services → select service → Activity tab. Auto-refreshes every 30 seconds. Order statuses:
- Acknowledged — received, not yet processing
- In Progress — actively processing through carrier back-end systems
- Complete — finished successfully
⚠️ Never re-submit an order showing In Progress — this can jeopardise the service. If stuck for more than 30 minutes, contact Comms Channel support.
Activity & order status guideHow do I view service usage and CDRs?
Services → select service → Usage tab. The Usage Trends chart shows the last 30 days across Data, SMS, and Calls. The Usage Detail Records table below shows individual CDRs filterable by Origin, Destination, Date range, and Record Type (Call, SMS, Data, Travel Pack).
How do I port a number into CommsMobile?
Services → Create Service → Single Activation / Port-In. Select customer, assign user, choose SIM type, enter the number and specify Prepaid or Postpaid:
- Postpaid: requires the Account Reference Number (verify with losing carrier — invoices often show a billing number which may differ)
- Prepaid: requires the customer's Date of Birth
⚠️ Never submit duplicate port orders once a request is in progress — duplicates can cause the port to get stuck for 1–2 business days.
Port-in guide & demo videoHow do I cancel a service?
Services → select service → Advanced tab → Cancel Service. A red warning banner is shown. Click I Understand, Proceed to submit.
⚠️ Cancellation is permanent and irreversible. Always verify the correct service number first. If the customer wants to port their number out, the receiving carrier must initiate the port before cancellation — cancelling first releases the number permanently. Charges continue until the order reaches Complete. Plan disconnection is not prorated — no credit for remaining days.
How do I temporarily block calls, data, or SMS on a service?
On 2.0 services, the Features tab is currently view-only. Email helpdesk@commschannel.com.au with the service number and the change required.
Key points:
Key points:
- Triple Zero (000) remains available regardless of any block — mandated by ACMA
- The service continues to bill during a block
- Blocking SMS will prevent 2FA/OTP codes — confirm the customer understands this
- For a full billing suspension, raise a cancellation instead
How do I change service features on a 2.0 plan?
On 2.0 plans, Service > Features is currently view-only in the Comms Portal. This includes voicemail, call forwarding, Message2Text, and call barring. To enable or change any feature, email helpdesk@commschannel.com.au with the service number and the change required. This restriction is temporary — partner access is coming and will then match the current process.
SIMs & eSIMs
Are SIMs white labelled, and what do they cost?
SIM cards are plain white. Partners may invoice on their own letterhead but must reference CommsMobile product branding in all product description line items on marketing or financial documents.
- eSIM / Physical SIM: $3.75 once-off per service
- SIM delivery: $10
How do I perform a SIM swap in the portal?
Services → select service → Advanced tab → SIM Swap. Choose SIM type:
- Physical SIM: enter the 13-digit SIM number from the card packaging
- eSIM: no physical number needed — a digital profile is issued at $3.75 once-off
⚠️ eSIM profiles are one-time use — they cannot be reused on a new device. A new eSIM must be issued each time a device changes. After activation, the customer must set the new eSIM as the active/default SIM and remove the old profile from device settings. Performing a SIM swap while the customer is roaming with an active Travel Pack will stop the pack immediately.

What is Message2Text (voicemail-to-text)?
Available on CommsMobile 2.0 plans. The caller's message is transcribed and delivered as an SMS instead of audio voicemail. A service can only run one missed-call system at a time — enabling Message2Text disables voicemail.
To enable: email helpdesk@commschannel.com.au with the service number and a request to switch from voicemail to Message2Text.

Message2Text guide
How do I set up call forwarding on a 2.0 service?
Four types are available:
- Unconditional (GCFU): diverts every call — phone never rings
- No Reply (GCFNY): diverts if unanswered within a configurable timer (default 15 sec)
- Not Reachable (GCFNR): diverts when phone is off, in Airplane Mode, or out of coverage
- Busy (CFB): diverts when the line is already engaged
On 2.0 services, the Features tab is view-only. Email helpdesk@commschannel.com.au with the service number, the forwarding type, and the destination number in 61 format (e.g. 0455 555 555 → 61455555555; voicemail → 61101).

Roaming & Travel
What Travel Packs are available and what do they include?
Three Travel Pack options are available as bolt-ons to CommsMobile 2.0 Voice & Data plans. Travel Packs are not available on Data Only plans.
All packs include IR 67 IDD inclusion. If one allowance (calls/data/SMS) is exhausted, the other two remain available — the pack does not auto-renew just because one inclusion runs out.
| Pack | Data | Calls | SMS | Validity | Partner buy (ex GST) |
|---|---|---|---|---|---|
| 7-Day Travel Pack | 5 GB | 30 mins | 30 SMS | 7 days | $37 |
| 14-Day Travel Pack | 10 GB | 60 mins | 60 SMS | 14 days | $60 |
| 3GB Travel BizPack | 3 GB | 300 mins | 300 SMS | 3 days | $68 |
How do I activate a Travel Pack for a customer?
In the Comms Portal: Services → select service → Travel Packs tab.
Travel Pack partner guide
- Click Activate for immediate activation
- Click Schedule to set a future start and end date — the pack activates and deactivates automatically
⚠️ Travel Packs must be purchased through the portal — they cannot be added via any other channel. Only one pack can be active per service at a time. Performing a SIM swap or plan change while the customer is roaming cancels the pack immediately.
View all past packs in the Travel Pack History panel on the right of the Travel Packs tab.Travel Pack partner guide
How does a customer order or top up a Travel Pack while overseas?
PAYG roaming is disabled on CommsMobile 2.0 — customers must have a Travel Pack active to use their service overseas.
When a customer arrives at an international destination, they receive an SMS. They can order a Travel Pack or top-up via SMS reply. Roaming top-ups are also ordered via SMS.
Partners can also activate or schedule packs in advance via the Travel Packs tab in the Comms Portal before the customer travels — this is the recommended approach to ensure continuity.

Partners can also activate or schedule packs in advance via the Travel Packs tab in the Comms Portal before the customer travels — this is the recommended approach to ensure continuity.
⚠️ Without an active Travel Pack, the customer will have no roaming service. PAYG roaming is not available.
How do Travel Pack renewals, expiry, and billing work?
- Expiry: packs expire at midnight on the final day
- Auto-renewal: if the customer is still roaming at expiry, the pack auto-renews and charges apply
- Stops automatically when the service reconnects to the Telstra Wholesale network in Australia
- Unused resources do not carry forward on renewal — each renewal starts with a fresh allocation
- Usage alerts: SMS sent to the customer at 50%, 85%, and 100% of each allowance
- Spend notifications: SMS sent each time total roaming spend crosses a $100 threshold
- Billing starts from first roaming usage — charges stop when back in Australia
- Scheduled packs deactivate on the set end date regardless of location — roaming is also turned off at that time
- If one allowance (calls/data/SMS) is exhausted, the remaining two are still available
Which countries are covered by Travel Packs?
Austria, Belgium, Brazil, Bulgaria, Cambodia, Canada, Chile, China, Colombia, Croatia, Czechia, Denmark, Egypt, Estonia, Fiji, Finland, France, Germany, Greece, Guernsey, Hong Kong, Hungary, India, Indonesia, Ireland, Isle of Man, Israel, Italy, Japan, Kenya, Korea, Latvia, Lithuania, Luxembourg, Macao, Malaysia, Mexico, Nauru, Netherlands, New Zealand, Nigeria, North Macedonia, Norway, Papua New Guinea, Philippines, Poland, Portugal, Qatar, Romania, Russia, Samoa, Saudi Arabia, Singapore, Slovakia, Slovenia, South Africa, Spain, Sri Lanka, Sweden, Switzerland, Taiwan, Thailand, Tonga, Turkiye, UAE, United Kingdom, USA, Vanuatu, Vietnam.

Phone isn't connecting overseas — what should I check?
- Confirm a Travel Pack is active — PAYG roaming is disabled, no pack = no service overseas
- Confirm the destination is in the eligible country list
- Ensure Data Roaming and Roaming are ON in device settings
- Restart the phone to force a fresh network registration
- Go to Mobile Networks → Network Selection and manually select a local network
- Remove and reinsert SIM (if physical), or toggle Airplane Mode ON for 10 seconds then OFF
- Check no SIM swap or plan change was made recently — this cancels the Travel Pack

Troubleshooting
No signal, weak signal, or intermittent coverage — how do I troubleshoot?
Start with: restart, toggle Airplane Mode, check SIM seating, test SIM in another handset, confirm service is active, reset Network Settings, check CommsMobile Coverage Map and the Telstra Outage Page. If 1–2 bars consistently everywhere regardless of location, it is likely a handset antenna issue — arrange a device swap test.
Before escalating, collect: exact address/GPS, when the issue started, device and OS, signal shown (bars/4G/5G), indoors only or both, and whether other users in the same area are affected.
