Important: check before activating another roaming pack
Each successful roaming pack activation incurs a pack charge. If roaming isn’t working after you activate a pack, contact Cmobile support before activating another. A new activation is a new purchase—it does not troubleshoot your connection.
Do I need to arrange roaming before travelling?
Yes. Contact Cmobile before leaving Australia to ensure international roaming is enabled on your C Blue service. Enabling roaming on your service and purchasing a roaming pack are separate steps.
How do I activate a roaming pack?
When you arrive in an eligible destination, send your chosen pack code by SMS to 179 from your Cmobile service. For example, send ROAM5 to activate the 5GB roaming pack.
Check the pack’s price, inclusions and validity before sending the code.
Is sending the activation SMS free?
The SMS to 179 is free, but the roaming pack you activate is charged to your account. Each successful activation incurs a separate pack charge.
What happens if I activate the same pack again?
Activating the same pack again before your current pack expires replaces the previous pack. Any unused inclusions in the previous pack are lost.
You will be charged for both successful activations, even if you did not use all the inclusions in the previous pack.
My roaming isn’t working. Should I activate another pack?
Please contact Cmobile support before activating another pack.
First, check your pack balance and confirm that your destination is covered. If you are having trouble with mobile data, check that mobile data and data roaming are enabled for your Cmobile SIM. If you use two SIMs, check that you have selected the correct SIM for mobile data.
Try restarting your phone. If the problem continues, contact us using Wi-Fi and tell us your country, phone model, activation code and any messages you received.
How do I check my roaming pack balance?
SMS BAL to 179 from your Cmobile service.
Why have I been charged for more than one roaming pack?
Each successful roaming pack activation is a separate purchase. Activating another pack does not cancel the charge for an earlier activation.
If you believe an activation or charge is incorrect, contact Cmobile support so we can review it.
What happens if I travel to a country not covered by the roaming pack?
Unfortunately you won’t be able to use roaming. In this case, we advise to purchase a local SIM.
I received a welcome message in an eligible roaming destination. Will I also get a product opt-in reminder message if I don’t opt in immediately? Can I opt in as and when I need it in a roaming country?
Yes, you can opt into the travel packs anytime while you are in an eligible country. The welcome message is sent when you first connect to the network and after 7 days if you remain connected to the same roaming network.
Will I be able to make Calls and SMS to other destinations covered in the packs? Yes, you can make calls and SMS to Australia and to countries covered in the pack.
Will I be able to receive calls and SMS If I don’t have a roaming pack on? You will be able to receive SMS but not calls, if you don’t have a roaming pack added. However, you can make calls/SMS if you have access to WiFi with WiFi calling.
