Mobile SIM network redundancy – dual SIM Cmobile

The recent nationwide Optus network outage really underlined just how reliant we are on being connected these days. Businesses were unable to take payments via EFTPOS, ATMs were offline, security cameras inoperable, Train services stopped, and even automated gates were rendered useless. Businesses relying on the Optus network were basically crippled for the duration of the outage.

On a personal level, vulnerable or aged family members were uncontactable, services like Uber were not able to be accessed, and the simple annoyance of not being able to communicate with friends and family were all impacts of the Optus outage.

Imagine if you were simply able to switch to a different network and continue to operate as normal with no impact on your business or life…Well, you can!
Cmobile is one of the few mobile carriers in Australia that has access to more than one network. This puts Cmobile in the unique position to be able to offer “network redundancy” to all of our customers, business and consumers.

Simply connect to one of our great value C Blue plans on the Telstra network, and for an extra $5 per month, we’ll supply you a C Red SIM, which is carried on the Vodafone network. This means you have peace of mind that if the worst happens, your business or lifestyle won’t be impacted. You may even find your C Blue plan with C Red network redundancy works out cheaper than you are paying now for one SIM!

If you have a dual SIM phone, you can have both SIMs in your phone. You are now able to switch to your backup SIM at the touch of a button. If your device only takes one SIM, you can carry the SIM in your wallet or purse, or even keep it in your desk in your office. The SIM is “plug and play” and ready to go as soon as you are. Bring your EFTPOS machine back online in minutes! All for just $5 per month.

Head to today, and check out all of our great value plans. They all come with no lock-in contracts and our all-Australian expert customer care.

Cmobile. The Choice is Clear!

Telstra 3G mobile network exit

Telstra is upgrading the mobile network to deliver a better experience for all users. As part of these improvements, the current 3G network will be retired and all users will move to the more modern 4G and 5G network. This will impact Cmobile customers who have a C Blue – Telstra network plan.

The current Telstra 3G mobile network (850Mhz band) will be retired on 30 June 2024. There will be no interruption to 3G services or network coverage prior to this date. After 30 June 2024, the mobile network will only support 4G and 5G devices. Note, your 4G device will need to support Voice over LTE (VoLTE) to support voice calls. Most modern smartphones support VoLTE and WiFi calling which uses digital packet technology to route voice traffic and transmit data.

If you have a device that only supports 3G or it is a non-VoLTE capable 4G mobile device, it will cease to operate on the Telstra network after 30 June 2024. You will need to upgrade to a new device that supports 4G VoLTE and 5G networks to maintain your service.

If you are unsure if your device supports 4G or 5G, please contact us at or call us on 1300 545 000 and we will be happy to help you.

Frequently asked questions

I have been told my device will stop working, why?
Telstra is improving the mobile network to deliver a better experience and move to a more modern, faster and energy efficient network. To do that, the old 3G network will need to be retired to support modern 4G and 5G technology. Devices that are 3G-only or not compatible with 4G will stop working once the 3G network closes. To maintain your service, you will need to upgrade your device to a suitable 4G or 5G device.

What do I need to do?
You must upgrade to a 4G and/or 5G compatible device to stay connected to your service. When you upgrade, be sure to confirm the device is compatible with the Telstra 4G and 5G networks by checking the specifications on the manufacturers website. If you are not sure you can always contact us to confirm.

How can I tell if my device is affected?
The best way to find out is to search for the specifications of the device online, visit the manufacturer’s website or ask the retailer where you purchased the device. You can also contact us for help.

Do I need a new SIM card if I upgrade my device?
Our SIM cards already work on the 4G and 5G network. You will only need to replace your SIM if the size does not fit in your new device. If this is the case, please call us to arrange for a replacement SIM card.

My device is 4G, but I received a notification about the 3G exit. Am I impacted?
If you received a notification about the 3G exit from us, then you are most likely impacted by the 3G exit. It could be that your 4G device is not VoLTE (or 4G voice) capable. Your 4G device will need to support VoLTE to make and receive voice calls once the 3G exit occurs.

What is VoLTE?
VoLTE is the next step in voice calling technology for mobile phones, enabling users to make voice calls over the 4G network. This means clearer calls and faster connection times. Users who have compatible devices will already have access to VoLTE and WiFI calling. When the 3G network closes, VoLTE will be required to make and receive phone calls.

Data Pooling for Business Mobile

Data pooling for business mobile is a feature on our C Blue plans delivered on the Telstra mobile network. Data pooling allows a business with many mobile services to share or pool the data across all their services. For example, if a business has 5 mobile plans with 20GB of data each, then a data pool of 100GB (5 x 20GB) will be available across those 5 mobile plans.

Data pooling can be applied to both handset and data SIM plans across the entire mobile fleet of any size.

Databank for C Blue plans

Introducing Databank up to 500GB

Cmobile now offers databank on all C Blue mobile handset plans delivered on the Telstra mobile network. This means you will be able to save any unused data rather than lose it.

What is Databank?

Databank allows you to save (or bank) any unused data in the month. For example, if you have 20GB in your mobile plan but you only use 10GB in the month, you will bank the remaining 10GB. This means if you ever use all your included data during the month, instead of having to purchase additional data you will move to your databank to consume any data you have previously saved, or banked.

How big is my databank?

Currently, you can save up to 500GB of unused data.

How do I know how much data is in my databank?

Simply dial *159# on your phone and press the send button as if you making a call. Your phone will then display your current data remaining in your plan and your databank balance.

What happens if I leave Cmobile or change plans?

If you leave Cmobile, either to a competitor network or even to one of our C Red (Vodafone network) plans, you will lose any data saved in your databank. Additionally, if you downgrade a plan (e.g. move from your current plan to a lower priced plan) you will also lose any data accumulated in your databank. As long as you stay on the same priced plan or upgrade to a higher value plan, you will continue to save your databank up to the maximum 500GB.
