I e-mailed Resmed and the following is the reply I received :
Wed., May 20 at 1:48 p.m.
Thank you for contacting ResMed.
The data connectivity issue you are experiencing may be related to the recent telecommunication companies’ decision to shut down their CDMA networks in your area. Some of ResMed’s Air10 devices communicate data wirelessly using the CDMA networks in Canada and as a result of the telecommunication companies’ decision ResMed cannot guarantee wireless connectivity for Air10 devices communicating on CDMA networks.
Please note your Air10 device will continue to function as intended. The performance of your device will not be affected by a lack of wireless connectivity. Additionally, the data on your Air10 device will still be accessible through SD card technology if it is requested by your care provider. You will find simplified instructions on how to download and email data from your Air10 device’s SD card at: ResMed.com/sdcardfaq.
If you are currently using myAir, our online patient support program, you may notice that your myAir score and data will no longer be available once the CDMA network is shut down. You can continue to use myAir to access videos and guides about your equipment and treatment.
If you have any questions regarding this notification, please contact your care provider.
We apologize for any inconvenience arising from the decision by the telecommunication companies.
Thank you,
ResMed Customer Care
