CDMA SIMs are compatible with HD devices only

When activating a CDMA network SIM, you must use an HD compatible device. This is due to changes made by RedPocket Mobile's underlying carrier for the CDMA network, effective 4/30/2019.

HD Voice is an advanced calling feature that works only on the LTE network. It provides clearer call quality. 

Is this change limited to RedPocket Mobile?

No. This change effects all MVNOs using the same underlying carrier as the RedPocket CDMA network.

How do I know if my device is capable of HD voice?

To check if a phone is capable of HD voice, check the settings for the option to enable Advanced Calling or VoLTE. If the device does not support Advanced Calling/VoLTE, it is likely not HD Compatible on the CDMA network.

What options do I have for my device if it is not HD voice compatible?

LTE compatible devices may work on one of RedPocket's other network options, like the GSMA network, with the insertion and activation of a GSMA SIM.

Who is affected

Customers who activated service before 4/30/2019 are not affected by this change. This includes CDMA customers using devices that do not support HD Voice.
