Just following back up on this since CricKet is pushing this advisory SMS out to customers right now:
3G Network Shutdown
Cricket Wireless is committed to supporting the growth of mobile Internet and providing the best customer experience. As a result, Cricket plans to end service on 3G (UMTS) wireless networks by February 2022. This will allow additional space on Cricket’s mobile Internet network. At that time, Cricket will require all customers to use a compatible HD Voice device for voice-and-data plans or an LTE-capable data-only device for data-only plans. If you currently have Cricket service on an HD Voice-capable device or an LTE-capable data-only device that is compatible with the Cricket network, you will not be impacted by these network changes.
Starting January 19, 2021, Cricket will no longer activate devices that customers bring to Cricket if the device is not HD Voice-capable or an LTE-capable data-only device compatible with the Cricket network.
Current customers:
- Without an HD Voice-capable device need to upgrade to a compatible device by February 2022 and should not move their SIM card to another non-HD Voice-capable device.
- Who move their SIM card to a device that is not HD Voice-capable will experience an interruption in service. Important: Moving the SIM card back to a non-HD Voice-capable device will not restore service, even if you previously had service on that device. To restore service, you must move the SIM card to an HD Voice-capable device that is compatible with the Cricket network.
- To determine network compatibility, check your IMEI.
New customers attempting to activate service:
- Can purchase a device sold by Cricket, or
- Can bring their own HD Voice-capable device, or an LTE-capable data-only device, compatible with the Cricket network.
To determine if your device is compatible with Cricket’s network, check your IMEI.
Checking my IMEI/MEID:
That being said, I have not experienced HD Voice/VoLTE/VoWiFi working on my Android 9 handset, and I’m a bit reticent to SIM-swap to my testing Android 11 one currently to see if they’ve finally turned it on network-wide.
So, from my reading, all ATT/CricKet TeraCube One customers should be fine with the upcoming network change, so that’s lovely.
