Get online support
I've purchased a TPG sim and am trying to get it to work with my Moto G4 Plus running Android 8.1.0 (https://www.gsmarena.com/motorola_moto_g4_plus-8050.php). I'm not able to make or receive any calls, however I'm able to send and receive text messages.
This model appears to have VoLTE capability. See https://forums.lenovo.com/t5/Moto-G4-Moto-G4-Plus-Moto-G4-Play/Does-moto-g4-plus-support-volte/m-p/3...
However, the model is not listed in TPG's or Vodafone's list of supported devices.
TPG: https://community.tpg.com.au/t5/SIM-Only-Plans/TPG-Mobile-Voice-over-LTE-VoLTE/td-p/109634
Vodafone: https://www.vodafone.com.au/support/network/volte?title=android&accordion-id=motorola
If the reason for not being able to make or receive calls is only due to the phone not being on the allowed list, can I please request for this phone to be added to the supported list of models?
The model appears to support all 3 4G bands listed here: https://www.vodafone.com.au/support/network/4g-network (2100MHz, 1800MHz, 850MHz)
