Hello everyone, I am currently using a Nexus 4 running stock Android 5.1.1. I am also on the $15 Unlimited Messaging Base Plan, with an active Talk Booster Add-on and a positive Top-Up balance. I am unable to receive any incoming calls. I can place outgoing calls just fine, but when others try to call me, they either get "the number cannot be completed as dialed," or "the call cannot be completed due to insufficient balance." As this is my primary phone, this is a big concern. Any help on this would be greatly appreciated. Thanks!
