Smud, we understand the convenience on being able to talk on the phone and use the hotspot at the same time. Did you check to see if you have advanced calling activated in your Android? If not, please go into settings and tap on advanced calling. Once done, you want to turn on and activate this feature. Once activated, you should be able to use the mobile hotspot while speaking on the phone. Please let us know if you were successful in doing so.
