VoIP over mobile data - Be aware that some mobile network operators prohibit or restrict the use of VoIP (Voice over Internet Protocol) over their network. They may prohibit the use of VoIP or impose additional fees and/or charges when using VoIP over their network. By using Groundwire over mobile data, you agree to abide by any restrictions your cellular carrier imposes and agree that Acrobits will not be held responsible for any charges, fees or liability imposed by your carrier for using Groundwire over their mobile data network.
