• Expands coverage outside of carrier’s network, both domestic and international, while maintaining use of existing mobile number

• Reduces carrier’s need for femtocell and small cell deployments

• Reduces carrier’s cost on unlimited calling/SMS/MMS plans without reducing revenue

• Reduces roaming fees to carrier & subscriber where applicable

• Reduces traffic demand on existing spectrum



SpectrumMax Wi-Fi Calling Benefits

o all provide rich messaging over Cellular & Wi-Fi but w/o mobile number identity

o OTT Messaging disintermediates the mobile carrier, generatingno incremental revenue, yet increasing data traffic demand
