WTL proposes a national roaming solution called Vivada to address rural connectivity challenges. It involves regulators assigning spectrum to a neutral party to build a GSM network in unconnected rural areas using universal service funds. This network would then be offered to all mobile network operators as a national roaming network, allowing them to pay as they use it. Key advantages are reduced capex, quicker coverage expansion, more transparent funding use, and a sustainable pay-as-you-use model.

Rural Connectivity Current Status
● GSM spectrum owned by MNOs but no incentive to investing in lower
profit regions.
● Regulators sanctions have not forced operators to go there either
● Hard to direct Universal Service Provisioning Funds for the intended
purpose.
● Despite good intentions, the remote areas remain unconnected!
The Way Forward: National Roaming Solution
● Regulators / Governments assign GSM frequency for unconnected
villages for public good in defined (remote) geographical areas
● This Frequency assigned to Neutral party who builds the GSM network
under USF
● Neutral party offer s network as national roaming network to all MNOs
in the country
● Mobile operators pay as they use the network
