For operators, offering LTE roaming comes with both potential risks and rewards. That services have been slow to materialize has more to do with commercial considerations rather than network complexities, Mark Newman, chief research officer at Informa Telecoms & Media, said earlier this year.
"Operators are concerned that if they don't get the retail pricing structure right, LTE roaming could end up cannibalizing their revenue from voice and SMS roaming," he said.
So far, 213 LTE networks have been commercially launched in 81 countries, including 113 networks in the past 12 months, according to the latest figures from the GSA (Global mobile Suppliers Association).
