China Mobile and KPN have claimed the first successful trial of international, IMS-based VoLTE (Voice over LTE) roaming between operators. The service is based on technology developed by KPN subsidiary and mobile operator solutions provider iBasis.
KPN’s carrier services operation, iBasis, this week scored an LTE signalling exchange and roaming contract from Claro Peru, a subsidiary of America Movil.
From the summer, Vodafone claims it will offer LTE roaming to more countries than any other mobile operator and it will not charge a premium for such services.
Only around a fifth of respondents to the Telecoms.com Intelligence Industry Survey 2014 strongly believe that mobile operators are justified in charging LTE roaming at a premium to other roaming services. But even fewer expect that specialist roaming providers will come to dominate the retail roaming market, suggesting that mobile operators will continue to derive vital revenues from roaming, despite pressure on tariffs from competition and regulation.
