eSIM.Plus “as the Most Open Marketplace for Digital eSIM Cards

Latest iPhones’ support of eSIM kicks off a boom market for both Operators and OEMs. A couple of tech products like (eSIM+) have already been leading the way to exploit the Apple eSIM opportunity. eSIM+ provides an open marketplace that supports MNOs/MVNOs on quick eSIM solution deployment and offers a wide selection of electronic eSIM cards for eSIM-featured iPhone users.

eSIM+ is open to introducing new eSIM business opportunities for MNOs/MVNOs across the world to be part of its marketplace community and thus to give customers a wider choice of eSIM cards and greater freedom of selecting eSIM service. By providing standard SIM provisioning platform (SM-DP+ platform) which is fully compliant with GSMA standards for mobile Operators, eSIM+ assists them on quick deployment of eSIM commercial solutions for iPhone and other terminals with eUICC, enabling Operators, especially medium-and-small-sized MNOs and MVNOs, to have fair business opportunities on eSIM application and work across borders.

On the other end, the very straightforward web platform allows end-users an ultimate convenience to buy pay-as-you-go local connectivity and switch among multiple cellular data plans covering 60 countries and regions for their 2018 new iPhones without having to wait for a physical SIM card to be shipped. Users just need to simply scan a QR code to activate the eSIM over-the-air, without worrying if their local carriers support eSIM or not. The ways users switch between different cellular data are as easy as they switch between different channels with Netflix.

RedteaReady” in place to enable your massive IoT deployment scalability 


Are you looking for a sort of connectivity service for your devices that can enable guaranteed cellular network without any upfront costs? In addition, your devices no longer need to be customized in the factory for their destination. Ordering, building in and testing MNO specific SIM cards or profiles in the factory is no longer required as well. If your answer is yes, the connectivity-enabled modules powered by RedteaReady are right here to meet or exceed your expectations.

RedteaReady Service can solve the problem of the initial network connection in a practical way. Specifically, RedteaReady Service bundles eSIM capability together with a set of SIM profiles built-in, in order to provide connectivity as a service. We have implemented the service on Android, Linux, and one of the RTOS operating systems running with Qualcomm or MediaTek baseband processors, and we expect no major effort to port it to more other platforms and delivers global IoT Connectivity. The service uses a fixed set of the built-in SIM profiles without the need for personalization; therefore it is just a matter of integrating the service into the firmware for different module vendors and requires no modification in their manufacturing process, which makes it also possible to upgrade existing devices in the market over the air.


For the client which can be either the device OS or a 3rd-party application, RedteaReady Service provides an API to simply establish a guaranteed cellular network connection, with the amount of time to use and available data volume being the configurable parameters. The actual SIM profile used for the established connection will be chosen from the best available operators according to the current location, but the client doesn’t need to be concerned as it all happens automatically.

RedteaReady enables instant data connection from a device’s initial use, providing mobile subscription management throughout the device’s life cycle.

China dominating global IoT connections

China’s mobile operators continued to dominate the rapidly expanding global IoT market, accounting for 46 percent of cellular IoT connections in Q3 2017, Counterpoint Research reported.

The world’s leading operator in terms of IoT connections was China Mobile with a 32 percent share in the quarter (see chart below, click to enlarge). The operator’s connections grew 106 percent year-on-year as it is quickly transitioning to LTE IoT connections and is aggressively rolling out an NB-IoT network to take advantage of emerging IoT opportunities, Counterpoint Research said.

Global Cellular IoT Connection Share by Operator in 3Q 2017

China Unicom expanded IoT connections 39 percent from Q3 2016 and had a 9.4 percent market share in Q3 2017; rival China Telecom recorded 17 percent year-on-year growth to hold a 5 percent share.

Overall, the three increased IoT connections by 75 percent year-on-year.

The research company said worldwide cellular IoT connections increased 41 percent year-on-year in Q3 2017 after crossing the half-billion mark earlier in the year. At end-Q3, LTE connections accounted for more than half of cellular IoT connections and registered 84 per cent year-on-year growth.

Research director Peter Richardson noted cellular IoT connectivity had been modest so far but expects half a billion connections to be added by 2020.

Beyond China
Connections in Asia grew 64.2 percent year-on-year in Q3, with the region having a 57.2 percent share of global IoT connections. China accounts for 81 percent of Asian connections.

IoT connections in Japan and South Korea grew 15 percent and 25 percent year-on-year respectively: Japan held a 5 percent share of total Asia connections; South Korea 2 percent.

In terms of low power wide area (LPWA) development, South Korea is ahead of Japan. SK Telecom, LG Uplus, and KT commercialized their NB-IoT services in Q3 2017, Counterpoint Research said. KT also launched LTE-M in Q2 2017.

Outside China, Vodafone leads in cellular IoT connectivity globally posting 37 percent year-on-year growth and holding the second position with a 10.9 percent share. As of Q3 2017, Vodafone had launched NB-IoT in four countries including the Netherlands, Republic of Ireland, Czech Republic and Spain. The operator added commercial NB-IoT networks in Turkey and Australia in early Q4.




Global data traffic surges on India, China growth

Global mobile data traffic jumped 115 per cent year-on-year in Q3 2017, with India and China accounting for half of all traffic growth which hit a six-year high during the quarter.

India’s Reliance Jio carried more data traffic than any mobile operator globally within six months of launching its nationwide 4G network, but its disruptive impact on the market meant profitable traffic growth had been hard to find, Strategy Analytics reported.


Meanwhile, unlimited data plans in China have driven accelerated traffic growth, up 166 percent year-on-year in Q3, and have generated a healthy recovery in both service revenue and EBITDA, the research company said.

In Europe, Vodafone enjoyed healthy early traction for its zero-rated Passes, offering a more segmented and targeted approach to traffic and revenue stimulation. The operator had 8 million customers using Passes by the end of September, with a positive impact on ARPU and usage. It delivered 2.6-times growth in traffic in Europe over the last two years with near flat opex, highlighting the upside to more targeted traffic-stimulation strategies.

Phil Kendall, director of Strategy Analytics’ service provider group, said: “It is encouraging to see more success stories from operators using unlimited or zero-rated pricing to unlock growth in both revenue and profitability. The success of China Unicom’s unlimited plans and collaborations with local Internet giants highlights the importance of partnering with content providers to add value to data plans.”

Susan Welsh de Grimaldo, Strategy Analytics’ director of service provider strategies, noted operators need to evaluate both their market environment and customer segment priorities when contemplating unlimited plan options: “We applaud Vodafone’s strategy to focus on more targeted and segmented market offers in Europe, addressing discrete demand for messaging, music and video services within those segments.”

Average usage per SIM card increased from 0.7GB/month in Q3 2016 to 1.5GB/month in Q3 2017. Non-SMS data services now account for 55 per cent of all mobile service revenue globally.
