Find new mobile opportunities with a top SIM provider

According to the GSMA, global SIM subscribers accounted for over 5 billion people in 2019 and is expected to reach nearly 6 billion by 2025. Yet despite this and the growth of mobile data, network operators’ ARPU (Average Revenue Per User) remains under pressure. In the midst of growth sectors created by emerging technologies such as eSIM and 5G still in their early stages, how can operators successfully drive revenue in the short to mid-term?

Many network operators are increasingly looking to partner with a regional SIM provider who does everything in-house rather than older multinational providers who rely on third-party suppliers often far from the market which, with time and distance, severely impacts their supply chain and associated costs.

As a world top 10 SIM card manufacturer, we adopt a highly cost-efficient, integrated approach. From design and SIM card printing to technical support, SIM data personalisation, to SIM packaging, fulfilment and logistics, we provide a full SIM solution all under one roof. This removes unnecessary costs throughout the supply chain and allows you to get the most competitive prices at the quickest delivery times.
