Our history -
Where we come from

Our own story begins with the founding of whatever mobile GmbH in 2002. As a provider of secure and technically reliable SMS applications such as mTAN and 2-factor authentication, the Hamburg-based company is making a name for itself across industries. With its more than 70 employees and the agile approach in its own software development, whatever mobile works for companies such as Siemens, Postbank and Paypal and quickly grows to become the largest German messaging provider.

With the founding of wherever SIM GmbH, the first step is taken into a future market that is just developing: multi-network SIM cards / M2M SIM cards. In doing so, wherever SIM benefits from its many years of experience in the mobile communications market and its established relationships with network operators. As before with SMS, the company focuses on an existing network operator product and improves it, based on the actual requirements and needs of enterprise customers.

In 2017, the SMS messaging business of whatever mobile GmbH will be acquired by LINK Mobility Group. wherever SIM GmbH continues independently and has since successfully implemented more than 1,000 projects worldwide.
