ABOUT US

Launched in 2009, Annatel is an Israeli telecommunication company.

From 2019, we built and now operate and maintain our own full mobile core network (2G, 3G and 4G) to operate as a full MVNO.

As we went through the building process of a core network, we decided to work with many great vendors. However, we built many parts of our network ourselves because we were not able to find solutions we believed were light, flexible, affordable and innovative enough to allow us to continue to offer what we are striving for : innovation. As we mainly develop our products for our own use, we are our first and most demanding customers. Our products are meant to be light, flexible, affordable and easy to implement in different core networks. In 2020, we decided to offer some of our in house developed products to other operators who are looking for what we looked for in the past. The first product we are offering is a SIM OTA platform.
