The GRX experts

GRX is used globally to transport mobile data between MNOs. No one knows GRX better than us – we invented it and have been at the forefront of its development ever since.

Today, we provide direct and seamless connections between mobile operators ranging from emerging markets to LTE-enabled technology leaders.

Burstable billing plans

European regulations mean that users in the EU can use their home data bundle in other EU countries without extra cost. For MNOs, this means major seasonal bursts in mobile data – we estimate it can triple normal traffic. Our GRX Burst plans help operators meet the seasonal demand without paying for unneeded capacity during the rest of the year.
