We have worked with the Key2roam Roaming Hub for several years. It is been a welcome complement to direct relationships for us, allowing swift launches and extra coverage that would have been difficult to achieve in-house. I particularly appreciate the hassle-free testing procedures, and the overall safe and carefree feeling provided by the service.

Kudos to the Key2roam hubbing team – always helpful and efficient, and consistently topping that off with friendliness. It is one thing to make it work – it’s another to make it a pleasure for customers.
