While we needed data support for all of our clients, it was a real challenge. As I used the WorldSIM Data roaming before and found it worthy, decided to get a first try with them. And, luckily got the router (I chose the Huawei) from them as well. Though we could assign ten devices with each router but I did not allow more than five. Guys applauded us for this new worthy service. Good job, WorldSIM.
