Machina Research estimates that there are now 350 million cellular based connections worldwide, and this will grow to 1.3 billion over the next five years. However, the proportion of M2M connections accounted for by roaming is growing even faster. As a global provider of roaming services including billing and clearing to network operators, Starhome Mach is able to determine that the number of roaming registrations that can be attributed to M2M devices increased by 100% last year to reach 7% of all roamers. The rate of growth is such that it is entirely possible that there will be as many machines as people roaming by 2020.
