Our tests with two of the top providers of roaming sims showed them to be no better or worse than standard sims on the same network. The misconception is that they operate on several networks when in reality they lock and stay with the first network they find, only dropping that connection in a complete absence of radio signal.
This is ideal if you’re going offshore or in the wilds of the highlands but in the urban environment where most companies operate, a total signal loss hardly ever occurs due to the relatively high number of masts. So you often end up with a flaky signal that’s just not good enough to maintain a reliable Internet connection.
Reliance on a radio signal is the fly in the ointment for this approach because ironically the radio transmitter section is probably the most robust component in the entire network. Network and routing problems are far more common but don’t kill the signal so it’s entirely possible to have full signal but no data connection. And given this, routing your data via an overseas network only increases the number of potential points of failure!
We took our findings back to both the providers who then both agreed that the roaming sim had little to offer the taxi trade.
But if you believe that Jack and his beanstalk are real, then go out and get some magic beans.
