I was doing some research on roaming costs.
I visited this page, where I read as follows:
Same Countries, Different Roaming Rates
Between Spark and Vodafone, there are different roaming rates for the same country. For example, if you stop off in Dubai for five days, and use 1 GB of data, with a Spark roaming plan you will pay $20 or $15, depending on the plan you pick. If you are with Vodafone, which does not offer the UAE in its standard roaming plan, you would pay $250 (as it sells 200 MB of data for $50 as part of its 'Data Angel Overseas' package). But if you go prepay, Vodafone would charge an astonishing $10,000 for 1 GB.
Is this actually true? It seems...excessive.
