Think Mobile is an atrocious company to deal with.
Their plans might seen good value, but their definition of "unlimited calls" is much, much lower than you might think.
They will bar your service when they feel like it, citing violations of their Fair Use Policy, and won't hesitate in barring your service until you get the TIO involved.
