This is
interesting, because here in
Finland Telia has the cheapest
phone rates, as compared to our two other
mobile network providers, Sonera and Radiolinja. Many has changed their previous phone provider to Telia, to get lower prices. For example, to send a
SMS message, it costs 49 finnish pennies to send it via Telia, when it costs 99 pennies using Sonera or Radiolinja.
I haven't moved over to Telia myself, at least yet, although I have pondered about it many times.
