All the major carriers are going to these new "unlimited" plans and prior to today T-Mobile was the leader in value since they included unlimited messaging with their unlimited calling plans. Sprint just joined the affray and is now the value leader with their US$99.99 Simply Everything plan that includes unlimited calling, unlimited text messaging, unlimited GPS navigation, unlimited Sprint TV, unlimited Sprint Music, and unlimited data. It is easy, EVERYTHING is unlimited with Sprint's new plan that will be available tomorrow for new and existing customers.
For family plan customers, each additional line gets a US$5 discount so the second line would be US$94.99, a third line US$89.99 and so on up to five lines.
This plan is very attractive and if I used voice more than my data then I would definitely consider this plan with an EV-DO capable mobile phone. I wonder if the unlimited data includes unlimited tethering to laptops as well?
