Explorers can now continue their voyages without worrying about their mobile phone bills. Wind Mobile has announced enhanced tariff plans for U. S. Roaming for Pay Before customers.

With one flat roaming rate across the U. S. and Canada, subscribers can look forward to saving more on roaming charges.

Following Toronto, Edmonton, Calgary, and Ottawa, Vancouver too has become the fifth Canadian city where Wind is available.

The company's `Chat,' `Always Talk,' and `Always Shout' plans are priced at $15, $35, and $45, respectively, and customers that sign up by June 30 will receive 50% off their wireless bill for the first six months. Wind is also promising that there will be no activation, system access, or 911 fees.

Perhaps the only downside to Wind's competitively-priced offering is the lack of subsidized handsets. Users that want a BlackBerry Bold 9700 Smartphone will have to shell out $450 to buy the device outright, rather than getting a discount in exchange for signing a contract.

Customers that are content with a more basic Huawei 1250 handset, however, can get away with spending just $70 on a phone.
