I know lots of folks who are happy with Clear or Sprint WiMAX service, and I applaud them for their no-contract Day Pass option. In fact, I wouldn’t hesitate to suggest that others go the same route I did: Buy a Clear modem on eBay and pay $10 per day whenever you need connectivity. But I strongly discourage readers from signing up for a long-term contract with Clear. Sprint subscribers will likely be upgraded to LTE eventually, but the future of Clear is very, very cloudy.
