The T-mobile Personal Cellspot that was announced last month is finally coming available. Starting September 24, you’ll be able to pick one up in store, or order online, and pay only a $25 deposit. But(!) if you call T-mobile technical support they will process your order now and waive the $25 deposit.
It’s worth noting that you don’t own the Cellspot, you’re borrowing it while you have T-mobile service.
