You don't necessarily need the new Exede Wifi Modem if your transition to the Liberty plan.
The Exede WiFi Modem is available as an upgrade for an additional $5 a month in most areas. In some areas, the modem is available with Boost 25 — up to 25 Mbps download speeds. Where it’s available, the higher speeds can be added to your service for as low as $10/month. But remember, you must have the Exede WiFi Modem to get Boost 25 service.
To find out if the modem is available in your service area, visit Exede.com and type in your zip code.
