Cellular Modem (Juno 3D Only) | |
Type | *HSDPA 3.5G cellular modem (Quad-band GSM/GPRS and Tri-band WCDMA 3.5G) |
*The cellular capability of the Juno 3D handheld is powered by a Cinterion (Siemens) HC25 module. The Juno 3D will operate in 2.5G mode on GPRS and EDGE networks supporting any of the 850/900/1800/1900 MHz bands or in 3G/3.5G mode on supported 3G and HSDPA networks supporting any of the 850/1900/2100 MHz bands. The Juno series handhelds will not operate on legacy CDMA networks. The Juno SC handheld has PTCRB certification, and can be operated license-free on networks which accept these cellular certifications, and which do not require explicit certification by the network carrier. Examples are the T-Mobile and Virgin Wireless networks in the USA, and the Vodafone networks in Europe. Please note the Juno 3D does not have AT&T certification, and cannot therefore be used on the AT&T network in the USA, or the Rogers network in Canada.
