The Modem will be a PLS8-E (EU Version) or PLS8-US (US Version). It provides GSM, LTE and GPS. SMS and voice is supported and tested, however it will fall back to 2G for voice on most networks. There's a CPU-GPIO controlled FET switch to disconnect the whole modem from power so you don't have to rely on the closed-source modem firmware. Also, there's a current sensor to detect if the modem is doing unwanted things. [1]

Antenna

The Antenova A10340 as seen here is listed with "Antennas Calvus SMD GSM850/ 900/1800/1900/WCDMA", although according to hns, the part in the actual retail units is the Antenova A10393 RUBRA, which is 7 less ;)

Carrier Compatibility

Main article: Carrier Compatibility

US

Look for a GSM network, like Tmobile or AT&T. (Verizon and Sprint use CDMA networks, which are incompatible with the Pyra modem.)

US MVNOs

There are smaller companies which use the Tmobile and AT&T networks (i.e. Virtual operators), but you'll have to look through for the GSM carriers with a BYOD policy.

Some that may allow use of a Pyra (none yet confirmed) include:

  • Cricket Wireless
  • Ting
  • MetroPCS
  • Simple Mobile

Australia

Australia requires the European Pyra Modem. See this Whirlpool Forum post for more details.

Europe

Pretty much everybody???
