Googling “SL3010T” gives no hits at Sierra Wireless;

It does give this: [apps.richardsonrfpd.com/Mktg/Sie … eries.html](http://apps.richardsonrfpd.com/Mktg/SierraWirelessAirPrimeSLSeries.html) - but nothing there has the ‘T’ suffix…

😕

Hi Awneil,

it does support Open AT application framework… i looked in PTS… it says … “Dual-band support for both the 800 MHz cellular and 1.9 GHz PCS bands”… ‘T’ means that it supports Open AT… what i found from PTS is that it has Support for IS-95A/B and CDMA 1X Release 0/A. Need to confirm this… will get back soon…

Thanks
