From
globalcomsatphone.com: "The +1 Access service is similar in
concept to two-stage but doesn't require any user intervention. Each +1 number is directly mapped in the switch to an accompanying 8816 number. When a call is received via +1, the system identifies the correct MSISDN and routes the call to the Iridium user. The process is seamless, but there will be a slight delay prior to call connection - as is currently experienced with two stages...Subscribers can manage their call costs and caller access by choosing to distribute their 8816 phone number or their +1 phone number. Customer satisfaction will increase as callers are able to avoid the high PSTN termination charges associated with direct dialing."
Other outfits also make a distinction between 2-stage and a direct +1 number. Although it would be nice, as i also operate my own business, it really is unnecessary.
SMS is huge for me, and yes you're right most providers have free incoming texts, i use a Zurich based
weather service for my expeditions and I can finally ditch all the
gear associated with getting
email. Now i can get my
weather forecasts for free over SMS, so crucial.
Apparently Iridium is restructuring their costs because of the next-gen
satellite they are launching, which will be online in 2015. Hopefully they don't release any next-gen handsets making my poor (and expensive) 9575 obsolete.
