A 20th century way to solve a 21st century problem
The *requirement* isn't dual-SIM. That's the solution. Or at least, that's one solution.
The *requirement* is for a single handset to have two mobile numbers, each supporting both calls and SMS, each supporting their own contact directory, and each being billed separately. Earlier attempts at this using VoIP clients etc weren't fit for purpose, since most didn't support SMS, and all of them required a good wifi or 4G coverage that rendered them unfit for purpose as a business mobile device.
A much more cost-effective solution to the requirement isn't to wait for manufacturers to build a limited set of dual-SIM phones, but instead to leverage cloud services to enable this second number. Services such as 'smartnumbers mobile' provides a second GSM mobile number on any IOS or Android smartphone today. Choose your device, choose your number and hey presto, off you go. And unlike earlier attempts at this, the smartnumber mobile services are full GSM with no requirement for VoIP. Furthermore, if you want to keep your existing business and personal mobile numbers then you can port these numbers into the smartnumbers mobile service.
With today's focus on all-things Cloud, do the analysts really think that hardware is the answer to what are user/functionality requirements ?
There's gotta be a smarter way....
