For many companies, an unlocked, unprovisioned phone makes good financial and support sense. Meanwhile, the federal government is scrutinizing deals that lock users into buying a specific phone only from a specific carrier (think iPhone and AT&T). All of this means that unprovisioned smartphones may be more widely available in the future. eWEEK Labs examines the reasons for and against going with an unprovisioned phone, and provides a list of possibilities should the latter be right for your company.
Many companies do just fine with the standard, off-the-shelf smartphones
that can be picked up from any carrier, but many need something different. For
this reason, unprovisioned-or unlocked-devices are gaining interest, if not
widespread availability, at this time.
One thing you should know is that unprovisioned smartphones are only a
subset of unlocked phones. It is possible to buy an unlocked phone that is
provisioned for a specific carrier but that can have its provisioning changed
to some other carrier. Other unlocked smartphones are completely unprovisioned.
Provisioning a phone really means telling the phone what network it should
be running on for data access. When you put a SIM
card into a GSM smartphone, that provisions the phone for a specific voice
carrier. However, you also need to tell the phone the addresses of the network
routers it should use, how and where it should get its IP address, and the
like. You may also need to tell the device what to do if it finds multiple
voice networks and multiple data networks available.
Provisioning is normally done through a series of menu choices in the
phone's system settings. However, with some phones, it's possible to create a
script that will perform the task for you. In many cases, the carriers will
provide the scripts for the most commonly used smartphones. T-Mobile, for
example, keeps a library of smartphone provisioning scripts on its Website.
The availability of unlocked phones is likely to increase along with greater
scrutiny into deals between carriers and device makers that lock customers into
A primary example of a deal being examined by the Federal Communications
Commission is the one in which Apple's iPhone is available in the United
States only from AT&T. This forces U.S.
users who want to go with another carrier to either unlock the AT&T phone
(and risk having it relocked by Apple when the phone is connected to iTunes) or
to import an iPhone from Germany
to get a T-Mobile version.
Congress also has its eye on these kinds of deals and, at the very least,
could make such exclusive deals easier to bypass. This may mean that carriers
may soon be willing to provide unlocked versions of devices that currently are
not available in that form.
There are currently several smartphones that are available as unlocked
The Palm Pro, for example, is available only as an unlocked device. Its 3G
features work only with AT&T in the United
States, although it can be provisioned to
work with most 3G carriers elsewhere. Likewise HP's Windows Mobile 6.1-based iPaq
910c is available only as an unprovisioned, unlocked smartphone. You'll have to
get a SIM card from your carrier and then
set up the phone manually. In addition, Nokia makes several of its smartphones
available as unlocked devices.
You can also buy devices in an unlocked form even if their manufacturers
don't provide them that way in the United States,
but there may be risk. For example, you can buy unlocked BlackBerrys even
though Research In Motion doesn't sell them that way, but generally these
phones are sold by third parties without a warranty.
