Mobile connections (GSM/GPRS/3G/UMTS)
More and more people are using Your Freedom via
mobile connectons (GSM, GPRS, UMTS, 3G services). While Your Freedom
works across mobile connections too (though not yet on mobile devices),
there are some restrictions that need your consideration. This page
tries to answer the most common questions and tries to point out the
caveats.
If you are from Nigeria or another country where people usually connect to the Internet through phone networks then this page is for you!
Will Your Freedom replace my Internet connection?
No. Your Freedom can only work across an existing
Internet connection. Your Freedom is meant to remove restrictions that
your current Internet connection imposes on you, it is not meant to
replace it completely. We are not a reseller of some network operator or
the like, and we do not operate any mobile networks.
Do you have your own SIM cards?
No. We are not a local loop provider, we do not
operate access connections and we do not operate mobile networks, nor
are we a reseller of any mobile network provider.
What modem/phone do you recommend?
You should ask your mobile network provider, not
us (and you probably shouldn't mention "Your Freedom" when you do). We
just provide a service on top. You wouldn't ask us about the right type
of keyboard or a recommendation of a screen either.
Will Your Freedom let me browse for free?
Maybe. We do offer a free service (and it's of
course free as the name suggests) but unless your mobile provider's
network has holes that permit the YF client to connect to the server
without paying for the service you still need to pay your mobile
provider for data access. If you think you can use the Internet for free
through us then you may be right with some providers; check out blogs
and forums on the Internet. We've seen public wireless access points
that could be fooled and there might be broken WAP gateways.
In short, we have found that in some cases the answer is "yes". See the country information pages.
Please keep in mind though that this is a side-effect of Your Freedom's
intention of bypassing censorship, not an intentional, guaranteed
property of our service. If it works, fine.
Will Your Freedom make my mobile Internet connection faster?
We cannot make your connection faster than it
physically is, but we may be able to use it more efficiently, for
example if your provider routes traffic in a sub-optimal way. More
likely, however, the connection will be slightly slower because of the
protocol overhead.
If your uploads and downloads hit the physical limit
of your Internet connection, there is nothing Your Freedom can do about
this. If you are connecting through a GSM network your typical speed
will be around 50 kbit/s and the round trip time will be around 700 ms,
with Your Freedom as well as without. UMTS/3G generally provides higher
data rates and faster response times (a typical rate is 250 kbit/s and a
typical round trip time is 200 ms, but your provider and/or mobile
device may have other limitations). You'll find more details further
down the page.
You may have heard that Your Freedom actually
improves responsiveness for some. The only thing Your Freedom can do
something about is sub-optimal routing by your provider. If your
provider has good connectivity to our servers but bad connectivity to
(for example) gaming servers, using Your Freedom may actually improve
your connection to these servers.
Let me tell you a bit about mobile Internet connections. No matter what your provider says, it's not
a real Internet connection (i.e. it is not using TCP/IP). Mobile
networks emulate some protocols from the TCP/IP protocol suite, among
them TCP, UDP and ICMP. They only do it to a certain degree and in most
cases the emulation is not entirely transparent (for example, many
providers reduce the quality of JPEG images when browsing Internet web
pages to conserve bandwidth). To avoid applications running into
timeouts all the time, many signal a successful TCP SYN-SYNACK-ACK
handshake even though an end-to-end connection hasn't been established
yet. They are not doing it to pester you, but to ensure the best
possible service over a network that is not very well suited for the
TCP/IP protocol suite. This may all sound very technical to you but the
bottom line is easy to understand: it's not a true Internet connection
and you should not expect it to do miracles. You can use Your Freedom to
turn the emulated Internet connection into a real one (from the
protocol perspective) and this may improve your "Internet experience",
but trust me -- it won't be faster. It might work better though.
