Answer 2

I am going to guess that you mean one of those PC Card for laptops and notebooks, that calls the cellphone data network so you can get online from almost anywhere there's digital phone signal.

Contact your cellphone vendor's factory store. Normal vendors do not stock or even know about this kind of stuff. Data plan and cost will vary. See your local factory store for details. Member FDIC (just kidding!)

What is 3G HSDPA?
High-Speed Downlink Packet Access or HSDPA is a new mobile data protocol and is sometimes referred to as a 3.5G technology.

The absolute maximum theoretical speeds are:

* Downlink: 1.8 Mbps
* Uplink: 128 Kbps

What is needed to access the 3G HSDPA Broadband network?
The latest HSDPA data card that can be used with a Vodacom 3G contract or with a 3G/MyMeg Bolt-on.

Vodacom is currently introducing the new HSDPA enabled Vodafone Mobile Connect Card - the Option Nozomi. The Novatel U740 and Huawei E620 data cards have also been approved on the Vodacom network.

How much does it cost?
Vodacom now offers the lowest data tariffs to its Contract, as well as Prepaid and Top Up customers.

Are the current 3G Vodafone Mobile Connect Cards compatible with HSDPA?
No, unfortunately the current cards cannot be upgraded to support HSDPA. Customers will need to purchase the new HSDPA enabled Vodafone Mobile Connect cards.

Why can the current Vodafone Mobile Connect cards not be upgraded?
All current Mobile Connect cards do not have the physical capability to be used on the higher speed, so upgrading the software won't help.

Now that we will be supplying 3G HSDPA cards, will the 3G cards still be available?
Yes, the 3G Vodafone Mobile Connect cards will still be available. Different deals will be structured between 3G and 3G HSDPA cards. The 3G HSDPA cards will obviously be more expensive than the 3G cards when purchased for cash.

Can any handsets make use of the 3G HSDPA Network?
Current 3G handsets are not compatible however new HSDPA enabled handsets are likely to only become available later this year.

Are the 3G Routers compatible with the 3G HSDPA cards?
Yes the existing Linksys Routers are compatible however a firmware upgrade to the router will have to be done. Click here for downloads.

Where can the 3G HSDPA Broadband Network be accessed?
All 3G enabled base stations have been upgraded to also support HSDPA, however the coverage is not identical as the HSDPA network is more sensitive to external influences such as indoor coverage, topography and weather conditions. For more information on where 3G HSDPA coverage is available, click here.

Can customers roam with 3G HSDPA?
Yes, roaming will be available initially in Germany, Austria and Portugal. It must be noted however that it is very costly and potentially more so than 3G due to the increased ability to download more data. Current 3G data roaming rates apply.

Does the 3G HSDPA card look different to the current 3G data cards?
No, the Option Nozomi, HSDPA card is identical to the Option Quad lite and Option Fusion cards. To identify your card, look at the serial number on the back of the card. These are the prefixes to the various cards.

Card Name Serial Prefix HSDPA Enabled
Option Colt CL No
Option Quad-lite QL No
Option Fusion RC No
Option Nozomi NZ Yes

With regards to the Novatel U740, it too is identical to the Novatel U630 but the main sticker on the top of the card will denote that it is an HSDPA card

Both the Option and Novatel HSDPA cards will have the 3G Broadband logo on the top of the card.

What speeds can be attained on the 3G HSDPA Broadband Network?
Under perfect conditions one would get speeds of up to 1.8 Mbps, but expect to see speeds of between 400 Kbps and 800 Kbps with peaks of approximately 1.2 Mbps.

If there is no HSDPA signal will I be able to use 3G and GPRS?
Yes, when the signal drops off you will be able to access the 3G, Edge and GPRS network in the same manner as with the 3G Data cards.

When I am connected, how will I know that I am on 3G HSDPA and not 3G?
When you are connected via 3G HSDPA, you will seamlessly move between HSDPA and 3G, as they use the same network infrastructure. The flashing lights will however indicate which bearer you are using - 1 flash for GPRS, 2 for 3G and 3 for HSDPA. (This applies to the Option Nozomi card only).

Why am I getting 3G like speeds whilst "connected" to HSDPA?
The HSDPA/3G network has the intelligence to supply you with increased bandwidth, where available, only as you require it thereby providing a far more efficient utilisation of bandwidth. For instance, searching for a Web site on Google would not require large bandwidth, yet downloading a large video clip would require a lot more bandwidth and thus will allocate you more bandwidth only when you start downloading.
