1. How does data card work?
When you choose Vodafone data service, you don't need to worry about its quality. If you find yourself in an area that's not yet covered by Vodafone 3G broadband, you'll automatically switch to the GPRS network with a lower speed. To get connected, you simply need to do such things:
- Install the software.
- Insert the Vodafone mobile connect data card with SIM when prompted.
- Create a profile.
- Active dashboard and connect.
2. Can I use my USB modem with more than one PC?
The answer is yes, the USB modem can be used interchangeably with more than one pc. The only thing you have to do is installing the included software on each pc.
3. When I am moving, such as in a train or bus, can I use Vodafone mobile broadband?
Yes, Vodafone mobile broadband provides us with the best available connection within Vodafone's 3G mobile broadband coverage areas. Slower speeds can be expected outside Vodafone's broadband coverage areas.
4. What is the maximum capacity of a Micro-SD Card that a Vodafone USB modem will take?
Its maximum capacity is 4GB.
5. Can I manually switch my Vodafone connection between 3G and GPRS?
Yes, you can switch your connection between 3G and GPRS just with a Vodafone mobile connect dashboard. If the version of your software is 9.1.2, you can manage connections on dashboard. According to your version of software, you must do different things to switch it. To find out which dashboard version you have, go to 'help', and then 'About Vodafone Mobile Connect'.
6. How can I improve my speed while connected?
The speed of the connection depends on various factors such as coverage, your location, your hardware and software, the source of your download and general network and internet traffic. You can try to get better signal to strength your connection, or change your security settings and firewall applications that influence the connection speed. You can also use the longer cord as the cord acts as an antenna for the modem if you're using a USB modem. Anyway, there are many methods you can improve your speed, and you must choose the best way according to the actually situation.
7. Do the USB modem and Express Card support the speeds of future network?
Yes, both devices will be able to take advantage of future downlink network enhanced up to the 7.2Mbps standard. However, all Vodafone services are subject to current network limitations and availability.
