My expectations were high for the Wiggy. A brief overview of it is as follow :

Why did I stop subscribing to the Wiggy services?
A simple answer... it sucks.
A more detailed answer...
A USB dongle is a something that you carry around with you when you are out from home and wanting to use the wireless broadband service out of you house.
The possible areas that you would expect to use your wiggy will be at the following :
a) Client's office (usually you are not allowed to use the corporate network)
b) at cafes or restaurants (to quickly download your mails and check things online
c) at malls (when you are waiting for your next appointment)
Wiggy fails at all these locations. Why?
In mobile telecommunication, there are two important site coverages.
a) Outdoor coverage
b) indoor coverage
P1 Wimax has been aggressively rolling out their networks to provide wireless coverage all over Malaysia. However, they have only been focusing on outdoor coverage which explains why you need to have your fixed modem place next to the window or someplace where you can still get the faint signal from outside. The frequency that P1 Wimax uses is 2.3GHz and with the bigger the number, the wireless coverage is smaller and will not be able to go through obstructions like your walls.
If you live in a simple housing area with simple house structure, you have a better chance to get the coverage as the signal will go through relatively lesser walls and steel structure... but if you live in an apartment, trying to get the signal from the center of the mall or in dense conrete based structure.. chances are... you will not get the coverage.
Another important note on the wiggy is, like most other dongles, it may be able to receive signal from a high powered base station or transmitter, but the device itself has very small transmitting power to send the signal back to the base station... so, its rather useless as well.
Wiggy is a good concept but it suffers from poor network coverage or cell planning understanding. I hope P1 understands this.. and work to provide indoor coverages as well. Unless they expect all users to sit by the side of buildings or in the middle of the road to catch the signal.
