Hey there. Its great to see a Finnish folks. I hope you'll enjoy your stay in Malaysia.

Penang is a nice place to be in. The main problem is the internet connectivity. You'll find the maximum speed the consumer can get is 1Mbps or 2Mbps at the most. Apart from that the connection isn't that smooth. You'll find some hiccups along but then you'll learn to bear with it and yes the connection isn't as great as in Finland and in Sweden. I've been to those places back in 1999/2000.

As for your second question , Well I would choose Celcom 3G personally. Its one of the best provider in Malaysia. On top of that you can pay RM 68 for their unlimited data package. I recommend you to go for Unlimited 3G/HSDPA/DATA as there is no any form of contracts or so. So you may just cancel it
