This deal would go down well with almost any traveler but especially with me, being from Canada, which has the most expensive mobile service in the world, It is for a local SIM card for Malaysia. I was quite happy to purchase this card with 30 days of unlimited data and local calls for only 40 MYR. I have the option to extend that too if I wish. This was in Malaysia but this affordable pricing is available throughout Southeast Asia in my experience.
Location: Any Digi phone shop in Malaysia
Cost: 40 MYR ($12.42 CAD) for 30 days
