I had a Viettel SIM card with 3GB data package for 3G internet for 1 month and I paid 250,000 dong. It was enough for a whole month. I made some local calls, and almost every day I used Google Maps, and email and occasional surfing the internet. In some remote mountainous areas there may not be a signal, but I only had a problem once on the route between Lai Chau and Son La city. In some areas you may have a problem with roaming.
