Honestly, I don't trust Powerroam. Here is the reason: In their offer they write '''Local 3G network, unlimited speed, unlimited data'. ''This seems to be clear. But all their 7-days offers in different countries are combined to one 10-country SIM too and there suddenly it reads: 'Vietnam 3G network, 500MB/day + unlimited 2G data.' 

It's a different offer, but for all other countries the offer of their single package is copied in this combined pack, only Vietnam is different! Of course, this means something totally different, but if you read it very closely both can be possible: They use the local 3G network (Mobifone according to APN), then degrade to 2G beyond 500MB/day and you have still 'unlimited data' with 'unlimited speed' first on 3G, then on 2G.

What Vinaphone's/GCS tourist SIM is concerned, I see this offer as confirmed and add it to the Vinaphone section of the article. A bit unflexible and hard to get outside of Hanoi, but a valid option without registration as it works for 30 days only.
