I'm just a European traveller so I'm not an expert :)

My Mobifone SIM is still working now two weeks later anyway. The biggest problem I had with Mobifone was that the 3G network would suddely die quite often. First time I was left with GSM only for 16 hours, rebooting the phone or going into airplane mode then back didn't fix the problem. I got it to work when I put the SIM in another phone and then put back in my old phone and then fiddling with the settings for dual SIM. I don't know if the 3G network was down the whole time or not, the other times I fixed it by switching between active SIMs on my dual-SIM phone. Not good noticing the phone is stuck in GSM when you needed to do something.

Could be my phone but very unlikely as it works perfect on 4G/3G/2G with at least a dozen other European and Asian operators including Viettel.

I didn't think the SIM-cards at the airport were that overpriced, 200 000 VND for 12GB data, 50 minutes domestic calls and 200 sms/200 minutes to other Mobifone customers. They had some other options too. For Viettel I paid 50 000 VND for the card and 120 000 for 1.5GB data (I topped up 200 000 VND which left 80 000 VND for calls/SMS).
