I went ot HCM for a week. I purchased an Viettel data-sim at the airport from one of the improvised counters, 7gb for around 350000 dong. It took no more than paying and putting the sim in my mifi decice, turn it on and ready to go for 7gb. We did not need to show our passport. I checked the balance by sending a text to the designated number and it stated 7gb indeed. No problems whatsoever, you're really done in a few minutes. The people at these counters seem to know how every type of phone in whatever language works. My partner bought a voice/data sim, same story.

Viettel has 4g everywhere in Ho Chi Minh except for deep inside buildings with thick walls, then it was 3g. Download speed was very acceptable, from around 3 to 7 mbps with bad reception to around 25 mbps with good reception.

I was worried that my simcard might stop working because we hadn't registered, but no problems. The cards seemed to be pre-registered and they had stamps on them.

People in HCM are all relying heavily on their smartphones. A lot of them have advanced models, you'll see plentyof iPhones 6 and above and the whole range of advanced Samsung Galaxy phones. Also be prepared for people to take your phone in their hands, be it to enter the wificode of a restaurant or the taxi-driver that wants to have a closer look at the address you found on Google maps. Don't worry, you'll get it back ;-)
