Viettel Reviews 

Viettel esim is good as far as 5G coverage and speed is concerned but the store I went to in Hàng Dầu, Hà Nội charged far more than official price. In addition the staff cheated me by assigning a local number to my esim (without telling me) although I wanted Data Only. The reason they do this is so that their "associates" can send spam and scam texts. I was bombarded with "your data allocation has run out, please recharge now". My opinion is some staff at this place is untrustworthy. You want to do research on price and packages before stepping into this store. On the whole, while they overcharged me, the cost is still low compared to Vodafone International roaming.

To be honest, I am quite enjoying using viettel service during my stay in Vietnam. I was surprised by seeing so many negative reviews for them. Well, the reload process for foreigner is abit troublesome because they need you to travel to their local store to do the reload. Other than this, I’m quite happy with their service such as stable network and the cost is quite affordable.

I had the displeasure of ever interacting with this hellspawn of a service, when a person is born into life, they will experience all kind of emotions, joy, happiness, wrath, sorrow... Well i got to enjoy the latter, i got touched and molested my dad when i was 11, it affected how i felt and the way i considered myself. When he got sentenced, i was so happy that i will never go through such things again. Then WHY, the HELL, did i ever thought about using THIS service??
18 HOURS OF WAITING, ZERO SUPPORT FOR FOREIGNERS AT ALL!
I was waiting the entire day for them just so that i can watch the world cup while working abroad, but to my displeasure guess what? Poor handling, terribly advices and HORRIBLE negotiation and information. Even the person who was connecting me to different calls seems out of it, as i kept getting blamed for the delay even though i was waiting for the staff member whos supposed to install my wifi for 18 HOURS?
this service js garbage and any form of usage related to it should be considered high intensity torture.

After my Viettel SIM from the airport expired, I made the mistake of buying an eSIM from vietnamesim.com (operated by Gigago) — overpriced, poor coverage, and hotspot completely disabled on their “unlimited” plan. Couldn’t take it anymore after 5 days and went to a physical Viettel store to get a new SIM. Staff were genuinely helpful and the difference was night and day — strong signal everywhere, hotspot works perfectly. Should have just renewed with Viettel from the start.​​​​​​​​​​​​​​​​

I bought a SIM card with a plan and tried to create an account on shopee but couldn't because the number was linked to a banned shopee account. I went into the store where I bought it and raised the issue with them. They told me that I'd have to buy a new SIM card in order to get a new number. Ridiculous!

Bought a $12 sim at the HoChiMinh airport. The girl at the desk put it in and set it up. 30 days unlimited data and some phone calls included. Went from the ChiChi tunnels out of HoChiMinh, though Phu Quoc up to Hanoi then Sapa, then up to the border with China. Did not miss a beat all the way. Would highly recommend.

Very low skill and very poor attitude in store when I changed phones and wanted to move my number. A rude member of staff said it was not possible because my phone was American (it is not American) Then I went to another Viettel store who fixed it immediately. So clearly the problem is poor training and not my phone

I am a tourist in Vietnam and bought a SIM card in an official Viettel store in Vietnam, valid for 30 days and I can use 6 GB per day. No one told me that only 2 GB of this is usable nationwide and the other 4 GB is only usable in certain areas of the country. If I had known, I would not have bought the SIM card. I travel all over Asia and many other places every year, but have never experienced anything like this. I am disappointed and angry that I spent money on something I cannot use in Nha Trang. This is the first and last SIM card I have bought from Viettel.

Worst internet provider. Always have connection problems. With premium prices but quality can only described as frustrating bad. The only good service of the company is their mobile data service's range. The only reason they are still standing is because they have been in the scene for very long. Would recommend FPT as your network ISP. There price/quality is highly outclassed. Whilst having a younger work force and newer technology.

I bought a Viettel sim card when I got to Vietnam for travelling and it's very convenient to sign up the sim card. The connection was stable whenever I went to. Recommend this

I paid 20000 vnd for mobile credit that I did not receive. The customer support email just replies the same thing every time I ask something in English.

they treat their employees like a machines, not human. only work and work.

initial connection was very terrible but aftre complaining i was told how to make it better. much better now Thanks

The price is cheap. Service is spread nationwide with support from high-tech logistic system. Should you when you come to Vietnam
