Reliable network, worth every penny

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.​​​​​​​​​​​​​​​​

Poor customer service

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…

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…

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

Don't buy a Viettel SIM Card

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

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.
