[Buy two and get a 50 yuan shopping voucher] Vietnam SIM card | Viettel Telecom | Hong Kong delivery/collection

There is no problem receiving messages in Hanoi, better than expected. And buy one get one free is really great value.

Very good, iPhone is plug and play, the signal is very good, will recommend friends to get it

we bought 2, price was excellent, cheaper than Hanoi street price. I inserted into iPhone15 pro and worked immediately.but I had trouble getting it working with my Xiaomi 14t pro. it eventually worked when I unchecked the Volte box. otherwise, everything smooth and I will buy again.

easy to use and good price value the network is very smooth i will definintely buy again from KKday

Very good, receive the card in Hong Kong, work as expected when arrive in Vietnam

it was a good experience. need to add more centres for delivery

The delivery of the cards was very quick. The set up for the card was also simple. Great!

It is perfect for two of us to travel Vietnam 8 days with buy 1 get 1 promotion. The SIM card send us by post, we received after 2-3 days. Good connection everywhere in Hanoi and Ha Long Bay.

Received the cards within 3 days in the mail. Price was cheap, easy to set up. Make sure you turn on roaming on your phone.

Not the cheapest in market but good enough esp offer the earliest pick up in HK so I can insert the SIM into my daughter’s phone to save her the trouble as she travels without me this time. Pick up address states on KKDAY different from map location, which I later found out the company recently moved from one street to another within Kwun Tong. Received an apology from a sincere friendly staff of the company.
