Question: Which selling SIM card can be used in Vietnam, Cambodia and Laos?

Answer: Viettel SIM cards can be used in Vietnam, Cambodia and Laos. You still use same phone number in 3 contries.
But remember that existing registered promotion package in SIM is not valid from one country to another country. It means that new fee (calling minute, data volume, etc.) is applied in current changed country that you stay. Especially, care about roaming fee because it is too expensive.
The better way, you should buy a SIM in Vietnam and use in Vietnam only, and to another country buy another one because each local provider try find the best local product for you.


Question: Is there any SIM that is cheaper than Tourist SIM (V90 SIM) with same benefit but its validity is shorter. Such as 2GB/day, validity is 7 days?

Answer: No, there is not.
We understand what you expectation.
But all network operators would like loyalty customer (monthly paid) so he make promotion package with his objective to that customer.
Currently, Tourist SIM is still the most attractive for shorterm customer such as traveller who could take advantage of that.
Moreover, telecom market in Vietnam have changed frequently, it means network operators's products (internet packages, ..) exist in short period. So sometime you perhaps see a cheap package that is mentioned on some websites but you could not buy at the moment.
