How much money am I looking at for a SIM card - need 2 weeks and at least 2 GB data (is WiFi readily available in public areas and/or hotels) and for calling texting, need an incoming number (not data only) and preferably 100 minutes, but both domestic AND international.
Do any companies have nano SIMs available, in HAN?
Also, saw conflicting things when searching in English. Is LTE available in Vietnam?
