Local Mobile Services in Vietnam: what actually matters to know
Short answer
Purchase a local SIM card at an official carrier store in the city for reliable service and cost-effectiveness compared to airport options. While some apps allow registration with foreign numbers via WhatsApp verification, a local Vietnamese SIM is often necessary for services like Lazada.
From real experience
A local Vietnamese SIM card is often required for registration on platforms like Lazada.
Any local operator's SIM will suffice. Obtaining a Vietnamese bank card without a residence permit (WНЖ) is highly unlikely; consider asking local acquaintances to make online purchases with cash on your behalf. Cryptocurrency offers an alternative payment method, but ensure your Russian bank cards are compatible with crypto exchanges, as compatibility can change, and some cards may be blocked.

SIM cards can be purchased at the airport upon arrival in Vietnam.
While purchasing at the airport is convenient, prices might be higher than elsewhere. Tourist SIM cards offering unlimited internet are available on street corners for around 200,000 VND and can be obtained without a passport. For more options, including eSIMs and physical SIM cards, consider visiting a salon and presenting your passport.
