Giga.Tel offers Vietnam eSIM plans that include a phone number with the dialing code +7 and outbound SMS capability. The plans provide 10GB of data per day and are available in validity periods of 3, 5, 7, 10, 15, and 30 days, with prices ranging from $4.75 USD to $14.25 USD depending on the chosen validity. The numbers use the +7 code, which is not a Vietnamese local number, and SMS can only be sent, not received. Users should confirm the exact functionality they need directly with Giga.Tel.
