Enter it with the country code +84. A number written locally as 0912 345 678 becomes +84 912 345 678, so drop the leading 0 after the country code. Vietnamese mobile numbers have 9 digits after the country code. The example is a format guide, not a real number.

Enter the number with the country code, pick a plan and pay by card. The operator is detected automatically and the credit goes straight to the phone. You do not need an account or a bank account in Vietnam.

Recharges are delivered instantly and cannot be reversed once they reach a valid number, so check the number before you pay. If the operator rejects the number, Slashtel resends or refunds you in full.

Prices on this page are in US dollars and include the Slashtel service fee. At checkout your card may be shown and charged in your local currency, and the exact amount is confirmed before you pay.

If the operator rejects the recharge, we resend it. If it still can't be delivered, write to esim@slashtel.com or message us on WhatsApp with your order reference and we'll sort it out.
