Cheaper than buying a roaming package from my local provider. Network was stable throughout my stay in Vietnam, including in quite remote areas. Easy setup, no usage issue at all, and 5GB limit per day was more than enough for me. I didn’t get the QR code immediately after I bought the e-SIM, but customer service was so quick to respond when I reached out by email. The only minus was that I didn’t get any voice call minutes as advertised, but I didn’t really need them anyways. Still 100% recommended.
